Camshaft Removal
- Remove cylinder head as previously outlined. Remove fuel pump and fuel pump push rod. Remove oil distribution pipe. With camshaft still positioned at TDC for number one cylinder, open intake valve clearance on No. 2 and No. 4 cylinders.
- Attach a suitable pressure frame (No. 7003) to cylinder head to open all valves. Remove bolts securing camshaft thrust plate to cylinder head and carefully withdraw camshaft.
- Install camshaft in cylinder head and tighten down thrust plate. Set cylinder six to overlap and release pressure plate. The tapped hole in sprocket flange must align with cast protrusion in cylinder head (see Fig 1). Check camshaft endplay.

- Install oil pipe, making sure seals are installed above and below pipe at points where it is bolted to head. Front portion of pipe must measure 6.476-6.516" (164.5-165.5 mm) from middle of oil hole to front of pipe. Rear portion of pipe must measure 6.100-6.122" (155-155.5 mm). If pipe is not completely positioned, camshaft will not be properly lubricated.
- To install remaining components, reverse removal procedure.
