    Stripped thread on stator cover, Suggestions please

    hi everyone , i was cleaning my stator cover , replaced oil seal, and installed new stator from Ricks Motorsport.
    I cleaned all threads thoroughly and applied red loctite...
    I was tightening to 8NM of torque got to the last screw and it popped and stripped the thread. now it turns freely....

    Do i replace stator cover or try re thread it with a tap and die set... ?

    If its stripped simply running a tap into it won't help.

    I would suggest using a helicoil. Buy a kit of various sizes they are a very handy kit to have. Use the specially sized drill bit and clean out the hole then tap it out with the supplied tap and install the helicoil, be sure the break the tag off to lock it.

    This is all assuming there is sufficient material around the fixing point to do it. Def worth a go before going to a new cover.

    Another option is that these threads are pretty deep. Use something to gauge the depth and compare to the bt length and there may be a few more mm of undamaged threads and use a longer bolt.

    If this is possible, wouldnt try torquing it, just thread lock and gently nip it up with a t bar.

    i did notice that when i screwed the bolt on its own, it does go allot further past the damaged part and locks tight... I might find a longer 5m bolt.if its doesnt work ill use the helicoil...
    thankyou

    OK i fixed it, ran to the hardware , picked up a longer m5 0.8p bolt. You where right there is an extra 15mm of thread that was still good further down. for some reason the stock aprilia bolts only use 40% of the actual thread. I cleaned the thread wit the tap and die kit, and torqued everything down to 8Nm with red loctite....
    I purchased a helicoil kit just incase i face the same problem again when i put the motor back together... Im going to go and clean all the threads in the case, make sure there all clean, dry and ready for assembly..

    When i first purchased the bike the battery kept getting flat really fast, i measured the stator and only 2 parts out of the 3 had the right ohms. and the voltage to the battery never increased when i revved the engine. So i purchased a new stator and regulator..
    Af1 racing has everything you can need. I mostly search in this forum and get ideas on improved parts.
    You will laugh some parts are cheaper in the USA even after shipping, VAT and import tax than it is to buy the OEM part here in ITALY...and its MADE IN ITALY... i still cant figure that out.
    Hopefully next week once i get all the parts i can put the motor back together.
    i have 2 more small projects for the bike.. one has been done already with mixed results, but i am sure the other has not...

    Does anybody know if i placed the oil seal for the stator cover the correct way.. i had the spring facing towards the cover, and now i changed it to face towards the motor... i am confusing myself.. the picture on the forum isnt clear at all.

    No. It should be the other way. With the numbers and letters on the seal facing you. I.e flat side up as you are looking in. Then the washer with lip is installed with the lip facing you.

    Did you work on the aprilia xv assembly line?


    My bike is my gym, my wheelchair and my church all in one. I'd like to ride my bike all day long but I've got this thing called a job that keeps getting in the way.
