Torquing a timing belt ??

[steptoe]

Once tried it with a torque wrench to be super precise, because the torque wrench had a reverse direction ratchet head on it. Discovered that the wrench not meant to torque anything left handed, and our Sube timing belts cam wheels need that on them to tension correctly. So, think that wrench then stuffed as not meant to go other way despite ratchet having that ability.
A net search shows I am not the only one. The factory manual shows a torque wrench on the job, calls is a tension tool, but the number given only refers to that tool as the adaptor to go between a torque wrench and cam wheel.

Never in my life have I seen a mechanic use a tension device other than wroist or elbow. Have trouble visioningh how a beam style torque wrench can click off at correct left hand torque value.

Anyone got correct device to do job other than wrist/elbow combo ?

Yep - you need a 'push-trough' type torque wrench ...

ah yeah, smart fella this Bantum! I calibrated my arm against the torque wrench in the vise, to about 12 ft/lbs and did it the usual way. I have an old cam wheel with M6 bolts in 4 holes to line up in fitted cam wheel, a centre bolt and nut to use a spanner on, and torque it from there.

Here are the tools I use to set cam belt tension on the EA82.




I think the pics are self explanatory, and yes that is the baby W&B reversible deflection beam t/wrench. Although the smallest of the 3 W&B I have twas the dearest:???:

the trusty old push through has its uses afterall !

I cheated by using a spare cam drive cog. Stuffed four m6 bolts so the bolt heads were inside, threads poking out front face, held in place with nuts. Face to face with the on-car cam wheel the M6 bolts line up with holes. M10 short bolt goes through centre hole of new tool with 17mm nut to use to get torque thing going with a spanner.
