REAR SUSPENSION LINKAGE
The rear suspension of all TM motorcycles is equipped with a conrod and
rocker mechanism that gradually modifies the leverage ratio between the
wheel and shock absorber.
This mechanism works on the bearings, which must be cleaned and greased
at the scheduled intervals to keep suspension operation efficient.
When washing the motorcycle with high pressure cleaners do not direct the
jet at the suspension linkage.
CHECKING CHAIN TENSION
- To check chain tension, put the motorcycle up on the center stand.
- Push the chain upwards at the end of the chain guide.
The upper branch of the chain must be taut.
The distance between the swing arm and the lower branch of the chain (A)
must be approx. 10 - 15 mm. Adjust the tension if necessary.
DANGER
- IF THE CHAIN IS TOO TIGHT, THE FINAL TRANSMISSION
COMPONENTS (CHAIN, PINION AND SPROCKET, GEARBOX AND
REAR WHEEL BEARINGS) ARE SUBJECT TO MORE STRESS. IN
ADDITION TO PREMATURE WEAR, IN EXTREME CASES, THE CHAIN
OR THE GEARBOX SECONDARY SHAFT MAY BREAK.
- INSTEAD, IF THE CHAIN TENSION IS INSUFFICIENT IT CAN JUMP
OFF THE PINION AND LOCK THE REAR WHEEL OR DAMAGE THE
ENGINE.
- IN BOTH CASES YOU CAN EASILY LOSE CONTROL OF THE
MOTORCYCLE.
