634-2549 right cylinder bank camshaft CAT spare part

Advantages

• Maintains valve timing across the engine speed range.
• Promotes effective fuel combustion and exhaust regulation
• Supports variable valve timing mechanisms.

1. Unified cam profile for whole right bank, consistent valve phase and stable power output
2. Mirror ground cam surface, low friction, reduce pitting and spalling under high temperature
3. Strict coaxiality control for multiple journals, uniform bearing load and low seizure risk
4. Independent right bank replacement, no left bank disassembly required, save overhaul time and cost

FAQ 

Q1：Can 634-2549 replace left bank camshaft of the same engine?
A：No. Cam phase, lobe layout and locating structure are dedicated for right bank, not interchangeable.
Q2：Must left bank camshaft be replaced together with 634-2549?
A：Not mandatory. Inspect left bank camshaft separately and replace it if worn severely.
Q3：What to check first if all right bank cylinders have high exhaust temperature after replacement?
A：Check timing phase, valve clearance, stuck tappets and cam bearing clearance first.
Q4：How to protect cam lobes during long time storage?
A：Clean cam surface, apply anti-rust oil, wrap with anti-rust paper, support on journals instead of cam lobes.
