description

This 431-1481 rear camshaft is forged from vacuum refined alloy steel. Its cam profile is designed for rear cylinders of G3516C gas engine, with reinforced bearing journals. It does not come with pre-assembled gear and transfers torque through rear coupling structure. It forms a complete timing system with front camshaft and controls air intake, exhaust and gas supply for rear cylinders. It solves low power, transmission noise and unstable combustion on rear bank. Gas engine requires strict phase matching between front and rear sections. It cannot be replaced with diesel camshaft or separate left/right bank camshaft, suitable for long stable gas power station operation.

Part No.：431-1481
Name：Rear Camshaft
Material：Carbon Steel
Process：Integral forging, carburizing quenching, precision grinding
Package：Camshaft only, gear and spacer sold separately

Advantages

  1. Custom timing curve for rear cylinders, calibrated with front camshaft to keep gas injection synchronized
  2. Thick hardened journal surface, resistant to alternating torque and journal wear
  3. Precision flange tolerance, small transmission clearance and lower timing skip risk
  4. Split single shaft design, only replace damaged rear part instead of full assembly to cut maintenance cost
  5. Cam profile, journal roundness and concentricity inspected one by one, ideal for bulk power station spare stock

FAQ 

Q：Can 431-1481 rear camshaft replace 431-1480 right bank camshaft?
A：Not interchangeable. Different structure, mounting position and timing phase will cause binding and valve collision.

Q：Can the camshaft be reused after light journal scratches are polished?
A：It can be used temporarily if dimension stays within tolerance. Deep grooves require replacement to prevent seizure.

Q：How to store this rear camshaft?
A：Place horizontally on dedicated support, avoid direct ground contact. Coat cam lobes and journals with anti-rust grease and cover from dust.

Q：Is oil and filter change required after replacing this rear camshaft?
A：Recommended, to prevent hard particles from wearing new cam lobes.
