Looks like it was held on with one bolt... At least what remains of the bolt. That is going to be fun to drill out.

Looks good! The login doesn't seem to be consistent from page to page though. And when I use the Brave web browser I keep getting some error about enabling cookies when I try to login. Thanks!

Concerns noted... Here is the Volvo unit I got.I had it taken apart to see how it worked as well as to get hydraulic and air piston diameter information. I called the local trucking yards, but all the units they had bolt to the bottom of the transmission. I didn't want to lose anymore ground...

Charlie - Based on my observations.... I don't think my firewall is a issue, but thanks for the reminder.Jake - I have an air assist slave out of a Volvo semi that has been sitting on my desk for the last couple of months. I have dismantled it to figure out how it works.. Looks like the...

Charlie,I plan on welding in some steel tubing on each end so that the bearings have more support. I hadn't thought of using zerks though, I'll have to keep that on in mind. I have noticed that the frame the supports the petals is flexing a bit as well. The hydraulic setup with the commercial...

Hey Blue,I'm wearing the in-cab pivots out (I replaced them with oil filled brass). Forces are a little too much. As such I can't grab the flywheel brake anymore which makes getting it in gear a grinding experience. My thought on the air assist slave is to install it with a pressure regulator...

Fordgirl, I distrust sensors... over time they can drift or read incorrectly. Which then has you chasing your tail. What sensors feed the "running rich" codes? Perhaps Charlie can weigh in. Cj

I really wish you could add more pictures at once...Drat!! Made a wiring mistake in the board after all. And then realized I cut the wrong wire while trying to fix double drat!! But hey for a first try...I upgraded the display when I moved over to the finished board. I got one with a...

Seems it has been a while without any updates... So EGTS. I not a fan of the Edge readers so I created my own. As a reminder I installed 2 K type thermo couples in the up pipes of my exhaust system when I put the transmission in. So here it is in the wire frying, bug smoking, and of course the...

Thanks Jasperrc and 68F100,It was a scramble that last day. And there are still a few loose ends. I need to upgrade the negative/ground wires to the batteries. I'd also like to upsize and reroute the positive wire coming off the alternator to the other battery. Now that warmer weather is...

Another day another post. Sorry - I was in the thick of the install and didn't take as many pictures as I should have. I was putting the intercooler in as the city was adding curb, gutter and sidewalk to the front of the house. I was under a bit a of a dead line to get the intercooler in and the...

So the intercooler piping from the 99+ trucks doesn't exact fit... so back to the old cut and weld trick. Cool side:Hot side cuts. Had to add some sections of pipe.The core support had some existing holes that lined up nicely with with the intercooler so I machined some brackets for the...

Charlie - the clamps are made by Kant Twist. They are available in a few different sizes up to 6 inch. You can get them at travers.com or the ripoff site - mscdirect.com. I use them to hold material while machining.Cj

Hey FatherDoug,Does a big hole saw get you excited like the sawzall? To fit the intercooler on the OBS a pair of cutouts are needed in the radiator support structure. First to get the rough location of the intercooler I placed it in front and leveled it about where I thought it would fit...

When I got the truck the previous owner mentioned that it would shred belts. I took a close look at the belt path, but at the time didn't see anything obvious. And as the truck ran well and was in overall good shape i bought it. Balancer ran true.Well back to the sordid tale of the leaking...

Yes - as the pulley moved forward the edge of the belt would ride up on the side of the pulley which then tore it up. I'm now watching the placement of the belt on the pulley. If I start to see it move again I'll put a new pump in (after I come up with a way to keep the bearing pack from...

What?? No one has any ideas on the assisted slave? Oh well.. I'll have to get friendly with the local semi pick and save yards I guess.Well now that I have a serious transmission, it is time to upgrade the power. 420 ftlbs of torque just seems a bit lame with a transmission rated for 660...

Well, found this: https://www.tbtparts.com/clutch-servo-626639am-p-994.html Seems like clutch servos are much more popular across the pond. I found a reference to Kenworth T680 trucks having an "air assisted hydraulic clutch"...

Interesting Charlie... Can the air pressure be adjusted for a firmer feel? I'll keep that in mind.

Thanks Doc! Now that I have the hang of driving it again... it is a lot of fun to drive. Clutch is heavy, but I have recently become aware of the existence of an air over hydraulic clutch slave cylinder. If there are any heavy duty diesel mechanics out there that have information on the air over...

With all the cutting I did to fit the clutch linkage, I had to come up with a new cover to fit over the hole in the side of the transmission tunnel. Lots of pounding, a bunch of cutting, a bit of welding and here is the new hump. I tried to give it as much clearance from the gas petal as...

Hmm.. just one problem with version 1, I can only get partial release of the clutch. Not even close to enough movement to get close to the clutch brake. After some head scratching, I found that Ford does not use the complete travel of the master clutch cylinder (about 1.6 inches), instead the...

I'm Charles. And unfortunately allergic to cats.

Thanks Charlie... so I have to ask is it Charlie or Charles?

On to the clutch setup.. Typically these transmissions are hooked up with a mechanical linkage, although I have seen a hydraulic setup that bolts to the bottom of the bellhousing on ebay. After digging around under the hood I decided that it might be easier to keep the hydraulic system verses...

The fellow I bought the transmission from picked up a vertical lever/shift tower for me when I drove up to purchase the transmission. As that wasn’t going to work I cut it all up (and down) beat it up with my press and welded it back together as a shortened 90 degree tower.

Sorry to keep ya'll in suspense...I have to apologize for lack of pictures in this next section.. I actually did most of the work described here much earlier in the process – long before I put the transmission in the truck. I knew when I started that the Eaton shift tower was going to be too...

With the clutch and flywheel in place getting the transmission back in was a bit trickier.. with the exhaust down pipe dangling and the engine tilted down as far as I could get it, I managed to slide the transmission up and into place. I used 3 10 inch long 3/8 bolts with the heads removed as...

With the exhaust down pipe fitted I started in on the final assembly. A new flywheel, commercial clutch and pressure plate ready to fit. Sure looks nice in there. This is a 14 inch clutch btw.

Time for exhaust work.. The prior owner of the truck put a 3 inch round exhaust in the truck which didn’t fit with the new flywheel housing. I lost a little over 0.5 inches^2 of area going to the oval exhaust, but it did fit between the body and transmission without any additional massaging...
