I have a 4bt with the cpl#2302 I'm wanting a little help with pump id The numbers from the side are 908 bosch pes4a95d120rs2880 and from the back rsv475...1250aoc825r 392 8665 0010 any specs would be great this is a low hour engine from a gehl piece of equipment but not shore what. It also has the hx30w turbo but not intercooled. I have a hx35w from a 04 dodge and would like some thoughts on a twin set up using the hx30 and hx35. Thanks Nick:rasta:

About all I can tell from the numbers is that it is an A-pump. The Governor is a load sensing RSV, and should be suitable for a swap. I have a similar pump on mine. If I'm not mistaken, the high idle on the pump is 2500RPM, as it is set right now.

Not sure how the HX35 would be, paired with the HX30. I'm looking for an HX40 to go under mine.

The coding in my Isuzu manual for these pumps gives the following:

pe denotes inline pump

s denotes with flange

4 denotes 4 plungers

a denotes size in this case a Bosch A type pump

95 is 10 times plunger diameter in mm

d is design code (d is later design than c)

1 denotes type of lift pump, 1 is without pump, setting mark on left side of camshaft

2 denotes location of governor, 2 is governor on right side

0 denotes location of automatic timer, 0 is without automatic timer

r denotes direction of rotation viewed from drive end, r is clockwise

s2880 is a design code

The other number is for the governor:

rsv is rsv type

475 is idling pump speed (remember IP turns at halve engine speed0

1250 is maximum pump speed (adjustable)

a denotes IP pump is a Bosch A type pump

oc825 identify number of flyweights and springs (but may have different for the rsv, which I don't have info for)

r is mounting position, r for right hand

sorry can't help with the remaining numbers.

Which service book is that (it should have a # in it somewhere in the front)?

I have been looking (evidently in the wrong places) and I haven't found an 'A' series specific IP manual, and any mauals I have found are on Epay and go for more than I can afford right now.

The P3000 , P7100 and A pumps are high pressure .

Curious as to the output of the engine, and the type of turbo. I'm guessing an HX30.

Nexrussian, I have some information about the A-Pumps, purchased from Bosch. Unfortunately, it is in VHS video format, until I can get put on DVD. Also have the video for the rsv governors.

Doug, I am interested in that, if nothing else the part number would be handy (so I can pester my local rep :D , kidding). I would be interested though, thanks.

I got the A pump and a set of RLD governor (as fitted to my Isuzu 4BD1-T) videos from Bosch, IIRC some were free.

From the labels:

Bosch
A-Pump

STVV A

RLD Mechanical Governor
Zexel P/N RLD/*****-1 Volume 1 of 3

***** is some part of a number that has been blacked out - I don't know what to make of that.
