description

This is genuine Cat Reman camshaft for C9.3 Tier4 electronic engine. It is rebuilt from qualified core shaft through crack inspection, journal regrinding, cam lobe surface strengthening, oil passage cleaning and timing verification to meet OEM Tier4 specification and support stable aftertreatment operation.

The cam lobes actuate tappets and rocker assemblies to control valve lift and timing, matching ECU fuel map and EGR system to balance power, fuel consumption and emission. Cam pitting, scored journals or shaft distortion will lead to timing drift, power loss, excessive emission and fault alarm.

It is made of alloy steel with heat-treated cam surfaces for outstanding pitting and spalling resistance. The Reman process strictly controls cam lift, helix angle and concentricity. It has good compatibility with matched camshaft bearings, hydraulic tappets and pushrods.

4. Drop-in ready without extra machining, cost-effective versus new parts and cuts downtime

FAQ 

Q: Can this camshaft fit non-Tier4 C9.3 engine?
A: Direct interchange is not recommended. Tier4 cam timing and lift are different, interchange will cause high emission and abnormal power.

Q: Does Cat Reman camshaft carry same warranty as new part?
A: Genuine Cat Reman has the same warranty, core return is required when purchasing.

Q: C9.3 uses hydraulic tappets. Do I need repeated valve lash adjustment after camshaft replacement?
A: Hydraulic tappets compensate clearance automatically. Follow manual assembly and check for valve noise after break-in.

Q: What secondary faults will blocked oil passages cause?
A: Insufficient lubrication scores cam lobes and journals quickly, tappet malfunction leads to timing fluctuation and engine derate.
