BMW Driveshaft to transmission output flange fitting, all Airhead models
BMW Driveshaft to transmission output flange fitting, all Airhead models:
The correct part number for bolts for all models is: 26 11 1 242 297
NOTE: Do NOT use a lock washer, even if yours came with one. Use only the bolts above. A drop of blue Loctite on each is a good idea. You need 4 bolts, and these should ALWAYS be replaced with new ones. Never reuse a bolt. These are designed to stretch a specific amount at the correct torque, and cannot be re-used (except in an emergency of course, but that's your decision!)
The correct tightening torque is WITH the BMW special adapter according to Haynes BMW Twins 1970-1988:
"NOTE: On all models the torque setting is specified to take into account the leverage which results from the use of the special crowsfoot type spanner BMW Tool 00.2.560; do NOT attempt to approximate it using any other means (such as applying a measured pull at the end of a spanner of known length). Use ONLY the BMW tool to tighten the bolts; if necessary take the machine to a BMW dealer..."
