    Rocker arm shaft bolts

    To discard or reuse???

    Riva says to discard....

    I am about to upgrade my retainers here soon, is it a good idea to reuse the old bolts or go to the dealer and order some new ones??? Whats the price tags of these babes??


    Thanks ahead of time...

    When it is a customers ski I replace them and torq to spec.

    But If it is my boat I reuse them. I may be a black cloud here, but all it does is hold the rocker shaft to the head. Can it really not be torqed propperly if it is reused and if it is off by a little bit does it really hurt?

    But they are one time use stretch bolts.

    At 200 Hours on my ski when we did the valvetrain upgrade, for the $35 I replaced them. Then when I did the head gasket at 215 hours (only had 15 hours on them) I replaced them again. Figured I was spending $300 to do it right with ARP studs I might as well spend the extra $35 again and just put new ones in there again. Thats just me, I am very picky though.

    Someone mentioned in a PM to me a while back that there were some non stretch bolt style rocker arm bolts but when I went through all the searches I could not find any info on them so I went stretch bolts. The general consensous when I was gathering data was that you can use them twice.

    New they measure 79.9 to 80.0mm, after one use they usually measure 80.2 to 80.3, after two times the usually measure 80.5 to 81mm. Shows me that its possible to reuse them once but will lose the tensile after that.

    There must be some service limit on all these bolts and would really like to know the facts verses just thowing them away only upon popular belief.

    Just my .02

    Im about to be doing some headwork on one of our skis and I was thinking about this myself. I was told that they can be reused once or twice.
    You can tighten them up and tell if they need replacing or not.. but im with Gus, for the price- better to have them on hand. Otherwise, youve got to make a trip to the dealer and order them while youre right in the middle of the job.

    You can buy them in the online store from Jerry if you need them

    Yep. I dont think they are too expensive either.

    One thing that I will attest to- In the past, when I have tried to cut corners, it has backfired a majority of the time. Over the years I have moved away from doing it all together for that very reason. It sucks having to do this twice because you thought you could 'get away' with it the first time. Now, these arent critical bolts.. but never the less, for the money why not do it?
