346-9382-3469382 Wiper Seal 346 9382 — Cat C15 C32

This wiper seal is a critical sealing component designed to prevent contaminants from entering the engine or hydraulic system while retaining essential lubricants. It is manufactured from durable, high-resistance materials to maintain a tight seal under demanding operating conditions, outperforming a cracked or worn seal. Operators may observe oil leaks around the sealed component, increased wear on moving parts, or contamination of internal fluids as signs of a failing wiper seal.

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 wiper seal is typically visible oil leakage from the component it is sealing. If left unaddressed, this leakage can worsen, leading to a loss of lubricant and potential contamination of internal systems. Continued operation with a compromised seal risks accelerated wear on critical components and potential system failure due to insufficient lubrication or contamination.

Installation Tip

Ensure the sealing surface is perfectly clean and free of any nicks or scratches before installing the new seal. Lubricate the seal lip with appropriate fluid before insertion to prevent damage.

Service Note

Inspect the shaft or bore surface for scoring or damage when replacing the wiper seal, as this can affect the new seal's performance.
