IH B414 repair/restore issue

Hello all! Before I start I?m going to apologize now for the log rambling post. Also hope it?s posted in the right spot. Thanks!!
I had just recently traded my 51 8n for a 66 b414. Guy I traded said it didn?t have high range or 3-4 gear. Well I got it home, started tearing it apart. Found half the gears on the cohntershaft ground off, the upper sliding gear bearing was toast and 2 of the shift arms were also ground off. A friend of mine pointed me to an old ?tractor junkyard?, more like a gold mine. I went there and bought a used casting with all the gears from the bellhousing to the axles. It was a 63 body. I swapped the good gears and shafts into my casing as the 66 had the larger brakes. I also put new seals, fluids, clutch friction plate, and pto/clutch housing in as well. Got it all back together, fired it up and it wants to drift forward when in neutral and the clutch depressed. Also I can?t get it into high range, just grinds away. When i do get it into gear in low range it wants to take off or if it?s in reverse it will just bog down till it stalls.

Any one have any suggestions or insite? I?m a mechanic for FedEx and work on Mercedes sprinters all day long so I shouldn?t be having this much problems. This tractor is a screw driver compared to a Mercedes which would be 20v drill..... haha

The top shaft intermediate bearing may be failing causing it to drive through the bearing. The master clutch is either out of adjustment, or assembled incorrectly, or the pilot bearing is seizing up. The disk could be warped from some force being needed to get it together. Jim

Thank you for the reply!

All the bearings were free and had no play when reinstalled. If they felt bad I would have replaced them.

The friction plate only goes into the clutch one way otherwise it will grind into the flywheel. It may need adjusted, I know In the shop manual it had the procedure in there but I tightened it to the flywheel and let it set where it was.

I put a new pilot bearing in when I did the rear main seal.

Disc warpage could be possible, but it actually whent together very easy, got it close, started a few bolts, wiggles it around and it slid together, then tightened all the bolts down.

I will check each of these things you suggested again when I get home from work today.

Thank you!

RE: to my last reply. After reading over some other forum posts maybe MJ in the UK or JimB will chime in, not sure if they?re still around on the forum or not. I will check over the clutch and everything again tonight after work and report back.

Hi, are you sure you have the clutch adjusted properly with the adjustments on the pressure plate. I am told the only way to adjust these dual stage clutches is to remove the flywheel and put it on the bench and attach clutches and pressure plate and do the adjustments and then remove clutch and pressure plate and reassemble on the tractor.
If you leave the Hi/Lo lever in the neutral position does the tractor try to move forward? If you turn the engine off can you put the Hi range into gear? I think the clutch is dragging turning the input shaft or the other option could be that the transmission input shaft is not turning freely inside the PTO drive shaft.
Re REV bogging the tractor, IIRC the 1st & REV gear are the same. Is it not coming all the way out of 1st gear?

JimB thank you for the reply! I have the shop manual, I will have to reread it tomorrow, but I don?t recall the adjustments being that way, I could be completely wrong..

I took a video but I guess I can?t post it, Jacked the rear end up, gears in neutral, high/lo in neutral and the wheels are going like it?s in 4th gear. Press the clutch, doesn?t do anything. Press the brake, tractor will bog until it stalls. If I turn it off and try to go into hi I think it goes, it?s hard to tell as everything is ?tight? as in the gears feel almost brand new and not worn out.

When I had it all torn apart, I put new seals in basically everything cause they were all cracked and fell apart. The new main input shaft seal that goes in the bellhousing was tight on the outer pto shaft when I installed it. I took it out, twice, took the bearings out, twice, and made sure they were free. New seal has to be a C-hair smaller than the old one, but I can?t see that causing me this grief. Only other difference is the new friction plate from agkits.com is maybe 1/8-3/16? wider in surface area than the old one, wouldn?t be a problem as it doesn?t interfere with the flywheel or the clutch housing.

Only ?easy? thing left for me to try is tear the hydro unit off, take the shifter off, confirm the slides are in the correct spot. Or loosen the clutch back off of the flywheel and check the alignment. Once again, I will read over the book again tomorrow.

Thank you for your input, I truly do appreciate it

Hi send me an email at [email protected] and I will email you a pdf document about adjusting the clutches, pressure plate and fingers with flywheel on the bench.

One other thing is that IH made a major change to the transmission and hydraulic systems when they changed from the 5 5/8 inch brakes to the 6 1/2 brakes in early 1964. Check through the parts manual on Messicks.com for both sides of the serial break. I have a 1963 B414 with the 5 5/8 brakes that someone changed the gearshift lever and cover to one from a tractor that had the 6 1/2 brakes. After the changeover I couldn't get the tractor to operate in high range or in certain gears. I asked my local dealer about it and fortunately they remembered the change. He told me I would have to get a cover and gearshift from an early B414 as they were different. We did that and the tractor worked as it should afterward. I did a check of the parts catalog at the time (30 years ago) and remember there are a lot of other changes in the B414 other than just the brake change at that serial break.

This is just a possible cause. Just make sure the parts you put in are identical to the original parts.
