I need a rubber boot that goes from the drive shaft housing to the transmission gear box! Best measurements i can get is 55 mm on gear box 75 mm on drive shaft swing arm side. Please help!

 

Let us know what make and model of machine. However, if it is Chinese, there may not be any spares back up. In that case you need to source a universal constant velocity boot, and cut it to suit, or repair the old boot using superglue. It is possible a boot for a Honda/Yam/Suzuki etc, may fit but unless anyone has one handy to measure, you can't know which, if any, will fit.

 

Going to the rear end

Coming from the transmission

Figure i would give a tire inner tube a try

 

This is what the original part looks like. Its from a 110cc chinese atv branded akuma.

 

Found the gear box on vmcchinesepaerts.com. Description says it also fits some Yamaha shaft drive models. Partzilla has them, but they don't provide measurements. Maybe you can contact them and see if they can give you more information about sizing.

 

Your the man! I wish i knew how you went about finding it!

 

I just searched Yamaha shaft drive boot.
