Group:
I have been working on tracking the Onan Parts for my CCKA MS/2803J SN H750 970257.
Brian sent me the Case parts list manual. Mike of Onan Parts also sent me an Onan Parts Manual (#927-0253-6-86(Special A-J) Replaces 6-81 (Spe A-J) but it does not cover my Onan serial number.
I am trying to track down the Parts Manual for Onan engine SN H750 970257 so I can cross reference to actual Onan part number. I primarily need entire Case Part C 22551, Air Cleaner Assembly. My tractor is 646-76 SN 9732149.

Does anyone have the right Onan parts manual for my SN they could E mail?

Thank you.

Hi Randy and Ted: Thanks for the posts. I tried Brian and Boomer for the parts first. There are two different air cleaner assembly types in the Onan manual Mike sent. They are both different than the Case Parts manual. So I want to see if I can go with one of the Onan ones unless something comes up on E Bay. Mike does have an older one that might fit my engine. I PM'd Boomer as recommended.
I am really pissed that this tractor was mutilated like this.

In the meantime I drained the "brown", fuel and cleaned the breather element with a solvent, replaced the fuel filter and put in my gas mix of Marvel Mystery Oil/Stabil. I also rerouted the gas line off of the exhaust pipe and tied the fuel pump in a secure position away from the spinning cooling fins of the engine. Dangerous setup it was. I also ordered an operators manual from Brian.
I am going to change the fluids next to genuine Kohler straight 30 oil and 20 40 or 20 50 Rotella for hydraulics. Looks like the bucket has to be up to change the oil filter.

Believe it or not :lol: but Tom has posted a rather detailed process for changing hyd oil on loader equipped tractors.
It`s on the 2nd page of the FAQ section
You might want to chk it out

Just a thought, Did you ever contact the PO to see if he had any parts laying around. It looks like he was the type that if it ran without it to hell with it. Also I notice that your unit is missing the air cleaner baffle, C21547. If you need any measurements on the parts your missing let me know, the 646 I bought seems to have all the baffles and etc on it.

He thinks of everything doesn't he? :sidelaugh: :sidelaugh:

Here it is. The info that pertains to your tractor is about 2/3 of the way down.

Randy/Charles: Thank you. I looked through many of FAQs when they were posted. Tom must have only been getting 3 hours sleep a night when he did all of those, a lot of work . Much appreciated, all the work that went into those.

Ted: I would have to go back one PO. I suspect they bootlegged for a generator or something. Maybe I'll try. Thanks for the offer on measurements, I may take you up on it or even a photo of what it should look like under the hood.

Rich,

If you can't find the specific air cleaner housing you want I think you could easily adapt one of the more common ones by simply making a short tube to fit on the carb housing and weld it to a standard air cleaner housing.

Rotella does not produce 20W50 but any well known brand name will be perfectly fine. Rotella does have straight 30W if you want to use that. It will also work in your engines and it is less expensive than the oil that Kohler gets put into cans with their name on it. Hint, hint. Nudge, nudge.

I am trying to interpret the Onan parts manual. I think I may have found the part number for the air cleaner, for Spec "J", its in red. Does anyone think this is correct?

Onan engine SN H750 970257 so I can cross reference to actual Onan part number. I primarily need entire Case Part C 22551, Air Cleaner Assembly. My tractor is 646-76 SN 9732149.

I had the pleasure of talking with Boomer on the phone today. He is as much a gentleman talking on the phone as on line. He is trying to help me with the air filter setup and also with some other issues. So that part I identified is consistent with the description of a NOS Onan kit I have located from a dealer but it is very pricey. I also located an oil bath air filter housing which is not right for my tractor. Confirmed with Boomer that carburetor vent assembly (funny box thing added by Case, not a Onan part) is connected to the breather when it should be connected to the carburetor. We also talked about what we believe is a second dipstick on this tractor which is accessible from the outside without lifting the hood. It is plumbed into the oil fill/dipstick. With regards to the breather, based on Boomers recommendation I am going to try to locktite it in.
So Case changed things a little with on this engine with that carburetor vent assembly and the air filter housing.

I was wondering if Ted or someone with a 1976 646 with CCKA could take a top shot and two side shots of the engine so Boomer and I can see the air filter assembly, that side dipstick, etc.

I attached the rod to the carburetor today with a little collar doohickey with Allen screw (it helps to be actually connected and not flying off causing the engine to race uncontrollably) LOL. I charged the battery and reinstalled. She fired right way and is now running smooth with the fresh fuel with additives. I also played around with the bucket. Everything works nicely. I can't wait to do some landscaping work with this FEL.

Rich, as we discussed briefly, Salem Power can supply the new, available Onan parts.

That air cleaner assembly crosses to a Onan 140-1308, which is no longer available new (and would be pricey). The components (lid, base, etc) are also no longer listed.

Wish we could do more to help immediately ... but used or from another application seems to be the best route ...

Be Happy to send some pictures if I can ever figure how to load them. Yes I did print out the instruction, just haven't downloaded any of the programs needed. Computer and I don't get along real good, I hate it when some one tells me what to do, and a machine is worse. :sidelaugh: :sidelaugh:

Parts catalog B1302
page 4
shows air cleaner assy. and connecting parts
page 18 item 23
This explain where fuel pump gets vacuum (what you calling outside dipstick tube not)
Gator: Thank you. I can't get the air cleaner filter assembly from Ingersoll so that's why I am cross referencing to Onan parts manual. The Case set up is a little different than what is available from Onan for the CCKA but if the Case setup comes up used or NOS on E Bay I would grab it. What I call the second "dipstick" or where fuel pump gets vacuum on mine is completely different then what is shown in parts manual. Mine doesn't go to base oil block but is plumbed into the side of the oil fill tube.

On your engine as per first photos you ask what is this tube that where hose connects that goes to vacuum pump not from carburetor vent block your vent block in photo in wrong place.

Vent block is correctly to be mounted to carburetor as on page 4 not into crankcase breather.

Allow diagram on page 4 to take over setup on your tractor.
