MCI DL3 Trying to keep my cool - Blissfield Mfg HGB 1000 compressor replacement

[plyonsMC9]

Hi bus folks!!

After completely having our a/c dash driver system converted to R134A, the Blissfield a/c compressor gave up the ghost.  Red dye test shows leaking out of about every seal, and then some.

I'd like to just replace that unit with a compressor that fits w/o too much modification, and is a R134a unit.  From what I can tell Blissfield is no longer manufacturing that compressor and doesn't have replacements.

Are there suggested replacement units?  I had done an Internet search a few months back and thought I found a site with replacments, but somehow not finding it in my bookmarks.

Here are some numbers off the plate:
Blissfield Mfg
HGB 1000 compressor
B.M. No. 99242-5

It's ONLY for the driver area.  So it's a small over-the-road unit.  But it's real handy to have available.

Suggestions are greatly appreciated.  Thank you!
Phil

Have you looked at https://truckerac.com yet?

I got my compressor from them a few years ago. Nice people to work with.

 Try 4 states truck parts that is the same compressor used on some KW and Peterbuilt trucks,4 states should have a replacement for the Blissfield

Gentlemen!, I'm greatly encouraged by your suggestions.  Thank you both!  I have renewed hope now on this project.   
I'd been striking out for a while so far.

Kind Regards, Phil

Check out Red Dot. They have been making commercial AC components for years

Phil -

You might consider replacing your failed Blissfield A/C compressor with either a Sanden, Denso, or UAC unit. These are the most common and more efficient compressors in the automotive field, one should work fine for just driver's A/C in a coach. A good shop should be able to cross-reference the Blissfield to one of these other brands to size it properly.

Obviously, some new brackets may be required, but what on a bus doesn't need modifications now and then?

FWIW & HTH. . .

The old York type compressor is still used today they been around since the 50's and they seem to move the freon over a distance better than a rotary type

My vote would be for the Sanden compressor as well, I have used many on auto AC installs over the years and have one on my MC8 for the dash air, all have served well. There are ready made brackets out there that bolt to the York compressor mount allowing you to mount the Sanden, making the swap easy.

My vote would be for the Sanden compressor as well. The old York style compressors never handled the higher pressure and operating temps that the R134 brings to the table in my experience. There are ready made brackets out there to make the swap from York to the Sanden very easy.

Did Blissfield use the same mounts as the York?

Did Blissfield use the same mounts as the York?

They use same mounting that compressor has lager pulley I doubt you can find on Sanden,the engine rpm and the compressor need to matched,Our Lexus when we had a new Sanden installed now throws a code that compressor and engine rpms are off got get it repaired before summer

Great information gentlemen!

I'll be on the phone today and what you've provided is a huge help.

Thank you!!, Phil

Having some challenges -   

4StateTrucks had nothing to replace the compressor with.

TruckerAC has maybe a possibility, from their tech:  "The Blissfield compressors are NLA, but replaced by the TCCI'S. This should be either 03-3004E (OEM), or 03-3304 (Professional grade aftermarket). A lot of those old single groove clutches are obsolete, NLA. You'll have to get the mounting distance measurement and belt size. It looks like a ¾" belt, and if the mounting distance is 2", part number would be 02-3015. If it's possibly a 5/8" belt with a 2 ¾" mounting distance it would be part # 02-3014.

I Will also reach out to Red Dot in just a bit.

Has anyone had experience w/ TCCI? 
Also, would someone please school me on how to get the "mounting distance"?

Thank you!!
Phil

In case anyone is following up looking for a reference, the A/C compressor mounting distance how-to-measure is attached.

consider a  GM A6 compressor. used on GMC 4108 and 4905 and on 10's of millions of past GM vehicles since the 50's.
