1975 1120 injector pump advice

[espacef1fan]

I have a 1975 1120 and the injector pump is leaking. The local diesel shop said it is a “CAV” type unit and would rebuild it for $400-up depending what was wrong. He said buying new was stupid expensive but I’ve found some new pumps that claim to fit for $600 or so but I’m unsure of their compatibility because my pump has no data plate visible(while installed anyways?)

I’ve attached a few pictures and I’m hoping someone here can tell me more about what kind of pump I have.

If you carefully remove paint on plate attached to your tractor's IP you should be able to read pump ID info. JD did sell aerosol paint remover that would remove the paint. JD part # is AR91772 which cross references to DPA3432F530;

TxJim is correct.. The circle is the name plate w/ all the info u need to search the pump..
I will send u an pm or email..
But why would u spend 600.00 vs 400. + ??

He said that price starts at 400 but made it clear that if he found no old/worn parts in my 40 yr old pump.......

So did some gentle wet sanding and it seems stamped




I’m unsure which is a model number or otherwise.

The bottom number seems to have a number finished with an etch tool suggesting it’s a serial number.


Here are the numbers best as I can read them left to right , top to bottom.

343290
58 800 5 2675
0928920????
