ENGINE DISASSEMBLY / INSPECTION - TOP END
Valve Cover Removal
NOTE: The valve cover can be removed with the
engine installed in the chassis.
1. Remove the (4) valve cover shoulder bolts (A) and
isolators (B) using a T40 driver.
2. Replace isolators (B) and valve cover seal (C) if oil
leaks are evident.
3. Remove the spark plugs (D). Stuff spark plug holes
with shop towels to prevent anything from falling into
the combustion chamber.
Camshaft Removal
NOTE: The camshafts can be removed with the
engine installed in the chassis.
1. Rotate the engine so the PTO cylinder is at Top Dead
Center (TDC) to relieve most of the valve spring
pressure. The camshaft lobes should face out and
the slots on the end of the camshafts should line up.
2. Remove the hydraulic cam chain tensioner (E) from
the cylinder. Replace the sealing washer (F) upon
reassembly.
