F30A & F31A MANUAL TRANSAXLE OIL LEAKS
APPLIED MODELS: 1987-1990 Sentra (B12) 1987-1990 Pulsar NX (N13)
SERVICE INFORMATION
The F30A/F31A manual transaxles used on the Applied Models listed above (check the appropriate model Service Manual for manual transaxle application) may exhibit transmission oil leakage between the clutch housing and the transaxle case due to insufficient case bolt torque.
PARTS/TORQUE INFORMATION:
To improve the sealing performance at this area, a higher grade bolt is now used in production, and the housing bolt tightening torque has been increased.
If transmission oil leakage is observed at the indicated area, or if transaxle service is required, upon disassembly of the transaxle case halves, thoroughly clean and inspect the mating surfaces for porosities, surface damage, etc. Apply sealant to the mating surfaces, then install the new bolts, being certain to apply additional sealant to the appropriate bolts (see Service Manual). Torque as indicated below.
After assembly has been completed, test drive the vehicle, then inspect the indicated area to ensure a proper seal between the mating halves.
