FAQ 

Q1：Can 581-3305 replace 581-3299 right 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 581-3305?
A：Not mandatory. Inspect other camshafts separately and replace them if worn severely.
Q3：What to check first if right 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.
