Have any of you replaced the rear main seal in your Perkins engine? If so, I have some questions for you.

My first RMS on this type engine. Retainer, 2 pcs. rope seals and gasket arrive. Repair manual states, in capitals, ..."work the seals into the retainer grooves and leave .010-.020 excess above the surface". I worked those 2 seals into the grooves to the point where I couldn't imagine that they could not be seated in that damn groove. Now, protuding out of the grooves of each half of the retainer are like about 3/16"! I think I have to do some trimming. What do you think?

Yes, you will need to trim leaving 1/8" protruding. We used to soak the seals in engine oil for 24hrs prior, then roll them in using something like ahammer handle, use sealant between the 2 halves and also behind the plates where they bolt to the block and oil pan, tighten the 2 long bolts on sides of housing first.
