Hey guys,

I'm reinstalling the pulley saver kit after having to do my alternator. one of the pulleys got in the way and had to be temporarily removed. does anyone have the torque specs handy? i don't have the instructions on me and can't get a hold of Rob at the moment.

thanks

 

When I designed the kit I followed standard military spec. parameters for the fasteners. Basically you tighten the fastener till it strips and then back the nut off 1/2 turn.

Actually I did not torque it as I used grade 8 bolts and snugged the nut till it was tight. Thats a subjective answer, sorry never thought that it needed a torque, just 6" wrench tight, no breaker bar used here. Woody

 

ok thanks. yah its pulley #10 in the diagram (specifically 38052).....i guess i'll just tigthen it 'till it feels good then? lol

thanks!

 

For all those people that will search on this the later....

NW Instructions State:
Idler Pulley Bolt: 20 Nm, 15 Ftlbs
Belt Tensioner Bolt: 25Nm, 18Ftlbs

 

yah. i came across those two numbers in the instructions. however, those are for two of the three pulleys. the pulley in question (my question) did not have a torque spec listed in that diagram those tq specs came off of

 

I do not think location matters, it is either an idler or a tensioner pulley.
Most important is to not overtighten and smash the bearing.

 

The manual refers to them as the Supercharger Idler Pulley and the Accessory Drive Belt Idler Pulley.

The Torque Specification Table in the Cooling section lists the S/C idler pulley @ 14 Ft. Lbs.

However, the installation instructions say to torque both pulleys along with the upper S/C mounting bolt to 15 Ft. Lbs.

I've ran across a few places in the manual where the table and instructions differ.

 

Sure would be sweeeeet to get the numbers off of the pulleys!

Gee there goes all the magic of the design, Woody

 

Thanks 70.
Thanks Woody.

 

Well...........

and MikeR made the first

Great info. Thanks, gents!

 

Woody did the original design and (frankenstien) fab of the pulley kit and brace. Then he gave it to Rob to refine into something we could buy. I just did a prelim of a bracket to keep the Idler pulley supported....

(well, I might have made a couple of spacers for Woody... )

 

and now the kit takes on another life!! c3 psk!!!
