Hi guys,
Has anyone successfully bypassed their A/C compressor with a different belt?
Like this one:
http://www.ebay.com.au/itm/Alternator-Fan-Belt-No-A-C-Holden-Commodore-VN-VP-VR-/380317868296
There is a belt for sale to bypass the A/C on a VN. I had a quick look at the serpentine belt with A/C. Wouldn't some engine part end up spinning backwards if you just used a shorter belt?
Or do you reckon this belt is just a normal length serpentine belt that goes around an idler pulley that sits where the A/C compressor would usually have been?
I note that some fleet models came without power steering, but the serpentine belt would be the same, because Holden used an idler pulley in place of the power steering pump. Just wondering if the same type of idler pulley setup is required if I ditch my A/C.
My A/C compressor is stuffed, don't have the cash for a rebuild so ZI would like to bypass the thing. I wish it had a separate belt like most other old cars did. I have seen a replacement compressor, but it is $500. I note that compressors are being pumped out of china, who nows if these are original or not.
What are my A/C compressor options?
anyone rebuilt a compressor from scratch?
do wreckers have "exchange" or "recon" units that are any good?
Has anyone heard of Holden having any lying around a dealership?
Any ideas anyone?
Cheers, Ben.

The VN's had the option of air con or no air con and have the belts to suit. So as long as it is routed correctly you should not have any drama's.

What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared. |

The best way to find out, is if you can measure where the belt goes around the pulleys, and count the number of ribs on the pulleys, you then take this to somewhere that specialises in hoses and belts, to see if they have anything in that size. Manufacturers like Dayco had a simple sizing system for V-belts:
Example: 11A0900. 11= widest part of belt A= type of belt, meaning A-section, 0900= inside circumference of belt in millimetres. I know they make rib belts, and if you strike out at automotive places, try some ag supplies shops. |

Thanks Mechknight73,
by the looks, 6PK1650 or equivalent is the belt for the job.
Here is a Bosch belt catalogue in pdf, it lists the "VN no A/C belt" on page 89.
There is also a complete list of belt part numbers for all vehicle applications.
http://www.bosch.com.au/content/language1/downloads/Drive_Belt_Web_Ready.pdf
Also found a Bosch one for sale here, probably better to go Bosch for $40 than an unknown brand off Ebay for $30 I reckon.

Thanks for the tips on decoding belts mate, but when I am digging around the back of ag supplies, I know my car is too old. Yes, I have restored and run many old cars.
This VN is just a daily driver, so I am not going to too much trouble.
Cheers, Ben. |

I should have clarified; when I meant ag supplies, I meand somewhere that sells parts like belts for things like headers, loaders and the multitude of farm machinery. The number of drive belts on an old header alone is a shocker. It's why many of the pulleys have more than one belt in the same circuit. I thought by fluke one of those belts might be a match.
I had also forgotten to mention, there is a place in NSW called Gardner Engineering. They are specialists in retrofitting Commodore V6 and V8 engines the classic Holdens. One of the options they offer is a belt to exclude the aircon, and a pulley to cover the power steering pump if you didn't want that on your EH Holden or HZ Kingswood |

Excellent, thanks for the tips mate.
I went through all the old part sourcing you could possibly imagine.
I used to be involved with restoration of 60s and 70s yank tanks.
I also used to try to find bits for Datsuns in motorsport applications.
I know what the hunt can be like. But this is a VN!
There is a dead one on every 3rd front lawn here in SA.
That is why I bought it - parts availability, they are common as. Parts are "on-shelf" not 3 months away via ship in Japan, like Datsun parts...
I just thought - Common car, widely produced, should be easy to get parts.
If I am digging around trying to find a belt for a 20 year old Holden, mere 5kms from the GM factory, then I have problems indeed.
I will grab the Bosch one off the shelf, easy!
Thanks guys, much appreciated.
Ben. |
