So I got myself a delco 22si hp and was curious how to hook her up. Should the voltage regulator be changed from the old generator or do I even need it? The alternator has 4 terminals battery, ground, R and a blank one. 

I went there and looked at a b81 last year they have a huge selection of old trucks. 

Don't have a big enough socket to torque it yet but thank you for the heads up. 

Yes the linings look to be soaked I read up on some remedies. One being brake clean and a propane torch. But someone loaned me the appropriate tool and came out pretty easy. Got a good part number so next week it can go back together. Is there a torque spec for the large spindle nuts and axle shaft bolts?

Got everything apart today with moderate language. How do I get the seal and bearing out of the rear of the hub ?

Alrighty I guess there is no quick and dirty for this one. I will just make up some cribbing for her to sit on for a couple days. 

Looks like sitting for a while killed a wheel seal crd73 axle would anybody have a part number?

I put that pump fx  suggested on my 401 works excellent. Made a block off plate for the fuel pump hole wired it up and let her rip.

Okay got her running on the electric fuel pump a real thing of beauty

The 80 series trucks had military style fenders where the rest had the rounded fenders. Look long and hard at the frames and sheet metal, if it has a double or triple frame look for spread from pack rust and rot both can mean serious time in repair. The rear of the cabs love to rot out and make sure the fenders are solid. Vent windows are top dollar good glass can be a big plus. If you expect a decent road speed check the differential ratios. 6 to 7 ratios can get you around 50-55 with the low rpm Mack diesels. I am sure somebody else can chime in with more pointers. I wouldn't be afraid to buy the gasser it can always be repowered but keep in mind parts are getting harder to find for any of the old power plants

I was planning on going to a single wire alternator to simplify things a little. Read up on here about people using a delco 25si I think it was

I did the cheap and dirty just bought a resistor to wire before the ignition. Got the fuel pump in today so that will be part of the weekend projects. I plan to flip it to negative ground, just hook the battery up accordingly flip flop the coil wires? 

The pump is accessory belt drive not sure how much room you have to play with

After digging for a while I came up with this kit https://brillman.com/product/b255ls-12-volt-negative-ground-delco-distributor-electronic-ignition-kit/

I have a spare garrison draglink control valve and fluid reservoir if you want to go that route. I also have some sort of power steering pump that came as extra parts but I don't think it actually goes to the garrison system.

alrighty, I see they have a selection of kits. somewhere along the lines of a 6cyl gm should do the trick?

So looking into the 12v cool points and condenser I found there were systems with built in resistance and external resistors. I am thinking non resisted circuit, anybody know some part numbers to do this conversion? Being born into the age of fuel injection has its downfalls when working on equipment that is twice my age 

Yeah both positives linked together. The regulator had 6v stamped into it as well

I once saw an r model dump truck with 3 the regular 6 speed with a brownie behind it. Figured it had to be for creeping or a highway gear

We were just talking about doing that today, would be quick, easy and pretty cheap

Got the pump apart AC model D diaphragms are cracked. Going to hit eBay and google for a rebuild kit or replacement. I am thinking I could find a 12v points condenser and coil at napa if not tractor supply thanks for the heads up

Copy that I'll grab a voltage reducer and take the pump apart

The one 12v battery did just fine wasn't quite sure if it would bother the ignition though

Okay got it running today, not sure how much clatter to expect from an old flathead but she holds good oil pressure and purrs like a cat. There was a small weep hole shitting fuel out on the fuel pump which a small machine screw plugged quite nicely

They told me it was 6 didn't notice any markings on them will have to take another look. They have 3 holes to top off battery acid
