CHAIN WEAR
To check chain wear follow carefully the instructions given below :
put the gear into neutral, pull the upper part of the chain in an upward
direction with a force of 10 - 15 kilograms (see figure). Now, measure
the distance of 18 links on the lower part of the chain. If the distance
exceeds 272 mm it is advised to replace the chain. The chains are not
always worn in a even way. For this reason the measurement must be
taken in different points on the chain.
INDICATION:
When a new chain is mounted, also replace the sprockets. A new chain
wears more quickly on old and worn sprockets.
WARNING
WHEN THE CHAIN SPROCKETS ARE REPLACED, IT IS ADVISED TO MOUNT
NEW SELF-LOCKING NUTS AND TO TIGHTEN WITH CROSS SEQUENCE.
TIGHTENING TORQUE AT NUTS 35 NM.
BASIC INDICATIONS FOR TM DISC BRAKES
CALIPERS :
The mounting system of the calipers of these models is “floating”, i.e they
are not rigidly joined to their support. The lateral compensation always
allows the pads to work in the best way on the discs. The brake caliper
fastening screws must be assembled using Loctite 243 and tightened
at 25 Nm.
The front calipers of the SMR/SMM models are an exception as they
are fixed-type.
PADS:
The minimum thickness of the friction material cannot go under the limit
of 1mm.
In case of replacement, it is advised always to use TM original spare
parts for your motorcycle.
BRAKE DISCS:
With wear the thickness of the brake disc is reduced in the contact area
of the pads (1). In the thinnest point (A) the brake disc may present max.
wear of 0.4 mm with respect to original thickness. The original thickness
can be measured in point (B) outside of the contact area. Check wear
in different points.
- BRAKE DISCS WITH WEAR EXCEEDING 0.4 MM ARE A RISK FOR SAFETY.
WHEN THE LIMIT OF WEAR HAS BEEN REACHED, HAVE THE BRAKE
DISCS REPLACED IMMEDIATELY.
- IT IS COMPULSORY TO HAVE THE BRAKE UNIT REPAIRED BY A TM
AUTHORISED WORKSHOP.
