7W3202 Seal Gp-Crankshaft — Cat 916 926

Name: 7W3202 Seal Gp-Crankshaft — Cat 916 926
Brand: CAT
SKU: 7W3202
Availability: InStock

This crankshaft seal group is designed to prevent oil from leaking out of the engine around the crankshaft's rear main bearing. Manufactured to strict standards, it ensures effective sealing and maintains proper oil levels for engine lubrication, unlike a worn or damaged seal that allows oil to escape. Operators may notice oil drips under the engine, a burning oil smell, or a significant drop in oil level when this seal begins to fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

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

Failure Symptoms

The first sign of a failing crankshaft seal is typically visible oil leakage at the rear of the engine, often noticed on the garage floor. If left unaddressed, the oil loss can become significant, leading to low oil pressure and potential lubrication failure for critical engine components. Continued operation with a leaking seal risks severe engine damage due to inadequate lubrication.

Installation Tip

Carefully inspect the crankshaft surface for any nicks or damage before installing the new seal, as imperfections can cause immediate leaks. Ensure the seal is installed perfectly square to prevent binding or premature wear.

Service Note

Inspect the rear main bearing and crankshaft for wear or damage when replacing the crankshaft seal group.
