Idler pulley (torque spec) & Clutch fan delete (what's the purpose)

[jws123]

If you cant tighten a bolt as simple as a idler pully by feel without a torque wrench you probably shouldnt be working on your vehicle just my 2 cents.

wrong bolt there, einstein.

also, stop spreading misinformation

Next time make sure you torque it to the recommended 250 ft lbs. That better?

When I was observed using both my inch pound and foot pound torque wrenches whilst building transmissions at the dealer, I was lambasted and put down. Funny thing, though... I had low single digit recheck/ comebacks, and even fewer troubles that ever came back to workmanship, while the blowhards had many. many more.

When bolts go into soft aluminum, the torque specs are very critical. Perhaps you have calibrated hands!

I think Archimedes was onto something, eh?

I think they call that torque "elbow"

So what is the consensus on the torque spec for the idler pulley bolts? According to this thread alone, we have one unfortunate soul who broke off the bolt attempting to torque to 45 ft. lbs., and another who did so at just 30 ft. lbs.

The Factory Service Manual for my 2008 Dodge Ram 1500 (5.7L) lists the correct torque as being 40 ft. lbs. per PDF page 1,419:



Is this a misprint, given the broken bolt experiences listed earlier in this thread? For sake of reference, I found a post in a 2014 Challenger forum which lists the idler pulley torque spec at just 21 ft. lbs.

Purely a personal opinion but I have never used a torque spec for an idler pulley bolt. On any car I’ve ever owned from a mustang to a civic the pulley is mounted on a cast aluminum stub. The pulley doesn’t ride on the stub, it rides on the bearing pressed into it. The stub is merely a mount to hold the pulley in place and the direction of the anchor bolt threads is the same direction as the rotation. I go hand tight till the bolt bottoms out against the pulley and a less than a quarter turn more. I know this is anecdotal and not the proper professional way to do it but I’ve never had a problem with my simple minded method.
