Part Number: 816/20049
Applications:
The Grease Fitting Adapter is a reducer component in the boom section of JCB 3CX and 4CX backhoe loaders. It adjusts oil flow or force transmission between boom segments, enabling smooth and precise arm operation.
Function in the Machine and Failure Diagnostics:
Ensures proper operation of the boom cylinder and controlled arm movement.
Role of the part in the machine:
Ensures proper operation of the boom cylinder and control of boom arm movement.
Consequences of failure or leakage of the grease fitting adapter:
Uneven movement of the boom arm
Loss of lifting power
Hydraulic oil leaks
Additional note:
If your grease nipple is broken, corroded, its ball is stuck, or it is clogged with dirt, proper lubrication becomes impossible. Ignoring this issue results in “dry operation,” which quickly leads to seizure and damage of pins and bushings, generating very high repair costs.
