A large number of shops have the 9699 RMS seal tool (bell) but many do not have the newest insert 9699/2 for the low tension PTFE RMS:
- The new 9699 tool installs the RMS straight without thinking.
- The new 9699/2 tool insert installs the RMS deeper into the engine case.
1. Clean the complete engine bell housing area (preferably with Winzer MPS, solvent). Additionally, clean any Loctite or other thread locking compound out of the crankshaft flywheel bolt threads.
2. Replace the four (4) crankcase Torx bolts (6mm x 35mm) part number 999.385.004.01 in the bell housing area. These bolts are microencapsulated with thread locking compounds. Torque each bolt to 114” In/lbs.
3. Center punch the existing RMS in one of the dimples or in the center of the RMS.
4. At the center punch location, drill a 2mm (5/64”) hole through the seal. Be careful of the drill depth once the bit has penetrated the seal material. We recommend utilizing a spacer (or socket) on the drill bit to limit drill bit penetration depth.
5. Install a sheet metal screw, size #8 x 1” firmly into the hole in the RMS. Attach a slide hammer to the head of the #8 screw; operating the slide hammer mildly, the old RMS should come out without struggle.
6. Clean the crankshaft and engine case bore thoroughly. Inspect crankcase and crankshaft for any scratches or burs. Inspect crankshaft for any RMS caused wear.
7. Utilizing the factory tool number 9699/1 (PN 000.721.969.91) “Go-No Go” gauge tool, check for a proper crankshaft to crankcase relation (center position). Only proceed if the test is successful, if not, additional repairs or replacement of the engine is required for a non-leaking RMS. Otherwise notification to the client will suffice, this is all in the interest of CYA.
8. Install the new low tension PTFE RMS, part number 997.101.212.01 with factory special installation tool 9699 utilizing insert guide 9699/2. The new RMS comes mounted on a plastic sleeve (for transport Purposes) that mounts onto the insert guide of the RMS tool: the dimples in the RMS will be facing away from the crankcase (towards the RMS tool). The 19 mm bolt on the 9699 mounting bell RMS tool must be rotated clockwise until it stops to achieve the proper RMS installed depth.
Replacing the M96/M97 RMS
If the RMS is installed flush with the Crankcase (incorrect), it is highly likely that the RMS will work its way out, as illustrated in these two photos:
Please note: These RMS seal old PN’s have been superseded, 999.113.476.40 & 999.113.490.40.
9. Always replace the flywheel bolts part number 999.073.092.09 or Tiptronic flex plate mounting bolts, part number 999.073.091.09. These bolts are considered “torque to yield” (TTY) fasteners. When a regular bolt is tightened it stretches or gets longer as more force is applied.
If tightened to a point less than its threshold of yield and the load on the fastener is released, the fastener will return to its original length. This is known as “Elastic deformation”; the bolt stretches under load but will return to its original length and is reusable. Whenever using a TTY bolt, this is not the case as the bolt is intended to deform. The bolt is tightened to an initial torque setting, and then in a second pass is tightened by a torque angle (a measured distance in degrees) which stretches the bolt beyond its ability to return to the original length, this is known as “Plastic Deformation”. The advantage of utilizing TTY fasteners is that a more even attachment can be achieved, if all the bolts are more evenly loaded.
10. Utilizing a new Q-tip, apply a very small amount of blue Loctite #242 no less than 8mm (8 threads~) inside the depth of the flywheel bolt threads on the crankshaft. Do not allow the Loctite to get on the flywheel mating area of the crankshaft.
11. Place the Flywheel or Flex Plate in position and insert bolts.
Torque the flywheel or flex plate bolts in a star pattern to 19 Ft/lbs. for the initial setting, then turn each bolt an additional 120 degrees to the final setting.
