the curse

[big hunter]

are there any allis chalmers tractors that don't jump out of 3rd gear. I've seen on here everything from wd's to 200's that jump out of gear...what the heck

 

[bob18]

Yep!! My CA doesn't and it hasn't been treated the nicest!

Neither does my WD-45 even after 50-plus years of abuse.

My father farmed with a WD and a D17 for many years doing everything from tillage to harvesting and never had either of them jump outta gear. I'd never even been aware that the AC's had this problem until I heard it being constantly mentioned and discussed on this forum.

it is more common on some of the D series than the older WD45- CA or B. Some of the guys that "fix" them have commented that the gears have an alignment problem that can be improved with moving the ball detent spots on the shaft. i dont know what percentage have the problem, but there does appear to be a design problem that can be improved with some alignment.

The main reason is raking the transmission into gear. We had to replace third gear and collar on our WD 45, but it was our own fault. It was so much easier to shift between reverse and third without using the foot clutch when manuevering the feed mill around.

My C had that problem a few years back. It was caused by a tired spring washer at the front bearing of the trans main/input shaft. Got a new one from the AC dealer and fixed it.
The spring washer looked simular to the ones that are used behind the bearings in an electric motor.

My Dad started with a couple WDs and WD45 in the 60's and then in the 70's through mid 90's had a D17 and a 190XT and none of them ever jumped out of gear. The WDs and then the D17 were loader tractors besides doing the medium size field work and the D17 still is used for loader work.

My uncles all farmed with AC and the only one that jumped out of gear was one uncle's C and all he fixed was the shift rails.

I used to work at an AC dealer and there were tractors that came in to have that problem fixed. Usually it could be done easily by repairing the shift rails. Sometimes the farmer would let it go too long then you had to tear down and replace collars and gears. If the tractor had a lot of hard hours on it then thrust bearings would be worn and needed to be replaced along with maybe collars and gears.

My dad was an Allis dealer in the 70's. I remember him talking about the gears going out. He said you could tell when the gears were abused vs normal wear and tear. 99% of the gear failures were from operator abuse. My family had owned numerous Allis tractors new and used. We never had problems with the gears.

wd straight stick and wcs the ones with straight cut gears dont

It's never happened on my '52 WD in all the years I've had it.

 

[Will Herring]

Our '48, '52, and '53 WDs don't do it.

My D-19 jumps out of third only when going down hill or over a terrace, pulling is OK

 

[KJFarms]

We have had A/C for years, the only series that had most of those troubles were 185-200, some 210's. Most of the problems are operators to impatient to push the clutch in and shift the gears without grinding. We still have a 185 that was bought in 1974 with nothing done to the transmission. Now our neighbor has had troubles with his 190XT and 200. But no troubles with our WD45, 175, 185, and none of our newer ones either.

 

[Tinker-by-day]

May be a bad bearing on the main shaft or the cluster gear. Since it only jumps out of gear during backlash, the ball detent spring may be too weak.

Three reasons that transmissions gears will not stay meshed: one or more gears have excessive wear and are too narrow; or the two gears are not properly alligned, such as the two shafts are not parallel (loose bearings); or the slide gear is not sliding completely into mesh with the fixed gear.

My D19 jumps out of 2nd when it pulls hard, but I rarely pull it that hard in 2nd. I just use it on a shredder and blade. On a medium load, with your knee against the shift lever, you can feel it jump back into gear when the governor backs the throttle off.

The way I use it, I can live with it. But, I think I'll pull the shifter and check the forks, both for wear and for travel.

My dad has a D17 series II and it jumps out when pulling hard. Also it"s tough to get into 2nd gear.
