RD4 Questions/ parts help

I have a RD4 motor with that same set up though I haven't taken the filter tower apart, what is the serial number of your tractor? I'm assuming your tractor has been fitted with a later Fuel Filter Group 5B9914 that allowed for four woven filters to be used instead of the 2 original brass ones. My RD4 Parts Number Book says that filter tower uses a 7B0019 Element Assembly which will have 4 filters, and new gaskets for the tower top.

Try and scrub and flush out that sludge as best you can, that is normal for a working tractor with a lot of hours, you will need to clean your oil screen too I expect, and my suggestion is plan on draining your new oil and cleaning the filters again after a hours good work out, because you will be giving that motor a real good internal clean.

The number tag on the engine is 4G 2138. The tag on the rear by the draw bar is missing. The part number on the filter housing is 5B9720. So when it was modified to take the 4 filters they removed the two brass filters? Is the 7B0019 filter number still available? I need to get 4 replacement filters for this tractor.

I did remove the oil pick up screen, cleaned and reinstalled it with a new gasket. My dad tried to clean as much of the sludge out of the oil pan as he could reach. The oil filter is another problem, It is missing the outer brass screen so the paper element is just sitting in the oil filter housing and the oil was just going around it. I need to find a replacement brass screen and paper filter if possible. I am afraid to run it without the oil filter working properly.

Mike, the fuel filter part number 7B0019 evolves into 2A5886, the 4 woven filters cost about $US45 here in Australia from my Cat. Dealer, plus you will need the gaskets 5B9733 and 5B9831 if they are not included in your filter kit, they add another $US15 to the bill here in Oz, but I'm sure your local NAPA store will have them as a aftermarket set too.

As for the oil filter that is a whole different ball game and I'll need one of our more experienced Catheads to chime in like Edb or Old Magnet, because I'm not aware of a paper element being used around the original inner brass filter, I understood there was a upgrade that did away with the brass filters but only after some internal modifications to the oil filter tower to accept a disposable paper element. Sit tight and don't rush these two critical parts of oil and fuel filtration, let's get them right before you fire her up because a busted engine is expensive.

Hey Mike,

Call Dana with Florine Tractor located in Sacramento, Ca. (Actually it's Florine, Ca.) Dana found RD-4 parts for me before. His number is located in the Parts Sticky. As others have said, after running it a few days and working it, service it again, as the new lubricants will flush it out some. Dana should be able to find the parts you need.

I will give Florine Tractor a call for the fuel filters and gaskets. Since it is missing the brass screen and who knows what else do you think I should be looking to replace the whole oil filter assembly?


This is the only pic I have of the oil filter assembly.

That's a good idea Mike, replacing the whole filter tower with a later model one set up for a better filter, because I reckon it might be cheaper than trying to take it back to the original brass screens, and guys over there are scrapping those old D4's all the time, even "Willie" a ACMOC Director sent 3 or 4 old D4's off to China last year and I reckon he said 2 of them were runners.

Put a request in the Buy / Sell section here on ACMOC stipulating the filter tower you are looking to buy must be set up for "modern" oil filters and not the old brass one's, my Parts Number book for my D4 7J built in 1939, just after yours, says the "newer" oil filter tower is part number 7B7775 using a 6B0907 element. The tower you currently have uses 2 brass screens, 5B5984 is the outer brass screen, while 5B5983 is the inner brass screen, you never know, Dana there at Florin might have a new or good secondhand one on the shelf at a good price, I buy a lot of parts there and find them good to deal with.
