still messing with 4020 tail light

55 50 Ron · Jul 22, 2020

Just info for anyone working on 4020 tail lights (maybe 3020 also). The original electrical terminals that go through the light body have screws on both sides and were rusted and busted. Went to buy new ones from JD. The parts catalog drawing isn't real clear and it crosses to a different number for replacement. The actual part I got is a rubber grommet which would be workable IF it was the right size but it isn't even close. JD's new part number is R1134R but don't buy as it WON'T fit. I measured the hole at.43 inch dia and panel thickness at .20 inch. The panel thickness is large because there is a lip pressed inward. I'll order correct grommets from Digi-Key

Hope this helps someone to avoid frustration.

I think Steiner and most of the aftermarket has the right plastic piece and steel clip that holds it into the housing

I run a wire through the opening and use black silicon to make the seal.

Tim,

That is a good idea. Thanks

SV,

I have some of the Steiner parts you mentioned but they are too large in diameter to fit. They are for the older John Deeres, 50 through 730 and all the letter's group.
