Horseshoe Cam Tensioner bolts - not happy with the threads question.

(1/3) > >>

McCabe-Thiele (Ted):
Today I went to put back the horsehoe tensioner bolts I am less than happy with one of the bolts as I began to tighten them up (I was aware of this previously but it seems worse). One bolt went to an initial 4 N-M but the second was not tightening up as it should so I am pretty sure the thread is worn and starting to strip.

I put some Locktite on both threads and all was clean before assembly. What are the forces at play on the tensioner is it possible that it could come adrift with just the one decent bolt?

I suspect either the PO has had it off before or the threads have been worn by the vibration through the seized  horseshoe?

Question is what can be done to the casing threads to fix the problem are there any best options?

Bryanj:
Helicoil both of them

TrickyMicky:
Just a salient thought to throw in, if you are going to purchase a helicoil set, shop carefully. I have been buying a lot of bits and pieces from White Rose Tools, and have been 100% satisfied. They stock a thread repair kit by Sealey at £135. They also stock EXACTLY the same kit under the Blue Spot brand at £36!!! Haven't used mine as yet, but it looks the business.

Depends on fuel cost but you can brig it to me in Glos and i will do it for you

Thanks for the offer but you are a tad too distant - I will go to the engineers who did my tensioner screw insert and have it helicoiled. I have read on here somewhere of another brand / type of insert but can't bring the name to mind.
