Either should be fine providing the old one is still good. And that the new one is not so thin that it makes linkage and other parts not have correct clearance

Thank you sir. Would you know of a diagram that would show all the grease fittings on a 100? Would really like to get this all lubed up while I have a chance.
Thanks Dave

In the tech section here you will find the manuals for the 100.

Heres a lonk to the chassis service manual

And heres the operators manual

Thanks for the heads up on the manuals. Should help a lot. Thanks Dave

If the original gasket is still in good shape ( good surfaces on both sides), it should be acceptable to reuse

I know that my Quietlines use the thicker thermal isolation gasket (part # 47-049-01) to help reduce heat transfer to the incoming fuel. Wouldn't think it would be a problem to use it on your tractor. If you're concerned about it sealing properly, you could put a THIN film of some sealant on the mating surfaces. Like this Permatex Anaerobic Gasket Maker;

Remember, air leaks at the carb can draw dirt into the engine, promoting premature engine wear.

Well, here's another question to throw out there. As i'm looking over this 100, I am wondering, are the tie rod ends the same as the ends on the steering arm that connects to the front end. Are these end prone to needing replaced after all these years? Thanks

Just wanted to update the progress on my 100. Thanks to all for your help and especially Bill Cooper (Cooperino). As of today the 100 starts and runs. Now that I have the "go" I'm needing work on the "whoa". Brakes all but non existent. But again I wanted to say thanks to all for your help and encouragement.
Any suggestions on the on the brakes would be great. As I depress the clutch/brake pedal the brake lever hardly moves.
Thats it for now.

There is a procedure to adjusting the brakes in the manual, pretty easy, unless something is broke or worn out it should take 5 minutes.

Will give that a try. Thanks
