4V7079 Universal Joint Gp — Cat 814B 814F

This is a Universal Joint Group designed to transmit rotational power between shafts that are not perfectly aligned, typically found in the driveline of heavy machinery. Manufactured to high standards, it offers robust performance and longevity, outperforming worn joints that exhibit excessive play or binding. Operators may observe vibrations, clunking noises during acceleration or deceleration, or a loss of power transfer when this component is failing.

Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early indications of a failing universal joint include a clunking sound when shifting into gear or changing direction, and noticeable vibration through the operator's station. As wear progresses, the vibrations will become more severe, and a loss of driving power may be experienced. Continued operation risks driveline damage and potential loss of mobility.

Installation Tip

Before installing, ensure the mating yoke splines are clean and properly lubricated to prevent galling. Avoid over-tightening the U-joint straps or bolts, as this can distort the bearing caps and lead to premature failure.

Service Note

Inspect the driveshaft U-joint bearings, center support bearings, and companion flange for wear or damage.
