Re: what did you do to your motor bike today?
Putting a new engine on the Huffy today, had a internal failure of some sort that allowed the carnk to have too much in play and caused the mag rotor to eat into the block about 1/16" ruining the crank seal and the area that holds the seal in the block, engine was still running but started surging real bad and that was my first clue that I had an air leak, I figured it was a seal or intake gasket, so first thing I done was to remove the mag cover and bingo, loads of alum. shaving all inside the mag compartment and then I seen clearly what had caused the shavings when I noticed the rotor had eat into the block, I then pulled back and forth on the rotor and of coarse the crank just clunked back and forth to a major degree, I'm thinking that the engine has thrush washers on the crank that hold it a set distance and adjust the amount of end play it can have, it's been since last year since I've had the case open so I cant remember for sure, but it seems that I've lost those spacers or something else that allowed the crank to move to the side enough to cause all that damage to the block and ruin the crank seal on the mag side.
I have a spare engine that I unboxed and started preping for install in the next couple of days, hope it last more than 400 miles, one of my other bikes has 1180 miles on it now and runs like a top......
all of this problem happened on my way back from a 16 mile trip, I got lucky that I didnt get stranded and have to use my kick starter/peddles to get home.
wish me good fortune on this new engine guys.....
I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
