Product Name：camshaft bearing

Height (in): 2.6
Length (in): 7.8

Outer Diameter: 184.10 mm

Application Scenarios

Fit for Caterpillar matched engines. Suitable for construction machinery and heavy equipment working under long‑time heavy load in mines. Used to replace worn, scored and alloy‑layer‑peeled old camshaft bearings.

Maintenance & Replacement Tips

Fully disassemble the engine, clean oil passages, grease and metal debris of bearing housing bore, check housing bore for deformation and damage.
Confirm bearing orientation and align oil hole with cylinder head oil passage before installation. Blocked oil passage due to misaligned oil hole is not allowed.
Press in steadily with professional pressing tool. Hammering or forced fitting is forbidden to avoid bearing deformation and alloy layer cracking.
Recheck outer diameter after pressing and confirm clearance is qualified. Rotate camshaft by hand after assembly, it should turn smoothly without jamming.
Do not reuse bearing with scoring, alloy peeling or excessive clearance; replace the whole set directly.

FAQ 

Q: Can I replace only one damaged bearing shell?
A: It is recommended to replace the whole set of camshaft bearings during overhaul. New and old bearings have different wear rates, which may cause uneven clearance and re‑scuffing.

Q: Why is the camshaft tight to rotate after bearing pressing?
A: Check bearing deformation after pressing, misaligned oil hole, housing bore deformation or wall thickness tolerance deviation of bearing.
