How to change the chain case oil The easy way on a Arctic Cat pro cross chassis snowmobile.

Thanks, great idea when you’re not going to do a tear down.

That chain case is a bullshit design. NO drain plug! Your vacuum pump method is the cats ass. Key is having a good vacuum pump with a vacuum reservoir like the one you show at the end. Great video. Pray for snow.

I would not recommend changing oil this way. The purpose of changing the oil is to clean entire casing of all filings as this is a wear item. . Pumping out the old oil and leaving the muky filings in is pointless
