Installed the redone steering wheel tonight. Things would have gone better except for I had safely packed away the retaining nut and it took me about 1hr of searching to find it.

I’m also installing a NOS horn button kit.

Hi Jordan

We've all had that experience of having to find the part we put away, what I hate more is getting it all assembled then finding the part.

But to your horn wiring, I've had problems on all three my trucks with the rub ring pickup down on the column. Finding that the repro parts are not quite long so the little carbon brush doesn't make good contact.

Will be interested in seeing if you find the same problem, and how you work around it.

Cheers Phil

...... it gets greasy and oxidizes over the years.......

I have used brake cleaner with a cue tip.....and a lot of patience....... there is also a special solution used by old radio repair shops..... it is intended to remove contamination and oxidation of the older mechanical contact swithces...... camera shops use it to clean the battery contacts on digital cameras......

On you rub brass band..... a wooden pencil that has a hard rubber eraser chucked in a small 1/4 drill will do wonders but some one needs to turn the steering wheel while you polish the brass band........... probably could find an ink eraser at staples that you can punch a 1/4 piece than crazy glue to the end of a wooden dowel.....used in conjunction with the above cleaners it should work. I have done my truck but could probably use another cleaning as the horn does not always work when the steering is pointed straight ahead but works if I wiggle the wheel......

Not sure about the cab 13 but on my cab 11 I need to remove the inside fender........

....and some say the good old days!!!!!!!

Good Luck

First time in a few years the truck is off the axle stands and back on its own wheels. The steering was hooked up today and all is good with all the rebuilt bits.

....inspect very very closely your steering arm?????

Mine came apart at the welded ball connection....... 70 year old weld was NEVER done properly....only surface weld.....sure went for the snow bank very fast........ on rewelding the ball end to the arm I noticed numerous hair line cracks in the inside of the curved portion. I had washed the arm prior to welding in the kerosene wash tank and paper towel dried them before welding.
The cracks only appeared when the welding heat travelled up the arm..... it caused residual kerosene to darken the hair line cracks....... much similar to magnaflux testing. I kept the steering arm as a souvenir and installed a spare one that I heated slightly but found NO cracks.

It's a weird feeling spinning the steering wheel one way and having the truck go in the opposite direction...... at 5 miles per hour I just plowed into a snow bank.

Cheers

PS.... now is the time to clean up the contact brass ring on the steering shaft.

[Jordan Baker]

The brass ring on that shaft was all cleaned up. New wire down the tube. Testing was done with the ohm meter. The horn button was pressed and the wheel turned full rotation. All is good.

Yes when I cleaned it up I checked out the arm. It was fine.

And now for more good news........

THE ENGINE IS IN....

All went reasonably well. I had some initial issues with balancing the weight of the engine. It fell off the stand and thankfully the hoist took the weight. The biggest issue I had was clearance between the cab frame and transmission. The frame was catching the top of the big gear in the transmission. I ended up using my floor jack to lift the cab frame up on one side. I then put in a metal spacer between the front cab mounts. Then I repeated on the other side. This still wasn’t enough. So I used the floor javk and some wood cribbing and jacked up the rear part of the frame. This gave the transmission the extra 1/8” it needed and it slid into position. All in all it went well after I had some supper.
I’ve got a few things to sort out but I’m happy I hit this milestone.
