CAMSHAFT 8970145730 suitable for NPR models equipped with 4BD1 4BC2 4BG1 engines

Product Design Philosophy

Cast iron camshaft for 4BD1/4BC2/4BG1 engines. Precision-ground cam lobes and journals ensure accurate valve timing, reliable performance, and long-term durability in NPR commercial trucks.

How it works

Driven by the timing gear, it rotates at half crankshaft speed. The cam lobes push tappets or rockers to open and close valves at precise intervals, controlling engine breathing.

Problems the product can solve

Fixes engine misfire, power loss, and valve timing errors caused by worn cam lobes or journals. Restores proper valve lift and engine performance in NPR trucks.
