    can you re-use OEM conrod bolts?

    im rebuilding i 2005 rxp and want to change the cam chain (crank still bolted up to con rods)

    is the only way to get the new chain on, to undo the conrods and lift the crank up?

    if so can i re use the conrod streach bolts?

    cheers

    You can change the timming chain without removeing them. Just remove the oil squirters all 3 and lift the crank enough to get the chain out. Yes, it is kinda a pain, but I have done it many times for SCer clean up. BUT you say you are rebuilding the motor? SO why not pull it all apart and inspect everything? Then just hone and new rings or if needed piston and rings?

    PLus one.
    I know this all to well as i forgot to put the chain guide in one time.
    I caught it before I put the cases together but had to remove the oil squiters and lift the crank up far enough to get the guide in place.

    If you do remove the rod bolts, replace them.

    thanks for the feed back.
    ive now ordered a full conrod bolt set with other parts needed.

    ive had to replace one (rear most) piston due to damage from valve falure.

    the bore was really good, so very lightly honed and fitted a new piston/rings.

    at this point in the rebuild then.... would you guys pull the other two pistons, replace rings/lightly hone and start over? or leave the other two pistons alone???

    its a 2005 jetski with 60hours. the "other two" pistons/bores i have not yet touched look ok.

    note that the damaged piston that i removed (top face only) had a 'stuck' top piston ring (it wont move outwards)
    so should i renew the other two ring sets?

    im replacing one main crank bearing (fuel tank end) as it looks as though its "scrubbed/deposited" possibly from hard throttle from cold. the crank face for that bearing is perfect.

    ive had the head welded and skimmed .004" and am yet to get seats cut and new SS valves fitted.

    all this sound ok??? fitting new cam chain too, and flywheel bolts.

    the sc has been rebuild recently too with metal washers.

    thanks again

    I would pull all pistons and get the bores honed/new rings at least.

    Check your connecting rod to make sure it's straight

    Good luck - the rebuilding is kind of fun if not for the expense and delays
