Hi all,

I am working on putting an original HiPo 289 back together.  I have replaced the pilot bushing with the oil impregnated FoMoCo version "COMPO".  What is the popular opinion on whether to grease the bushing and crank cavity behind the bushing or leave dry?  I have always greased but am now reading not to.  Thoughts?

(I did a search on the forum and found no prior related thread.)

Thanks

Cory

From memory (which is fast fading! Roll Eyes), I believe the shop manual said to just soak in motor oil overnight.

They should be made of oil impregnated bronze.  If you add grease, it will probably not stay where you want it due to the oil seeping out of the bronze.  The last thing you want is grease contaminating your new clutch.  I'm sure someone makes one with needle bearings in the aftermarket.

^^^^^^^

yes, just soak in oil, and dry off the excess.  No grease needed. 

They will squeak when worn out, & that prompts some people to use the needle bearing. But it takes decades to wear out the bushing.

I've tried it both ways, and am now leaning to the original bushing.
