    Amsoil synchromesh in ZF-5

    Seems to me it's closer to atf then 5w30. Being a filtration nut, you probably know more about oil and the exact specs/viscosity breaks, but pulling the specs from pennzoil's site for kinematic viscosity seems to say something different. fluid KV@40° KV@100° dex 3 39.1 7.8 synchromesh...

    Amsoil synchromesh in ZF-5

    Synchromesh has the viscosity of an atf, but without all the additives and frictions modifiers that are present in modern atf. ATf is a neat fluid for it's application, as it needs to be a lubricant, but it can't lubricate so well that the clutches slip when they're not supposed to. I've also...

    CDR question - 1988 International S1600 7.3 idi (dump body)

    That's correct. The drop is smaller because it's deeper where the sump isn't by a couple inches. The fords had to clear the crossmember so the pan hugged the block more. I can take all the measurements one would want from either front or rear pan. They look slightly different, but that's just me...

    CDR question - 1988 International S1600 7.3 idi (dump body)

    One of mine is front, the other is rear. Not real sure if I'd call it a sump, though, It might be 2 inches or so difference between front and rear for the sump part. Definitely isn't as pronounced as the truck pans' sump that's for sure. Not sure if that helps you, or if it would be different...

    CDR question - 1988 International S1600 7.3 idi (dump body)

    Your cdr is right in the center-left of your picture. It's painted orange and is between the air cleaner inlet and the firewall. The hose from the valve cover goes to the top, and the bottom goes right behind the intake. It could be junk, or your engine could be wore out. Easier to replace the...

    Self oil burning

    My project has stalled. In order for the pintaux nozzle to work, the idle jet has to be pointed at the glow plug, and how a normal idi injector is spun to be tightened doesn't really allow for that. I've got an idea in my head that would allow it to work, and I've found engines overseas that run...

    Self oil burning

    Yup, ricardo found that a dish below the pre-chamber hole that allows it to swirl and hold the heat, which will continue to burn throughout the rest of the combustion is best. All of the prechamber, hole, and combustion chamber sizing stuff is based off ratios and fuel levels. The less fuel you...

    Self oil burning

    Fuel is getting on the precup anyway. Difference between the two is that it's on the bottom vs the sides. To run a DI nozzle in an IDI the glow plug has to be deleted, or it will be torched and delete itself. The DI nozzle will start easier because it better atomizes the fuel compared to a...

    Self oil burning

    One is a pintle nozzle and the other is a multi-orifice nozzle. Both are diesel nozzles, but they're pretty different design. Kinda like peas and carrots, both are veggies but definitely not the same.

    Need help: odd fueling issue

    Yes, There is a vane style transfer pump that needs to be turning in order to let fuel into the pump. Usually, if the rotor is turning, so is the transfer pump, which is why I asked if the rotor was turning. The transfer pump will provide fuel to the calibrated air bleed which will fill the...

    Need help: odd fueling issue

    Are you cranking it at full throttle? Try that and report back. Fuel should come out of the housing while cranking. No fuel out the housing tells me it doesn't have fuel or the transfer pump isn't pumping. Remove the timing cover on the side and see if the rotor is turning while you crank. If...

    Timing at 8.5 or 9.5 degrees BTDC?

    Mine is at 7, NA 6.9 in a school bus. I tested from 6 all the way to 10 in 1 degree increments. Being in a heavy bus, the differences between the tests were pretty noticeable in acceleration, heat, clatter, and black smoke produced. 6 was smokey and seemed to be hotter temps then 7-10. 7 was...

    any 6.9 fuel water separator alternatives?

    My bus (1984 IH 6.9) has 2 filters, a primary/water separator mounted on the radiator support, and a secondary mounted on the engine. Both are factory IH equipment with primary being wix #33439 and secondary being wix #33811. The primary is 1"-14 and the secondary is 7/8"-14. I've replaced the...

    Recirculating Return Line Fuel?

    Oil would be a better lubricant then ULSD. But wmo needs to have a lot of filtration done to it to be clean enough to be considered a fuel IMO. If it's not clean, you'll likely do more harm then ulsd even with oil's better lubrication properties.

    Testing fuel pressure

    I tested mine at the bleed orifice, if you still have it. A simple vac/pressure gauge for a gas engine and about 10 foot of rubber vacuum hose. Harbor freight had them for less then 20 bucks last time I walked through the place. Zip tie it on the barbs if you're worried about the hose blowing...

    Which fuel filter?

    IMO I wouldn't run a diesel without a water separator. You can get a racor aquabloc and filter head cheap off ebay, and those are 99% efficient at catching water. Maybe these old engines with cheap fuel systems it's not important, but run water through a modern truck and you've cost yourself...

    Recirculating Return Line Fuel?

    Not huge. But the pump will suffer longevity issues over time. Cold fuel is a better lubricant then hot fuel, and the fuel temp will increase with time. The bigger issue with this is not purging the air from the system. I screwed up my check valve placement on the bus(long story) and basically...

    Buying 85 IDI ATS turbo motorhome!

    Those slots allow gases created by overheating the friction to escape. They also play a role in harmonics and squeaking. Cheap pads won't typically won't have them. Why napa's "premium" pad doesn't have it, I don't know. We install a lot of napa pads, and I've never liked their premium line...

    1989 S1600 x Uhaul truck 7.3 IDI

    It might run with the key off too. I'm not sure, I haven't worked on one in a while. There should have been a sticker or something above the visor detailing the start procedure.

    1989 S1600 x Uhaul truck 7.3 IDI

    It likely is a standard hydroboost system, but with a back up electric pump in case your power steering pump fails. Pretty common on a lot of your juice brake MD stuff. There is a pressure switch that turns on the light when there is no hydraulic pressure, it also should come on and stay on if...

    Self oil burning

    Interesting. I'd have to agree that the proper piston design would lower compression while keeping the crown as near as possible to the deck surface. Not sure that I'd want a piston with the combustion space as wide as that 6.5 design. I think I'd want something more along the lines of stock...

    7.3L IDI Industrial Motor Mounts

    Not really. It's on the spare engine. I've considered selling the spare engine, but then I'd be without, and it took me a while to find this one.

    7.3L IDI Industrial Motor Mounts

    All of your medium duty options, so allisons, spicers, fullers, etc. It's an sae2 housing, so anything that's sae2 sized will bolt to it, so long as your input shaft depth is correct. Some use an sae3 housing, and there is an adapter ring installed then to go down from 2 to 3.

    Both mounts are on the flywheel housing though. And you can see the front mount bracket in both pictures too.

    Well, look at the flywheel housing on the back of the engine. They can use something like this. Or like this.
