Removing the transmission chain / sprocket : Part One

Removing the rear shock-absorber

The shock absorber may be removed without removing the battery first, although the Yamaha Workshop Manual & some other non-Yamaha manuals say the contrary.

First remove the connecting arms 'aka dog-bones) & the rocker :
• Remove the connecting arm bolt (#1), shock-absorber lower bolt (#2) and rocker bolt (#3), extract the spacers :



The spacer on axle #3 may be difficult to extract. It goes out on the lhs. DO NOT use brute force or - worse - a hammer as this may destroy the alloy connecting rods !
Use an extracting tool, a tap, a hot air gun on the rods & freeze spray inside the spacer.
This is why a regular maintenance & lubrication of the rear suspension linkage is a must.



• Remove the shock-absorber upper bolt.
• Remove corrosion from the bolts & spacers, then protect with grease.


Job's done, the shock-absorber may now be cleaned and checked.
• Extract, clean and check all bearings from the rocker, lubricate with lithium grease then re-install.
• Check the swing-arm lateral free-play and correct rotation.

• Remove the main swing-arm nut on the right side (#27) :
