description

Different from bare camshaft parts, this assembly is pre-fitted and calibrated with timing gear under Cat Reman quality control. The core is cleaned, crack tested, reground, and gear meshing clearance is verified. On C7 engines, this assembly drives valve train and coordinates electronic fuel injection, governing idle stability, throttle response and exhaust performance. It matches 324D,325D,329D excavators, 950H wheel loaders and 140K motor graders, suited for jobsites with frequent start-stop and variable load.

Maintenance & Replacement Tips

Mark crankshaft timing before disassembly. C7 electronic engines are sensitive to timing error and misalignment will cause valve-to-piston collision. Replace matched lifters, cam bearings, thrust washers and oil seals together. Lubricate all friction surfaces fully before installation. Check gear meshing smoothly during manual rotation. Run idle break-in first then load gradually, monitor oil pressure and valve train noise.

FAQ 

Q: Can 10R-8729 interchange with 212-4288?
A: The cam core is identical. 10R-8729 is a complete assembly with gear, while 212-4288 is bare camshaft. Select based on whether a matched gear is needed.

Q: How many 10R-8729 assemblies are needed for one C7 engine?
A: C7 is inline engine, only one camshaft assembly is required per engine.

Q: Can I keep the old gear if this assembly comes with a new gear?
A: No, the assembly is supplied with pre-calibrated gear. Return the old gear along with the core unless kept as spare.
