Here's a minor mystery that someone may be able to clarify:
Is there an O-ring for the bearing cage assembly on a '87 Force 125 "B' model?
There is no reference to it in the Clymer or Seloc manuals, and I don't see it in the Crankshaft and Piston Parts diagram on Crowley Marine's site.
Both the upper and lower bearing seals where included in the Power Head gasket kit I ordered but there was no O-ring, so I didn't even think of it until I was reading through the Mercury manual for this motor.
I'm thinking this may be a bad reference in the Mercury manual, but I just want to be sure I'm not missing anything.
It is mentioned in the following section (in red) regarding the crankshaft bearing cage assembly:
Power Head Reassembly.
1. Reassemble and install upper crankshaft bearing cage.
2. Clean gasket surfaces on bearing cage and power head.
3. Position crankshaft bearing seal with garter spring on bore of crankshaft bearing cage (major sealing lip in). Figure 52.
4. Press seal in bore of bearing cage using seal installer, Special Tool No. T 8903.
5. Install new bearing cage seal (O-ring) on bearing cage assembly.
6. Install seal protector on top of crankshaft. Special Tool No. T 8927. Apply grease to lips of crankshaft seal. Special Tool No. T 2961.
