    GP1200R new Crank

    I recently purchased a new hotrods crank for a 2002 GP1200R. I am helping a friend fix his destroyed engine as he who has no idea.

    I will admit that I have only ever rebuilt the standups (ie: 2 cylinder rather than the three cylinder) down to this level. It's pretty similar.

    I have the service manual and have followed a "how to thread" from this site (which has been helpful).

    The issue is that once installedthe crank is installed and the crankcase torqued it is REALLY tight - it does not spin over freely by hand and almost feels like something is binding.
    It is not grabbing just tight and I don't ever recall the twins I have replaced cranks in being this tight. As a guess is takes about 5 ft lbs of torque to spin it over.

    I have pulled it apart twice and double checked location of things to be sure but it is OK. Is this normal for a triple until it wears in?

    Hope someone can help, thanks in advance.

    regards, Mal.

    Hey Mal welcome to the Hulk.

    I would send the crank back. Hotrods cranks have been know to be tight.

    Grr...

    Thanks Beerdart.

    I was hoping it that it wasn't , however, I thought that may be the case.

    I live in Australia and the issue is that I bought it from the US. It cost a fortune to get it here and it will cost big $$ to turn a new one around....especially since the exchange rate has changed so much in the past 2 weeks.

    Wait for others to chime in to see if they have any-other suggestions. My feeling is it got knocked out of whack in shipping. Is there any crank shops around that could check the runout and phasing?

    crank update

    Thanks Beerdart.
    I found this http://www.greenhulk.net/forums/show...t=84866&page=1 - OMFG!!

    Panic has set in - I've disassembed again and degreased the crank, cleaned and blew it out with compressed air, 1/2 can of WD40 and soaked it in 2 stroke oil for a few hours.

    It definitely spins more freely now - AND it spins OK sitting upside down in only one half of the crankcase with all the breaing and seal on.

    As soon as I put the second half on and torque it down it is now harder to turn and won't spin freely.
    I can sping it by hand with the driveshaft coupler - but it is not spinning freely.

    Clutching at straws - Is it possible that the brand new crank seals (WSM) that need to bed in or is it that case stuffed HotRods crank strikes again?



    Regards, Mal...

    From the buyer seller feedback section, http://greenhulk.net/forums/showthread.php?t=109498
    all I can say is keep sending it back until you get one that works. I made this a sticky so it is always at the top of the section, in hopes people would see it.
