Engine/Transmission (1998.5 - 2002) vp-44 interchange

[GIT-R-DONE]

As far as I know, HO pumps (028 spec) only work on HO trucks and the SO (027 spec) pumps only work on SO trucks.

Mr. Fisher, could you comment on this? Is this true that these are not interchangeable form S. O to H. O. or visa versa? Thanks

I'm going to try to convert my -028 to -027 internals. We're only getting about 80 hp extra out of our Haisley E box which is extremely hot. The fuel system is steady on 10 psi. I'll keep you informed on what is required for the swap.



PS. If you could give me a part number for the hyd plunger you are talking about I would appreciate it greatly.



Thanks,



Brayden

Hope I don't get flamed here! :--) but I "THINK" I can recall several years back my dad owned a Ford Louisville tandem dump truck that had a "Triple Nickel" or "555" which WAS a cummins engine. It was a V style engine and it made the dump into a dragon fly truck. "Drag it up one side of the hill and FLY down the other"

I just thought I would confuse the topic a little more. I know two TDR members that have been running the "midrange" pump with great success for a while now. Maybe either one of them will chime in with some numbers.

"midrange" 029

Git,

Iv'e Had Customers Who Have Installed Ho On So Eng. And Vice Versa By Accident, And They Have Worked However There Has Been No Noticeable Difference For So Customers Who Got An Ho Pump, And In Most Cases The Customer Returned With Code Problems.
