Re: Pilot bearing removal?

I have a 2.8V6 engine that I am preparing to install this weekend and have come up against a small problem.  The pilot bearing on this engine is damaged so I want to replace it, I have the new one ready to go in, but I can't get the old one out.  I don't dare try heating it as I think it may affect the temper of the crank or ruin the rear seal.  My only other experience in replacing pilot bearings is with my Spitfire and the old one just came right out with no hastles.  Any suggestions?

Pack the bearing in heavy grease, filling the hole completely. Find a
bolt that is a close fit in the hole and whack it with a hammer. The
bearing should pop out.

Re: Pilot bearing removal?

The way to do this is with a slide hammer.  Sometimes you can find a tool for this, but I made my own.  Usually on a slide hammer, there is a threaded end for attaching whatever.  Use a bolt and nut combo, whatever it takes to have a shaft on the end.  Then take a grinder and put a notch in the end of it so that there is a lip that slides behind the bearing and then just tap the slide hammer.  Work it around and it will come out.  By the way, I don't know if I responded to your last post.  The plugs had been out about 6 months, but still inside my shop all the time.

Re: Pilot bearing removal?

To supplant the other reply, about 'filling' it with grease,
that is correct. Tamp it in all the recesses that you could envision
being behind the bearing. When you insert a close-fitting bolt or
cylinder of some sort, it is the hydrostatic shock that will push the
bearing out, from behind... give it a good, rapid blow with a
hammer,
if you take it easy, the grease will escape around the round object
you have chosen for the task, and nothing will happen...
