New guy here, looking 4 info

[Mike Schreiber]

Hi, I fix up old stuff and have this Caterpillar/Canadian military gen-set. What I do know about it is; built by OR for "Canadian Arsenals Limited", a "Crown Corporation". It's a basic Cat built genny being connected to "G.W. Crothers Limited" in Toronto (largest Cat dealer in Canada).

Its 9' long, 33" wide, 64" tall, weighs 4950lbs. Shows 00625 hours and i believe it. Its not locked up as i turned the diesel thru using pony flywheel.

Its previous owners after Canadian military were, U.S.Forest Service, Ohio DNR Forest Service. I purchased as result of Government Service Auction. I have knowledge of the Cat and genny part of this machine as i been messing with old cat stuff for 25 years.

How can I find out about its Canadian Military history, markings, location, etc?

1 bite at a time thanks 4 any help.

I think I was just reading about these yesterday when I was going thru some old CFTOs. They were to supply power for the 90mm M1A2 anti aircraft gun or for the 501B radar. I'll confirm when I get home tonight.

In 90mm Gun Mode, would one generator be supplying a full battery with all their ancillaries?

Welcome to the friendly forum Mike,

Nice to see a useful piece of kit with a military history. I wont be any help but like the gen set as a solid unusual piece. Good luck with it.

I think your generator set would be a PU5003 (or a close copy of it) followed by a letter, depending on who made it and what engine is powering it, and who made the generator. If made by GE Corruthers, with a Cat engine, and coupled to one of two different brands of generator, then it is a PU5003A/U (generator by Louis Allis co) or B/U if General electric.



A similar generator powered by a Detroit is a 5003C/U (General electric Generator) or else a 5003 D/U if a FATO engineering co.



I have attached the front cover of the Canadian Forces Technical Order data summary.



I think someone else posted a similar generator to yours on MLU in the past year or two. I remember some discussion about the VAOS number on a Cdn built piece of equipment.

Turns out it wasn't here, but the posting was on the CSC website: https://www.tapatalk.com/groups/cana...an--t8439.html


I see in another photo you listed on the other site, the generator is a Louis Allis Co, so that should make your generator a PU5003A/U.


Aside from the two data summaries, I'm not sure I have any other info on these.

[Mike Schreiber]

WOW!
It is a PU5003A/U (generator by Louis Allis co).
WOW!
I got more questions now than I did b4.

This unit is 1952, is there a older manual?
How do i find this/other manuals?
How do I find this "other" discussion?
Maybe you saw my discussion about it on Canadian soldiers site?
May I use your post on my other "old engine" sites?

Thanks!

If you look near the top of the data summary, it mentions it supersedes the first issue dated 28 Aug 1953. Most often the manuals come after the equipment.



I suspect yours may have been an early one before the PU-5003 designation came out for these sets.


Yes, the earlier discussion I remembered was actually on the Cdn Soldiers Site.



Feel free to use my input on your other sites.



Attached should be the other 3 pages from the data summary.

Thank You!
