Recent thread reminded me of this job and I've been sitting on a pretty neat CAD design for a tool to help facilitate installing the front main seal into the S54, so I thought I'd share to help someone make this painful job a little less painful.
This tool can be printed from PLA/ABS/PETG or whatever material you have, and helps install the seal to the correct depth without damaging the seal. It is adjustable so that your new seal does not line up with an existing groove on your crank sprocket. I recommend printing at or near 100% infill.
Instructions:
1. Clean the taper adapter and crank with alcohol to ensure they are free of oils. Do not use acetone or any aggressive chemicals.
2. Install the new seal onto the taper adapter until it starts to stretch and stays in place.
3. Install the taper adapter with seal onto the end of the crank and attach it using 2 of the stock crank bolts. Lightly snug them down and ensure the adapter is centered on the crank so there is a nice transition.
4. Select the desired seal depth on the press cup. Position 1 corresponds to an almost flush install and Position 4 will position it towards the back of the timing cover. Position 2 or 3 is most likely used. Change position by sliding the inside part out and aligning it with the slots. You may want to incrementally press it in until it’s at the desired depth.
5. Put the press cup over the seal and slowly tighten it down with the center bolt. Ensure the seal is going in straight. A thin layer of grease on the OUTSIDE of the seal can help it slide into the timing cover more smoothly.
Additional Parts Needed:
1. OEM vibration damper bolts
2. Long bolt, nut, and BIG washer from hardware store (Size M8). Get a big thick washer to help distribute the load.
3. Front Main Seal
