Rear main seal, finally done…flywheel too
Some of you may know about the dilemma of my rear main seal. Â Just look at the pictures of it below (few posts down). Â It was nasty! Â The outside was sprayed with orange sealant; and when I removed it last week with the carrier, the inside was filled with grease. Â Grease? Â Some fellow s14’ers said to leave it alone, others to change it. Â The RMS is a recurring issue for many; and if not changed correctly, a persistent leak occurs. Â
I chose to replace it-along with everything else.  I bought a new RMS carrier, bolts,  and dowels.  Throwing the baby out with the bath water!  I basically got all the new parts listed here (except for the paper gasket, I used a hi temp gastket maker instead).
Ok, here’s what it looked like before I started.
Â
The new parts (excluding bolts and dowels):
Â
To press in the seal, I used two pieces of plywood and a rubber mallet. Â This method got it perfectly flush with the new carrier. Â Since this is a replacement seal, it must be pressed in an additional 1-2mm in order to sit on “fresh” steel. Â I used a metal ring to tap the seal 1mm from the carrier edge.
Â
Â
Now, the next issue was removing my pilot bearing.  It was kind of frozen.  A shot of PB Blaster didn’t work too well.  The good ole’ toilet paper method was needed.  First, get a wad of TP; second, wet  and roll pieces small enought to get into the bearing hole; third, repeat #2 until the cavity is full; fourth, get something that will will fit nice and snug into the bearing hole (for me, a 3/8″ 4″ extension worked nicely) and give it some moderately sharp blows; fifth, remove tool, repack, repeat #4; sixth, eventually the bearing will slide out due to the displacement of the tool in the bearing cavity.
Â
Finally, I can replace my newly lightened and resurfaced flywheel. Â I used blue locker/sealant and also a dab of silicone gasket maker to minimize the possibility of oil leaking through the bolts.
Â
Phew, that’s over! Â Now time to install the clutch and tranny. Â 🙂
