    Can You Surface IDI Cylinder Heads with Sandpaper?

    So, I surfaced some cylinder heads this weekend in the garage quickly and accurately with some 60 and 80 grit ceramic sandpaper (Don't use box store sandpaper! Get Hercules ceramic sandpaper from Harbor Freight), a feeler gauge, an OEM Tools 2' machinist straightedge, and an inexpensive granite...

    O/T Spare Tire Hardware 1991 F350 DRW

    Can anyone tell me what I'm missing as far as spare tire hardware for my 1991 F350 dually? I think I need a bracket to hold the top along with a wing nut, but should something be holding the bottom of the wheel, too? Thanks

    Remote Fuel Filter Recommendation?

    I need to do a few jobs under the hood - new fuel return lines, new valve cover gaskets, new glow plugs - and it would be easier if the factory fuel filter setup was out of the way. Anyone have a recommendation a kit for relocating a filter/filters to the frame? I'd prefer to buy everything...

    Battery Cable Routing...

    Battery cables on Project Brownie were looking rough so I replaced them with 2/0 cables and military terminals. After I completed the job, I realized that I had flipped the batteries around. The terminals had been closer to the firewall originally but now they're closer to the radiator...

    Wobbly Alternator Belt - Cause?

    Ok, so I have a 1991 F350 7.3; it has v-belts. The alternator belt was wobbly so I decided to change them out this weekend when I did a coolant flush and radiator hose change. Anyway, the alternator belt was still wobbly with the new belt and I got it nice and tight. It's bad enough to where...

    Front Hub - 1991 F350 4x2 Dually - How To Tell If Wheel Bearings Are Bad?

    So I brought Brownie to the shop last week to get it aligned. They said they couldn't align it because it was too sloppy and said I needed new wheel bearings. I bought new wheel bearings and races, but I'd rather not change them out if I don't have to. I'm assuming I can just remove the hub...

    Shocks for 1991 F350 DRW Rear Wheel Drive Stock Height - Bilstein 5100?

    I'm in the market for some shocks for Project Brownie and had hoped to get Bilstein 5100, but unless I'm mistaken, they're not available in this configuration - 1991 F350 DRW Rear Wheel Drive Stock Height. I'm seeing 4x4 shocks and lifted shocks, but nothing for stock height RWD. Anyone have...

    1991 F350 Crew Cab Diesel Dually Build - Project Brownie...

    After I sold my previous project truck (Brutus - 87 F350 CCLB DRW 4x4 7.3 IDI-T ZF5) it was only a matter of time before I found another one. Anyway, once I moved home to Texas, I found a nice 7.3 IDI powered crew cab dually. It's a 1991 XLT Lariat, 7.3, ZF-5, Sterling 10.25 (with 4.10's and...

    Tires for 1991 F350 DRW - 235/85/16 or ?

    I'm in need of a set of new tires for Project Brownie, a 1991 F350 CCLB DRW 7.3 ZF5. I'll be using stock steel wheels, truck has 4.10 gears, will be used for towing. Not too worried about miles per gallon. Will spend some time off-road picking up project cars, so I'd prefer something with...

    Low Silicate Green Coolant - Which One Are You Using?

    I need to flush the coolant/antifreeze on old Brownie, my '91 F350. Truck is new to me and I don't know how old the coolant is, but it's green ethylene glycol and the truck has been off the road and used around a farm for about 10 years. Figure the coolant is likely 10+ years old. I plan to...

    4x4 Conversion - Hole for Transfer Case Shifter?

    1987 F350 6.9 (now 7.3 IDI-T), ZF5. Originally 2WD, but has a 4x4 ZF5 and swapping in the 1356 (manual shift) next weekend. Any ideas on where to cut the hole for the transfer case shifter? I'd rather not just torch a hole in the general vicinity. Thanks

    Borg Warner 1356 Transfer Case Rebuild

    I'm rebuilding a BW 1356 transfer case for Project Brutus; figured I'd post pics and details here in case anyone was interested. I picked up the TC several months ago from a guy in PA who parts out a lot of trucks. He had no idea on the internal condition. Anyway, now that the 7.3 IDI and ZF-5...

    Pulling Hair Out with ZF5 Install - What's the Trick to Installing One?

    Ok, so I installed the rebuilt 7.3 IDI in my '87 F350 a few weeks ago and now I'm trying to install the ZF5 that I rebuilt. I'm doing this in the driveway, by myself, using a transmission jack. I'm using a Luk clutch/pressure plate/flywheel kit. I got the trans lifted up and somewhat...

    Mystery O-Rings in ZF-5 Rebuild Kit?

    Anyone know what these o-rings are for? They came with my gasket/rebuild kit. I'm finishing up a rebuild on a S-47 4x4, and I don't recall seeing these on the disassembly. Looks like the two thin ones are for the shifter, but not sure on the other 3. Thanks

    Install 7.3 and ZF5 Together or Separately?

    Finished the rebuild of the 7.3. It's going in my 87 cc drw 4x4 project truck. Truck doesn't have core support, so I won't have to lift too high. My concern is how heavy the engine/trans combo is together. I have a newer cherry picker and I know it will lift it all, but it will be difficult...

    Is This a C6 Crank Spacer or E4OD?

    I'm going through stuff in my garage to catalog and sell and I've had a few different engines, so not sure which one this came from. I'm pretty sure the C6 and the E4OD transmissions used different spacers; does anyone recognize this one? Thanks

    Crank Spacer - Auto Trans Only?

    Ok, so I have disassembled three engines - 6.9 (manual trans), 7.3 x 2 (both auto trans - a C6 and a E40D) - and have parts strewn all over the garage. I have rebuilt one 7.3 and it's going in my '87 CC DRW 4x4 F350 with a ZF-5, single mass flywheel. The thick crankshaft spacer is only for...

    How to Install Oil Rings?

    7.3 build continues - got the crank in with no issues. Endplay of .005". Main bearings at .002". But now it's time to install the piston rings, and the oil rings are new to me. Is there a trick to install them? From what I can tell, the expander type deal fits behind the ring, and it's got...

    7.3 IDI Cylinder Head - Rebuilt - Locust Grove, VA

    Rebuilt 7.3 IDI cylinder head from a 1988 Ford F350. The engine was running when removed and had only 31,000 miles (it was a plow truck - only used in winter). I went completely through the head - disassembled, cleaned, magnafluxed (checked for cracks), checked for straightness (within...
