587 cc 1993 GTX Crankshaft Oil Seal "Lip Cavity"

[SurfBeat]

Based upon a previous post it appears I did not make my question clea, thus I am treading in waters without a good chart.

It's time to install the crankshaft in the bottom case and seal things up, however, before doing so I read in my Clymer's Manual to "Fill both of the outer crankshaft oil seal lip cavities with synthetic grease.

Unfortunately for me, Clymer's does not have a diagram showing what the hell they are referring to (oil seal lip cavities) and my SD shop manual does not make it clear either. In fact, my SD shop manual contradicts Clymer's by stating to "apply lithium grease on the lip" of the seal in contrast to applying synthetic grease as related in Clymer's.

I am not a mechanic, but continually learning how to do work on my Doo the right way, so, on that thought I don't what/where the lip of a seal is and what is meant by a "cavity" in the seal? Both instructions has me totally baffled!

When tinkering with the crank and looking at the diagrams in my manuals, it appears that the "oil seals" (1/2" black color, circular plastic/rubber parts facing the bearings) simply slide off the crankshaft?

Upon removing the two outer seals I noticed that the side facing the bearing is concave, thus, I am presuming Clymer's is inferring that the "cavity" is the concave side of the seal, thus I am to completely fill up the entire cavity (about 1/16" deep, full diameter of seal) with synthetic grease?

Although that appears to be the most obvious, I pondered, is the lip the inner edge of the hole in the seal, i.e., as the inner circle in a doughnut.

I apologize for being so literal, however, I want to do this project right.

It would appear that the crankshaft shop that sold me the crank would have filled the cavity so as to avoid this crap! Had that done so it would have made my project simpler.

I want to get this engine installed this weekend so I can get it in the River on the 5th ,when everyone leaves.

Thanks

Help....

Help... Here's my first advice, ..... Toss the Clymers out the window. I use Clymers and have several, but they are for my car and tractor engines. Clymer is not in the PWC/jet boat business. If you'd like to use them both, and you come across a contradiction, the BRP should always be the default.

Use the lithium. This is the grease all mechanics choose when putting an engine together.

Some seals are designed differently and after the time frame from when this engine was built and the superceeded parts you may be getting now, the seals could have changed.

In most cases, what they are describing is simple. The seal top and bottom. The part of the seal that faces outward is usually smooth. The inner side usually has a lip or groove where most times, you can see a small spring. This is where they are asking you to put in a dab of grease.

Dump the Clymers... it'll help you avoid a bunch of extra crap that you dont' need to go through.......

In response to your recommendation that I use lithium grease rather than synthetic, can I use the same lithium grease that I use for the grease fitting on the wheels of my Doo trailer that contains Molly, or must I only use lithium?
