description

The 103-9272 lifter sits in the lifter bore of cylinder head. It contacts the pushrod on top and follows cam lobe on bottom, converting cam rotation into linear motion. It is a critical valve train component for Cat C3.4 engines. This engine is widely used on mini excavators, skid steer loaders, motor graders and small dozers with frequent start-stop cycles and dusty environment. Wear, pitting or seizure on lifter base will cause valve noise, power loss and rough idle, and may lead to bent pushrod or broken valve in severe cases.

FAQ 

1. Can the lifter be reused with light pitting on base?
Shallow isolated pits can be monitored temporarily. Replace it if pitting spreads, spalling or scoring occurs, to protect camshaft.

2. Does 103-9272 fit C3.3 engine?
No. It differs in length, base diameter and lift profile. Confirm engine nameplate before ordering.

3. What causes lifter stuck in bore?
It is usually caused by contaminated oil, high operating temperature or out-of-round lifter bore. Do not hammer it forcefully.

4. How many lifters are needed for one C3.4 engine?
C3.4 is 4-cylinder with 2 valves per cylinder, total 8 lifters. Full set replacement is recommended for overhaul.
