MF 35 replacing points condensor

I have a MF 35 gas fuel tractor. A couple of days ago I had it running and it died. Previous to this, it seemed that it might be missing.

I have replaced plugs, wires, distributor cap. It still won"t start.

I have a condenser & points which I now intend to replace.

How do I get the dust cover off the distributor?

This is my first work on a distributor. There appears to be a screw on the side of the distributor case. Is this what releases the dust cover? Didn"t want to try it without knowing for sure in the event that was what is used to move the point setting.

Also, will I have to try to set the timing on the tractor after replacing the points?

And would removing the distributor itself to replace the points ruin the timing?

My distributor is a snap clip style and NOT the screw style cap.

Thanks so much in advance for your help. Sorry I get to look so "dumb" here.

Hoping to get this fixed sooner than later as it"s cold and I was in the process of trying to move large bales of hay to my goats when this thing died.

Thanks for all the replies. I just hate looking like a "dumb chick", LOL. Funny thing, I had tried just pulling the dust cover off the day before I posted, went back out after I posted my original message and tried just pulling it off again and wallah! Off it came.

As to the points, I did not see a 'pill' with the grease in it but had wondered since I noticed some lube under the rotor.

As to the electric conversion, I've already replaced so much and bought the parts to finish this job out (I HOPE) but will definitely look into this if/when this needs to be done again.

Thanks for the detailed info too on replacing the points and condensor. I was secretly hoping someone would add more that I had asked. I plan on working on this today since we have a balmy 54 degrees anticipated. I didn't know to set the points while they were open either, so appreciate that. When I looked yesterday it appears the points are totally closed, but I can move them. Sort of a grayish look to them where they make contact.

I enjoy my tractor. I've had it coming on two years now. Just bought a hay spear for it that I haven't yet been able to get on because the brush hog bolts seem awful tight and possibly painted on in place. SO right now I use a chain and heavy duty web tie down around the large bales to drag them into place. Once I get this running again tho, my next project is to get the hay spear on.

Thus far I've only had to replace the alternator belt, which was about shredded when I bought the tractor, a battery and a water pump. Now points and such. But still has been a wonderful investment.

I'd like to get this thing back to new like condition. A refurbish job if you will..... and then maybe sell it so that I can buy a bigger tractor. I need more horsepower for the things I am building this farm into and would like the capability of cutting and baling my own hay at some point down the road.

Thanks again. I may be writing more later after I look at this and see what other damage I can do here. *wink*

Thanks,
Jennifer

if you have a 3 point hitch, you shouldnt need to unbolt anything to drop the bush hog off. the lower arms will have a lynch pin on each side, its just a pin with a spring bail, flip the bail and slide the pin out, then the top link should also have a pin. set the mower down on the ground, raise and lower the hitch to get the arms loose, they should pull off to the side, there may be a sway bar that you need to loosen too. if you can post some pictures of the hitch, we can figure out whats up.if you dont know how to post em, email me the pics and i'll post em for ya!!glenn

OK, what are my points supposed to be set at???? I set them at .20, still won't start. I'll have to see if that is in my manual or not once I get chores done as daylight is leaving for the day.

Also, I read somewhere that you can test the coil by taking the coil wire off the distributor cap, holding it close to the metal on the tractor and seeing if you get a spark????

I tried that and see no spark. So I need a new coil? Easy enough to put on if that is the case, but wanted to check.

Also, my battery is low now, so will have to charge it overnight and see if that helps.

Will get pics of the back end too for hay spear issue, but need to get it started first.

I am having fun learning, but this is frustrating just the same. LOL

Thanks.
Jennifer

It"s not 0.2 inches! It"ll never start there. It 0.022". You are ten times to big and so the coil never charges with that gap because the points won"t close.

duh, boy my mind must be slippin. if you look at the column to the left under research and info, select tune up spec and also take a gander at tune up giude. the points for your massey 35 look like .022, so at .020 you are in the ball park. the tune up guide has a lot of info there too!!!!

Thanks! I'll check the left column for the info you suggested. I did notice in my book today that the points are supposed to be at .22.

Just came in from testing the circuit for power to the coil. No spark at the points and no power to the coil. The battery however is low and goes down to 4. something when I try to crank and starts at 11. something on the battery before cranking. I have yet to charge the battery so is my next step. However, I am also guessing that the ignition switch might also be bad????

How hard is it to get to the ignition switch for replacement???? If it ends up needing to be replaced once the battery is charged?

does yours have a key switch and push button starter or a pull on switch? either one is easy to change. you can always go to napa auto parts and pick up a switch that will work. i would do a little more snooping with the test lite first, you could have a wire that broke off or just some corrosion on a wire terminal. follow that coil hot wire back, keep testing at every connection until you get thru the ignition switch and end up at the battery. when you do find power, what ever is past that point is where your trouble lies. dont waste money throwing parts at it until you know for sure what the problem is!!!!

OK, playing with the test lite. First issue: had to clean the battery cable on the positive terminal. Wire from here goes to a part on the left side. Cleaned this terminal too.

From there I traced a wire back to the push button start and a wire to the battery amp guage on the console.

There is only ONE wire coming into the push button start mechanism. Should there be a wire going from the push button start to the ignition on switch?

The reason I ask is that I do not see a direct line from the battery to the ignition on. There ARE three wires (connected at two points on the ignition on switch) connected at the ignition on switch, will head back out shortly to see where those go to but no light on the test light on any of those connections.

sounds like you got no power going to the ignition on switch. the push button starter switch may have an internal ground, which would explain only one wire, the switch grounds the solenoid, engaging the starter. you will need to do some more detective work and floow the wires from the pull on switch, one side will lead to the ammeter and on to the ignition coil, the other will wander around till it gets battery power. the problem seems to be in the wiring from the switch to the battery, broken wire, bad connection ect. does the tractor have headlamps? and do they work if you turn them on? i

One more thing, the tractor DOES have head lamps on it but they have not worked ever since I have owned the tractor.

I was looking under the hood last night and saw why the odometer does not work: No cable there.

I'd also like to fix the fuel gauge which I am assuming right now without investigating is a need for a new float. Tho that too might be a wire issue, don't yet know.

OK, I have followed the 'current' on the wires and have found a point of issue:

The battery wire ends up taking me to the battery gauge that sits next to the steering wheel. I have power going IN to that gauge, but no power going OUT of that gauge.

The needle in the gauge sits in the middle on 'zero'. I tried starting it and the gauge needle does not move. I was making the assumption that when I tried to start it, the needle would move indicating a lowering of the battery's power.

#1) Can the battery gauge be popped out of the 'console' from the top? And if so, how to do without breaking anything. Or does this have to be unscrewed from underneath, which looks difficult due to hands, position, room to work, etc....

There IS and has always been some level of condensation in this gauge and the tractor has been sitting outside so I am assuming it is possible water got in places that may have created an issue????

I was hoping there was a way to easily pop the gauge from the console to mess with the wires as this would be easier.

#2) The wire coming OUT of the battery gauge does eventually lead to the ignition start switch so thinking the wire or guage itself may be the issue.

usually the gauge is held in my a horseshoe shaped bracket, two maybe 11/32 nuts need to come off, the braket will come out, then the gauge comes out the front of the dash. sounds like the gauge may have given up the ghost. in a pinch you can run a jumper wire across the two posts, and see if it powers up the rest of the tractors electrical system. you can get an amp gauge from napa pretty inexpensive, unless you want a "correct" one for your tractor. you can make up a nice little jumper wire with some 12 gauge insulated automotive wire and two alligator clips. one on each end of about 6 ft of wire, you can put power all around the tractor for testing things. i think you are on the home stretch now!!!!!

Glenn, you said "Homestretch"?

More like HOMERUN! YIPPEE! Nothign SWEETER than the sound of my tractor starting! :)

I picked up some alligator clips and the 12 gauge wire per your suggestion and jumped the power in to the power out on the amp gauge. I almost didn't try to start it because I just KNEW it wasn't going to start. Bracing for yet another disappointing 'non-start' I pushed the start button and music to my ears, that baby started up quicker and ran BETTER than it has run in the 2 years I have had the tractor! New points, condensor, plus, wires, etc..... really helped as well I think!

I have been laughing and grinning since last night over this and how GOOD it feels to have my tractor back, as well as pride in the fact that with YOUR help and the help of this forum, I got it running! Still beaming!

My tractor got a hug and a kiss and a love pat as well as appreciation for itself! Silly perhaps, but that tractor? Man's (or in this case) woman's best friend! :)

Thank you SO MUCH to all who offered input!

I'll post here later today in the same category on the hay spear.

What has happened there is that on one side the arm that comes from the tractor to the 'ball' near the pin on the brush hog has come off the 'ball' and prevented me from being able to pull the pin on that side to release one of the points on the 3 point hitch. I tried hitting it with a sledge hammer but I think that is just trying to bend the arm. So will need some ideas on how to get that back onto the 'ball' so I can release the pin to get the brush hog off and see if my hay spear fits as purchased or if I need to weld some modifications to it.

Thanks again! :)

great job jennifer, glad you got er running. always better to track down the problem than to just throw parts at it. ya done good!!! if i read right, sounds like one of the lower link arms came off at the mower on your three point. if the mower is sitting crooked , there is a lot of pressure on the other link arm. you may need to wiggle the tractor a little to get the pressure off the other arm to release it. be careful if its got tension on it, the other arm should be wiggle loose. if its tight, it can pop off hard and hurt ya. the last resort would be to unbolt the backside of the pin on the mower to release the other arm, reposition the tractor, then hook back up.

I noticed in the note above that you set the points to 0.2 inches. That"s almost 10 times too large point gap.
The points should be set to 0.022". If you set them to 0.2" they will never close and you"ll get no spark. Go back and set them to 0.022"

Yes, thank you. I just missed the 0 in how I wrote it. Right now it is actually set at .020 vs .022.

Thanks for the reply.....

I have not yet figured out an 'easy' way to get to the ignition on switch. I'm going to spend more time today trying to dissect an easy way to get in that area to more easily see and work. I bought a new switch 'just in case' but will return it if it is not the issue.

From what i have been able to deduce at this point, I see 3 wires going to the ignition on switch. I have yet to figure out which one is bringing power to that are but no power is on either side of that switch.

I have seen that areas not getting power do so once I clean the terminals. So maybe it will be as simple as cleaning all connections along the way.

I've been tinkering with this as weather and time permits but will have to spend a little more serious time on it today as it is getting old dragging hay to the goats by hand! LOL

Will do and will check for corrosion.

As to my starter switch....

It has a push button start and a white pull out 'thing' I have to pull out before hitting the push button starter. What year model would that make my tractor (year range)???? I'm thinking this tractor is mid 50's to early 60's???

I know the battery has juice and the coil does not, so someplace in between.

I DO appreciate ALL your help, btw. Thank you!

jennifer, before i'd change the coil, check if you got power going to the coil. if you have a test lite, (looks kind of like a pointy screwdriver, has a built in lite bulb with a wire coming out the handle, alligator clip on the end.) put the clip to a good ground on the tractor, shiny bolt on the engine, coil hold down bracket, anywhere you can get a good connection, then turn the ignition on, touch the test lite to the terminal on the coil opposite the terminal that has the wire going to the distributor. the lite should lite up. if not, you are not getting power to the coil. then there is a problem in the wiring going to the coil.

As an added thought, I replaced my MF-35 points and condenser with the Electronic Ignition Conversion Kit and new coil from ytmag's store a couple of years ago. Greatest thing ever, gave it more power and better yet, never have to mess with settng the points again.

Did the same ,,,Converted to electronic Ignition on DC CAse.. Works great ,, UNTIL BATTERY gets weak and old ,, Tractor cranks well enough to start on old mag system , But not enough fire gets tru to stater to fire up engine ,, Must Always have strong battery or a pull ,, Or hand crank works as well , As long as starter motor is not using all the juice ,,, Have You ever had similar condition ? ,, Thanx Jim

jennifer, after the cap and rotor are removed, ike rrlund stated, the dust cover just lifts straight up and off. you may need to get in there with a small screwdriver and pry gently around the dust cover to remove it. be careful so you dont break it, its plastic or bakelite. once its off you will see the points and condenser. the condenser is held on with one screw on the metal band strap. remove that screw and the condenser will come out, careful so you dont drop the screw down in the distributor, a magnetioc screwdriver helps here. follow the condenser wire to the points, there should be a nut there at the connecter, loosen that and the wire comes off. the points are held in with two screws also. remove them and the points should lift free. install the new ones in the reverse order. there should be a small pill in the box with the points, it contains a little bit of grease. that goes on the points at the little block that rubs on the distributor shaft. that part of the shaft will be square if its a 4 cylinder. after you get the pints and condenser in, you need to bump the motor over so the points are open at the widest gap. use a feeler gauge to set the gap on the point contacts. the points will slide toward and away from the distributor shaft, one of the screw holes on the points will be oblong to allow this. set the gap so the feeler gauge just has a little drag on it. and thats about it. you should not have to reset the timing, it should be real close, dont loosen the distributor and try and turn it. that will alter the timing and it will need to be reset. my e mail is open if you need any other help. good luck!!! glenn

Dust cap should just pull straight up off. Might be stuck down,there's a gasket in there that can set up with age. Tap around the edge of it while you pull up.
