Default 1941 Hobart M5 Generator

I have only just joined the forum (had it recommended to me) and before i start with a request for help....
I live in Leeds in the UK, and collect WW2 US vehicles and equipment. I have 20+ vehicles, (jeeps, Dodges, Halftracks, Diamond T wrecker, D2 Cat, Sherman tank, several trailers, AA gun, many tents and tons of period field equipment) and restore them to represent the men and women of the 702nd Tank Battalion and 80th Infantry Division (see www.thetroubleshooters.com and navigate to Troubleshooters Today to see a bit more about that if it is of interest).
I have recently added an M5 power unit to the fleet, which is in very good condition. I have had it running, but am trying to find a source for a carb gasket kit (for the Schebler TCX39), a replacement float (as mine doesn't really), a spare head gasket and a replacement rotor arm. I have tried to find a supplier on the internet, and whilst it might just be a sign of my inablilty, i can not locate one.
I note that some people on this forum have at least rebuilt their carbs - does anyone know of a source for spare parts (carb or otherwise) for these units?
Thankyou in advance of any assistance.
I should add,i fully intend to use this piece of kit at the public shows we attend, to generate power as it was intended to do. All my kit is functional - at least that is the plan........
Regards
Ken

The carburetors are as rare as hen's teeth, recently one was on ebay's "buy it now" for about $300. I have been passively looking for a float of kit for at least 10 years, I do remember making mine out of a aerosol foam and coating it with "Red Kote" (Por15), its still functioning. Later Hercules ZX manuals referred to the Zenith series 161 carburetor (possible replacement). The M5 units had 4 spare head gaskets attached with screws to the underside of one of the doors on the engine compartment, check you might be lucky.

Thankyou for your reply. The gaskets are not there, i have checked. Looks as if i will have to resort to plan A which was to make a float from some marine cork and coat it in a fuel resistant glue (or POR15).

Ken,
If your float is brass and leaks, you should be able to find & fix the hole. I think my M5 has a brass float.....

I did coat the gas tank with Red Kote, as it was very rusty. This seems to be a problem with these units.

Manuals can be bought from various sources, do a search on the message base here for other threads on the M5.

My carb seemed to run a bit rich, so I machined up an adjustment screw/needle and fitting with packing (an 'O' ring) to replace the plug on the bottom of the carb. It worked out well, and cut the fuel consumption by a bunch. Downside is that you have to fool with the choke for a couple of minutes to keep it running while warming up.

Oil Filter is a Fram C3 or NAPA 1010. I moved my filter assy. towards the front so I could change the filter. Before, it hit the edge of the hood.

Mine generally attends 2 antique tractor/engine shows each Summer and attracts a fair bit of attention.

Thankyou for your note. I have the manual and the wiring diagram, which came with the set. My float is cork, i was actually thinking of having a go at making a brass one today, in an idle moment - you might have just pushed me over the edge in to having a go at it. The rotor arm is also a pressing need. The parts are out there somewhere, i need to find them. I have spent 6 years looking for the parts for my Ford GP and 3 years collecting parts for the sherman, so the M5 has a way to go yet.
Regards
Ken

ZX head gaskets and gasket sets are available. The zx had a variety of small zenith carbs depending on the application. Floats are also probably available although I have not looked for any. There are a few people that overhaul these small carbs.

Ken:

If you're referring to the rotor arm of the ignition distributor, you might be able to find something close enough to be able to modify.

I remember years ago getting a Hupmobile going. Someone had taken the rotor and I couldn't find one in any local auto parts store.

I had some old rotors that had been replaced but were too good to simply throw away and found one that fit perfectly on the distributor shaft but the metal tip wasn't long enough to reach the plug towers. A bit of copper and a good solder joint fixed it fine and the car is probably still running with it.

Be ingenious!

Take care - Elden

Thankyou - again for the messages and support.
I have had to be ingenious and use a piece of sprung steel from a set of old points to make a centre contact for the ingition (distributor) rotor arm, but would like to find a 'proper' one if i can.

When you say that the floats and carb gasket kits are available, can anyone point me in the right direction? I am still searching, but so far to no avail.

Regards

Ken

Contact the man in post #7. It seems he has or can get what you want.

I just wanted to say thankyou to all who have replied to my post. I now have more headgaskets than i could ever need (from Estonia of all places), two spare sets of ignition points, rotor arms and condensors, a replacement float and two carb gasket sets en route to the workshop.
Hopefully, at some point in the future i can return the kindness to members of the forum. In the meantime, i hope you get some satisfaction in knowing that through your help, another piece of WW2 US machinery is still capable of doing what it was designed and built for - and is indeed still 'doing it'.
With best regards from the UK.
Ken

I know this is an old post but I found one of the m5 generators today. It's been sitting out for a long time. I will get it in the shop next week ..I hope.

you are missing the generator to charge the 6 volt starting battery.these sets are negitive ground. most old 6 volt equipment is positive ground but the military has to be different. let me know if i can help you get this going . i have a m5 that i restored and use to have power in my shop.

Thanks for the information. I have not looked at this too closely yet. The unit was left on some property that my family owns and has been sitting for 20 yrs. I will check it out next weekend and it will be up for sale eventually.

I know this is an old topic but does anyone have any original voltage or load current gauges for a 1942 Hobart M5 generator they would be willing to part with...If not pictures would be a huge help

Thanks Luke

I have a 1943 M5 by Minneapolis Moline. I was going over it in anticipation of using it in the event we lost power due to hurricane Irma. I finally got around to rebuilding the carb with parts I purchased in 2013 and found it to be running on the rich side. I recalled reading in this thread about adding a needle adjustment screw into the main jet through the float bowl securing screw. Can anyone supply more details in making this modification.
