Yeehaw! It won't be long till I'm cruising in my shiny new '85 F-250!

Zigg came through big time and got me a bellhousing!

I need a clutch fork now, and probably a slave cylinder. Will those parts from a big block F-series of the same era with a T-19 work? I ask, because I imagine I'll have an easier time finding them from a junkyard. It seems once I say "diesel" around these parts, the conversation with the parts guy ends pretty quickly....

Also: is it easy enough to install the release fork and slave cylinder AFTER the bellhousing and tranny are in place? Or is this something you definitely want to do before hand?

do yourself a favor and get a new one from the dealer. these clutch forks are a wear item. I know the throw out bearing on the T18/19 is smaller than the ZF, so I'd say the fork is prolly different. while you are there, get the number from the "parts bin" in the articles section for the greasable TOB. Do the job once and you won't be replacing the firewall in the near future. Its easier to put the fork in before installing the trans.

Alright, yeah, sounds good. New fork indeed: I don't wanna be dropping the tranny every other weekend...

More questions!! I figured I'd just recycle this thread a bit more, as it pertains to my situation.

Luckily we have an automotive shop on campus here, which is a block away from the residence parking lot where my truck sits. They're gonna fix my bellhousing for free!!

I've already drained the t-case and tranny fluids, but I'd rather just clutchless drive the truck to the shop than get a tow truck. Sound safe, or should I dump some new fluid in before making this trip?

spend the money and tow it in. if not, fluid is a very good idea. save a few bucks on fluid and spend a few hundred in hard parts for a rebuild later from oil starvation...now that's economy!cookoo

If you can get somebody to push you in neutral, that would probably be OK for a short distance.

The tranny would probably be ok for a couple blocks, but the t-case has very little oil in it, and a small pump which is only working when the driveshaft is turning, and it's not all bearings in there, there's some brass bushings which probably wouldn't be happy to be oil starved with any kind of load on them.

I'd get it towed as well, or maybe just buy a box (24) o' beer, and then bet the rest of the guys in residence that they couldn't push a truck that size that far, see what happens. You might get it done...

Are you gonna do the clutch too while you're in there? I didn't even think about it, but I also got a "balanced for the 6.9" surfaced flywheel sitting here too you could have had for next to nothing... Doh!!

Going to inspect the clutch and friends, and ensure someone around town has one in stock in case it's needed. Haha, hopefully I won't be coming for that flywheel out of need!

There's a nice little hill unfortunately. Although, I could just drink the 24 to myself, not put the oil in, and drive it straight through the shop doors... haha, I don't think I'd be worrying about bushings...


If it were say 30*F out, how long would you all figure it'd take an IDI to warm up? Idling, from a dead cold start. I think I waited for about 15 minutes the other day, and the needle had barely moved up... thermostat time?

460 stuff and diesel 4 speed clutch stuff is fully interchangeable, I have swapped the hydraulics between my two trucks a couple times, and the clutch in my diesel is the spare that I had come into for free for my 460 truck 3 years ago. The hydraulics are also swappable between a ZF and a 4 speed, both 460 and diesel. The hydraulics on my 460 are, well, the master is off of my diesel, line is from a 91 diesel, slave is from a 97 PSD truck... LOL.
As for warming up, 15 minutes and still no heat is about right if it's just idling.
Mine kicks down off of high idle after about 10 min or so, but, it has a 205 degree thermostat in it, and I run an e-fan for the winter.

Whoa there buddy. :eek: That's thinking outside the box. Most that have left the box have come back poor. You know the pastor's words, so I'll spare you the sermon. Good luck!

Been running it a year like that with no issues, it was in there when I got it, I only recently had it apart when I changed the water pump.
Running temp on the highway is usually 190-195(that big rad is very efficient), even last winter when I was running no fan at all. Which is still cooler than most of the diesels I work around, Most of the stuff I'm used to runs around 200-215, but, I also don't work my truck very hard very often, It'll be getting a 195 stat in the spring, as it will be pulling next summer, and a turbo is in the works. If I don't drop in a CTD instead...
