Frequently Asked Questions
FTC5303 seals the interface where the primary pinion shaft exits the front cover / clutch sleeve housing on LT77 and R380 five-speed gearboxes, preventing gearbox oil from escaping. Common failure modes are lip wear, hardening or cuts that lead to weeping or visible leaks; inspect the seal during gearbox servicing and replace if damaged or leaking. When fitting, ensure the housing and shaft sealing surface are clean and free of nicks.
