P&H 4100XPB Rebuild with Wearite bushes

ZEMEK Engineering has recently installed new Wearite bushes on a client's P&H4100 Dipper door.

Wearite's demonstrated benefits:

Improved safety

- Dry ice use eliminates liquid nitrogen handling risk.

- Safer handling with less than 3kg Wearite parts vs 20kg OEM metal parts.

Reduced Cost

- Two large bushes fitted under 30 minutes.

- No grease required in operation.

- No line bore required when replacing Wearite bushes.

See the simple installation steps below:

1. Shrink bushes in Dry Ice

2. Check dimensions of bush and bore

3. Slide bush in by hand

4. Wait for bush to expand, Done.
