On Hold

Update Monday July 28: the second clutch I ordered is on its way, as per FedEx, and should be here by COB tomorrow evening. The first one is still stuck at the warehouse.

I’m currently waiting on two clutch kits from two different vendors which both happen to be shipping from the same warehouse in Kearny, NJ, where everyone seems to be smoking weed out back.

To recap: the transmission shop called me last Monday while I was in a car driving through Pennsylvania, and I used my phone to jump on RockAuto to find the proper 12″ clutch kit and order it. They promised me I’d have it by that Wednesday, which came and went. The FedEx tracking system said the label had been created but they hadn’t received the package yet—which is how it stands a week later. I got impatient on Saturday and figured I’d nudge the universe by going to a second vendor and ordering the same clutch kit to see who could deliver it first. But the joke was on me: both vendors use the same warehouse (both FedEx tracking updates point to the same location, and when I look at the inventory on RockAuto, it says there’s only one left, down from three last Monday.

It’s been too damn hot to do much of anything outside—we got back on Wednesday and I spent pretty much all weekend hiding out inside, apart from taking the Scout to the local Lowe’s for a sheet of plywood and sanding down a fresh skim of filler on each of the doors to cover the PO’s ham-fisted install of cheap mirrors.

Clutch Update

The transmission shop dropped the clutch this morning and found some very interesting things. At some point in the recent past, a new clutch was put in with new freeze plugs, pilot bearing, and (possibly) a flywheel. But the crank bolts weren’t sealed and apparently backed themselves out, smoking the clutch surface and possibly the flywheel. Jack sent me photos of the inside of the case and all of the parts, and it’s just puzzling. He gave me a disc diameter and a spline count, and I jumped on RockAuto to find the right replacement. Within five minutes I’d ordered it over the phone, to be delivered Wednesday.

I’m so glad I didn’t continue trying to mess with it in the driveway; I never would have sorted this out myself.

Win Some, Lose Some

Saturday morning I farted around a little with Darth; I verified that the clutch slave is working when I press the pedal and that it’s got a full range of motion. So I didn’t bother bleeding it again. I also put a short hose and filter on the end of the gas tank breather line to keep moisture out of the tank, something I should have done months ago. Finally, I ran it up to temperature again and recorded a data log for future tinkering.

With things at a standstill there, I turned to the Scout to-do list. The number one issue there was fixing the re-awakened exhaust leak on the passenger side, which has been plaguing me for several years now. I put the truck up on jacks, pulled the tire off, and poked my head into the wheel well.

At first I was having an issue finding the leak itself until I found a suggestion online which involved taping the hose on a shop-vac with the blower reversed to the tailpipe. This quickly showed the donut around the heat riser valve was bad, which is what I suspected. I pulled the assembly apart and went through my box of spares to find the old riser assembly without the flapper (this valve is designed to stay closed to heat up the engine quicker, then open and allow exhaust gases to pass through to the muffler normally) and several spare insulating donuts.

The offending valve/joint is in the center of the photo.

After using pliers to straighten out the mounting flange, I put the old valve on, then tried a combination of different donuts to see which one would close up the leak the best. This was mostly successful, but the leak came back after a test drive. The issue is that the mounting flange on the downpipe has been bent enough times that it’s not providing a strong enough seal to the donut, and no amount of bending it back will fix the issue. So I have to think on that one.

I also bought a set of rotors for the front brakes. The ones on the truck have been warped for several years and are rubbing during normal driving, which heats up the hubs and bearings. I was all ready to swap them on Saturday afternoon when I realized this process involves removing the hub assembly completely—something I’m not prepared to do. So I’ve got to find someone who can do a brake job on the Scout for me.

A beautiful morning for a drive over the bridge.

Then I loaded it up with tools and drove 70 miles over the bridge to Easton to do some work at Karean’s house. The truck ran flawlessly; other than the rotors heating up the front hubs, she ran cool and calm even through 45 minutes of stop and go bridge traffic. I was completely heat-soaked; even though the sun was down, the residual heat and humidity plus the mobile oven underneath me made that traffic a miserable experience. Luckily I was able to do 40mph over the bridge and that cooled things down quickly.

Sunday Evening Update

I was really hoping I would be able to break the clutch free on my own, but it just didn’t happen.

With the new battery in place, the truck fired right up and when it settled in the Sniper brought the idle down to a reasonable rumble. I let it warm up for seventeen minutes and then shut it down. After setting up some cameras I followed the steps for breaking the clutch free: Put it in low gear, step on the brake, and bump the starter. I did this repeatedly with no success.

Then I figured I’d add more torque to the formula, and hooked a tow strap up between the Scout and the Travelall. Putting the Scout in low gear, I gave it about ten good tugs, enough to pull Darth forward about ten feet, but the rear wheels were still locked tight. I really don’t want to break anything, so at this point I accepted the fact that it needs to go to the transmission shop.

So I moved on to some other projects. Breaking out the sanding gear, I smoothed out the skim coat on the rear valance, prepped it, and shot it with IH rattle-can red. It now looks worlds better than it did when I got the truck.

Then I ran out to the Home Depot and pulled the trigger on a sheet of 3/4″ oak plywood for the rear bed. I’ve been looking and considering multiple different types of lumber for the rear floor: marine-grade plywood, pressure-treated plywood, and composite board used in boats. The first is difficult to find in this area; the second tends to warp over time and is hard to paint, and the third is exorbitantly expensive.

So, I figured I’d go with dependable hardwood. With a couple coats of heavy duty primer, and a good thick shot of undercoat, I think it’ll stand up to the elements pretty well. I need to figure out what I’m going to do with the inside bed. There are two options: I could cover it with rubber matting, the way the factory did it in 1963—I have a link to rubber flooring available on Amazon that someone else used in their truck. The trick there would be knowing what to use for adhesive. The second option is to polyurethane the wood, and add strips down to protect it. This option would make it a little more difficult to sleep on the floor, but might be cheaper in the long run. I cut the plywood to fit and laid it into the truck and was very happy with the results. I’ve been staring at that crappy uneven floor for two years now, and it really cleans up the interior of the truck.

I installed the cardboard glove box insert I got at Nationals. This took a lot more effort than I assumed it would: I had to remove the defrost vent and hose and figure out how to insert it through the glove box opening to get it in place. It actually doesn’t fit as well as I was hoping it would, but it’s better than having an empty hole in the dashboard.

Sunday evening I dug four sets of window cranks/handles/escutcheons from the green truck out of my bins and cleaned them all up. A trip to ACE hardware yielded three springs for behind the escutcheons, and I set up three of the four doors with proper handles.

So I’m at sort of a crossroads. It’s probably going to take a while to get the truck into the bay at the transmission shop. In the meantime, I can continue fooling with the Sniper, but I’ve got a lot of research and learning to do before I can make any major improvements there. And, it really helps when you can drive the truck around to help program the computer. There are a bunch of small jobs that can be done, but I can’t dig into anything huge.

Saturday Morning Plans

So remember back in May when I said I thought the alternator was bad? Turns out that was fine, but my battery was sick. I’d swapped out the starter last weekend but found that the battery itself was boiling itself when hooked up to the truck.

I pulled it out and let it cool down overnight. The next evening I got underneath and re-connected the wiring to the starter to make sure it wasn’t shorting out on itself. This made the engine much happier, after I dropped the battery from the Scout in,  it fired right up. I connected the old battery to the tender and let that top off while I was doing some other stuff, and when it measured 13V I put it back in to give it a shot. I got one crank out of it and then it died quickly, which told me it was irreparably sick.

Going on a tip from a Youtube channel I follow, I learned that Costco sells Interstate batteries for $100 less than the auto retail stores. I grabbed one Thursday night and dropped it in the truck. It fired right up with no complaint, and after shutting it down, an hour later the battery and its cables were comfortingly cool to the touch.

I don’t know what happened with the previous battery, but the signs were there months ago when I wasn’t getting much of a crank out of it. I guess there was a parasitic drain on it somewhere, and when I put the starter in one of the wires was shorting out, which cooked the battery to the point where it became a boat anchor. I’m going to watch this  new one carefully to make sure it doesn’t get sick like the last one did, because batteries are expensive.

In the meantime, I can tackle a couple of things this weekend: first and foremost is attempting to break the transmission free. This is going to involve running the engine up to temperature, which is fine in any case; another good data log will help me get back to the real job of testing and tuning the EFI system. I dove into the training videos the other night, and realized I have a lot to learn to get this thing running optimally.

Then I’m going to sand and paint the valance panel over the barn doors to finish that project up; even in primer it looks so much better than it did all chewed up.

Crossed Wires

The good news is that I installed a brand new starter on the Travelall this weekend. The bad news is that the battery might be screwed. Let me explain:

I’ve known the starter that came with the truck was going to need to be replaced since I bought the truck. It’s made a funny noise at the end of the start cycle the entire time I’ve had it, and lately it’s been showing its damage by heating up the battery cables after just a few uses. So I bought a new one on RockAuto and made plans to swap it out. I put the canopy over the front of the truck,  jacked it up onto stands, and started the difficult task of removing the old one. It’s in an impossible location: between the frame rail and the engine, and directly over both the front axle and Y-pipe from the manifold.

Once I’d gotten that out, I bench-tested the new one to verify it was working correctly, then hefted it up into place to bolt it up to the truck. When that was done and I was reasonably sure I had all the connections correct, I moved forward, pulled the mechanical fuel pump off the truck, and replaced it with a steel block-off plate I made last weekend. There’s no reason to have a useless pump  leaking oil everywhere.

I had to mess with the electrical connections a couple of times to get the truck to wake up, and I got it to start quickly and easily twice before trying to bump the transmission free, with no success. But then the truck refused to start—the electrical system refused to do anything at all, actually. I went out and found that the battery was hot to the touch, so I pulled it out and set it on the ground. It remained hot for hours afterwards, which leads me to believe I crossed wires on the starter somehow.

Update: verified. I pulled the battery out of the Scout, dropped it in place, hooked up the ground, and touched the hot lead to the battery: the starter immediately tried to engage, which means something is screwed up with the wiring. I did verify that the two extra wires are going to the right poles on the solenoid: the 12-12 wire goes to the R terminal, and the 14-12 wire goes to the S terminal. So I’ll have to get back under the truck, take the wires off, verify they’re all clean and not shorting on each other, and re-install.

Bench-testing the old starter confirmed my suspicions: it still works, but there’s a terrible noise at the end of the cycle when the gear retracts back into place—it sounds like the unit is grinding as it spins down.

In better news, I sprayed the two hubcaps I got at Nats with oven cleaner to remove the red paint; as it turns out there was a layer of red over black over white, but it all came off easily, and with a detailed scrub with some OOO steel wool I got both of them sparkling again. They look so good I’m kicking myself for not having bought four.

Finally, I took advantage of a coupon code and bought an EFI tuner training course so that I can properly tune the Sniper on the Travelall. I asked the IT guys at work if they had any decommissioned laptops I could buy, and they just gave me one they were going to e-cycle. It’s a 2021 Dell that’s got plenty of horsepower to run the Sniper software; it was gratifying to load the config file and see it in full color on the machine. From what I’ve seen in the videos so far, I’m probably going to have to spring for an extra cable to connect the laptop directly to the carb in order to make tweaks in real time.
