FUEL TRANSFER PUMP PUSH ROD PROTRUSION
With the engine rotated to position the camshaft eccentric (1) as
shown, resulting in the lowest possible push rod (2) position with
respect to the cylinder head plain, dimension 'A' should be 0.96-
1.48mm.
If the proper clearance cannot be attained, measure the push rod (2)
length. The push rod (2) should be 152.45-152.65mm in length.
Replace the push rod as required. No other adjustments can be
made to change fuel pump push rod protrusion.
