Got the onan/Kubota engine swap all done this weekend. Everything worked, runs fabulous. Looks like factory. The problem is, I put the motor in backward. Attached the drive to the wrong end, so it turns backward. The drive was hooked to the flywheel on the Onan, so that's how I did it on the Kubota. Now that I think back it's painfully obvious, but not when it was going together. Worst part is in the beginning I had planned to hook to the dampener end and changed my mind. So now it's back out with the engine and turn it around. Oh well, my dear departed dad used to say anything worth doing is worth doing twice. I may take a day two to pout first.
 
Back in the 50's my dad took an American LaFrance water pump and it turned the wrong way using the 8N PTO.
To correct it, you had to remove the ends of the pump and put them on the other side.
We took it apart and reversed the ends.
It still would not pump.
Then one of us realized that we had reversed the middle also.
Did it right the second time and it pumped like a firetruck.
Still have that pump in my barn.
 
Do you remember a set of needles you rebuilt for a guy ?? An oil cooler Incident and a blown up Cummins motor also come to mind
 
I have a knack for putting things in backwards the first time, seems like you would have a 50/50 shot at getting it right, but for me it seems to run more like 90% it will be wrong the first try.
 
I am not familiar with with the hydraulics on your machine but I do know on many gear type pumps you only need to swap a few parts around to convert them to run opposite rotation.
 
(quoted from post at 09:57:54 02/28/22) The reverse cam sounds like the perfect solution. Just run the engine backwards.

To reverse that engine I am guessing he would need new cam, oil pump, water pump, starter, maybe injector pump...

I do it for a couple reasons, one is I
think more is learned from mistakes than
successes. You can do projects many ways
successfully and all are good ideas, but
the failures when shown are the ones that
can save time and money.

Also, I don't have a problem laughing at
myself. So why not share it
 
I put a 329 Deere combine engine together out of time once. Retimed it and it ran great but kept starting harder and harder. Finally pulled the engine and then the head. Lets just say that pistons and valves do not play well together. I had a helper on that project so I tend to blame it on him whenever he is around.LOL The price of education is rarely cheap. Tom
 
Yea i did. In a Rush to get one of my super nice 706's done for the big tractor pull to be used for main track pull off tractor i put second gear on the lower shaft in backwards , once in second it would not come out so i had second low , second high and second reverse I was so mad at myself over that but was glad it was on my tractor rather then a customers . They came to me wanting my 706 and my super MTA and my 370 I H disc to work the track . Yea i got suckered in . To get the track ready i spent two days helping work the track to get it dried out with the 706 and disc then three days during the pull . When i asked if i could get just TWO passes for the War Dept. and my one daughter you would have thought i had asked them for a million bucks . Then came the fight over fuel . They were giving away only ten gallon of fuel to each of the tractors that were used for dragging the big boys around with , i had two working tractors and they only wanted to give me 10 gallon , i had already sucked up around 45 gallon of gas between the 706 and MTA running around for three days . I said fine and if you think that five in each tractor is going to last two more days your wrong not counting what it has cost me to get everything up here and what it is going to take to get it all back home . So i'll just load up now and take everything home no and let you figure out what your going to use for a disc and main pull off tractor . Working that pull was the second dumbest thing i ever did. Then they had the nerve the next year to come back and ask me again.
 
I expect that 5 gallons of fuel in a gas 706 lasts about as long as 5 gallon of gas lasts in my gas 4020 and I have a Farmall 400 so I know how long 5 gallons would last in a MTA.
 
Had something happen to me the other day,more of an accident tho.Was reistalling axle housing assembly onto the Deere and had to reposition the assembly on front end loader forks.Had final drive gears covered with a garbage bag so didn't see the gears.Went to move axle housing,final drive gears turned and caught the end of my finger.Lucky for me I had some help with me and was able to turn gears back the other way,releasing my finger.Woulda lost the end of my finger had gears kept turning.Boy was I mad at myself.

A friend I pulled garden tractors with pulled the transmission and differential apart for some reason. In the haste to get ready for a pull, he did not try it out, just loaded and hurried to the pull. His turn to run, pushed it to the line, started it, in gear, revved it up good, let the clutch out and bang!!. He had the ring gear carrier in backwards. He hit the sled pretty hard. On most early Cub Cadets you could flip the carrier over and have 3 reverse gears and 1 forward.
 
John have you got what you need to get off the crank end, I have all sorts of pulleys or crank adapters.?
 
I was going to have an adaptor made, but if you have one that works I would buy it. My number is 320 492 9077
 
I bought this little Tough Built with no motor so I could do a KUBOTA conversion. Got my engine up there and sure enough forward on the hydro pedal was reverse and reverse was forward. Had to go find the original engine and like your they ran the tractor off the air cooled flywheel end and the rear mower off the work end Same mounts and just turned it around and drove off the front crank pulley. Nice tractor now.

I put a Lister diesel in an Owatonna skid steer many years ago.Very simple change.I had the direction right,but the old Wisconsin turned 34-3600,and the lister turned 1850.The pumps didn't like the low RPMS,it howled a lot,and it was the slowest thing you ever saw.Slow bucket,slow boom,and really slow travel.The only guy that never does anything stupid and wrong is a guy who doesn't do anything.

Do you have long stub shaft for a 20 hp honda??
I wish the stub shaft I have on Terramite with 20 hp honda was longer to I could have access to coupler between engine and hydraulic pump.
 
A person once asked the question, What is the stupidest thing you have done. I thought that that was a stupid question because most people will not share the very stupidest thing they have done. Its almost like asking have you ever committed a felony. But we all feel your pain. A quote by Jack Nicholas, Show me a man who doesn't lose a golf ball and I will show you a man who doesn't hit it very far. Keep swinging, you haven't fail until you say I QUIT.
 
Not enough time to admit all of my mistakes! Just wondered about your set up? Could you just change the control linkage? My White backhoe had forward and reverse throttle pedals. I grew up on a Case 580 and was used to the FNR lever to the left of the steering wheel. Since I am somewhat dyslectic I could not get used to the pedals and always pushed the wrong one. So I spent a day and made my own FNR control lever. I did finally get the wife thing right on the third try! And two fingernails are just about heeled as well.
 
Well the Mta on 3x16's was a great time keeper, put 20 gallon in and hit the field and when you ran out it was lunch time , come back and dump 20 more in and when it ran out it was dinner time , come back out and before it ran out so you did not have to walk back you headed for the barn . I never found my 706's to be quite that bad . I pulled 4x16's in our ground and in sod fourth low at between 8-10 inches deep and i could set in the saddle from after breakfast till way past dinner time on a full tank . In corn ground i could step it up to high first and run. I kept it in tune timing set dead on the money and i ran high test same as what my trucks ran on , My 73 F 250 was not sporting the boat anchor 360 it had a 428 S/CJ four Bbl. with a 11 to 1 compression ratio , my 78 F 250 after the bottom end went to lunch for the forth time got a 460 built to 1971 spec's and it had a 11 to 1 , so when filling up the truck my tractor tank got the same 105-107 octane fuel for supper . I hated confusen the girls at the gas station with two pumps.
 
If I had done something as dumb that I didn't want to talk about it, I would certainly not publish it for everyone to see. Sorry.
 
Jon , I feel Your pain ,,.. And I know You have sympathized with mine over the yrs . Another thing My DAd would say ,,.Those that do nothing never make mistakes .., And THEY NEVER MAKE A DIFFERENCE to anyone or anything except for all their wasted possibilities to society .
 
I had a 71 Lincoln Town COUPE with that hot rod 460 in it. Only thing to pass it on the interstate was a Hayabusa M/C. I pulled into Barstowe to gas up and he was there. He said that was the fastest he ever rode that bike. I thing they were capable of 180 plus.
 
Back when we had both gasoline and diesel fuel tanks a young employee thought he would help out by filling the Cat 65 and disc parked next to the gasoline tank. My 80 year old employee came to work and took off with the Cat and called about an hour later with tractor engine problems. Cost about $12,000 to fix engine and basically my fault.
