SHIM ADJUSTING PIVOT BEARING (SET)
King pin bearing shim set
For early closed knuckle front axles
Complete shim set for adjusting the preload on king pin bearings of early closed knuckle front axles. This shim set enables precise adjustment of bearing preload, essential for optimal steering precision and bearing longevity.
|
Application Early closed knuckle front axles |
Function Bearing preload adjustment |
|
Vehicle type Early 4x4 and 6x6 lorries |
Contents Complete shim set, various thicknesses |
Features
- Various thicknesses for precise adjustment
- Suitable for upper and lower king pin bearings
- Essential when overhauling axle knuckles
- Sets rotation preload correctly
- Prevents excessive bearing wear
★ Professional shim set for correct adjustment of king pin bearings. Accurate preload prevents bearings that are too loose or too tight, which is crucial for steering behaviour and service life of front axle components.
Application
Suitable for early model 4x4 and 6x6 military vehicles with closed knuckle front axles where the king pin bearings are adjusted between bearing caps and steering knuckles. Typically one set required per front wheel.
Installation notes
Shim adjustment is performed by combining various thicknesses until the correct rotation preload is achieved. Preload is measured with a pull scale: typically 12-16 lbs pull force for rotating the steering knuckle. Upper and lower shim sets must be equal on early models to keep the axle centred in the inner oil seal. Always consult the technical manual for the correct procedure and specifications.
Compatibility
Exclusively for early closed knuckle front axles. Not suitable for later model axles with ball joint suspension or open knuckle versions. Note: some late production vehicles already had an integrated shim in the lower king pin—check beforehand.
Historical context
King pin bearings were the standard construction for steering knuckles on military vehicles from the 1940s. Shim adjustment enabled precise compensation for manufacturing tolerances and ensured optimal bearing preload under demanding off-road conditions.
