Secondary Transmission Chain Adjustment; Lubricating The Chain - Husqvarna 2004 SMR 630 Workshop Manual

Man 630-2004-IMP. D1 15-07-2004

Secondary transmission chain adjustment

Chain should be checked, adjusted and lubricated as per the Maintenance Chart
to ensure security and prevent excessive wear. If the chains becomes badly worn
or is poorly adjusted (i.e., if it is too loose or too taught), it could escape from
sprocket or break.
To adjust the rear chain it is necessary to lower the rear part of motorcycle so to
line up the drive sprocket axle, the rear swing arm axle and the rear wheel axle
as shown on drawing. Than let turn three times the rear wheel. Now the chain
should not be tight. (Fig. A).
Fast adjustment (Fig. B).
Push the chain towards the final part of runner and check that between the two ele-
ments a distance "A" from 0 to 2 mm is present.
If this is not the case, go on as follows:
- Unloose the fastening nut of the wheel pin (1) on the right side;
- Unloose the lock nuts (2) on both chain adjusters and turn the screws (3) to obtain
the correct tension value;
- Tighten the lock nuts.
After adjustment check that the wheel is lined up and tighten its axle.

Lubricating the chain

Lubricate the chain, following these instructions:
WARNING * : Never use grease to lubricate the chain. Grease helps to accumu-
late dust and mud, which act as abrasive and hepl to rapidly wear out the chain,
the sprocket, and the crown.
Disassembling and cleaning
When particularly dirty, remove and clean the chain before lubrication.
Work as follows:
Set a stand or a block under the engine and see that the rear wheel is lifted from
the ground.
1 -Remove the sprocket guard, the spring (1), the joint (2) and the chain.
2 - Check that the chain is neither worn out nor damaged. If the rollers or the links
are damaged, replace the chain by following the instructions given in the
Periodical Maintenance Table.
3 -Check that neither the sprocket nor the crown are damaged.
4 -Wash and clean the chain as described hereunder.
Washing the chain without OR (SMR 630)
Wash using either oil or diesel oil. When using gasoline or tricloroetilene, clean
and lubricate the chain to prevent oxidation.
Washing the chain with OR
Wash using oil, diesel oil, or paraffin oil. Never use gasoline, tricloroetilene, or
solvents, as the OR may suffer damages.
Use instead special sprays for chains with OR.
Lubricating the chain without OR (SMR 630)
First dry, then plunge the chain in a bisulphide molybdenum lubricant, or in high viscosity engi-
ne oil. Warm up the oil before use.
