description

This is a complete valve-train assembly for classic Cat engines. The camshaft and timing gear are pre-mated and phased at the factory with crack testing and dynamic balance verification, different from bare camshaft spares. The 3116 and 3126 are early electronic engines with hydraulic lifters. Cam timing controls cold start performance and idle stability. Its cam profile is unique to this engine family and cannot interchange with later C7 or C9 series. It fits 320B,322C excavators, M318 wheel excavators and 938G wheel loaders, widely used for legacy fleet repair and emergency jobsite service.

Product Advantages

1. Pre-timed gear and camshaft with verified backlash, eliminating repeated phasing work on site and cutting overhaul time for legacy engines.
2. Full dynamic balance reduces gear housing vibration and slows fatigue wear on lifters and bearings.
3. Original cam profile matches early fuel control logic for reliable cold start and smooth low-load operation.
4. All-in-one package simplifies sourcing without separate gear hunting, convenient for stocking older fleet spares.

FAQ 

Q: What is the relation between 0R-9434 and 134-5276?
A: 134-5276 is bare camshaft, while 0R-9434 is a complete assembly with matched gear. The cam core is identical.

Q: How many 0R-9434 assemblies are needed for one 3116 engine?
A: 3116 is inline engine, only one camshaft assembly is required per engine.

Q: Can I keep the old gear as spare?
A: Yes, but the pre-calibrated gear supplied with this assembly should be used for the current overhaul.
