609-9409 left rear engine camshaft CAT generator spare part

Advantages

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

1. Dedicated cam profile for left rear bank, phase synchronized with other three camshafts for stable combustion
2. Mirror ground cam surface, low friction, reduce pitting, spalling and scoring under high temperature
3. Strict coaxiality for multiple journals, uniform bearing load and low seizure risk
4. Single camshaft replacement available, no full engine disassembly required, save overhaul time and cost

FAQ 

Q1：Can 609-9409 replace 609-9390 left front camshaft?
A：No. Lobe layout, timing phase and locating structure are different, front and rear are not interchangeable.
Q2：Must other camshafts be replaced together with 609-9409?
A：Not mandatory. Inspect other camshafts separately and replace them if worn severely.
Q3：What to check first if left rear cylinders lack power 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.
