SMF bolt size?? Sources?
The machine shop is finally ready to balance the rotating assembly for my 7.3 IDIT! But they lost the (9?) bolts and spacer for bolting the flywheel to the crank. Exactly what bolts do I need for a Single Mass Flywheel, and where can I get them? And where can I get the thin metal spacer? In...- Fision

HP/Torque- When things start breaking...
Generally speaking, Components have an: A) “I can do this forever:)” happy spot; B) “I can only do this for so long...:bail” tolerance, and a C) “l quit:angel:!” As it applies to our IDI engines and old Ford trucks, What have you experienced/read/heard? Some of the IDI components I...- Fision

Rocker arms- replace or keep?
Getting closer to putting my 7.3 together. A friend strongly recommended replacing the rocker arms “just because...” My used ones have 200k miles on them. But it seems I rarely hear of problems with IDI rockers (the new style). How often are rocker arms a problem? How do I check for wear “to...- Fision

Air-water CAC/intercooler on an IDI?
Anybody know of an air-water CAC/intercooler being used on an IDI? Or even a 7.3 Powerstroke, since it would be a similar fit. If so, what model cooler and what style turbo setup? Some of the air-water setups are quite compact and would afford a shorter route from turbo to intake. I would also...- Fision

Cavitation PM during rebuild
Has anybody coated the interior of their block coolant jacket as added protection against cavitation? There are a number of hard curing sealants that seem like they might help with this problem. My build project got derailed for a year so I’m having trouble finding some of the products I read...- Fision

Has anybody Bushed turbo con-rods
I have run across many references to bushing turbo con-rods to fit NA pistons, but all in the third person/theoretical. Has anyone done this? Any recommendations on what bushings to use? Hopefully I’m only a couple weeks away from getting this done.- Fision

Acceptable cylinder wall thickness
So I got the results of my sonic check today and the thinnest spot is .239”. Since the test is a spot-check of many points there may be spots that are thinner. The cylinders are consistently thinner at the tops, and are well over .300” as you travel toward the bottom. I would need to bore...- Fision

Balance the rotating assembly on a rebuild?
I’m rebuilding a factory IDIT (201k miles) to replace the ailing 7.3n/a in my ‘92. *Should I have the machinist balance the rotating assembly?* Unless a problem comes to light most all the internals “look” good, except for two of the pistons which have a little deterioration of the top edge...- Fision

Stick it to The Man!.. named Allison... which is a girl’s name..?
I need (ok:rolleyes:, really want) 6th gear unlocked on my tranny and need help. I just purchased a 1996 IH 4900 with mechanically injected 250hp dt466 and Allison md3060. So far so good, right? EXCEPT—the Allison has the 6th gear locked out electronically :mad:. Apparently this is a pretty...- Fision

Considering ‘91 idi van: suggestions?
I own a ‘92 f-250, so I have some idea of what’s involved with maintenance on the idi, my bigger concern is access with the van. How hard are routine maintenance items, including glow plugs? The van is a long way away, so before I commit to looking at it I want to know if I should be considering...- Fision
