Now push a rag all the way through the air sleeve to clean the bore and inspect it for damage – an airborne rock could have dented the tube and damaged the seal or O-ring. Inspect the parts and replace them if they have nicks or cuts. It’s safe to use a product like brake cleaner to clean the parts, but it usually isn’t necessary. Wipe the scraper, seal and bushing with a shop towel. Step 4: Use a shop towel to clean the bore of the air sleeve. If Fox FLOAT shocks go too long without service, the dirt and debris could push through and damage the main air seal and cause the air spring to fail. The scraper, bushing and seal will be greasy, and this is where debris collects. Make note of the order and orientation for correct reassembly. With the sleeve in hand, remove the blue plastic ice scraper, the rubber seal and the Teflon-coated aluminum bushing. Twist the sleeve until it’s free from the shock, and then slide it off. If the sleeve cannot be removed by hand, use a strap wrench to loosen the sleeve. Now that the air spring has been discharged, grab hold of the air sleeve with a hand and turn it counter-clockwise to unthread it from the shock assembly. Twist off the cap from the Schrader valve (the valve you use to adjust air pressure) and relieve the air pressure. Step 2: If you can’t remove the air sleeve by hand, use a strap wrench like this one. With the shocks removed from the chassis and in a bench vise, use a flat screwdriver to pry the rubber chassis bushings out of each shock – this allows clearance so the air sleeve can be removed and serviced (the air sleeve is the larger tube). This service is different than a shock rebuild, which requires full disassembly, and special tools and knowledge to change the oil and charge the nitrogen. These nine easy steps – originally published in the January 2009 issue of Snow Goer magazine – explain how to remove the air sleeve, clean and lubricate it, and reassemble. Shocks for snowmobiles get blasted with ice, snow, dirt, rocks and other debris that, for FLOAT shocks, could cause them to lose air pressure. Supplies are available from Fox.Ĭan you twist the cap off a bottle of beer? If so, you can perform routine air sleeve service that’s required to maintain good bump-damping performance from Fox FLOAT air shocks.
