DRIVING CHAIN
The chain durability depends on its appropriate lubrication and regulation. A lack
of maintenance may lead to early wear or damage of a chain transmission and sprockets. It
is necessary to check and lubricate the snowmobile driving chain from time to time.
The chain transmission unit of the snowmobile onsists of:
1. Brake wheel;
2. Caliper;
3
. 3. Driving sprocket;
4
. 4. Control chain (chain 530, 22 parts)
5
.
5 5. Chain tensioner sprocket.
6
. 6. Chain tension adjusting mechanism.
For regulation of chain tension it is necessary to weaken the half nut, perform a chain
tension adjustment (bending of chain vertical reach pointed with an arrow at load of
about 5 kg should be not more than 10-15 mm), tighten the nut.
7. Driven sprocket.
Chain transmission condition check:
1. Put your snowmobile on an even surface, shift the transmission selector lever
to neutral position.
2. Check chain slack.
3. Move the snowmobile back and forth. Check driving chain slack. Chain slack should be unchanged.
4. Check sprocket teeth for possible wear or damages.
5. If chain transmission or sprockets have an excessive wear or damages they should be replaced. Never use a new chain with worn
sprockets, this will lead to a quick chain wear.
Lubrication:
A special low temperature lubricant should be used for snowmobiles chain. Every part of the chain should be
drenched so that the lubricant penetrate between joints of plates, dowels, slugs and rollers.
