How to Change the Chain Case Oil in a Polaris Snowmobile
- 1). Place an oil tray under the chain case. This will catch the oil when you open the chain case. Use an empty windshield washer container cut to size as a quick DIY oil tray.
- 2). Remove the chain case cover using the socket set. There will be several bolts around its perimeter securing it to the chain case.
- 3). Drain the oil into the tray and wipe the bottom and inside of the chain case clean with the shop rags.
- 4). Inspect the condition of the gears for any abnormal wear. If you discover a fair amount of metal filings in the bottom of the chain case, you may have problems. Some metal filings will be normal wear and tear.
- 5). Place the cover back on the chain case and secure it with the bolts you removed. Tighten it snugly, but not so tight as to strip the aluminum chain case bolt holes.
- 6). Add oil to the chain case in the quantity recommended by Polaris. This information can be found in the owner's manual.
