Heat Exchanger Identification and Sources

[Rick McClain]

Hi, My heat exchanger has degraded on one end where the cap had buckled and leaked. I am hoping I can get it welded and machined back to spec, but am at Marco Island, FL. and am having problems finding someone that can do the welding and machine work.
     I may have to resort to buying a new or used one with the commensurate time and monetary extensions. I can't even figure out who made this part or find suppliers. Sabre thinks they can get one from England in about 4 to  6 weeks, but I don't want to be stuck here for that long. Someone else quoted me $800 for the housing only...too much.
      This is on a Perkins/Sabre M92   4.236 Liter diesel engine in my CSY44.
I need the following parts, derived from a Sabre Parts PFD :

 Front Cap #33902
 Plug  #33948
 O Ring  #10171   - 2ea.
 Body Casing  #34467

My tube stack seems to be in good condition.

Can anyone help me out with information on the maker, suppliers, machine shop nearby, etc. Even a used one in good condition would work for me. I can't find one anywhere. None of my numbers are similar to any numbers I see on any of the internet sites.

Dave hasn't seen this yet, but we have a 4-154, so I'm not sure he can help much. 

Have you tried calling a Perkins dealer??  I am sure that will be Dave's first bit of advice. 
Here is our list:

I know that Dave has often called one or more of the first 3 with questions like yours.  You can likely email them your picture and get them to help you.

I will try to get Dave to look at this--we've just been really really busy with 2 boats in the yard, and he hasn't had time to get on the internet much.

Anyone else with a similar engine that could help??

Rick,
Talk to Sherry at Trans Atlantic Diesel. They are located in Virgina and are "THE" North American Perkins experts. They have a web site.
If they don't have an answer, no one does.

Thanks Soggy Paws and Jules,
      I had already contacted Transatlantic and several others. TAD was the one that quoted me $800 for the aluminum housing/body. I'm working down the list of links that Soggy Paws sent me. Great resource list.
       Thanks again.

Rick,

Has your engine been retrofitted with the newer header tank/heat ex/exhaust manifold or the older style with seperate heat ex underneath exhaust manifold (like mine..same engine). I calked TAD a month ago. They had 4.236 heat ex IN STOCK  at just under $500

Hi,
     I guess my heat exchanger is original. I gave up trying to find someone to do the work or finding a replacement. I wish I could have posted all the pictures here on the forum so they would be here for good, but there were too many, too large.

      Here's what I did:  http://Photographers1.com/HeatExchanger/

     Thanks to everyone for their help.

Ok...the pics helped. You've been repowered sometime in the past. You've got a Sabre engine. You can try Bowman in England but have a few shots before the call. Parts are horrifically expensive for the newer Perkins/Volvo motors.

Sorry couldn't be of more help.

And damn fine work BTW!

Wow Rick, that's pretty resourceful!!  Dave would be proud of you!!  Thanks for documenting what you did, hope it all holds up under use.

I have "printed" your pictures and description to a PDF file and put it in the Dropbox under "Pictures of CSY Projects".

As a follow-up, I wanted to let everyone know that the deterioration of the heat exchanger, whos tube bundle is made of bronze and housing is made of aluminum, was probably initially caused by the fact that I didn't know there was supposed to be a sacrificial zinc on the engine. In fact, I had been told that there were none and that Perkins doesn't use them. Obviously not true. However, I thought I had looked everywhere on the engine and couldn't find any. I, also, looked in the Perkins parts manual and found none, and no mention of any. Upon being told where to look, on a pipe between the heat exchanger for the engine, which is the one that was being eaten up, and the heat exchanger for the transmission, there was, indeed, one zinc, hidden at the rear of the engine below the air intake. It is merely described as a "plug" in the parts book. All the zinc had dissolved, thus the aluminum housing was the next item on the "less noble" list. I'll be watching my zincs carefully from now on. I don't want to go through this again!
