BrothersGarage Posted January 21, 2020 Report Share Posted January 21, 2020 Sick as deal on those rims! What's nice is when you refinish them you can change them up with the color or bolts and make'm yours! 2 Quote Link to comment
wakemaniac Posted January 21, 2020 Author Report Share Posted January 21, 2020 Worked on the headlights wells/buckets that were very rough...decided to completely grind them off and retrofit the 521 ones. It works with the 520 fenders...just need a little trim in the lower corner to clear blinker in the 520 fender. 520 head light assembly bolts on the 521 wells. Got a few goodies by the mail : 2 Quote Link to comment

They riveted thin sheet metal over the rusted pans in 1979 (found news paper between the 2 layers). I drilled the rivets and took those as a model. Went to a local shop to have them cut and bent with 14 or 18 Gauge cant remember but its pretty stiff ! I dont have any measures...they just copied the old ones ! 1 Quote Link to comment
wakemaniac Posted July 28, 2020 Author Report Share Posted July 28, 2020 It's been a little while ! Here's the update : Finally got the cab done and painted. Just dropped it on the frame. Wheels got powdercoated as well. Will work on doors, hood ans fenders to get them painted before winter. Now that the cab is on the frame, I will be able to put back a lot of stuff together !!! Had half a gallon of single stage Sikkens poly-eurethane left from my old boat refurbish. I just love the color !!! 3 Quote Link to comment

wakemaniac Posted July 29, 2020 Author Report Share Posted July 29, 2020 Got two quick little questions : - what is the exact thread for the seatbelt in a 1968 (it would be STD right?) - what kind of oil to you use for your steering column gear box ? Thanks !!! 1 Quote Link to comment
DanielC Posted July 29, 2020 Report Share Posted July 29, 2020 On1970 521 trucks. the seat belt bolts are 7/16-20, same as lug nuts. Use 90 W gear oil in the steering gear box. 1 Quote Link to comment
datzenmike Posted July 30, 2020 Report Share Posted July 30, 2020 The 620 specifies GL-4 which makes it easy, just use manual transmission oil. The boxes are similar I just couldn't find if it was the same for the 521. Daniel, are there any brass or copper bushings or parts in a 521 box??? 1 Quote Link to comment
DanielC Posted July 30, 2020 Report Share Posted July 30, 2020 I do not know if there is any brass, or not in a steering gear box. 1 Quote Link to comment
thisismatt Posted July 30, 2020 Report Share Posted July 30, 2020 The worm ball box (whatever it's called) always seemed to look like brass or copperish colored...not sure about the bushings either. 1 Quote Link to comment
datzenmike Posted July 30, 2020 Report Share Posted July 30, 2020 Could be a hardened phosphor bronze alloy like the early intake valve seats. Anyway, to be safe use GL-4 transmission oil. I've taken later 720 boxes apart and there are needle bearings on the sector shaft, 521 and 620 were bushings.... maybe copper/brass? 1 Quote Link to comment

Cahoon520 Posted August 3, 2020 Report Share Posted August 3, 2020 I have a transmission mount if you still need one. It's brand new in the box, I ordered this one for my truck but it was not right. 1 Quote Link to comment
wakemaniac Posted August 18, 2020 Author Report Share Posted August 18, 2020 (edited) Re-assembled the steering column last night....what kind of loose do you guys have in your steering before wheels actually turn ? Ball joints/tie rods all new. Its really a loose in the steering column before the brass/cooper gear (like the picture above) starts moving ....steering must be close to 1/5 of a turn before something happens ! Is it normal ? Seems a lot and might be annoying on the road ! Edited August 18, 2020 by wakemaniac 1 Quote Link to comment

Seems a lot and might be annoying on the road ! There is a small adjustment screw on the steering box.... Give that turn, that should take out some of the slop.... I'm not sure how much it should wiggle, I adjusted mine to have just a little movement, because I didn't want to over tighten it... 2 Quote Link to comment
thisismatt Posted August 18, 2020 Report Share Posted August 18, 2020 Just have to check there's no bind at full lock. Most wear is near the middle. Check with both wheels off the ground. 3 Quote Link to comment
datzenmike Posted August 19, 2020 Report Share Posted August 19, 2020 Make sure wheel bearing have their pre-load set properly and the idler arm is not at fault. Worn king pins can add play to the steering also. There is about a 20 to one steering ratio in the 521/620 so even 1/16 inch of accumulated wear in the system will translate to 1.25" of steering wheel slop. 2 Quote Link to comment
wakemaniac Posted August 31, 2020 Author Report Share Posted August 31, 2020 Few more hours on the 520. Getting body panels ready and primed (and maybe painted) before winter hits ! Trying to get her done before june 2021 !! 3 Quote Link to comment

I reopened the gearbox cover and found the issue ! I skipped one tooth when I put the column in. For some reason couldn't get it in without taking off gear box from frame to get a better angle. Now its in and pitman arm moves right off when turning sterring ! Cheap fix lol Edited September 25, 2020 by wakemaniac 1 Quote Link to comment
