Shock servicing at a glance.

Dampers are one of the most critical components on a snowmobile. They contribute profoundly to many aspects of the snowmobiles performance, including handling, traction and comfort. With that being said… it is important to keep your dampers in perfect working condition in order to get the most from them.
We recommend that most dampers are serviced at least once a year to keep them in optimum condition. Dampers used in particularly harsh environments benefit from more regular service intervals.

General Shock Service:

Dyno check damper:

The damper is run on the Roehrig damper dynamometer to check for problems and to get an idea of its general internal condition. Several issues can show up on the dyno that would be hard to see just from looking at components once the damper is disassembled.

Dismantle damper and check components:

Next the damper is de-gassed and dismantled using specialist tools, the old oil is drained, and parts are cleaned and checked and replaced for new ones if they do not satisfy their requirements. Seals are replaced if required.

Make any valving changes:

With the valving components out of the damper, if any valving changes are requested by the customer they are made at this stage. If this service is requested we will valve accordingly to your weight and riding style.

Re-assemble damper:

The damper is carefully re-assembled with parts having been replaced where necessary, and specialist greases applied to relevant seals to ensure minimal friction and wear.

Fill with oil, and bleed the damper:

The final stage in assembly is to fill the damper with oil and bleed it to remove any air. This is performed with a vacuum filling machine when possible, some dampers require hand bleeding. The filling machine vacuums the damper to remove as much air as possible using a powerful pump, and then adds oil under pressure to ensure that no air is allowed into the damper.

Gas the damper:

The damper is gas pressurized with Nitrogen to its specified pressure.

Test damper on dyno:

Finally, the damper is run on the dynamometer to check that it is working correctly, and that any of the valving changes have the desired result. If anything doesn’t look right then the damper is disassembled, problems is solved/valving altered, and re-assembled. No damper leaves our shop until we are happy that it is in perfect operating condition.

Dynamic Spring Testing:
Along with damper servicing we are also able to check your spring rates on our roehrig dynamic spring rater. The spring rater helps us achieve proper spring setups for your weight and riding style.
