Oil Seepage at Flywheel Housing

FSB 212-002, Oil Seepage at Flywheel Housing
VN, VHD, VAH

(April 2012)
Aftermarket has requested a solution to solve leaking flywheel housings. There is an area
near the PTO where the sealing between the flywheel housing and the timing gear plate
needs improvement. This problem has already been solved in production, but the production
solution is not compatible with previous generation flywheel housings.
A bracket has been created to reinforce the timing gear plate in this area. This reinforcement
increases the contact pressure in this area above the current production solution and will
eliminate the leaks. A kit has been created to solve each of the potential aftermarket
scenarios.
