Yes it is an MW pump It is probably off of a 466 truck motor but not sure.


In your one number you can see where it says pes6mw1100******. the"MW" meens that it is an "mw" pump. A p pump would say pes6p***** and an A pump would say pes6A*********.

With out wasting a ton of money? ............... No....... you will still have a junk M&W pump. Save yourself the time and money and get a good A or P pump fitted to your class rules

Fits a Case IH Magnum 7140 tractor or similar model with the 8.3L Cummins engine. That pump will do aprox 220-230cc max in stock form. With Cut dv's it will do 240cc but that is it. Pump has the small bolt flange (same as A series Bosch). Oh and i will be the first to go on record and state that "M&W did NOT manufacture an injection pump"...Get it right, its a Bosch MW model injection pump.

How many people have to advise you it's junk, that means people have messed with it and it's just ditch filler.

Some people just assume that he is putting it on a super or pro stock I guess. Depending on the class he will be fine with the pump. Need more imfo before you guys go ripping him a new one.

i was planning to put it on a hot farm ( 466 cid with a 3 in 3 out turbo and open rpm) i just wanted to know if it s worth it to put on and run it and what i could do to it for a little more power, could it run against a rotary pump? and what kind of cc 's could it make?

Re: a pump or p pump January 08, 2012 12:30PM
wouldn't it be great though if you could use one as a performance pump in place of an "a" pump? i would take it off my old man's 5288 and put it on. if i recall correctly from my days of workin at a pump shop the "start retard" flat top plungers are the down fall. and from i've been told there is no "normal" plungers and barrels made. but the cam is better than an "a" stock for stock that is. if my information is correct maybe this will explain to the guy why it is not suitable for performance. certain people just shouldn't be allowed to talk about pumps if they don't know what they are talking about. don't just say oh it's junk. good luck in your endeavors JS!

I realize that since you have this in your hands and prob got it for free you REALLY want to use it. BUT the fact remains ................ IT IS NOT A PERFORMANCE PUMP and will not be up to the task you want it to no matter how hopeful you are . Several guys have given you the specifics of this pump and its LACK of capability. Dont waste your money ...................... All this advice has been free!!! Working on that pump WONT BE!!


And Dr Diesel told you the potential cc out put of it which is far below what you are gonna need.

Only thing good about the MW pump, is the adapter plate & pump gear (if it was off a 466 IH), it can be used to bolt up a P pump The rest is a paperweight or doorstop.

For what it's worth, anything more than absolutly stock class this isn't the pump to use, but for those who may pull stock class, works. I pulled my 5488 in stock class and beat some cheeters with modified A and P pumps long ago, like 18 years go. Also if it was so bad, why did they put them in trucks, tractors etc. By the way, my 5488 is for sale on BigIron.com, check it out. Darin

The MW (not m&w!) is a great little pump. In a STOCK application. very durable, and with an rsv governor, makes a nice farm tractor pump. They are far from JUNK! (unless it's an SRC REMAN!)It is not however a pump with any potential for any class of pulling where you need more than 300hp! I know, it looks like a P pump, but it isn't even remotely close to performing like one. They were designed to be a low cost inline built completely by robots. It was to replace the A 3000 series pumps.

Darrin.............. The point being made is simply this. IF you are wanting to use this pump for a PERFORMANCE pump it is a waste of good money. IF however you are gonna put it on thousands of trucks and use it for a cheap reliability stand point well it will work for that. Yes a few tractors came with this pump as well but for the same reason ............. cheap and reliable.

the m&w pumps are not completly worthless the last one i had i sold it on ebay for 300bucks and i seen another one on ebay that brought 400bucks so if you dont use they still worth a little bit
