I’m in need of a primer pump rebuild kit for a serial # 39d852 model# D326 engine
Thank you Lowell Coppin

Lowell: Glad you made it to the Bulletin Board!
I don’t have the parts your looking for, but curious as to what engine this primer fits? Not familiar with that model engine number; myself I have never heard of it. (What does this engine belong to)
See ya around, Gee aka Juiceman.

DW15 is one I think. If I remember right it’s the NA version of the turbocharged and intercooled D337F used in the DW20.

Hi Lowell,
welcome to the BB.
My old D337 had just the actual priming pump the same as this one fitted to a D343 in a 630 Tractor.
This was the standard priming pump of the day--later on they went to a dinky little brass unit that took for ever to prime big engines.
I stand to be corrected.
Hope your unit is the same and that the piston washers are still available--pictures help immensely to help you quicker and more accurately.
Cheers,
Eddie B.

The 7H1950 changes to a 1832823 and is $164.64 from Cat or $31.79 on ebay, aftermarket places should have them also.
