Some Assembly Required

• CATEGORIES: Features • TAGS: This site contains affiliate links for which I may be compensated.

Over the last couple of days I’ve been sorting through Rusty’s parts and putting it back together so its easier to ship (It sold this week). It almost looks like a real jeep again. I started with the bare frame that Ann and I cleaned up prior to the Alaska trip in 2017.

I thought it would be easiest if I reinstalled the engine and tranny and gas tank for transport.IMG_9633

With the powertrain installed, the body and front clip went together pretty easily. The parts have been sorted and boxed. It’s just about ready to go. IMG_9635

A Little Confused …

• CATEGORIES: Builds, Features • TAGS: , This site contains affiliate links for which I may be compensated.

A couple things confused me today. In this first example, we have at top the original gasket between the intake manifold and carb. On the bottom is the replacement gasket included in a rebuild kit. As you can see, it won’t work. Is the DJ-3A intake that unique? I know it uses a Carter YF 2392, so that’s unique.

Next up, the ends for the dragline. On the left is the new end and on the right the old one. The new one is taller and has shallower slots for installing it. The old end is shorter and has much deeper slots (those deeper slots are really helpful) . Anyone know why these are so different? Between the longer end and longer springs, I couldn’t put all the parts together around the bell crank arm (and I tried). In the end I was forced to use some old and some new parts.2017-06-24-draglink-end-piece-comparison

Note the difference in the spring heights. Try as I might, I could not compress the spring enough to install an end. I changed to the old end.2017-06-24-draglink-spring-comparison

Once I used some of the old parts, I was able to get the draglink installed.2017-06-24-draglink

I also installed the dual master cylinder. The rear brake line connected perfectly. I just had to add one bend. The front brake lines were a big problem. You’d think trying to locate an 3/16-1/4 adapter would be easy, but it turned into multiple trips to the auto store, where I hunted for the right sizes with the right threads. The staffs at two different auto stores were not useful (nice, but not helpful). So, this will work for now, but I’d like to get the proper adapter and remove the connectors and line on the right side. 2017-06-24-master-cylinder-brake

Sunday morning we’ll 1) bleed the brakes and then, if all goes well with that, 2) replace the front springs and then 3) drop in the engine.

Creating Patterson’s Transmission Crossmember

• CATEGORIES: Features • TAGS: , This site contains affiliate links for which I may be compensated.

Someone on Facebook the other day claimed that DJ-3As were made from surplus parts. As with any model during those years, there were some DJ parts used on other models. But, as with other models, there are parts unique to the DJ-3A and I’m learning more about them daily, one part at a time.

Today I spent time working on the transmission crossmember. Because finding a DJ-3A crossmember was near impossible (and since Rusty did not have a normal crossmember), I got a CJ-3A crossmember from Chris McKay for Rusty. But, I’ve decided to use the stock DJ-3A crossmember off of Patterson on Rusty and keep that jeep as stock as possible, and DJ-3A-matize the 3A crossmember for Patterson. Here are a couple pics:

dj3a-transmission-crossmember3 dj3a-transmission-crossmember1 dj3a-transmission-crossmember2

So, to make the CJ crossmember a DJ unit, I will have to remove the transfercase cup and drill several holes.

Unfortunately, as I disassembled Patterson’s crossmember I ran into a couple problems with the rubberized mount for the transmission. Here’s a look at what I pulled off of Patterson. Note how narrow the two holes are for mounting the rubber piece to the transmission (too narrow for a standard T-90 mount:

DJ-3A Gas Pedal Linkage

• CATEGORIES: Builds, Features • TAGS: , This site contains affiliate links for which I may be compensated.

UPDATE: More DJ-3A carb info here:

On Thursday evening I spent time moving parts from Patterson’s stock, but tired,  DJ-3A engine to Rusty’s rebuilt M-38 engine so I could install it in Patterson. One item that caught my attention was Patterson’s DJ gas pedal linkage versus Rusty’s. Patterson’s appeared stock, while Rusty’s had a modified pivot point, probably the result of using the M-38 block. I decided to keep Patterson’s as it was and recreate the part for Rusty’s engine.

DJ-3A gas pedal Linkage: The linkage goes through the firewall to a pivot point on the driver’s side. When the gas pedal is depressed, a rod pushes an angle piece around a pivot, forcing a second rod upwards to a YF 2392S carb, causing the gas flow to increase.

yf-2392s-carb yf-2392s-carb2

Patterson’s real pivot piece (and it seems I misspelled carburetor in my pic).

gas-pedal-linkage

This shows the piece after removing the parts. The pivot bolt is solid on the end with a hole for a cotter pin.

gas-pedal-linkage5

Example of what I removed from Rusty (bottom) and the bolt I will use to make a new one (top with new threads extended up it so I can add a bolt). The biggest problem with the custom piece at bottom is that it had no cotter pin. It was only held on by a bolt, which could have easily have come unscrewed as the gas pedal pivot piece moved back and forth.

Rusty’s T-96 Transmission Rebuild

• CATEGORIES: Builds, Features • TAGS: This site contains affiliate links for which I may be compensated.

Another thing I got accomplished recently was the rebuilding of Rusty’s T-96 transmission. It’s been a couple decades since I’ve rebuild a T-90, but I think a person could follow a T-90 side shift guide when rebuilding the T-96 (I didn’t think of this until after I was done — instead I used an old rebuild manual from the late 60’s that has rebuilds of 35 different styles of transmissions). Once again, I thought I had more pics, but I didn’t. So, this isn’t a step-by-step overview.

I took this photo at the beginning of the tear-down to remember which way the speedometer gear should face. The lack of a transfercase is part of what makes this rebuild different from most other jeep transmissions. 
2017-05-20-transmission1

Here’s the transmission with the input shaft pulled forward. My first gear and second gears were a bit worn. 2017-05-20-transmission2

Once I removed all the gears, I discovered the reverse gear had a broken tooth. 2017-05-20-transmission3

Close up of broken tooth. Thankfully, Charles Tate had sent me a box of T-96 parts that included a reverse gear. I was also able to replace the entire bottom cluster, first gear, and second gear. That saved me some money!

2017-05-20-transmission6

To remove the side shifters, a pin has to be tapped out. I was able to remove the 2/3 gear shifter, but not the first/reverse unit. Since there was no critical reason I could see for removing the first/reverse mechanism, I left it as is and cleaned up the housing.2017-05-20-transmission4

Normally, I’d paint the housing before assembly. However, with time being an issue and lacking enough warmth on the rebuild day to properly paint it, I will paint it at a later date. 2017-05-20-transmission5

One other unique thing about the T-96: it requires the use of a special speedometer cable that is also used for Jeepsters and wagons.

Assembling a DJ-3A Column Shift

• CATEGORIES: Builds, Features • TAGS: , This site contains affiliate links for which I may be compensated.

Yesterday I assembled Rusty’s column shifter. In my head, I took all kinds of photos. One in particular I took (again in my mind) showed the layout of all the parts prior to assembly. Alas, somehow that photo never made it onto my phone!

The DJ-3A shifter is slightly different from a VEC CJ-2A shifter. I can’t say how much it differs from a Jeepster or wagon column shifter. But, i can say that following these VEC CJ-2A instructions were very helpful.

After laying out the parts (and not taking a photo) I began the assembly process by learning how to install the horn wiring. After looking up how to do it on a 3B (thanks CJ-3B Page!), it turned out to be quite easy.

Step 1) Thread some of my grandfather’s wire through steering shaft.

2017-05-20-column-shift-assembly1

Step 2) Attach the wire to the horn wire end. In this case, I ran it through wire connector and then bent it so that the wire would not pull back out of the connector. 2017-05-20-column-shift-assembly2

Step 3) Pull the wiring carefully through the end of the shaft.  2017-05-20-column-shift-assembly3

With the wire installed, next on the list was assembling the shifter. The first step involved installing a washer, a spring, and a second washer onto the column shift tube Next, the interior shift lever must be screwed onto the shift housing. Then, slide the shift housing onto the column shift tube, pushing it far enough up so that a special metal pin can be inserted. Once that is done, you have to weld the end of the tube to the pin to secure it.2017-05-20-column-shift-assembly4

Getting Tanked

• CATEGORIES: Builds, Features • TAGS: This site contains affiliate links for which I may be compensated.

During my brief visit to Seattle the weather was most uncooperative. Today it was rain and hail, intermixed with sun. Two days earlier it was thunder, lightening, and downpours. So, I wasn’t as productive as I would have liked. Still, I managed to clean some more parts, order some parts, and work on the gas tank.

Not surprisingly, there seems to be no aftermarket replacement tank for the DJ-3A. I’m pretty sure a DJ-5 or rear CJ-5 tank would fit just fine, but I didn’t have one readily available and, besides, I was trying to stay with the DJ-3A tank. After some searching, I found one with all the parts, but it was a bit dented.

tank2

This tank took a pretty good hit.

Today I decided to get the dents out. With nothing to lose, I started by drilling an access hole in the good side so I could pound out the worst side.

2017-04-06-gas-tank5

My tool of choice was a 20 pound pry bar that had a round surface at the top. So, I inserted the bar upside down into the newly drilled hold and began working out the dents. It worked surprisingly well.

2017-04-06-gas-tank6

I also had a small sledge and a smaller bar with a rounded end that helped remove some dents. Continue reading

More Parts Painted ….

• CATEGORIES: Features • TAGS: This site contains affiliate links for which I may be compensated.

More parts have been painted.  On my next visit to Seattle (in a couple days?) I will be pulling the brakes to see what I need, checking the rear end, and working on the gas tank and readying that for installation.

2017-04-28-parts-rusty-paint2

Today I’ll be cleaning the and painting the bell housing and cleaning the generator and starter.

Rainy Days Go Away!

Ann is not afraid to get dirty!

Unlike our sunny Friday, today was a rainy day, so any thought of blasting the frame was put on hold. But, we did get nearly all the parts removed from the frame and the engine/transmission ready to pull out. The more we removed, the more we could see that poor Rusty had come from an abusive home.

Case in point: the transmission cross member. Both sides of the frame where the transmission crossmember normally attaches have been beaten, suggesting that the jeep was often bottomed or high centered. That would also explain the need to install a custom cross member:

2017-04-22-frame-crossmember

You can see the wave along the bottom rail. I play on straightening it and then added an extra piece of metal to about a foot long to add additional strength along the bottom of the frame.

This net photo shows the rear passenger spring. The front portion of the bottom leaf is bent down quite a ways. This is slightly problematic in that there aren’t off the shelf springs for DJ-3A convertibles (that I know of anyway).

2017-04-22-springs-bent

I don’t know which year this image was printed, but it highlights the different springs among models.

dj3a-spring-options

Note that the hardtop version had different numbers of springs on the left vs. right sides. From the CJ-2A Page.

To make it more confusing, I have five leafs in the front and four in the back (on both sides). I think I should have only 3 leafs. Perhaps the previous owner broke them and installed heavier ones? Or, the number of leafs was changed after 1956? I don’t know.
