Cat com 3 adapter
<Models with electric speed sensor>
• Measure the electrical resistance between terminals ➀ and ➁.
• If the measurement is out of specification, replace the speed sensor 1. P.11-55
CAUTION
Check the tightening torque of the engine speed sensor 1. If the sensor is insufficiently tightened, it may not produce signals.

Fitting side cover
• Apply an even, unbroken bead of sealant A to the side cover 5.
• Fit the side cover 5 onto the crankcase within 3 minutes of applying the sealant A.

Inspecting camshaft
(1) Cam lift
If any base circle-to-lobe height difference is less than the required value, replace the camshaft 11.
 

NOTE
Since the cams are tapered, they must be measured at the position A shown in the diagram.
B: Lobe height
C: Base circle diameter
D: Front of engine
(2) Camshaft bend
Support the camshaft 11 at its No. 1 journal E and No. 4 journal F, then take measurements at the No. 2 journal G and No. 3 journal H. If either measurement exceeds the specified limit, replace the camshaft.
