Started T Belt R and R in April on my 86 early USA 32 V car. Been using Dwayne's guide. This is 4th time I've dome T Belt on this car. - owned it since 1992.

I have replaced cam sprockets, rebuilt tensioner, did not replace WP. Thought I had marked everything properly but today have a M8 x 1.25 x 75 mm long bolt that I can not figure out if I mislabeled, did not install , is a spare from another project or ????. Can not find a M8 x 75 mm in PET for tensioner, power steering bracket / pump, alternator brackets, etc. Looked everywhere on the work I've reassembled and cannot find a missing bolt. Can any of you help me? No flames, I am having a senior moment!

Looks like it’s the bolt that holds the center timing belt cover on it also passes through the tensioner mount look just above the tensioner where the cover is attached to the tensioner

(Tensioner bolt is 55mm.)

Is it for a 928? Does the bolt head say Kamax?

There are no 75mm that I can find, anywhere in PET or Billy-Bob's torque list.

Ken - Unsure if it says Kamax - will look. PET does not have noted the 13 mm bolt head / 8 m that holds the plastic T Belt cover and goes through the tensioner in post 2 above. Later tonight I will remove the bolt I installed there and see how deep it is . I am a bit paranoid because I've been intermittently working on this T-Belt replacement now for two and a half months due to heavy work schedule. I am fairly certain there are no bolts of this size that hold anything else behind the t belt cover (that is now on along with accessory drives and belts)

There are M8 x 75 bolts on 928s, but they're not on 78-82, nor 87-95. The two I have here, one is a LOBO and 1 is an ESKA. PET is unusually bad about the lengths of the bolts on the tensioners, the numbers quoted for S4+ cars are wrong.
