Pilot Bearing Removal Procedure question

300TD w/old style 240 4-speed manual.

I searched on pilot bearing and all I got were people suggesting it should be replaced. Nothing on where it is and very little on how to get it out and back in.

First of all, where is it? Behind the flywheel?
Do I need to remove the flywheel to get at it?
Can I use a slide hammer and hook to get it out?

What about reinstalling? big socket and a hammer?

Thanks!!
Dan

Pilot Bearing Removal Procedure question

1981 300TD w/old style 240 4-speed manual

I searched on pilot bearing and found very little about where it is, how to get it out and how to get a new on back in.

So,
1. Where is it? behind the flywheel?
2. will a slide hammer and a hook get it out?
3. Will a big socket and a hammer get a new one in?

Please advise. Thanks!

Yes, behind the flywheel in the crankshaft.

No, but it helps.

Yes, another method is using grease, a rod and hammer to hydraulically push it out.

Yes, only hit it on the outer race, hitting the center race will damage it.

There are also inside pullers that put fingers inside it and you can then pull it with a slide hammer or a screw type puller. They usually are not too hard to get out.

The pilot bearing is accessible through the large center hole in the flywheel.

Highly recommend a pilot bearing puller. I got mine for about $20 incl shipping. The effort was minimal with it. BTW You might have a pilot bearing cover that would be removed first or together with the bearing.

When reinstalling I have lightly greased the inside well to allow the metal to slide. Without grease the bearing would not go.

BTW To reinstall it I bought a special tool from Home Depot - a wooden post head type of thingy. Got two - one wide one narrow. This way I knew I was not damaging the bearing.

BTW It's a great idea to replace it! $5 part - if it goes bad you'd have to repeat the entire clutch job.

There is spoz to be a little "cuped", steel keeper that fits in after the pilot bearing with a hole in the middle where the trans input shaft goes through. I have found that omitted on occasion when pulling MB trannys.

Grease and a rod

Just get a nice fitting steel rod that just fits. Pack your choice
of grease in the hole. Smack with a hammer. Out it pops.
