Thanks.

Well... I can describe what I do but I'm not exactly certain that it is the right way to do it. It works for me though.

First off, I don't rely on the solder for the mechanical connection. The only thing I'm using solder for is to back fill the connectors to help prevent corrosion.

Basically, I trim the sheath back to fit the fitting. Double crimp the fitting in place using large crimpers. I drape the wire over something allowing the open side of the fitting faces up. I heat the fitting with a propane torch until it becomes hot enough to melt the solder on its own. I back fill the fitting until full. Allow the fitting and wire to cool on it's own... then heat shrink. I've never had a failure using this method. I have had fittings fail (typically the cheap copper "crushed tubing" fittings).. so use quality components. When working with this big stuff... keep in mind it can/will carry a LOT of current. Don't cheap out on the cable or fittings. The cable I use is US made Flex-a-prene. The fittings are different brands (such as T&B) but I make sure they are thick and made in the USA. I've had the cheap/thin copper terminals snap off.. makes for an interesting show when it finds something grounded.

Anyways... I'm sure there are better/proper ways.. that's just how I do it. Before I got the crimpers, I used a modified C-Clamp and before that, I used a 4# hammer and center punch. Just make sure the fittings are tight and use quality heat shrink. I found 3m adhesive lined heat shrink on ebay for cheap. I got 4' sticks of 3/4" for $3.50 a stick (NOS).

Now if you want solder only joints on these big cables... youtube has some decent videos showing the process. It is fairly similar minus the crimping. With the enclosed lugs, guys fill the fittings with solder first.. then place the wire into the filled lug while heated. Hold it in place while the solder cools and wicks into the cable. On open end lugs, you just slip the lug onto the wire and fill the wire/lug slowly from the open end. Just make sure that the wire pulls the solder in instead of just laying solder on the surface. I find that small diameter solder works best.

Ordered all the parts for the front brake rebuild. New master cylinder, all rubber lines, pads, rotors, inner and outer wheel bearings, and wheel seals. Also ordered a copper/nickel tubing kit as I've got some hard line to replace. Probably going to order caliper rebuild kits while I'm at it.

Everything will be here sometime this week. After that, I think all I'll have left is the drive shaft. May have it rebuilt. I'll have to check it out first but all things considered, may just go on and have it done. I've got a local driveline shop that is dirt cheap and only uses Spicer parts. Last time I had one done (new joints, carrier), it was just over $100 out the door.

Anyways... getting close to rolling again!

Got my power cables routed finally.

Last cable made..

No good way of bolting it in.. but ties should be fine.

What will be the main power stud for the engine bay..
IMG_20180213_170517335_HDR by acidburn02zts, on Flickr

Which will replace this "extra" solenoid ford likes to use. It functions like a power stud except it has one wire on the other side that when triggered, sends power to the trigger wire for the starter solenoid. Its somewhat pointless. I'll be replacing it with a standard bosch style relay to send power to the starter solenoid trigger. The stud will be the main which will have the power for the underhood junction block, power for the bus body, and the main charge feed for the alternator.

All that is left is to hook up the grounds. Waiting to button up some small stuff before putting power to the whole system and turning it over for the first time after all the work.

Brake parts will be in by Friday. Looks like we are ahead of schedule for once.

I think you've replaced or gone through everything possible on that Goshen. Impressive, and in record time.

This oil cooler is the bane of my existence. Got the electrical connections buttoned up yesterday and fired the bus for the first time after all the work.

Oil pressure came up quick.. 40psi at idle. Belt drive was running true... no odd noises.. no leaks from the water pump. At this point, it had been running for roughly 30 seconds. Then I remembered that there are 2 parts to the oil cooler and I only knew the gaskets weren't leaking.

Glance under the bus and oil is going everywhere... a stream roughly the diameter of my pinky @40psi coming from one of the oil cooler o-rings. Ran around and shut it down.. still registering 40psi on the gauge at that point.

Dip stick is now dry... roughly 1.5-2 gallons of oil on the ground @$26 a gallon.

Cooling system is drained again... waiting on another set of o-rings and gaskets.

On a good note, everything else seemed to be doing good. Lol

I certainly hope so. Lol

Well, while waiting on gaskets/seals to get here... figured I'd finish up some little crap.

Finished wiring up the gauges and such..
IMG_20180219_222032379 by acidburn02zts, on Flickr

I really like the lighting... and they dim with the switch which I wasn't expecting.
IMG_20180219_222108310 by acidburn02zts, on Flickr

Since there isn't a factory radio in dash.. I used a radio harness to wire in the gauges. Worked out great and since they are LED back lit, no worries on power draw. Everything is now tied up and tucked back in the dash with the cover plate back in place. Can't even tell. I will be putting in a simple radio but it'll go over head.
IMG_20180219_221824624 by acidburn02zts, on Flickr

After buttoning that up, I decided to run an additional engine ground back to the batteries. The block has 2 grounds coming off of it from the factory. Both used to go to each battery. Now one of them goes to the body.. one to the frame. While cranking the engine over the other night, it didn't seem to spin as fast as I thought it would with the fancy starter so I figure it is due to grounding. I decided to run another run of 2/0 from the back of the passenger cylinder head to the battery frame ground. Should fix it if it was an issue. Don't get me wrong.. it started great.. just didn't sound as fast as others I've heard with the same starter.

Well.. thats the end of progress for this 70F evening. Maybe more tomorrow if rain holds out. I've got all of the front brake parts now along with wheel bearings and some hard line to replace.. we'll see what happens.

Another nice evening so out in the drive again.. Rain is about to set in for the remainder of the week but I managed to get a little done.

Decided to start on the brakes... got the driver's side pulled apart.
IMG_20180220_221233174 by acidburn02zts, on Flickr

Old rotor/hub assembly..
IMG_20180220_221238889 by acidburn02zts, on Flickr

Unbolted the rotor from the back side of the hub and separated...
IMG_20180220_222215943 by acidburn02zts, on Flickr

IMG_20180220_222327454 by acidburn02zts, on Flickr

Stripped the hub and prepped it for new bearings and grease seal.
IMG_20180220_223204186 by acidburn02zts, on Flickr

No cheap crap here...
IMG_20180220_224629091 by acidburn02zts, on Flickr

New rotor on... new bearing packed with fresh full synthetic grease and new grease seal installed...
IMG_20180220_225327269 by acidburn02zts, on Flickr

New outer bearing packed and pre-load set.
IMG_20180220_231623197 by acidburn02zts, on Flickr

All exposed surfaces cleaned and painted with satin black caliper paint.
IMG_20180220_232303838 by acidburn02zts, on Flickr

Didn't want to get rained on.. so I slid the wheel back on and a couple nuts... cleaned up the mess and called it a night. Taking the caliper to work with me tomorrow so I can rebuild it. All that is left on this side is to re-install the rebuilt caliper with fresh pads and a new brake hose.

More to come.
