Accessory brackets

[Dave Forster]

Does anyone have any pictures of an installation of the RCR supplied brackets for the air conditioning pump and the rest of the front accessories?

The attached pictures show one possible mounting arrangement for the air conditioning pump, but it is probably wrong as the arms on the bracket are a few inches too far back to align the pump's drive with the crankshaft pulley.

Also attached is a picture of where I think the tensioner pulley should go (top right of the picture), but there is an included idler pulley that I can't find a home for and it's not clear how the alternator would mount (there aren't any other brackets in the kit - does the alternator come ready to mount without a bracket?)

Dave,

The alternator bolts directly to the block with 0.4" spacers.

Dean can send you a pic of the AC bracket mount/tensioner mounts on Monday as I don't have one here at home

edit; found this one on the forum

Thanks! That helps.

Based on the picture, it appears that the a/c compressor is driven with a narrower, dedicated belt that drives off the back of the crankshaft pulley and only uses some of the available grooves on the compressor (i.e. the belt is narrower than the compressor pulley). This helps a lot for the alignment issue

Does anyone have a part no. for this belt, or is it just a normal LS7 compressor drive belt?

If anyone has any similar pictures showing the rest of the accessories with the RCR brackets and belt routing, it would be much appreciated.

Dean has all of the info you need and will be available for input on Monday

Dave -- after your mock-up measure the belt length needed, but I am using the same a/c bracket and the LS motor stock pulley system and this worked for me:

Gates® Micro-V AT® - OEM Quality Serpentine Belt

Part Number: K040365
Line: GAT

• 3 year limited warranty
• UPC: 72053008234
• Number Of Ribs: 4
• Width (In): 0.560 Inch
• Width (mm): 14mm
• Outside Circumference (In): 37.122 Inch
• Outside Circumference (mm): 943mm

These pictures are not of my build but had them saved on my pc. The photo taken from under the compressor... I sourced and used a longer bolt. One could also use two separate shorter bolts I'd imagine but one bolt would help to keep alignment and strength/integrity IMHO

One version of a belt set-up (mine). Rumbles also has a pretty slick set-up (check his build log) where he cut and modified the factory bracket that comes with the front accessory kit.

Keep in mind that the LS3 and LS7 front dress parts that we supply are also a little different from each other...

Dean will be happy to supply all the part numbers on Monday and all of this information is also being put into the latest round of updates in the online build manual...
