i recently bought a 1944 peterbilt with a 150 cummins. it has the single or double disk pump (i dont no how to tell the difference). anyways this truck has sat for 23 years, im looking for some info on priming this pump and how to lubricate the disk(s). and any info that would help explain this pump so i atleast have a basic understanding. ive worked on a few cummins but nothing with this pump. any help would be great!

Thanks Ryan

Ryan, I brought a thread back to the front regarding Double Disc pumps which contains pictures.  I hope it helps identify your pump.

thanks eddy i looked through that post got some good info. hopefully i can get the engine running. as it is now the engine is locked up so i have some work ahead of me. but i also have the option of swapping the engine for a 262 with jakes and a t590 that i could get. the only thing is i wanted to keep the truck as original as i can. as i understand it a h600 672 and a 743 block 262 would be pretty simialer in length right? isnt the 743 just a punched out 672? only difference would be width (turbo) and slightly taller because of the jakes.  my h600 was turned up to a 185 in 1952 and has 4 valve heads on it.

Shoot Stephen Paul an email @

He has done some work on single discs and should be able to help.

The 262 will fit, you'll need to adapt a different front motor mount to do it, the rear mounts stay the same, I don't know if the 590 will fit, I can do some measuring and see, I have a 47 with a 280 in it, but running a late model Holset, but I have  a 262 with  a 590 on it and I can check between the two of them, if you can see what the front trunion mount looks like, and how its fastened to the frame.

thank you Dennis Wells AKA Smiley, ive been into old trucks for a few years now and just bought my first one to restore, im really excited to start working on it. Forgottenhighway thank you i am going to email him when i get done posting this. and aaron ill have to look at it. id really like to keep the original engine but if i can get it free'd up ill get that 262, now that i think about it he also has a 220 which would probably be easier to fit.
