Red face Broken Chain Guide - Mechanical Tensioners

Techies,

Upon disassembly I found the drivers side upper tesioner in pieces. Amazing that the motor still ran well. Lucky it didn't slip timing (I have only driven it home from where I bought it.) At least I know where the funny flapping sound was coming from.

Can I assume I have a bad tensioner on that side?

With all the talk of tensioner failures regardless of style I was thinking of going with mechanical tensioners. I don't mind a little periodic maintenance and the savings are big allowing expenditures in other areas, like chains & sprockets.

Can anyone correctly describe the setup & adjustment procedure for mechanical tensioners? Any brands to recommend for any reason?

All feedback is welcome.

Bill

You mean solid tensioners? It's a great way to destroy your engine - read up on this in the Engine Rebuild Book.

I recommend the Carrera Chain Tensioners. Nowadays, they are the same price as the older spring-loaded ones...

I bought rebuild kits for my tensioners some time ago. I will likely go that way with the locks for back up.

I heard there is a difference between the OEM rebuild kits and the aftermarket. Any comment?

BTW, I now your book for procedures, great book.

Thanks,

Bill
