61K10 build

[61K10]

Finally got the tk back on the road. The new disc brakes are night and day from the power/drums set-up i had. It was worth the $$$ and time spent adding them to the closed knuckle axle. Now about the steering with the 4deg shims added to the ft axle. It has much more feel and not wanting to wander as it did before. Another plus! Need to drive it some more of course. also need to run it in 4h to get the ft ring & pinion broke in some. I actually used it as a tk, went to ACE and got some dirt/potting soil for my garden. It still makes a nice gear wine going down the road under power and deceleration, but free wheeling it's quiet. old sm420 and a 221 i guess!

A pic for you TJ---a working tk lol.

Hey hey! lol! Don't scratch the paint now!

Awesome Kimble! I'm glad your hard work paid off. And that your putting it to work like you should be!

[RANDY COX]

Looking good Kimble I like how you added back those reflectors below your tail-lites...
sumthin bout a truck...these truck were work horses back in the day...

[61K10]

Randy--when i was in high school i had a 58 chevy sfb pu and took it to school in the 10th grade (just got my lic). the hwy patrol inspected my tk for safety. they said i had to add reflectors as the tail lights did not reflect. I have seen a lot of them on old tk's of all makes.

[61K10]

Thanks Jason--I still need to make my headache rack, some more under coating and sound deadening and maybe air down the road. When i win the lotto i will buy a new bed lol! What have you been doing with your two?

Kimble,

Did adding the disk brakes increase you Dana 44 front axle WMS to WMS width?

My '64 WMS width is 65 1/2" and the '79 disk brake Dana 44 is 67 1/2". Just for information will measure the spare '69 K20 Dana to see its WMS width.

Trying to determine the front wheel/tire track that looks original/ good. Will likely put the core support and one fender on the frame to see how it looks currently.

Thanks,
Les

Les--will set my old stock spindles next to my new spindle set-up and measure. will post up a pic.

[61K10]

Les--looks like 9/16" wider than stock. (disregard caliper bracket just floating). the open knuckle hubs are shorter also. My rear axle is narrower than the front at 62". I bought the 1 1/2 wheel spacers for the rear, but they looked funny looking under the tk at the wheel. Don't know why they built the front and rear axles that way.

Kimble,

Thanks for the photos, they are helpful. Gives more information on front track, for different options when adding disk brakes.

Thanks,
Les

Kimble,

Looks like I need to change out the seals on my Rockwell T221. Just sitting their and spinning it makes it leak some. Did you change your out? Getting the seal from a person who has a lot of parts for the T221. Planning to double up on shaft seals per his suggestion. Also, will epoxy two magnets to the bottom cover to collect small metal wear parts. He reports these guys generate some metal as they wear. Also " we are much better of having the divorced 221 as they do not have the imput shaft issues the married ones have".

Did you get to find the van brake hose part numbers you are using.

Got rid of the Rockwell. It has a design flaw. Some bearings are submerged in gear lube. Others have little catch cups cast into the case which collect flying gear lube. If I remember correctly it's the rear bearing on the main output shaft has neither. Lost that bearing twice. First just above the Mexican border near Mexicali. Removed the TC, had a long driveshaft fabricated and finished our trip. Second time (running a factory lubricated bearing) was it. Out came the SM420 and the Rockwell and in went a (totally rebuilt)SM465 and NP205.

as i said earlier the brake lines are from i think a 75 p30 and are 23"+ long. (rockauto lists most specs) sense you are using a different axle, measure what length you need. I have very limited travel in my ft axle due to my pto drive-shaft.

Kimble,

Thanks, will check out Rockauto.

Kimble,

A question on your rear wheel location PLEASE!

Have a plan for my front wheels now. Going to move each wheel in one inch from where they are now.
Currently have 3" BS on 16x6", will change them to 4" BS, because I have the '79 axle.

Working on rear wheel position now. Current setup has most outer lip of wheel, 7" from outside of spring pack. Photo of how I measured mine. If you have time, can you measure yours please.

All your photos/information showing your trk wheels/tires is a big help, in getting the stock look. Mine came with 10" wheels.

thanks,
Les

[61K10]

Mine are about 6" but i have an HO-33 eaton rear axle. at 62" wms to wms.

[aotte1]

Kimble,

Thanks for the measurement on your trk. Mine measures around 63.5 WMS to WMS, ( 63.5 is what CaptainFeb says for "C" trucks with newer 12 bolts, later '70 and up). So it is .75" per side wider then yours. Originally thought it was a '65 axle because the gears were dated '65, however, fooled me as it is a newer axle.

Do you think the .75 wider axle each side, and 16x6 wheels, same as yours, will fit nicely in the rear wheel wells? You said earlier you tried some wheel spacer, however, did not like how they looked, from under the truck. My wheels are like yours with centered BS. If needed, to move wheel and tire in more, I can increase my BS from the centered 3" to 3 1/2 or 3 3/4 " easily.

Also, the 235x85x16s are about 0.3"s wider each side, then the 215s. So in total my wheels/tire will be about 1" wider in the wheel well.

Thanks,
Les

[61K10]

Les--should be just fine with that axle and wheels, and should look good also.

[aotte1]

Kimble,

Thanks, sounds good.

Been trying to rebuild my front calipers that came with my '79 Dana 44, just could not get the pucks out, after hours of trying. Feel they are to corroded to reuse if I could get them out. Going with rebuilt A/C Delco fully loaded ones for about $50 ea.

Once they are installed, will measure what length brake hoses needed, and then off to "Rock ...." To find them.

Thanks,
Les

[61K10]

Les-- here is a pic again of mine. They have a bend just after they bolt to the calipers. disregard the tubing on the other end. I have used compressed air to remove the pucks, just be careful lol.

Great details, you guys are going to save me so much time...eventually. Glad to follow both of your builds.

[61K10]

_mg what are you building?

I have a '64 K10 LWB like Les'. Not actually doing much with it at the moment, hoping to get some time this summer. In the meantime, learn, learn and more learn!

Kimble,

Got my new ACDelco fully loaded calipers for '79 Dana axle and they seem to not fit, maybe to tight. Need to do more research, and get my cores back, and see any difference. They looked generally the same, next will do some measurements, to find differences. First will check to see that they are correct for the DB5 brake option. It has the thicker rotors at 1.25" vs standard at 1". All '79 K10s should have the 1.25" front rotors. These calipers may be for the standard rotors, the box part number is correct for '79 to '80 K10. The caliper piston is also bigger diameter with the DB5 option too.

Checked out the caliper hoses on Rockauto, found P10 and 20 hoses in the range of 20 to 23" long. The stock '79s are 18" long. The end hose fitting to the hard brake line is a little bigger then the stock '64s. Not sure how to accommodate this yet. All the brake lines are undecided, as going to dual MC and disks up front, requires changes. May just make them.

Had a new front driveshaft built as my old one was bent. had a wobble to it. also a new lis-plate with the correct numbers. You 4x4 guy's need to post up on your builds.
