Description
Overview:
Cover Fixing Studs for Crankcase / Governor are replacement steel fasteners used to secure the crankcase and governor covers on JAP stationary engines. This is a Genuine Villiers Part with MPN 6933, made to the correct specification for a reliable fit and consistent clamping. The studs help maintain cover alignment and gasket seal, resisting vibration and thermal cycling that can loosen inferior fixings. They are suitable for routine service work, repairs, and full engine rebuilds on classic machinery using JAP power units, including JAP 3 and JAP 4 models. If existing studs are worn, stretched, or corroded, fitting new 6933 studs restores correct cover retention and helps prevent oil leaks and ingress of dirt, supporting smooth and long-lasting engine operation.
Key Features:
- Genuine Villiers 6933 fixing studs for JAP engines
- Steel construction for dependable strength under repeated torque cycles
- Correct thread form and length profile for crankcase and governor cover locations
- Helps maintain gasket compression and cover alignment to reduce oil seepage
- Stable under vibration and heat for consistent clamping load
- Direct replacement for tired or missing original studs, no modifications required
- Suitable for workshop rebuilds and in-field maintenance
- Supports accurate cover refit to protect internal components
Typical Applications:
Used during service or overhaul of JAP engines to replace damaged, seized, or corroded cover studs; to ensure secure refitting after gasket changes; and to stabilise crankcase and governor covers on vintage equipment such as pumps, generators, compact construction machinery, and garden or agricultural machines powered by JAP engines.
