well a while ago i got a FREE p pump. yes free. 130k on it. but......its from a 190hp@2800rpm mercedes 352A. well here are a few pics of the pump. on the bosch Merc pumps the lift pump is driven by the IP, but that'll get a block off plate. it uses the same mounting (or so it looks like) as 94-98 12v's but with a twist. it has a key way shaft which a 1st gen gear fits perfectly on, so far that i kno of. i have the merc pumps gear mounted on a 4bt pump in tinkering with and it fits great. but im going to mess with it and see how easy it is to turn up and etc. its worth a shot i guess lol

heres some pics.

Interesting project!

 

thanks wanna, ill keep updates as i go, i need to get my 24v goin again before i can tear into "All Spooled Up" lol

 

hmm thats pretty cool. might keep this in mind for a later on project...

 

Hate to be the guy that pop's your bubble, but that's not a P-pump, its either and A or a MW. I know the A has a slightly smaller pilot hole and bolt pattern than a P, it enough to make it a pain, I know you can get a bushing made for the hole and drill and tap new mounting holes for it, at least thats what we do with the John Deere engines that have the P-pump hole in them. Not sure if the MW shares dimensions with the A or the P.

As far as the key in the shaft, P-pumps have key ways too. If the first gen gear is fitting on it definitely smaller than a P-pump.

I got more bad news too, if that VE pump I saw as your last picture is the one your talking about it is not off a 4BT Cummins. The flange side has that extra length and the timing advance is on the wrong side. Don' know what application it is for.

 

it was off of a 4bt cummins that was a case gen set. the pump was on the pass side like the merc pump which is opposite of the norm cummins pumps but it was infact a 4bt. i kno cause i took it apart when the block cracked, mounting the merc pump wont be a problem then.


p.s. so u kno the cc specs of this inline pump?
and its an A model pump.
i decoded the tag under the aneriod
R-flyweight gov.
Q-fulcrum level model
V-variable speed governing
300 low speed rpm (600 idle speed)
1400 high rpm (2800 rpm engine speed)
AB- model

 

Post the number on the tag that is under the last delivery valves, I don't know the CC's, but I might be able to decipher the plunger diameter, the smaller ones aren't worth fooling with sometimes. Do you know the rotation direction of the pump? And how big was the engine in came off of? Does it have is own lube oil or is it fed from the engine?

As far as mounting, you would need to start out with a P-pump front gear case, but I would look into a 24 VP-44 one as well, that might work too. You'll also need a set of injection lines made up with the correct threads on each end.

I'd love to have seen an picture of the engine the other pump came off of.

 

it looks like

908 Bosch
(number stamped) 549 8853
(under the stamped number printed on tag)PES 6A 410RS 2596.

as for pictures of the engine, theres 6 of them at work which is where i got the pump, right off the shelf. ill post a few tonight after work. no engine oil lube system, i think it just might use fuel to lube it, also the pump rotates the same direction as a normal cummins pump

 

From what I remember of Bosch nomenclature, I hope that doesn't mean it's a 4.1mm plunger, that's TINY. Perhaps I'm missing something and it's a 10mm plunger, in which case that would be ok. But I'm thinking it is 4.1mm plunger with an RS2596 governor.

Dad had an OM352A in one of our old lobster delivery trucks... a 1116 if I remember correct. Anyway, it had some nice low gears, but it was off the governor at 53mph downhill and only about 45 uphill. I believe it was a 5.7L engine.

 

That's a 10mm pump. Better than a 9.5 which is what they put on alot of John Deeres.

There's 2 ways to setup the lube on an A pump. One is to plumb it into the engine oil system and let it run out the front of the pump back to the engine oil sump. The other way it is a self contained unit with its own lube oil, they hold about a pint and you would have to change it periodically. Use the same oil you use in the engine.

 

thanks, so is the 10mm about the same or larger than a Dodge P pump? and it must be self contained then because there isnt any open ports for oil, just fuel


heres some pics of some other OM352's at work

Dodge p-pump is 12mm, so yours is smaller.

 

ah ic. would dodge delivery valves fit then? i mean some laser cut ones?

 

What kind of pop pressures do the OM352's run? Isn't it an indirect injection engine?

 

Sounds like what you have is best used to weigh tarps down to keep them blowing off. Only 1 small step above rocks.
