I never saw one either, but keep in mind all blowers were not necessarily used on engines, some were just industrial applications.
What was that small blower they put on those little diesel generators - a 241 or what ? Dam if I wasn't at an auction years back.....there was a little generator with a little blower...couldn't stay....and stuff was going cheap.....my timings always off......
Old br*** plate like that seems at least as old as the 40's. Probably not Japanese with English characters on the plate.
Very cool blower, wish I knew what it is and what it was used for. I am guessing a industrial application .
looks like a Detroit 53 series blower with some odd end plates. Several different sizes and variants were made. Most likely out of a marine or industrial application...
It's standard. All of the bearings are "made in USA" and all of the casting numbers are in English Sent from my HTC6525LVW using The H.A.M.B. mobile app
This is a handsome little blower and I'm quite surprised that more people haven't replied with information. I like the way the bolting lugs continue up the housing. Has a considerably beefier appearance than most of the common blowers. Surprised this design hasn't been incorporated into modern racing superchargers. Curious what the overall dimensions are compared to the GMC 471 and 671 cases, as well as the bolt spacings.
The -53 series blower mounts with bolts through the end plates but the one pictured by the OP has mounting lugs on the case, I still believe it's industrial. There was also a short lived -51 series engine and those blowers mounted like the -53's.
Intriguing.....I once re-purposed a military surplus roots for a small displacement engine. Anyway a couple of clues as to its origin will help in re-purposing. I would say it was an industrial origin except that it has square mounting flanges. The manufactures of industrial units that I'm familiar with use standard round pipe flanges and this would seem to indicate it was for a specific application. The drive end would appear to only have a single bearing and might have been close coupled as opposed to tangential loading. As far as applying to an engine, Steel vs aluminum rotors would also be a clue . I would rather have aluminum rotors rather than steel if pumping fuel/air at rpm. My surplus Sutorbilt had a similar reservoir in the back and zirks on the front and probably designed for direct coupling and low rpm. The case and rotor volume will be eventually helpful for rpm vs cfm. I really like the mounting flanges and looks like it could be a fun project.
The drive is a bolt on double v belt pulley "that I didn't get with it, with a self-contained ider. The rotors are steel. Sent from my HTC6525LVW using The H.A.M.B. mobile app
A possible other source...in the immediate postwar surplus ads in the back of magazines like Popular Mechanics, there are roots blowers whose job had to do with pressurized cabins in aircraft. The pictures I remember were small and crude, not really helpful. Pressurized planes were just beginning to be important in WWII...I think the B29 used pressure.
Seeing you are in SD, I'm reminded of a story told by my friends older brother about 1967. He was in the Navy and claimed he saw a pallet of new GMC 671 blowers being dumped into San Diego Bay. I will never forget hearing this story.
"Seeing you are in SD, I'm reminded of a story told by my friends older brother about 1967.

People were suppose to dump their tool boxes, etc. I never actually saw anything being tossed and the tools I collected over time were special to me. I actually worked 34 yrs at a chemical plant on the bay next door to a Navy repair facility and 32nd street, but that wasn't until 1972
Hopefully it will be good for few pounds of boost on a 276 Flathead. Sent from my HTC6525LVW using The H.A.M.B. mobile app
ok...going thru my industrial catalogs........maybe not it.....GMC had a little 4cyl with a blower....series 51 ?
The 51 one series blowers are similar but are not a match. The 51's mount via four bolts in the bearing plates. Sent from my HTC6525LVW using The H.A.M.B. mobile app
