[95///M3]

I am taking the air pump off of my B36 this weekend. I will be retaining all of the bracketry, just removing the pump.

What belt size/length will be required? Can this be pulled from any other BMW application?

 

[cspargo]

Me too!

I'm wondering the correct belt as well - Please somebody who's completed this give up the goods!

Can you takes some pictures to record this process please, along with part (e.g new size of belt) details and any tips for making the job easier. Thank you and good luck.

We've done this on Sebring Sienna , so I'll try to remember to have a look and possibly take some pictures if you are all really nice to me and perhaps send me a 40th birthday card for this weekend !

I'll think about it David but that is not something you want to be reminded of, trust me. h:
BTW the website link in your signature doesn't work. :dunno:

Please recap the benefits of this little removal so I can weigh up the pros and cons.

Cant the bracketry and belts from an M30 be used?

 

[davidoli]

Hallo Bondy ...... 40 is the new 20 !

The benefits are straightforward in terms of less drag on the crank and therefore less BHP drain running 2 bob air pumps !

The website is being converted and revamped at the mo , so it will be out of action for a couple of days before returning with a passion for all things BMW , having the opportunity to add blogs etc etc etc ........

I am currently collecting the various M30 parts to see if it works.... block off plates, A/C bracket and A/C lines from an M30.

 

[davidoli]

We dispensed with the a/c compressor also .

I live in az. I need the ac.

I live in az. I need the ac.

I live for the speed . I don't need the ac .

 

[ss109]

Has anybody determined the proper length belt to power the AC when removing the air pump?

 

[gtopaul]

NAPA 4L330 belt works great.

 

[cspargo]

4L330 is too big for my '91. Stay tuned.

 

[cspargo]

4L330 too big, 4L325 seems to small.

Has anybody really made this work? the 330 allows lots of looseness, and the belt slips easily on the compressor pump clutch.

 

[gtopaul]

4L330 is too big for my '91. Stay tuned.

Don't know why it didn't work on your 91. The belt was installed on my sons Calypso Red 93 and it worked fine. I think they both have the same equipment.

I used a 33" long, 1/2" wide belt to delete my air pump.

I bought the M30 A/c compressor bracket and tensioner as well, but the belt hasn't slipped, so I haven't bothered.

 

[cspargo]

Apparently the Gates 33" belt I had on there (a 4L330 "equivalent") wasn't quite equivalent enough.

I put an actual NAPA 4L330 on there, and it's SLIGHTLY loose, but works like a charm.

Thanks for the input everybody! I'm really happy to have air conditioning again.
