I don't have a manual yet for my Cub. I push in the clutch but gears grind when trying to put transmission into gear. Is there a way to adjust free travel on the clutch? It has about 2". Also, when I push down on the clutch it seems to load the engine. If idle is very low, it will stall engine by pushing down clutch. Any ideas what is causing this????? Thanks in advance for any help you can offer. You guys here are GREAT!

Thanks for all your help guys. I did find the problem - throw-out bearing siezed up. I guess I will be splitting the tractor soon.

Well...I'm learning something too...I greased the grease fitting on the cluth on my 52...I assumed they wouldn't put a fitting on ther if it wasn't supposed to be greased. I have essentially the same problem. It doesn't do it if you idle the engine down and wait for 15 seconds or so and it doen't grind. My Cub is currently still pulling mowing duty, but with fall on the way, I'm going to haul it back to the house and continue to fix her up...

It sounds like the throwout bearing is crying for grease! You should be able to find a grease fitting though an access hole in the clutch housing.

Guess I was wrong about the grease. Apparently the clutch bearings on the cub do not have grease fittings like on the larger Farmalls.

Oh yeah, don't grease it too much, a couple or three strokes should be enough.

best thing is split the tractor then you will know the pilot shaft can be dry bearing in the crank bad or dry pressure plate can be rusty on and on tear it down then you can see the problem

on the bottom of the bell-housing there is a round plate take it of and look up in there, the throw out berring does not take grease it is made out of a special material.you can ujst the free play threw that hole in the bottom,it is hard but can be done.also the figers on the presure plate may be ajusted but you will have to split tractor to do that and use a dial indicator to set them all the same.wen you look in the tunnel towards the transmision there is a arm back there with the nut on the back side some times it will come lose and have to be tightened up ,but to do that you will have to split the tractor,if you do split the tractor you must put a block between the radiator and the axel ,one on each side to keep the motor from floping over,take you time

I agree with Gene. If you do not split it now you will be spliting it later. A dry pilot hole in the crank can set up a vibration that will cause the driveshaft to break near the transmission. This happened to me about 40 years ago on my '48 Cub. Don't have a parts book but I seem to recall that there is no bearing. It is just steel against steel and no way to lubricate it short of taking it out. I am much more prudent in the way I use the clutch (or any vehicle clutch) since that experience.
