B414 issues.... again

Hello all! I posted back last winter about a b414 I picked up.
Didn?t have 3rd or 4th gear or high range. Well, I got a donor
tractor from a junkyard with a good gearbox. I swapped out all
the transmission gears, resealed entire trans, diff, and front
bellhousing. Also put a new clutch and friction disc in.

Well.... I ran it for awhile, clutch worked, just don?t try to push
the pedal to stop. Clutch wouldn?t disengage, so I parked it
against a tree and put it in gear and just left it run(someone on
here suggested that). Made no difference. So I use to to cut
my field, in 3 low it started skipping out of gear, till finally one
time it stopped moving uphill and just started grinding and it
almost rolled on top of me when it drifted backwards and the
brakes locked up. Also, you cannot get it to go into high gear
unless you shut tractor off and put it in then restart, I think that
has to do with the clutch not working as well.

Well after sitting all winter staring back at me, I decided to give
it a 3rd try.... going to pull it apart again when it warms up.
Needs a head gasket, and a good degreasing again.

ANY SUGGESTIONS on the gearbox slipping issue, clutch
not working and the high/low issues? I just want to get this
thing up and running so I can actually use it, not let it sit in my
yard and be a big red lawn decoration

Thanks everyone! You?re always appreciated for the
knowledge and advice that you give

A brand new clutch and pressure plate that you just installed will not be stuck. As soon as the clutch did not work, you should have immediately taken the tractor back apart to find the problem, not tried to drive it.

Letting it run against a tree is just plum dangerous. If it doesn't come unstuck right away, leaving it for any length of time is just a good way to break the tractor, get hurt, or destroy some property when something inevitably gives.

The most likely reasons for your continued troubles are some combination of bad parts and incorrect assembly. A very common mistake made in installing clutches is putting the friction disk in backwards. Most clutch disk hubs stick out further on one side, and if you put that side facing the wrong way, the clutch will not release from the flywheel, because it is pinched between the flywheel and the pressure plate.

The clutch pedal also needs to be adjusted for proper free play. Too much and it will not release. Too little and it will not engage fully, and burn up the throwout bearing very quickly.

Thanks for the reply. I said in my post, “3rd time”. That’s because I have had the tractor split, taken apart and re assembled EVERYTHING 3 times and something still isn’t correct. I have tired all ways of assembly on the gears and friction disc. Yes the disc only fits one way, if you put it on the input shaft during assembly the wrong way it obviously protrudes too far from the clutch to be correct.

I have also adjusted the pedal as per the IH manual instructions, have tried more and also less pedal. Once the weather brakes here in Pa, I’m going to tear the whole damn tractor apart again and study everything again and see what I’m doing wrong. I just can’t fogure out for the life of me

Hi, I assume your B414 has the dual stage clutch. Half way stops transmission, all the way to foot rest stops transmission and PTO. Those dual stage pressure plates require special setup procedures before installing on flywheel.
Did you do all the adjustments on the pressure plate? Also check the ware on the adjusting nuts on the pressure plate.

Re jumping out of gear, did you check the shift rails, springs and balls and shift forks?

Yes I did. When I pull it apart again I will reset everything back again. When I did the gear change, I used the shifter assembly from the donor tractor as mine actually had 2 forks ground completely off

Hi see older link in changing clutch on 354 same as B414. I have the older post with the photos.

See attached photo of the critical pressure plate adjustments. On our 434(same clutch) the shoulder of the adjusting screws had
worn grooves in the pressure plate and turning the screws 1/4 turn put the shoulders of the screws out of the worn portion.

Older link 354 Clutch same as B414

Alright JimB you re the expert.... I split the tractor again this week. I put the friction disc, pressure plate and flywheel together on my bench. I made the "jig" as per the manual, and set the fingers to 2 and 25/32. Also set the pto clutch to 80 thousanths. I put it in my shop press to confirm that the friction disc will spin when pressure is put on the pressure plate fingers. The disc is free when fingers are depressed. Put it all back together to test, set the pedal to have 3/4" of free play. Started the tractor, put it in low range than 1 st gear with the clutch pedal DEPRESED, and the tractor took off. Clutch is still not working.

I attempted to put a crescent wrench on the fork shaft, tried putting some pressure on the fingers with the throw out bearing, tried test again, tractor still takes off.

I pulled it back apart for the 5th time, took the pressure plate, friction, and flywheel off. Bolted all together in my shop press. Used the shop press to simulate pushing the clutch pedal down. Wa la! The clutch works when in my press, but not when the tractor is together. I pulled the pilot bearing out, it is not seized, it fits over the input shaft of the transmission. The input shaft is not binding, missing, rough or otherwise has any problem when re assembling the tractor.

I am out of option, ideas and patience at this point.....
