    3020 Engine Timing

    • Tractor chassis S/N says it’s a 1996 3020
    • Engine Serial number is 13E41046
    • Stamping on engine is R26160R
    • Injector pump is DBGVC429—4AF
    • Fuel Pump Part number is AR26509R
    • Parts manual says that the Fuel Injector Pump is for a 3010 engine. ???
    o Do I have the wrong injector pump?
    o If so, then should my timing be 10degrees BTDC or TDC???
     3010 timing is 10 degrees BTDC
     3020 is TDC

    According to JD parts AR26509 shows to also fit 3020. 3010 inj pump should be (STANADYNE NO. I-DBGVC429-BAJ) You must have had a fat fingered typo as no 3020's were built in '96 so you must mean '66

    It is a 66.

    According to the parts book both the 3010 and 3020 take the same pump. Mine is just a little different Roosa Master ending in -4AF. Do you have any idea what the BAJ and 4AF stand for?Click image for larger version.

    I have no idea what BAJ and 4AF indicate but there are inj pump repair technicians that frequent other discussion forums that I can ask.

    Here's one reply I recieved.

    DB means B execution of two plunger D pump with .920 rotor, G-mechanical flyweight governor, V= vertical mount, F= flange mount, C= clockwise, CC= counter clockwise rotation, 4 means four cylinders, 29 means .290 plunger diameter, next number is a spec number, letters are accessory code. AF is on fixed phase, no advance pumps, AE is on pumps like IH 460,560, and 660 with light load advance, AJ is on pumps equipped with speed advance. AL is seen on speed advance pumps with electric stop solenoid. Timing always needs to be checked per the service manual, or spec sheet may have it too but not always. JD 3010 and 4010 used AF, no advance pumps from factory, but a field update to AJ speed advance for better starting came out later. A different flywheel timing used for the AJ pumps. DC and JDC pumps have four plungers, DM pumps can have two or four depending on fuel delivery needed.

    Thanks. That explains a lot. I noticed that 3010 requires 10 BTC, and 3020 is TDC. At TDC it starts a lot easier. I wonder what the difference is in the engines from 3010 to 3020.
