Measuring the Compressed Plastigauge
Note
The camshaft ladder is unique to each cylinder head and is, therefore, not available separately. If the
camshaft ladder is worn or damaged, the complete cylinder head must be replaced.
Calculate the journal clearance using the Plastigauge chart supplied with the Plastigauge kit. 6.
For specifications refer toCamshafts. 7.
If the clearance measured is within the specified tolerance, remove the cap/ladder and clean off all traces of
Plastigauge. Assemble the camshafts (see Camshafts - Installation). 8.
CAUTION
Although Plastigauge is oil soluble, all traces of the material must be removed to prevent blockage of the oil
drillings and resultant engine damage.
Camshafts - Installation
WARNING
Before starting work, ensure the motorcycle is stabilised and adequately supported. This will help prevent it
from falling and causing injury to the operator or damage to the motorcycle.
CAUTION
The camshaft sprockets are attached to the camshafts using slotted bolt holes. This allows for very accurate
valve timing and therefore improved performance and fuel economy.
Never fit the camshaft sprockets without correctly setting the camshaft timing using the service tools and
timing procedure described below. Severe engine damage will result from incorrect valve timing adjustment.
Check that T3880601 - Crankshaft Timing Pin is installed. Ensure the crankshaft cannot rotate. 1.
Thoroughly clean the camshafts and journals. Inspect the ends of the camshafts for correct fitment of the
sealing plugs. Lubricate the camshafts with clean engine oil before fitting to the cylinder head. 2.
If removed, refit the camshaft sprockets noting their orientation, and secure using the original bolts. DO NOT
tighten the fixings at this stage, the sprockets must be free to rotate. 3.
Refit the camshaft drive chain and if removed the tensioner blade and rubbing strip (see Camshaft Drive
Chain, Tensioner Blade and Rubbing Strip - Installation). 4.
Note
Locate each camshaft to the head ensuring the camshafts are correctly identified (inlet and exhaust)
and are also correctly located over their respective valve banks.
Refit the exhaust camshaft to the cylinder head, hooking the camshaft drive chain over the sprocket as you
do so. 5.
