I'm not sure if this is the correct place for this question but here goes anyway.

I'm looking for guides on the various bosch inline pumps or any useful links or information.

What pumps are best p pump m pump mw pump how do you tell which is which etc.

Any help would really really be appreciated.

Thanks.

What do you want to achieve? What engine?

I'm no expert but here goes
A pumps are older, they were used on most older diesels either by Bosch or CAV/Diesel Kiki. Perkins, Isuzu
M pumps fitted to ~1980 onwards NA OM617 and all OM601/2/3/4/5/6 apart from the VE(?) OM602s.
MW fitted to OM617s 1974-1980 and 1980-1985 (US vehicles), some on other engines (IH DT466 one notable example)
P pumps like the P7100 are for larger industrial, Cummins etc (6BT pump onto a OM606 has been done before)
There's loads of other pump types too of course.
Only ever seen M and MW with 5 cylinders however. Don't know what pumps the 5 cylinder Deutz use...


1978 300D, 373,000km... OM617.912 with a Holset HX30W, 7.5mm IP, 711.113 5 speed (project car, 7 years off the road and counting ;/)
1977 250 270,000km (parts car)
1977 300D (ex 280) 500,000km

1981 240D 498,000
1975 HJ45 ???,000

There is a lot of info out here about p and a pumps. Mw, a little more scarce, but a lot of info on this forum if you search. P-pumps are normally your best bang for your buck, and for power. But like Scott said, they are mostly for larger engines, and don't fit directly to the mercs, so retrofitting them could get pricey.

That's why most people stick with the factory merc pump, whether it be mw or M pump. I put a Bosch VE pump on my Perkins, and it was actually pretty cheap to do. The worst part is bending your own lines. I say that just to point out that any pump can be put on any engine, if you want to do a little engineering and work

Well I do have access to a lot of equipment at my work so that's no problem. I understand it that any pump will run any engine so long as the pump gear is matched to the camshaft gear as both rotate at half engine speed. I do have a few ve pumps and understand their operation and controls reasonably well. The problem with them is is getting near 400hp from them and a decent rev limit it seems.

So is a PES pump a p pump? What kind of pump is the om603 mechanical pump? And what is the RS number I've heard mentioned. Is there any clues in the bosch part numbers that tells about element size etc like there is with ve pumps

My spare OM617 M pump is
PES 5 M 55 C 320 RS 105

PES means something like inline, 5 cylinder, M pump, 5.5 elements....dunno the rest, RS is something to do with the governor? Hopefully someone like barrote can tune in, feels like the blind leading the blind here Tongue

I dropped Goran a line regarding pumps as I'm also interested. Here are the messages:

Hi there, I've a question regarding the mechanical pumps and their part numbers. I've found an Rs 156 and an Rs 157, but what's difference between them and for example an Rs 187 or an rs 203? Thanks!

Dieselmeken:RS156 is 603N/A 157 603TD RS203 is606N/A and 187 (?) not 181? is 603TD However manily differens is that over 177 you have a sharper camshaft, nothing that makes big difference and RS203 is the pumphousing 7-8 degrees angle in mounting flange, That is when you put a 603 pump on a 606TD you have to bend the injector lines a bit but with RS 203 it fits perfect from the beginning. All pumps are great to build superpumps of.

Hope this helps in some way!
