Universal 5432 & M40 engine information

I finally got around to the loose ends of figuring out the Kubota cross-reference of parts for the Universal 5432 & M40 engines that some of us have. I went through the ringer trying to get parts for a reasonable price when I replaced my 5432. Kubota "the engine" maker and Kubota "the tractor" maker act as if they are two different companies. Kubota "the engine" maker sells their product to companies like Bobcat, Universal, Westerbeke and others, including their own Kubota "the tractor" maker. As such there can be difficulty trying to figure out what your marine engine was installed in terrestrially. You will need to know this as the local Kubota "the tractor" dealer will not be able to just look up your engine. They want to know the tractor model. Once you can speak their language, all the parts you could want are easy to get and 1/4 the price of Westerbeke's "marine" price gouging.

So if you have a 5432 or M40 it is a V1501 Kubota engine. It was installed in Kubota L345 Tractors.

The Illustrated parts list for the L345 tractor is Kubota part number 97898-20530 for $30 (no procedures, just EVERY SINGLE PART NUMBER!)
The coolant pump for the V1501 is Kubota part number 15321-73032 for $121
Gasket for coolant pump is Kubota part number 15439-73430 for $2.20

Also, the Kubota shop manual the V1501, that contains EVERY procedure for rebuilding/servicing is Kubota part number 97897-00661

As a comparison, Torreson Marine gets $454 for the 5432/V1501 coolant pump, and $5 for the gasket. That is the EXACT same parts folks, just with the Westerbeke "marine" premium added on. Completely ridiculous and uncalled for, IMHO. Westerbeke doesn't make the part and likely doesn't even stock it. They slap their packaging on it with their part number and FOUR HUNDRED PERCENT MARKUP ON IT! Makes me sick, Westerbeke should be boycotted by boaters.

So there you go, if you have a 5432/M40 this info should brighten your day! I will extend an open offer that if I can help any 5432/M40 owner by passing on the info in the manuals I will.

Enjoy, RT

Apropos of whatever......
I have seen at least five new Betamarine diesels installed in boats just in our one little moorage in the last several years. Every engine comes with a Kubota parts cross-reference list.
If this success is being repeated all around the continent, it would seem that Westerbeke is truly asleep or truly arrogant.
Of course, if they get into financial trouble, be darned well assured that they will blame it 100% on "the economy" or "Obama"..... :rolleyes:

Sheesh.

How did you track down the tractor model number for that Kubota engine? I may want to do that for my M-18 engine...

The only way I found out what my 5432 was installed in was talking to a guy named Thomas at SouthEast Power Products in Florida. He knew exactly what I had, simply based on description, correctly called it as a V1501 and then provided the needed gasket kits, etc. when I changed engines. I'm guessing he'll know what you have too. A serial number may help out here if you have it. I don't have SouthEasts phone number at hand but I can find it for you if Google doesn't work out for you.

universal - tractor cross reference

How did you track down the tractor model number for that Kubota engine? I may want to do that for my M-18 engine...
Found this table on the internet back when i was working on my engine. Not sure how accurate it is, but the M-18 would cross reference to the Z600 tractor.

I can second the recommendation to contact Thomas at SouthEast Power Products Phone: (954) 979-5899 Fax: (954) 979-4349. He was very helpful in supplying all the OEM parts I needed for a 5432 and at significant savings over any marine suppliers. Make sure you speak to Thomas though, he use to work for Kubota and knows most of the information (engines, parts, etc……) by memory.

Great!

Ha Ha Rob, you're like baby Jesus.... I was just thinking I should get off my can and figure out the kubota water pump number since mine has been weeping a little at the bearing for awhile now. Armed with your previous tractor info I was going to call the local dealers. Now I have a part number! Dude you're the best...

Another subject...Any thoughts about oil level? Ive been keeping my oil level no higher than half on the dipstick.(2 gallons seems to put it about there) E 38 install has the engine pretty well angled down. Ive been meaning to measure the angle to compare with factory recommendations. Im wondering if filling to the full mark (and the dipstick is at the front of the pan) would have the crank shaft in contact with the oil in the pan at the aft end. I had always heard this was bad and could cause problems with the oil foaming? The oil pickup strainer is further back than the dipstick so it should be well submerged when heeling. Havent had any problems so far but curious.

Engine differences and inexpensive Kubota manuals

Rob,
I was able to find the Kubota tractor parts manual and service manual together as a PDF download from http://kubota.servicemanualvault.com/Kubota-L345-Service-Manual.html for under $5. My 1988 (built 1987) E38-200 has the 5432 engine. From all references I see, this would be the V1501 engine which was used in the Kubota L345 tractor. My water pump, however, does not match the diagrams for that tractor, but rather is the one with multiple bolts on a long tongue on the forward side of the engine. This is the one used in the L355 tractor which is based upon a V1702 engine. Do you know if mine is actually a V1501 engine with a different water pump series, or might this be a different engine? I know that there was something about this previously on the forum, but I don't recall where. I remember that there are 3 varieties of the cooling system, and that I would need to count the bolts to order the correct replacement gasket.If you recall where that was posted, please let me know.
Thanks,
Mike Jacker

I was wondering if you could be great assistance to me with help from your manual. I do not have a repair manual in hand and I have ordered one but it will not arrive for two whole weeks and I need rear main oil seal instructions as soon as possible due to sail deadline dates. I have the rear main oil seal retainer off (14-16 bolts) and I am ready to walk the new rear main oil seal into the sleeve of the shaft, but I have no idea how far on this seal gets pressed? I have the spring side facing the engine and I can see a wear color line in the cam shaft of where I am going to assume the old seal spring sets but I am not sure? Any replacement advice you can give me from the repair manual would be GREATLY appreciated :)
