Gallion 503G ------ Some assembly required

So, I have a new project to work on soon. Picked up a Gallion 503G grader, and a pile of parts that a mechanic said came out from between the engine and transmission.

Have yet to bring it home

Apparently it has been re-powered at some point in time to a 4-53 and the engine didnt line up with the transmission properly or the adapter built was vibrating too much or something.

Long story short the mechanic pulled it apart and called the customer to let him know. Customer didnt want to spend anymore money on this grader.

Made a deal on it the way it is. Mechanic said the 4-53 runs good, and it came with new tires on it.

So I guess I'm looking for any information on what would of been there from factory, pictures of the clutch assembly to compare, any tips and tricks that could help me out, part numbers etc.

Especially any info from someone whos re-powerd one of these.

Even just some pictures of other peoples 503's would be good too. Might keep a smile on my face while pulling out my hair.

Thanks in advance

I know that they came with the International diesel engine, don't recall the model. Also came with a Continental F226 gas engine.

I have no idea what it had in it originally. Grader is SN 5131

This is the spacer someone had between the tranny and the block

And apparently this is what they built to bolt onto the 4-53 flywheel and extend the clutch out. spacer.jpg clutch abortion.jpg

hydraulic pump appears to be driven of the crank of the motor at the back of the grader. Kindof like a cement truck would be off the front.

Probably wont have the grader home for another week or so. Got to find a way to pick up the blade and load it up over the beavertail first.

A Deere 4045 or a 4039 with a SAE 4 flywheel housing and a flat face flywheel is the hot ticket. It came with a F-226 Continental from the factory.

So would this save a lot of work or would I still have to build a lot of adapters and spacers to make the clutch work? I think the way it was there wasn't even a pilot bearing being used

It looked like the last install was about 9.5 to 10" of space between the sae3 on the 4-53 and the sae4 on the tranny. However the engine couldn't be moved towards the tranny much farther due to the oilpan clearance.

Have you ever repowered a 503? would the deere fit forward with the pan? It seems like you know quite a bit from some other posts i ran across.

What would a guy find those deeres in?

Do you have any more info that would help out? It might try checking into finding one of these deere's up here. I was hoping to use the 4-53 just due to cost savings but....

If you get a SAE 4 flywheel housing for the Detroit, along with a flat face flywheel, it’ll go in, if it’s a front sump.
The Deere’s are pretty easy to find, look for trashed air compressors or street sweepers or such.
I’ve done 4 so far, an A with a 4045 Deere, a L with a 4039 Deere, a G with a SD-33T Nissan surplussed by IH for the Scouts, and a 4.236 T Perkins in a AC D with a Galion G transaxle.

The Perkins was a SAE 3 and it fit, but was a pain to get together. We had a SAE 3-4 adapter ring made and the only way to get it together was install the pressure plate and disc loose on the input shaft, bolt up the engine and put the pressure plate on the flywheel through the hand hole.

I can't say that is the most screwed up "A-dapta Kit" I have ever seen, but it's sure as hell a contender. I cannot imagine the vibration if you ever actually assembled that and lit it off.

i thought it looked pretty good the first time. I hadn't waited long enough to see the crankshaft extension pic:D

Yeah, it doesn't look like they put much effort into making sure those two bell housings mated flat and centered?

So. After a day of calling around, I've turned up a possible deere. In a pelican street sweeper. Thinks its a 4039T. Wants $4000.00 Cad. Its a 4.5 hr drive away (got to take the whole sweeper so i would have all accessories) And has no idea on what sae bolt pattern it is.


If the deere is not a sae 4 is it hard to convert and are parts readily avalible? Is it to much for the tranny / axles of the grader? Being that it drives a hydraulic pump on the sweeper I would still need to find a flywheel? and obviously a clutch.

Would either of the SAE 3 to 4 adapters by hayes work to mate the 4-53 sae 3 to the sae 4 transmission ( one is 1 inch or so thick). or would it be a PITA to mate a clutch setup to? would I be able to use a sae 3 flywheel still and make a clutch fit it. From what i saw on the 4-53 i would need to change out the back plate of the motor to go to a sae 4 properly. Also i cannot source one up here.

Not new to working on equipment and rebuilding diesels but never had to rework anything like this. Everything else has been take apart, repair with part numbers and re-assemble. Parts are in a pile for this machine so i didnt even get to take it apart to see how it was.

Dont want to waste alot of money doing it wrong.

Thanks for the info so far.

The #3 on the Detroit can be made to work. You will have to do some very careful measuring of the input shaft on the transaxle and size the thickness of the adapter ring accordingly. Most machine shops can turn out an adapter on a lathe without much drama. The oil pan is the next problem, a front sump or a cut and weld sump is next. A automotive flat face flywheel is needed.
Lastly ditch the through shaft hydraulic drive and run a larger GPM pump off the front of the motor, maybe a double pump to run a full hydrostatic steering setup. To plug the hollow input shaft use a USA nickel as a soft plug to keep the oil in. We always used the current year to know when it was done.

The oilpan is a front sump and it already has the hydraulics running off the crank on the front of the motor currently. It still has the shaft in the tranny though but didnt seem to connect to anything engine side.

Love the nickle idea. However trying to get a usa 2021 nickle up in canada right now just aint gonna fly.

Been missing my trips down to Montana and Idaho. Oh well.

Used to order a Ton of project parts to a friends house in montana and pick them up with the wife and kids ($800 duty exemption each) and what i saved on duty and shipping would pay for a 10 day holiday down there.

Swaying more towards the deere right now.

So according to your measurements I think I would have to call it a SAE 3. It also looks like I would need to get a different flywheel to accept a pressure plate. and find a way to go from SAE 3 to SAE 4 still. Either by an adapter plate or by changing the bellhousing on the deere if it is possible to do.

I wonder if a good machine shop could drill the flywheel to accept a pressure plate?

Thanks for the pics. If i go this way im not shure what i will do with the rest of the parts by I'll keep you in mind when im done with everything (been wanting to build a hydraulic log mill so there might be some more goodies disappearing), lol
