WD45 questions

We have gone completly thru a 1954 WD45 and getting ready to put the motor back in I noticed the end of the transmission shaft that fits into the crankshaft that has a pilot bearing is very rough. Is it supposed to be that way and does it have a pilot bearing or not. I don't know if something happened to it at the machine shop or not. Also is there supposed to be a bearing in the fly wheel that the transmission shaft rides on or does the throwout bearing carry everything. It's 60 miles to the dealer and hope someone might have some answers before I head that way. The operators manual is not clear on this. Also, is it still possible to get a new clutch and right brake pedal? Mine has wore egg shaped in the hole that the shaft goes thru, or is it possible to bore it and sleeve it? Thanks for any answers. Harold

You are likely to be just as well off getting the clutch and brake pedals bored and sleeved at a local machine shop. The transmission shaft should not be rough- the splines should be smooth and fit into the clutch assembly that bolts onto the flywheel. There is no extra bearing.

You can bore the pedals out and have sleeves made for them.I had mine done.You might want to have a new shaft made for them too.That will tighten them up like new.Real easy for a machine shop.

JMS/MN The splines are smooth but just the last inch what I think should go into a pilot bearing is rough. If that should be smooth can you just smooth it up with hardware cloth? Thanks for your help. Harold

I've never seen any transmission input shaft that didn't ride in a bearing or bushing in the end of the crankshaft to keep the shaft in alignment when the clutch is depressed. My WD has a bronze bushing which is the most common. I assume the WD-45 has the same. Is there a bushing in the end of your crank? In most cases it is advisable to replace the pilot bushing when either the engine or transmission is removed. When the clutch is engaged, the input shaft and clutch disc turn together so there is no need for a bushing then. However, when the clutch is released, the input shaft stops and the crankshaft continues to turn; hence the need for the bushing/bearing. So..... .yes the end of the input shaft should be smooth. If it's not too bad it can be cleaned up with crocus cloth. Keeping the clutch pedal depressed for long periods while the engine is running will cause undue wear to both the release (throw-out) bearing as well as the pilot bushing.

Brian, I just checked the end of the crankshaft and it looks like there is a place bored out about the size of a silver dollar and then it starts about the size of a nickle and then is bored in at about 45' angle down to the size of a pencil and then it's a hole on in to the crank. There is no way to get a bushing in there. I've never seen anything like it.It must run with out a pilot bushing. Hope you can follow what I've tried to say. Thanks for your comments. Harold

Curiosity got the best of me and I began studying the A-C manual; the best tool in the shop! It is true, you're never too old to learn something new!! WD tractors after "engine" Ser.#WD310920 up to and including WD-45 tractors with "engine" Ser.# 45-30955 were not equipped with a pilot bearing. Hard to believe!! Anyway, an oilite bronze pilot bearing was used on the WD-45s beginning with "engine" #45-30956. The manual recommends installing a pilot bearing on those tractors without one. A spacer kit comes with the bearing. This kit contains 3 spacers and you are to use the one that gives the best fit between the end of the input shaft and the bearing. This is necessary as the shaft end was not held to a close tolerance during manufacture because they hadn't planned on using a pilot bearing. That is probably the reason the end is so "ruff". I would guess Sandy Lake or your local Agco supplier can provide the bearing and spacer kit. When you're finished, your tractor will literally be better than new; in this aspect anyway.

I finally got it figured out what I need for a bearing. And as soon as it comes, I'll be able to get her back together. Thanks for all the help and answers to my questions. Harold
