522-2830 12.7mm camshaft ball CAT wheel loader spare part

Advantages

• Designed to withstand the high pressure and temperature in an engine’s valve train.
• Manufactured with steel which is high strength and ductile.

1. Tight dimensional tolerance, reliable sealing after pressing, not easy to loosen and leak oil
2. High hardness bearing steel, resistant to deformation under continuous oil pressure impact
3. Smooth spherical surface, uniform pressing force, less risk of scratching camshaft bore
4. Compact size, replace during camshaft oil passage inspection to prevent hidden oil leakage

FAQ 

Q1：What will happen if 522-2830 ball loosens and leaks oil?
A：Oil bypass occurs, insufficient lubrication for camshaft and bearings, leading to rapid wear and bearing seizure.
Q2：Is there a standard pressing depth for the ball?
A：Press to specified recess depth. Too shallow will cause pop-out; too deep will block oil passage.
Q3：Can removed old ball be reused?
A：Not recommended. The spherical surface has compression deformation after pressing, sealing failure risk is high.
Q4：Will new ball seal well if the bore is worn?
A：No. Worn bore cannot be sealed only by new ball, repair or replace camshaft.
