bit of a long winded story again sorry. Might've said somewhere, i went to retrieve my spare car battery from the neighboring farm, had it tied on the back of a chinese type 200 quad. As it turned out the quad had cried enough & sat down the paddock till the horse ate the seat off it [bugger--was a good seat]. Ended up bringing the whole bike home locked up in the drive somewhere which is why they 'just left it where it was'. Think i now own it whether i like it or not so decided it was in the right angle transfer box that cunningly just bolts on over the final drive shaft externally as a totally separate unit--quite neat & the same type motor is used for the chain drive quads & 2 wheelers [ this variation has reverse, below first gear]. Anyway, where was i--on dismantling i found 'not a drop of oil' & looks like it never did have from new but, doubt it. The bearings were in bits after the cages fell apart, then the balls rolled out & went through the two gears & took half a tooth off plus made a mess of the rest. But think i can get it going for a bit longer before selling it for parts or good chain drive motor. So found my common old bearing [under the bench trick] fitted two hols but the third was bloody odd, super small ball bearings, large inner race & not 'that' large outer so phoned the local bearing place & had one, but $45 stopped me [being a cheapskate], the old-fix it but 'don't' spend any money trick. So googled the measurements & "$3.95 u.s. with free shipping from China". Won't be the same quality as $45 but should do the trick [i hope]. Sorry to stretch the story out but just couldn't get over the variation in cost. Reminds me of when i shot my genuine yamaha multi tester to smitherines, i was certain i'd turned the hot water cylinder off before testing the element--anyway--similar ability type multi testers locally were expensive so, similar story, $5 or something from China with free shipping & has worked great for a few years. Cheers.
