Anyone on here parting an H-3? I am in need of two locks for the Idler adjusting screw.

These would be for the early design which carried the 1.250" B-7 threaded adjuster.

They could be machined but likely cost prohibitive.

Please send a PM with price and availability. Thank-you...Orangeman

I would hazard a guess, that a d-15, or d-15II radiator would fit. measure the distance between the 2 bottom mounting holes, and I'll see if it matches my d-15II.

hi, my bottom holes are the same as the top ones & they are 19 inches from side to side. the radiator is 21inches tall with the top water port is in the middle & the bottom one is on the left. thanks tom

Bottom holes I am referring to are the 2 tabs, that stick out, bottom, forward of the radiator, 1/2" holes, I think. I'll try to measure the old radiator out of my D-15-II, when I go get the tractor to cut hay today. Otherwise sounds like the same radiator.

My radiator off the D-15II is a tad taller, I think, than your H3, tab holes are about 13-1/2" OC apart. Double check the height measurement, from the cap gasket surface to the bottom of the radiator.

diydave my bottom tabs are 13-1/2" apart & the height from the top of the filler neck to bottom of the bottom tabs is 23-3/8", I also noticed on the top tank in yellow crayon like from a junk yard,is AC D14.also on my rad. the side tabs as I call them are 6-1/4"apat & they are 3-1/4" up form the bottom of the rad. these are threaded nuts which are 5/16x18thread &these are what attaches the rad. to the 1/4"plate that goes around the rad.from one side around the front to the other side & is about 25" tall & attaches to the frame of the dozer.

Sounds like you found what to look for radiator wise.
