Default Gaseous Onan JC in the future?

Talking with my wife's uncle in southern IL this morning on the phone. He called to ensure I'd be around the area over the Thanksgiving break. Says he has a four cylinder, air cooled and propane fueled generator with switch gear he's acquired for me. It is green in color with an "Onan" logo on it. No other specifics at this time.

I understand they tore down an old milking barn to sell the exterior wood and this set was installed but no longer needed. Also said it was running as they were using it for power till they took the barn down earlier this year and he brought it back to his machine shed.

Being an old time retired machinist from Caterpillar, he's one of the types that makes the rounds during the day first going to the coffee shop, then another restaurant, then someplace else daily, etc..... so not surprised he'd run across most anything while solving the world's problems at the "liars bench". Last year I built/welded up a new burner chamber for his "Clayton" wood burner/stove which is used exclusively to heat his house and shop but wouldn't take any $$$ for it. This year I furnished new cast iron "shaker" grates for it. I figure the man has done far too many repairing/rebuilding jobs for the family in years past to ask for compensation; I'm thinking this generator may be something along the lines of paying me back knowing I won't turn it down.

84 years old and still a conniver at heart.....

Most common is the four cylinder JC. !2.5 or the !5 KW.

He's a good guy, really is and nobody minds helping him out when the need arises.

I was thinking the "JC" series is four cylinder which this is, and the "JB" was two? Never had either so certainly no expert however.

Thanks,

Correct! JC is 4 cylinder and JB is a 2 cylinder!

If it's a JC, then it's one heavy beast. Lots of iron in that baby. I used an engine crane to get mine off the ground and a trailer to tout it home. Manual lists it in at 682lbs.

He will just pick it up and toss in the trunk of a prius or roof of a smart car. LOL

Yup. I'll just throw it up on my shoulder much the same as I did the boulders at the end of the driveway which are probably a bit more than what the "JC" weighs.....

In reality I have a hydraulic crane mounted to the truck that should pick it up and swing it around. I have a DJC, and have a generator end off another which was originally from a blown JC. Just haven't been able to get a good engine for it yet. Couple of prospects have not worked out but I really want a NG fueled unit installed onto the house permanent. This one being on LP gas should be easily converted.

Ahh a truck with a crane and swing ability. Must have a service truck, possibly a medium duty series. I drive a Medium Duty Topkick with custom bed as a daily driver. My Onan lives up near the bulkhead of the bed. Under a cover of course.

JB is ~ 450 #, was a lot of work for the 2 of us to "walk" it with 2x4s from trailer to trailer. Even though trailer heights were identical, level , and butt to butt.

I constructed a dolly just to move my JC off the trailer and onto the shed floor. Had to use an engine hoist to get her high enough to put the dolly under her.

I have a 1957 Mack B-61 which is kind of a service truck but more of a mobile welding rig. It has a LeLand "Roustabout" bed with fold down poles and rolling tailboard. I cut the truck in half, rerailed the rear half and utilized a Peterbilt "Air Leaf" air suspension from a 359 Peterbilt after a complete rebuild to everything. It rides a lot better than the former spring ride but is still "stiff". I'm hoping to get it somewhat complete over this winter after work winds down. I don't have a dedicated generator permanently mounted as usually just use the welder power for jobsite work. I do plan to install something but haven't decided yet. This truck sure has pulled and set a lot of generators for work. I can pick 3500# straight out with the hydraulic crane after setting the "stiff leg", raise the load straight up and swing it to set in the center of the deck. Works pretty good but I'm in the works, (planning at least) to convert this truck which is a bit longer to a service truck with a full bed. Got to get retired from the federal job first which is winding down and I'm two years eligible for retirement.

It currently does yes. Double overdriven, (TRT-7220) running through 3.70 gears on 10.00X22 rubber. Will run right to triple digits, but not enough power to hold there. Original END-673 engine which is either 170, or 180hp non turbo Mack diesel, (I can't remember). One of my other B-61 trucks has a turbo 711 engine and it has quite a bit more power. That one has a double over quadraplex, (TRQ-7220). Nice smooth transmissions once you get the hang of them.

Non turbo Mack Diesel? I bet that has a really clean exhaust output!

Only when I don't drive it..... It still smokes like a good, well tuned diesel under load does yes. Remember the days of old when semi trailers were painted down the side with exhaust soot? Yup, I got that still.

Prius drivers love me.

15.0 JC looks very close to new as in above average condition. Durango is not large enough to haul it home this trip.
