Sanden compressor belt size...

[Mikesmalaga72]

What size belts are are you folks using for Sanden compressor belts without idler pulleys? Continental references preferred but not absolutely required .... Thanks!

Mike, mine’s fitted with a 17325 belt.

(Behr AC with Sanden swap, no idler pulley.)

Standard 2002 sorry..... with Bluntech compressor bracket. Kinda thinking 13x840 Continental belt....but 

[visionaut]

Belt Length = 2C + 1.57 x (D1 + D2) + 1”

Where:
C = The distance between the crank and compressor shafts
D1 = The diameter of the small pulley
D2 = The diameter of the large pulley

Dayco top cog 17320 as recommended for the hobby Dave bracket. Works with blunt bracket as well.

FWIW…

 

I’m NOT using a HobeyDave or a Blunttech bracket, ( I think it’s an original Behr?).

 

Blunttech calls out a 13x810 belt for their AC Compressor bracket…

Thanks guys!!

Old picture from my 73tii with Behr AC and old York compressor. Belt on left came in a “kit” from a supplier that is no longer in business. It was too short.

 

Belt on right worked fine.

With some newer retrofits, the belt may have to be fitted to the compressor BEFORE the compressor is mounted to the bracket.  It’s fine if you have three hands😉.

Your compressor is cracked on the left side

Yep. Good eye Steven. The upper bolt hole has been like that for 10 years… no issues so far. I see a new compressor somewhere in my future

I noticed that as well.  My e30 came to me with a broken compressor mounting bracket. I had a friend weld it together.
