    The installed breathers.

    I ran into a bit of a space problem when re-installing the left fender. I had re-routed the brake lines when I replaced the Chrysler master cylinder with a Wilwood version and my previous location for the Bussmann relay block was usurped. I made a new, much smaller trapezoidal base that would fit vertically between the master cylinder ports and a new mounting bracket. I guess it turned out ok. I still have to deal with the wiring in front of the welder and passing over the grill.

    This was my old base that I had repurposed from some ancient data logger stuff.

    You do nice work, Sir. Be careful of the welder around those fuses & ,Blocks , & inlines. With me , welders & adjacent electrical don't mix well .:lol:

    Finished up the hand throttle linkage this afternoon. The Pro-Flo 4 throttle body is quite a bit different than the Pro-Flo 2 version that was on this before. I had made a roller system that acted directly on the throttle body for it but it wouldn't fit on this one. I had also used my existing twist lock cable that did not have the fine screw adjuster the Buyers version has that came with the welder. It worked but wasn't too precise setting the speed. New version using the Buyers cable:

    And the return spring tension adjuster

    I'm not sure I believe it, but a new coil wire, hook the battery up, and add about another 12 gallons of gas and this thing is ready to fire. Well at least try to fire-----

    With the pro-flo do you have an input for a high idle with A/C on? And could you change that value to a generic weld speed if needed?

    On the tbi I got I have 4 idle combos they should give a governed rpm for several high idle targets. It'll be nice if I get a pto ice cream maker.

    John,
    If I may say, you are a the upmost Master Fabricator/ Builder that I have had the privilege to follow since I joined this Forum.
    Your entire Build & Workmanship is Bar none, IMHO . Here's to Good Luck on the Start - Up . :bow:

    On Pro-Flo 2 you could set the idle anywhere you wanted with a couple of keystrokes. On 4, with its self-learning ability, its a bit more complicated but it can be done. With the welder, you need the ability to finely adjust the voltage (engine speed determined) to whatever you are welding. It also has 110V output which requires an even higher idle. All in all, I don't want to mess with the programming for this.

    There are a few things remaining to be addressed, including the left side exhaust skid plate mounting and the seat belt reel mounts, but with another 10 gallons of gas (so the pump has gravity feed for start-up), it is ready to go. A lot of stuff crammed in a small space but at least one doesn't have to tear half the engine apart to change the spark plugs.

    Do you have friendly shop gremlins that dust and clean your engine every night? Looks like art.

    That's as clean as it will ever be--------- A lot of new pieces in there. Only the valve covers were recycled and I'm kind of attached to those-bought them new in 1973. They required a little rehab work.

    Progress on the rear axle project that has been on the back burner for a couple of months.
    Jpet's spindles as received. These spindles are machined for double Timken Set 47 bearings and the D30 disc brake hubs. I lucked out and found a decent set of the original Dana hubs on ebay.
    [​IMG]

    I changed my mind about how I was going to mount the brakes and remachined the backs so the inside seats into the stock axle housing seal seat.
    [​IMG]

    Seal seat "collars".
    [​IMG]

    I received the Dutchman 4130 flanged full float axles last week. I did a bit of guessing on the length and won. Since the inner axle seals were already installed (prevented the tape from catching the side gears) along with the ARB/gears and I had no desire to take it back apart, the tape was bottoming on the spider gear cross shaft. I couldn't find a measurement for the width of the spider shaft block. The spider shaft is 20mm and I scaled the block width from the drawing in the manual and subtracted that from my lengths.
    [​IMG]
    The spindles extend to about half the stock seal seat depth and I made press-in collars to fill the rest. The Seals-it seal lips span the filler collar and the 2" diameter recess in the back of the spindle.
    There was a bit of internal debate as to whether to turn the axles down to clear the spindles or to open up the spindles a bit. I went with the latter and bored the spindles another 0.015" to get the Dutchman shafts through. A better arrangement if those shafts ever need replaced and the 4340 spindles are probably still 50% stronger than the stock versions. I had Dutchman machine the shafts at the spline major back 6.5" for the inner axle seals and polished both that area and the area at the rear of the spindles for the outer axle seals.

    Those spindles custom made? They are beautiful.

    Jeff Petrowich (jpet on the 2A Page) machined them out of pre-hardened 4340. Jeff is not only a really great off road pilot, but a very talented machinist. The pre-hardened 4340 is pretty tough stuff. I didn't think my old HS boring bar bits were going to suffice so I ended up buying an indexable carbide version for this. The spindles use the larger set 47 bearings for both sides of the hub so there isn't the usual step down in the spindle. That was possible because both set 47 and set 45 (stock disc brake Dana 30 bearings) have the same outside diameters.

    I sort of hybridized the spindle nuts. I used the Chevy/Ford inner nut with the locking pin with the corresponding lock plate and a modified Jeep hex nut with set screws for the outer. I was initially going to tap the Chevy/Ford outer nut for set screws but those suckers are REALLY hardened.

    I wasn't ever very fond of the bent tab nut locking scheme. Cheap to manufacture for sure but sort of a pain in the posterior.

    No way! I understand now, so these spindles use for inner and outer the inner D30 disk bearing. Brilliant. This fixes the problem when boring the stock D30 spindle wall thickness to accept full float conversion.

    the material alone had to be expensive..

    What method are you using to retain the axle shafts?

    ARP 642-1750. These are the same bolts I used with the drive flanges. The problem that arose is the one piece axle flanges are 1/2" thick, about twice that of the drive flanges, and that left the flange/hub interface right at the top of the threads on the 1 3/4" bolts. The 2" bolts would require cutting a couple more threads and thus ruining the smooth transition from threads to solid shank. The get by this, I'm eliminating the stock washers with the tapered seats that come with the bolts. Dutchman countersunk the flange bolt holes so those bolts seat flush on the flange anyway. I still think the 8720 bolts are stronger than any studs you can get.

    Is that outer nut just a stock Jeep nut drilled & tapped for set screws?
