WESPC CH11686 bush replacement is a precision-engineered transmission support component specifically designed for Perkins engines, providing reliable performance and extended service life.

Specifically designed for Perkins 400 Series (403D-15, 404D-22) and 1000 Series (103-15, 104-22) engines.

• Compact construction machinery: micro excavators, walk-behind rollers
• Agricultural equipment: tea pruning machines, small seeders
• Portable generator sets: 10-30kVA range
• Industrial auxiliary equipment: small diesel water pumps, air compressors

Provides stable support for crankshaft rotation up to 4000 r/min while limiting radial runout to within 0.05mm, ensuring smooth engine operation.

Features low-friction properties with sliding friction coefficient below 0.07, significantly reducing energy losses compared to direct metal-to-metal contact.

Works in conjunction with oil seals to create dual protection against dust, moisture, and contaminants in demanding outdoor environments.

Evenly distributes radial pressure during operation to prevent localized stress concentration, reducing maintenance frequency and extending service life.
