That is the same alternator I put on the 4855 with the Yanmar.

I've had the one on my JBI for like 4 years & works great. Sure be glad when my newest one comes in.

I had the shop set it out for 1 wire and it is rated at 35 amps. You can here it on the motor when you run the electric fan.

Yeah, I figured the one on my JB to be 35 amps, but apparently the same alternator comes in different amp capabilities. Until I get my new one in to get the numbers off it, I won't know the amps. 35 amps is MORE than enough, so really, it doesn't matter either way to me. Yep, when I run my little Yanmar that is destined to my loader tractor, it pulls the engine when that fan kicks on too!

It's also big with the stock car drivers around here to reduce weight.

I forgot to take a pic of my CCKB's carb before I altered it, so above is a rep pic to show how the main jet screw is on the bottom of the fuel bowl. I've changed mine to top main adjustment. Kind of gambling, but I have another carb body, so I knew I could always go back to stock design. Anyways, I've seen other CCKB engines with carbs with factory top side main jet adjustment screw, so I knew there had to be a way to do this to my carb. Adjusting the bottom main is nearly impossible with all the heat shields. The problem is, the main also has to serve to get the fuel through it to the top of the carb to supply the idle circuit with fuel. So I used a Kohler carb's main jet adjustment tube to do this. I will follow up with more details & pics later when I have the time, but for now I'll post this video to show it does run with my "on the cheap" system. Hey, I had to try! You can see that she does idle well, and the main does cut off the fuel when I screw it down.

Daniel. Looking forward to you doing permanent carb mod and posting the results. I have a brand new in the box carb that I may do the mod to. Dave.

It will be a while, as I need to pay some garden tractor debt before buying the kit with the proper needle. But I'll be sure to post good pics & details when I do.

Been driving the 620 for a while now, and the engine is running smooth as silk with NO surging at all using this altered carb. So this carb is good as-is, but I will still re-do the spare carb with the proper Onan tube later.
The steering used to wander all over, then I adjusted the toe-in & it improved (had toe-out), but still wandered some. I thought it was a worn front axle pivot bushing, but it turned out the bushing bolt was loose. She drives straight & true now.

Sounds like the shakedown process is coming right along. Do you have any plans for this one. It would make a pretty serious loader tractor given it's weight. Does it have power steering?

No definite plans, other than keeping it! No plans for a loader, as I just don't have the $'s to build another loader, plus the one on my Massey is truly all I need. I will likely till garden with it, and maybe plow some too, but then I love plowing with the diesel JBI Bush Hog. Just another toy I guess.

Good to hear that you're getting the bugs worked out of it. Just throw it on that empty trailer, when it heads this way.

Is there enough room for 2 of them on the empty trailer?

I'll see what I can do Doug! ..........not! :smilewink:

Not much wrenching time today, but did manage to straighten up the oil cooler shrouds, and some of the cooler fins. Also pulled the fuel tank so it can air out before brazing a new fuel outlet line into it. Looks like I might ought to put a tank liner kit in it too, but that will have to wait.
