DanM1999 Posted February 20, 2012 Report Share Posted February 20, 2012 Hey, I have a rear magura on my Mod and I by accident put the bolt in sideways and I killed the threads... So my brother suggested getting a helicoil kit to fix it. We found one cheapish but just don't have a bloody clue how to use it. So can anyone share how to use them and sort out my bike. I am killing for a ride so come on guys help me out please!!! Cheers Dan.. XD Quote Link to comment Share on other sites More sharing options...

forteh Posted February 20, 2012 Report Share Posted February 20, 2012 The kit will have instructions in it Basically you need to drill out the old threads using the drillbit provided in the kit, run the tap down to cut the oversized thread and then insert the helicoil itself. You will need a tap wrench although you can do it holding the tap in the chuck of your drill and turning it by hand (never under power!). Its probably best to try to use a drill with a slow speed setting, will give you a bit more control over the process, you could probably turn the drill by hand (again) because youre cutting such a soft material. Its pretty important to make sure you drill straight and true into the brake mount. When cutting the actual threads, make one half turn clock wise, back it off a quarter to break the swarfe out and then continue clockwise again, repeat till you have sufficient thread depth. Dont worry if the inserts are only the same depth as the diameter of the screw and not as deep as the hole youve just drilled, it will be plenty strong enough and you wont need to put a second insert in there.

josh barker Posted February 20, 2012 Report Share Posted February 20, 2012 one thing i noticed watching that is that he didnt use any loctite on the insert, better to put some instead, as it could come loose Quote Link to comment Share on other sites More sharing options...
Philly_Biker Posted February 21, 2012 Report Share Posted February 21, 2012 The helicoil is a life saver. Kinda pricey but works well with aluminum. I've heard that when installed properly they are stronger than the original threads. Quote Link to comment Share on other sites More sharing options...

josh barker Posted February 22, 2012 Report Share Posted February 22, 2012 Pricey?Are you kidding me? he may be on about a full set, with all sizes, drills and taps. or the other sort where you can get a solid steel thread insert instead of steel wire insert, which tend to be more pricey, and are definatly stronger than the standard thread and stronger than the wire thread insert.

Philly_Biker Posted February 23, 2012 Report Share Posted February 23, 2012 (edited) Im just cheap i guess. I remember it was like 20 or 30 dollars for the kit (drill,tap,helicoils,instructions) for 1 specific size i needed. Came with plenty extra heicoils too, i only needed one. I guess it wasnt that expensive after all. Definity worth it cause they work and will get you back up and running.
