Universal to Kubota Parts list?

Has anyone found a good reference to cross reference these things? I've got a m4-30 (for the time being) and it seems like something that people keep talking about, but the GOOGLE can't seem to find it.

The M4-30 Universal engine is the Kubota V850 engine serial#08510. It was sold to Westerbeke along with all rights, parts, etc. Kubota dealers can not locate parts for this engine. I require 4 injectors which are sold by Westerbeke at $470+/- each while other Kubota engine injectors are listed at $45-$85 each. Does anyone know where we can cross reference Westerbeke and Kubota parts or locate description/specifications for Westerbeke parts that can be used to identify potential Kubota replacement parts?

Power For Sale,
I have an M4-30 Universal engine made by Kubota for Westerbeke. The engine model # located under the injector pump is V850-176248 and the serial #08510. I need 4 injectors. The current injectors are Nissan Denso 3340 7J and according to Westerbeke part #302735. Can you help?

see my post earlier in this thread. Westerbeake/Universal used these injectors across most of their product lines.

From my other post on SailNet;
There used to be a document titled History of the Universal Motor Company in numerous places on the web... It seems to have been deleted from most locations (I wonder why).

Here are the salient points:

First Universal diesel: 5416, it was a 45 cu in, 16 hp, 2 cylinder, based on the Kubota Z-751 block and built from 1976 to 1982. Evolved into the Model M20, which was produced in 1982 and 1983.

5411 was a 31 cu in, 11 hp 2 cylinder raw water cooled diesel, based on the Kubota Z-500 block. Built from 1977 to 1982. Replaced by the Model M15, which was produced in 1982 and 1983.

The Model 5424, was a 68 cu in, 24 hp, 3 cylinder, based on the Kubota D-1101 block. Built from 1977 to 1983. Replaced by the Model M-30, which was produced from 1983 to 1987. The Model M-30 was the same size, but later M-30 engines were based on the Kubota D-1102 block. It was built from 1983 to 1987.

Universal 5421, a 52 cu in, 21 hp, 3 cylinder, based on Kubota D-850 block. Built from 1978 to 1981. Replaced by the Model M25, which was produced from 1981 to 1986. Replaced by the Model M-25XP, a 57 cu in, 23 hp, 3 cylinder, based on the Kubota D-950 block, built from 1986 to 1999.

5432, a 91 cu in, 32 hp, 4 cylinder, based on the Kubota V-1501 block, was built from 1978 to 1982. Also called the Atomic diesel. Replaced by the Model M40, which was produced from 1982 to 1998. The Model M-40 was also a 4 cylinder model, and the same size at 91 cu in and 32 hp but it was based on the Kubota V-1502 block.

Model 5444, a 115 cu in, 44 hp, 4 cylinder, based on the Kubota V-1902 block, was built from 1980 to 1982. Replaced by the Model M50, which was built from 1982 to 1997.

M-12, a 24.4 cu in, 10 hp, 2 cylinder based on the Kubota Z-400 block, was built from 1983 to 1988.

M-18, a 34.8 cu in, 14 hp @ 3,200 rpm, 2 cylinder, based on the Kubota Z-600 block, was built from 1983 to 1988.

Model M2-12, a 26 cu in, 11 hp, 2 cylinder, based on the Kubota Z-430 block, was built from 1987 to 1997.

M-35, a 75.5 cu in, 30 hp, 4 cylinder, based on the Kubota V-1200 block, was built from 1987 to 1997.

M-35A, a 4 cylinder engine producing 22.3 kW / 30 hp at 3,200 rpm - details unknown

M3-20, a 38.9 cu in, 18 hp, 3 cylinder, based on the Kubota D-640 block, was built from 1988 to 1997.

M3-20A, a 3 cylinder engine producing 13.4 kW / 18 hp at 3,600 rpm - details unknown

M4-30, also called the Atomic Four diesel, a 52 cu in, 25 hp, 4 cylinder, based on the Kubota Y-850 block, was built from 1988 to 1997. Offered as a diesel replacement for the original Atomic Four gasoline engine. It was similar to its namesake, since it was a 4 cylinder model weighing slightly less (122 kg / 270 lb as opposed to the original's 150 kg / 330 lb with reduction drive - the M4-30 was only offered with a reduction drive) and generating slightly less power (18.6 kW / 25 hp at 3,600 rpm as opposed to the original's 22 kW / 30 hp at 3,500 rpm) with a smaller displacement (850 cc / 52 cu in as opposed to the original's 1,065 cc / 65 cu in).
I believe (90% sure) that all of these engines use the same injectors... My earlier post referenced an injector that cross references to Kubota Part Numbers; 15221-53000, 15271-53002, 19202-53020, 19202-53021, 70000-65208

However, it's YOUR engine. You should do the research and get to know this stuff.

Re: Universal to Kubota Parts list?

--------------------------------------------------------------------------------

I found the Kubota equivalent for my 5411 which is the Z-500 [check the dipstick, it should have the Kubota engine # imprinted on it] then a call to my local Kubota dealer resulted in a fax from him of the entire engine chapter of his parts book. I have it in my binder next to my 5411 manual as a cross reference

Would you be able to share the info you have on the 5411, It would be great information to have,

PM me if you wish

Thanks
David

Stupid sailnet living in the stone age, limits attachments to teeny tiny little bmps and jpgs and NO pdfs.....whah!

If anyone wants a copy of the Kubota catalog for the Z500 (aka Universal 5411) showing parts and numbers to save big $$$ at your tractor dealer drop me a line and I'll email you a copy. It's pretty small, about 500k.

Hi to all Members out there, I'm Rick, new to the forum and eager to learn and contribute in all ways possible.
I have a Pearson 35 with a 5424 that doesn't want to start. I bled after the fuel filter and before the injector pump, getting the air and fuel out of them. Then I cranked and used the release to try to start without success. How could I test the pump or what could have gone bad? Does someone have an good diagram of the pump, someone told me it seemed like if a key could have shattered and to pull it out, ?.
Blowinstink, Ishmael, could you share with me the info on the 5424 you mentioned you had on 2007?

Hello guys, my motor is running again. I had to use another tank to start it since there was no access to the tank and I couldn't clean it, yet. I bled at two bleeding spots and sprayed a little ether into the intake and it fired right up. It then started easily several times so I think it'll be ok. The gauge reads 670 hrs, too good to be true but I hope they are real.
I am going to need some help though with my transmission. I've ran it dry. I've had this sailboat for more than a year but when I brought it home I motored it 60 miles flawlessly. I then took it for a sail a couple times and motored it a bit. Finally I forced it in reverse when trying to set a three way anchor setup and stopped the motor only to find the shifter frozen the next time I went to move it. I can only shift hammering the shifter at the transmission. It will move forward and reverse only when hammering fron the transmission, the remote shifter by the wheel isn't able to shift. I am planning to remove the motor to get to the transmission so I can take a lloik inside and see what is wrong. Is there any information on these transmission, will I be able to get parts for it?
I haven't been able to find any info on the tranny. Do you know anything about them?
Thanks again for the help!!!

Your 5411 is a Kubota z500 block. It was used in their B5100D and B5100E tractors. Still haven't gotten around to rebuilding mine, but last February I received a quote from Sid at Kumar Bros (www.kumarbrosusa.com) for bearings, pistons, etc... basically a rebuild kit minus gaskets... for $259 with free shipping. At that time everything was in stock. Hope this is helpful. Keep us all posted as you go along with this! Mine is still out there on my project list.

Ok. Sorry i do see the z500 on the dipstick. I thought i was going to see a cereal number. The kubota dealers wont help me without it and i cant see it anywhere. All The labels are worn off and i dont see any numbers embroidered on the actual block other than the 508 cc. Most threads ive read people say they see the cereal number on the side of the block but i dont see it.
I was able to get a rebuilt block to replace the frozen one that i pulled out of my boat and right now im piecing together the parts that are salvageable. The original block im still working on unsiezing. The conrods are in a position where i cant unbolt them to beat the pistons out without turning the crankcase which doesnt seem to be going anywhere. Not sure its worth saving.

JJJ sometimes it takes the heating and bending a 12 point box wrench to get at the cap bolt ends. but it can be done.Get all the caps off and carefully lift the entire crank.The con rod bolts can damage the journals. Then tap each rod.Watch for ridge wear at bore top before you damage the ring lands Worth saving ?? your call but giving up ???
