Injector pump rebuild

Any ideas on the best place to get HMMWV 6.2 diesel. Stanadyne db2 829-4879 pump rebuilt?

Stanadyne website?

In my neck of the woods I use diamond diesel, they are a standadyne dealer....they do excellent work.
have used them for years.

Hi all,

I have the same numbers on my Stanadyne: DB2 829-4879
But how are the Stanadyne injection pumps identified?
By the first 2 characters + 4 numbers: DB2 829 only or is the complete series: DB2 829-4879 necessary in order to determine the correct injection pump?

Thanks,

Jake

Not sure of your question, if your have a 4879, then you need a 4879.
db2 is a mechanical pump.

The first two digits represent build date month and year. In this case, J is September, 2 is 1992, and 5 on the 4126 indicates it was built in 1995, as validated by the '95' casting mark.DB is for rotary distributor-type head, where each cylinder gets it's own injection port and pipe, supplied by single barrel.2 indicates two opposed pumping plungers, driven by steel rollers in ceramic pillow blocks8 indicates number of cylinders31 indicates 0.31" pump plunger diameter, used in the 6.5 pumps. 29 is 0.29" used in 6.2 pumps. 4911 indicates specifications to which pump was built, J is assembly plantAlso on label is inj pump serial niumber, and customer part number - GMC, Chev, Ford, etc
