1. Dedicated cam profile for left rear bank, phase matched with right front camshaft for balanced power output
2. Mirror ground cam surface, low friction heat, less risk of pitting, spalling and scoring
3. Strict coaxiality control for multiple journals, uniform bearing load and slow eccentric wear
4. Single left rear camshaft replacement available, no full engine disassembly required, save overhaul cost

FAQ 

Q1：Can 581-3303 replace left front camshaft of the same engine?
A：No. Cam phase, lobe layout and locating structure are different, front and rear are not interchangeable.
Q2：Must all other three camshafts be replaced together with left rear one?
A：Not mandatory. Inspect other camshafts separately and replace them if worn severely.
Q3：What items should be checked first if exhaust temperature of left rear cylinders is high after replacement?
A：Check timing phase, valve clearance, stuck tappets and cam bearing clearance first.
Q4：How to protect cam lobes during storage?
A：Clean, apply anti-rust oil, wrap with anti-rust paper, support on journals instead of cam lobes.
