Post by: Mr.Pontiac on August 24, 2022, 06:58:36 AM

They are "interference" fit so go in with some effort.  Never had any issues getting them in. 

Take a pocket knife and chamfer the lower edge a little more.  On the ones I sell I've already removed the sharp edge and chamfered them a bit, but sometimes they need a little more help.....

Out of curiosity I went out to the shop and installed one of
Cliffs PP retainers in a 17084226 casting that was laying around.
As usual it's tight but it fits.
There is a step at the top of the bore where the retainer fits
that is 0.392 inch. Check that the stepped area is not occupied
with part of the old retainer.  ...????
