    Ford Says "Hold My Beer"

    Tearing out the dash on a 1989 F350 Lariat Centurion conversion today. It's a short body crew cab base with one tank. Found this tank switch with the selector electrical tapped to the 1 selection. It was buried deep behind the dash, right next to the clutch interlock connector with the bypass...

    1989 ZF542 on 7.3 Clutch Interlock

    Attached is a extract of the interlock from the Ford service manual for 1989, all E and F series. It shows two clips, one orientation and one plastic retainer, that hold the switch in place. New clutch masters don't come with a clip or retainer, nor do new switches. The new master does come with...

    7.3idi Fuel Check Valve Recommendations

    Getting rid of the mechanical fuel pump on my '90 7.3idi. Picked up a Holly Red pump and Racor 500 water separator/filter/heater, which I'm installing on the frame rail at the tank. Going to install a Holly 4-9psi regulator and gauge on the plate that previously held the OEM separator. The...

    7.3 Diesel Transmission Adaptor Plate

    I'd be willing to pay for your time and shipping. I ordered one that's on the way, but I don't know if it will fit. Once it's in I'll mount the starter and see how it works. Is the a PM feature on this forum?

    7.3 Diesel Transmission Adaptor Plate

    Appreciate the confirmation! This engine transmission swap/conversion is several "first's" for me, that the donor and mod trucks are 34 and 35 years old, with inconsistent listings and upgraded parts bolting on only adding an unexpected quandary. Thank you.

    7.3 Diesel Transmission Adaptor Plate

    To keep a long story short, I've found myself in need of the adaptor plate for a 7.3idi to ZF542. I know the part number is 1800475C1. Doing a search that includes the engine/transmission year has limited options. That said, doing a part number only search shows these plates listed for 88-91...

    Solid vs Elastomer Harmonic Balancer- Which is Better?

    The one pulled off has a rubber middle between steel. I'm going with the solid, no middle rubber one. Thanks for all the input.

    Solid vs Elastomer Harmonic Balancer- Which is Better?

    Understanding just enough to get myself in trouble consistently, I'm hoping someone with a better understanding of all the competing harmonic imbalances can help clarify something. I searching for a replacement balancer for a 7.3idi engine that I'm adding a modified 088 ATS turbo that is...

    '90 7.3idi Harmonic Balancer Fit Years

    Can't say I understand why they would delete the earlier years, unless the new model's are of better quality. Heading out shortly to a chain store to compare. The only ones listed for 88-91 are also listed up to 97, so obviously interchangeable. Which only opens up a Pandora's Box that will now...

    '90 7.3idi Harmonic Balancer Fit Years

    Been searching for a new harmonic balancer for a '90 F350idi. Going through online parts suppliers it appears as though the '88-'91 model parts are scarce. That said, '92 and up are everywhere. I'm wondering what's the difference, if any. For instance, I had to get a new clutch/slave assembly. I...

    8th Gen 7.3 IDI C.O.I?

    Being a Sparky by trade I make my own cables and harnesses out of double wall marine heat shrink and press copper lugs. Here I thought I was just waiting for parts and you mentioned autozone. Never even considered trying to source the brackets and tensioner from a chain retailer. Bet I could...

    8th Gen 7.3 IDI C.O.I?

    The worst will be finding the parts as wiring and mounts are only available from donors. Salvage yards are picked clean and everything else is running.

    8th Gen 7.3 IDI C.O.I?

    I'm drooling. In truth, I had given up on the C350 years ago, and believed all that was left was for me to finally "get over it" and sell to someone else. But then the opportunity literally came out of nowhere for the free donor engine and transmission. Unfortunately, as with most freebies, it's...

    8th Gen 7.3 IDI C.O.I?

    That is an awesome mod. Where did you source the intake from and what model intercooler?

    8th Gen 7.3 IDI C.O.I?

    Mine isn't a PSD. Gen 8 are the last IDI non-turbo. When Centurion did the Bronco conversion they added an ATS 088 turbo to the engine with all the interior mods, but it still has a V belt system. As I understand it, the only intercooler kits are for serpentine belt, which means finding a 92-97...

    8th Gen 7.3 IDI C.O.I?

    Waiting on rebuilt turbo, injectors and pump to arrive and am looking for a decent aftermarket cold air intake. Saw one from S&B Filters and was wondering if anyone had experience with those, or has a different recommendation? I haven't found an intercooler kit for a 7.3 V-belt system, so just...

    Aries Power Drop Mod for OBS 7.3

    I've heard the door switches the negative side of the lighting circuit. Besides, I'm going to wire the running boards to a fresh circuit, then drive each side with a relay that will trip if either front or back door is opened.

    Aries Power Drop Mod for OBS 7.3

    I have an '89 Centurion and am looking for a powered retracting running board. It's an F350 idi with a Bronco clip and 2 rows of seats. I put a 4" 1 ton Superlift on it, and am planning on swapping the 35" tires to 44's. The problem then will be the 3' from the ground to the step. Aries makes a...

    My 7.3 IDI just blew, need to find a rebuilt engine.

    I have a '89 Centurion. It has over 270k miles, I am the 4th owner. Had a under hood flame out, and I'm sure a head gasket blew. The injector pump was in need of attention the day I got it. I don't have the time, place, or experience with diesels to do a rebuild myself. I've heard a lot...

    need advice on IDI to PSD Swap

    I do understand. I've been a Ford man my whole life. I still wont get rid of the Ford running gear, it's been the most reliable 4x4 and towing trucks I've ever had. That being said, I can't argue with 500k minimum per engine swap. I consider myself lucky when I can squeeze 300k.

    i have a '89 Centurion with 7.3 idi, ATS turbo. It has a 4x4 auto 3 speed with OD, I'm running 35" tires. I want to drop in a '97 PSD. It came off a 16 passenger city bus that was vandalized. I understand the seller has all parts, throttle, wiring harness, and i believe oil cooler. I...
