CATBearing & Bushing

7K9644 Bearing — Cat 988

This is a heavy-duty bearing designed to reduce friction and support rotational loads within the power train or undercarriage systems. It is manufactured to meet stringent CAT material and dimensional standards, ensuring superior durability compared to a worn or damaged bearing. Operators may notice increased noise, vibration, or a noticeable decrease in component performance when this bearing begins to fail.

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

Initial signs of failure may include a grinding noise during operation or increased heat generation from the affected component. If left unaddressed, the bearing can seize, leading to component seizure and potential damage to surrounding parts. This can result in unexpected downtime and costly repairs.

Installation Tip

Ensure the bearing housing is thoroughly cleaned of all old grease and debris before installation. Avoid using excessive force or improper tools when pressing the bearing into its seat, as this can damage the raceways.

Service Note

Inspect adjacent seals, shafts, and housing bores for wear or damage during bearing replacement.
