1948 Cub clutch adjustment

Postby Dave F. » Mon Oct 04, 2004 8:59 am

My 48 cub needs to have the clutch adjusted, The gears rake as you put it in gear. and the pto won't stop intirely when you press on the clutch. There is no pedal adjustment. Like my 52 cub has. so how do you adjust the clutch. Thanks Dave F.

Dave,

It's difficult to do it accurately with the tractor together and is best to do it by splitting. Having said that, it can be done through the hand hole. The problem is you need one hand for the wrench, one for the stubby screwdriver, and one for the measuring tool. It gets crowded with all 3 hands in there! :lol: :lol: :lol:

The levers should be adjusted so they are 1 1/4" from the plate and all exactly alike. I only did it once through the hand hole, and used a special and expensive tool to measure with... a very small stick with a drywall screw driven through it projecting exactly 1 1/4". I think a different tool would work as well... a stiff wire bent sharply to 90 degrees, and with one side trimmed to exact length.

The lever you are working on should be on the bottom and marked in some way so you are sure you get all 3. It would be easy to miss one when turning the engine.

Naturally, when you are finished you will want to adjust the pedal for free travel. On the '48, the pedal adjustment is on the rod on the inside, rather than on the pedal externally. You'll have to pull a pin on the yoke to adjust the length of the rod. :( :( :(

George, would I need to make the rod longer or shorter? I would think longer? I think my clutch adjustment is ok. I don't feel bouncing or vibration in the pedal. Thanks Dave F.

Dave,

I expect the rod needs to be lengthened. If you have a parts manual, you can refer to page 3 of section 7 and note the relation of #8 to #9. Also, make sure the bolt holding #10 and #11 together is tight.

This is not a fun plce to work! :lol: :shock:

"I only did it once through the hand hole, and used a special and expensive tool to measure with... a very small stick with a drywall screw driven through it" I swaneee. Someone else has taken up some of the verbage I've had to use with working on gov't 'puters. I've used $15,000 tools to open stuck CD-ROM drives with. Only they were called paper clips. Good one George! Once again, you have my respect. You too, Big Dog.
