Mack2243 Posted February 22, 2015 Report Share Posted February 22, 2015 Hey guys, I have a quick question. I bought a shee a while back blown for 1300 bucks. It's bored .100 over, has the boost bottle, stock head, trinity stage 4 pipes. The guy had burnt up a bottom end rod bearing and was afraid to get into crank issues. Now I have it... I pressed the crank apart and had to take my die grinder and grind down the crank pin because there was brass and metal welded to it from the bearing. Got it all cleaned up, put new rods in it, took it out for 15 minutes and boom. Again. Bottom rod bearing. What's happening now is because I have taken material off the pin It heated up, moved towards the bearing and pinched it. I have new rods again. Will perma loctite hold the throw from moving or am I looking at welding it or a new crank. I do still have to press it apart and together. It's not like I can use my hands to take it off. It's an oem crank and you can't remove the bottom end pin from the inner throw. Thanks guys, Mack. Quote Link to comment Share on other sites More sharing options...
bigweav81 Posted February 23, 2015 Report Share Posted February 23, 2015 Just buy a Vito's, or hot rod crank. You will be ahead in the long run. Stock stroke to 4mil isn't to costly at all. Quote Link to comment Share on other sites More sharing options...
bigweav81 Posted February 23, 2015 Report Share Posted February 23, 2015 Your stock cylinders are bored .100 over? Did your bike shake like a queer eating a hotdog after removing material from your crank? New crank 350 to 450. Stories like this..........priceless.

trickedcarbine Posted February 23, 2015 Report Share Posted February 23, 2015 After you pressed it back together, how did you go about checking all clearances, run out, etc.? And did you weld the pin after it was trued up? Quote Link to comment Share on other sites More sharing options...

Mack2243 Posted February 23, 2015 Author Report Share Posted February 23, 2015 All clearances were checked with a dial indicator and a vernier. i didn't do anything to the crank after pressing it back together and tried it. That's my issue. Now my question is if I weld the crank, it'll be a one shot deal eh? If a bearing goes it's now a replacable unit? Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted February 23, 2015 Report Share Posted February 23, 2015 Use green lock tight all the jet ski cranks are green locktighted together, a lil goes a long way. More than likely it wasn't phased correctly , you need a jig to do it effeciantly Quote Link to comment Share on other sites More sharing options...

Mack2243 Posted February 23, 2015 Author Report Share Posted February 23, 2015 That's exactly what I was thinkin. That'll hold it eh? another thing that could be contributing to this is the jets. All the stuff that's done to it already and it has an open lid with k&n filter and the mains are 320 and it was -15*C when I took it out.
