Since I had some extra help we moved on to putting the two toe boards in. This is another two person job. Once those were in we installed the draft seals for the clutch and brake pedals. The draft seal kit can be purchased from Kevin Lockwood.

I was going to install the steering column but needed to clean up the draft seal clamp for the column shaft first. I was also going to install the dimmer (tilt) switch but didn't have any number 12 screws. That will be the next project.

Making more progress over the last weekend. I got the steering column back in but had a problem. When the column is mounted in place there is a clamp that goes over the pitman shaft housing from the steering box. My halftrack has two brass shims that go around this housing before being clamped in place.

Image

Well, I put everything back as original and was unable to turn the steering shaft freely. I loosened up the column and things moved fine. I decided to take out one shim and everything seems to work fine.

Image

The drag link was installed next then all grease points up front were lubed. With excess grease wiped off I painted all the zerk fittings red and once dried installed the covers on the drag link ends. These are from Kevin Lockwood.

Image

One of the next items to reinstall is the drive line. Before I did that though I decided to put new U-joints in.

Image

The front axle was finished up by installing the flexible brake lines. At this point it is time to sand blast and paint more parts.

Image

I was able to get some small parts done in my small blasting cabinet but I heard from Don that the place we take our big stuff to get sand blasted burnt down to the ground last week. :'( I will have to see if they will still be in business or temporarily find another place.

More armor being painted.

Image

That's all for now.

Time for another update. Lots have happened since my last post. The big news is that I found a house and moving to the country, Yeah!! :mrgreen: With my closing date looming I need to kick it up a notch and get to work on getting the halftrack rolling again. I've been off work since last Friday through next Monday doing nothing but working on the halftrack. I've been at the shop everyday working at least 10 hours each day to get the halftrack rolling again. At this point it is not about getting it done but to get it at a point where it will move safely under its own power for the up coming move. Here is some of what I've done.

The all three drive lines are in place and the main fuel line is hooked up again.

Image

Painting parts is going on every day with the doors all done and finishing up the hood today. I still have to clean all the hinges and door components though.

Image

Image

My paint prep and bead blasting area.

Image

My parts remaining and staging area. I'm running out of parts to put on. :o I guess that's a good thing. :mrgreen:

Image

Finally, the halftrack as she sits today. The winch is installed, top center hood piece in place. Almost ready to roll....

Made a lot of progress since my last post. I got my other gas tank back from Don since he has his own tanks now. Both tanks are wired in and the fuel gauge works! That's a big plus. One modification I did was to notch the gas tank covers so I don't have to remove the fuel line each time. I've seen this on several halftracks as a field modification.

Image

I finished pluming the fuel line to the engine so it can run from the tanks but had problems starting the engine. It just didn't want to start but would run if dribbled fuel down the carb. After some trouble shooting It was found that the float wasn't allowing fuel in the bowl. Once adjusted the engine fired right up.

Don came over this morning to help with a few things like bleeding the hydrovac and brakes. I ended up having to disconnect my rear brakes due to rear hub seal leaks on both sides. So I'm using the front brakes for now. Once that was done we put the floor plates in and the front tires on. Lastly the steering wheel was installed.

You know what that means....

TIME FOR A TEST DRIVE!!!!!!!!!

This is the first time running under it's own power in two years. I don't know who was more excited me or Don. :mrgreen:

Once the ride was over we went out and celebrated with lunch then came back and worked on doors. The lowers are on but will need to do some massaging on the driver's side door. That's all for now.

OK guys, here is a long overdue update on my halftrack. Sorry, no photos with this update.

Between getting inspections done on my new house, signing papers and getting ready to move, the halftrack took to the side lines for a while. I have since installed the fenders, front bumper, doors, windshield armor, hood and headlights.

On the passenger side door I added the pocket for the lube chart. Some years ago I purchased one from Outsider, painted it and then put it in that safe place. Well, when I needed it I couldn't find it so I bought another one from Outsider and installed it. Yesterday I was showing Don something and I found it! :D

For the most part the halftrack is done. I still have a few items to address but for now it can be moved or so I thought.

Since the first test run I have been having problems with fuel starvation. I've tried changing carburetors, bypassing both fuel filters and fuel pump with no luck. From the fuel tank selection valve forwards all have been bypassed. this means the problem is somewhere from the valve back. Just when I was ready to give up Don, once again, suggested that I blow the line with air. I finally agreed and so far that did the trick. Big thanks to Don!! :D

This Saturday Don and I are invited to a car show so I have a few more thing to do to get ready for Saturday. I'm going to make another test run today and finish up a few more items then its of to the car show. I will try and get some more photos posted soon.
