CAMSHAFT JOURNAL
Check the camshaft journal surfaces of the cam-
shaft holder and cylinder head for scoring,
scratches or evidence of insufficient lubrication.
CAMSHAFT OIL CLEARANCE
Do not rotate the
camshaft during
inspection.
Wipe any oil from the journals of the cylinder head,
camshaft and camshaft holder.
Install the cam chain onto the camshaft sprocket
and install the camshaft into the cylinder head
(page 8-22).
Lay a strip of plastigauge lengthwise on each cam-
shaft journal and be sure to avoid the oil passages.
Install the dowel pins and camshaft holder onto the
cylinder head, being careful not to drop the
plastigauge.
Apply oil to the threads and seating surfaces of the
camshaft holder bolts and install them.
Tighten the holder bolts in several steps according
to the numerical order cast on the camshaft holder
(1 thru 8).
Remove the camshaft holder and measure the
compressed plastigauge at its widest point on the
camshaft to determine the oil clearance.
If the oil clearance exceeds the service limit,
replace the camshaft and recheck the oil clearance.
Replace the cylinder head and camshaft holder as a
set if the oil clearance still exceeds the service limit.
