j hancock Posted April 27, 2020 Share Posted April 27, 2020 In lieu of pictures or some numbers to identify the box, how bad is it leaking? Pouring out or just weeping? Work or hobby truck? If it is a hobby truck or just weeping, drain what is left of the fluid and then fill the steering box with John Deere corn head grease. Corn head grease is soft enough (NLGI 0) to use in a steering box but is typically thick enough not to leak out. https://www.greenpartstore.com/John-Deere-Special-Purpose-Corn-Head-Gun-Grease-AN102562.html 1 Quote JimIt doesn't cost anything to pay attention.

Brian L Blaylock Posted April 27, 2020 Share Posted April 27, 2020 That 20QCA512 is more than likely the Mack part number Quote Link to comment https://www.bigmacktrucks.com/topic/62252-69-u-model/#findComment-449840 Share on other sites More sharing options...
steelman Posted April 28, 2020 Share Posted April 28, 2020 Do you have access to a good bearing,seal supply House? Given shaft sizes, depth of seal and type of seal (which should be apparent to a good supplier), and you should be back in business in a day or two.

mechohaulic Posted May 6, 2020 Share Posted May 6, 2020 where in ct are you. stone construction (exit 14 off 84) last I saw had a manual steering box sitting on the shelf in a very messed up parts room. George still has the #1 R607T ; doubt he will use the box. I've worked for stone for 25 + yr : 20 yrs ago. was there last yr helping out. heard there is a superliner hood in one of the storage trailers and a good bumper also. interested tell ryan ::: Dave sent you.

My DM steering box is held on by about 35 bolts, (exaggerating) and my U model has like 6. My U model has a single 1/4" frame rail, my DM is two 3/8" rails.
