756D fuel pump throttle shaft leak

Anonymous-0 · Mar 11, 2014

Have an IH 756 D with 310 German Diesel. Have fuel leaking from the throttle shaft. Have tried to get parts from dealership but they don"t get the right thing. I need an O-ring that has squared off shoulders and is a square cross section rather than a round cross section. I would think a round one might work but cant figure out the size I need. I just know the one the dealer got me was too small and leaks worse than the old o-ring with a square cross section. Any what the right part number is or how to figure it out? Case ih online parts catalogue is no help...it does not include the fuel pump detail.

Which Bosch model VA pump do you have, AR, BR or CR? I have worked on those pumps for years, and none have ever used square section O rings at the throttle or shutoff shafts, but the old ones may LOOK like that when taken apart. There are some square section O rings on some pumps at the advance and head area. Very few parts are available, but gasket kits are so far. DGK 124 or DGK 125, depending on the pump model. CR with the line fittings straight is the later one, AR and BR with angled fittings are the early models used.
