tensioner bolt hole stripped...what can be done? Help?
 

just wanted to know what can i do to fix the problem when the z6 engine belt tensioner bolt hole is stripped? what can i use to rethread it. The bolt hole uses a 14mm bolt but the hole seem to be larger than the bolt itself. What can i buy to fix it? not sure what to buy at sears.

helicoil thread repair

Re: tensioner bolt hole stripped...what can be done? Help?
 

what thread pitch should i get it and where? does sears sell it?

i can use the helicoil thread repair even if the bolt hole is larger than the bolt itself? Or do i need to get something to insert in the hole?

You insert a helicoil in the hole and it will retain the original diameter even after the hole is been enlarged.Go hit up the parts store with the original bolt to referance for size.

i believe it is 10 x 1.25mm
you can use time-sert thread repair also.

so is there a helicoil for 10x1.25 mm thread repair? or is it basically a universal kind of thing? what size do i ask for?

Bring your bolt to Napa and tell them what you want. They will have a helicoil kit/repair kit for you.

damn a heli coil kit is $60????? cant i just buy the insert and use just a needle head plier to insert it in? i know the plastic tool isnt worth $60.

you have to tap out the stripped hole to a larger size.
some kits come with a tap and those are expensive.
if you have a tap already, then you just need the inserts.

The other option is to weld the hole, drill and tap the correct size. the problem is getting in the exact location as stock.

fill the hole with JB weld, wax the bolt and stick it in. when it dries you are set. just another option. personally i would do the heli-coil

Re: tensioner bolt hole stripped...what can be done? Help?
 

been there. my tensioner broke off in the block, ---- it up trying to extract it, tried so many different types of insert nothing works the all worked loose after startup. so I went on ebay, found this british guy selling some inserts that when you install them there is some kinda pressure activated glue on the threads, installed the bitch with a standard fine thread bolt, and I never had that problem ever since.. if you would like to have one if you dont have any luck, I could send you one.
