oil filter leaking mf-65gas

Any pointers on changing the oil filter on the gas mf-65, it seems to either leak at the gasket or the nut that you tighten. How muchtorque does it need to seal?

Does your tractor have the metal canister oil filter cover or a spin on filter?

If you have the canister oil filter:
Check canister body to be sure it's not been over tighten in the past, the canister could have been bent out of shape. No burrs on the bolt or canister edges.

Did you buy a filter from a MF dealer or after market. The gaskets might be of better quality with MF oil filter.

I would take the canister apart and clean all mating surfaces with some type carb cleaner or other material that will insure all surfaces are clean.

Does your canister still have the washer and spring inside, this spring insures the oil filter is pressed against motor block.

If all else fails you might try, buying a second oil filter and using the gaskets from the second oil filter along with your current new gaskets. If you have bent or deformed metal surfaces, two gaskets might fill in the gaps. However, I am not high on this fix, you need to find out why the proper oil canister will not seal off. The canister should seal properly, any leak in this area could cause you to lose your oil and ruin you motor.

Let us know what the problem was.

My to35 has leaked before when I changed the oil, normally I just loosen the oil filter bolt, turn the canister around some,move it a little, then tighten and it seals off.

metal cannister-there is no spring to press against frame. used NAPA filters.

Are you sure you have the old gasket out and the new one in correctly??

rkh,
trust me, you need to get the leak stopped first, but there was a spring and washer in there at one time.

procedure: insert the bolt with rubber gaskets into the canister then the spring, then the washer, then filter.

the spring forces downward pressure on the oil filter and keeps it tight against the tractor block.

if you do not have the spring and washer inside the oil filter canister, the oil filter can just flow up/down the center bolt, your oil will go around the filter, not through the filter.

without the washer/spring you in effect have no oil filter.

but, you must get the oil filter canister to stop leaking first, then worry about the spring and washer.

what happens: when draining the oil out of the oil filter canister, the filter falls off and the spring and washer slide off into the oil and no one checks to be sure they are back inside the canister.

I got my spring and washer at the local Massey Ferguson dealer, they had to order them.

many have changed over to a spin on filter, but I use my tractor, sometimes in the woods and I have had limb pop up under the tires and hit the oil filter canister as it is mounted low on the side of the tractor. you could slash a spin on filter and lose oil pressure in a minute and you never know it.

I have had this problem on more than one filter of this type and it is usually caused by the replacement rubber gasket being too wide for the groove in the filter housing. My solution is to take the old assembly off and replace it with a spin on adapter and filter. I use my tractors in the woods and never had a problem. If the filter springs a leak believe me you will know. I forgot to hook up the 1/8 oil pressure line once and before I could shut off the engine I was covered in oil, so don"t think there is any danger of running the engine dry.

is this for the gas engine(spin on filter)?

anybody have the diagram for this assembly? I've had this for 7yrs & never seen this spring. is there a part # for spring & washer?

try this site
it is the agco site for ferguson 35 tractors

shows the two part numbers for the oil filter canister spring and washer to be as follows:

1750585m1 spring oil filter
1005438m1 retainer, oil filter cover spring

good luck,
this is the only place I found them as most part houses would not have these factory parts.

as I said I had to order my spring and washer from the AGCO dealer

My 150 with a z145, didn't have the spring & washer either. I went to my storage bins "coffee cans" and found a spring & washer that worked, nothing fancy needed.

I'm sure

What spin on adapter fits the g176 gas engine?

whats length of spring & how much tension does it have?

That is reason I bought my spring and washer from the dealer,

Since I had never seen them.

I did not know the length or spring strength or size on the parts.
Last thing I wanted was to try and fix something then starve the engine for oil or do other damage.

Good luck,

Really can't answer that. Just enough tension so you can get the bolt started. It's been 6 years since I installed spring and washer.

The z145 does not have a full pressure filter system, only a trickle goes thru the filter at any time. Sorta like the system on the old 9n's.

$20 plus shipping Plus tax for spring.

Hi
Are you double sure. Have had tractors here of different brands for service. pulled the filter, took out old ring put new one and filter back on , guess what It leaks.
well somebody never took the first old ring out and jammed it all up so tight, with the second,I had to chisel the old ring out to get back to the clean seal ring groove. some places they put these filters you can"t tell that easy.or get in there if a loaders fitted.

I took apart, recleaned and put together & no leaks(and no spring). I would like to put the spin adapter oil filter on but I have the G176 Continental engine & dont know if they make a kit for this engine.

ebay sellers say the part # 1051113 will not work on the continental gas engine G176 but one MF dealer says it will? anybody know?

I'm all the years we've had our 165 (continental gas engine) the filter only leaked once. It was a filter from the dealer and after a brief phone call, they suggested we stretch the gasket done so it fit better in the engine. Did that and it never leaked again.

Thought about putting a spin on filter on, but it's really not a big deal the way it is so we've just left it. The filters aren't hard to find and they're not expensive either.
