This photo is 10 years old.	1986 F250 4X4. 6.9L (421) Diesel V8 Engine coupled with a Borg-Warner T18 4 Speed and Borg-Warner chain drive transfer case. 93K miles showing on odometer. Could be 193 or 293K who knows? The odometer only has 5 and 1 tenth digits. The rear axle is a Dana? semi floating axle. 3.54:1 Ratio The front is a Dana 50 10 bolt 8-1/2" gear independent swing arm style axle.
Camper off ( I hated it!). Trim removed.	This the most recent picture of my 4X4 F250. It is a lot more weather beaten since the photo above. It has spent the last 5 years holding my driveway down because the clutch had blew out the throw out bearing. This picture is after I finished installing to new clutch. I removed the bent up grill and headlight bezels. I have new units bought from LMC Truck. The clutch is from Dial-a-Clutch. I opted for the 12" upgraded clutch from the factory 10". This truck already had a 12" installed some time back. I also installed 2 new batteries, 1 new dual battery cable that goes to the starter and 2 new ground battery cables. In the past I had replaced the 8 glow plugs, Rebuilt the rear end with new axle seals, new brake cylinders.
With the old camper on and most of the trim.
The rear seal was in bad shape. It had been leaking for some time. This was of course the best time to repair this problem. I bought the Seal kit from LMC Truck. It came with a new 1 piece National Seal and a gasket to reseal the rear main plate. Ground clearance is great! I did all this work with the truck on its own foot print.	This is after replacing the seal. The crank shaft was worn where the seal was making contact. This is usually fixed with a speedy sleeve or machining the crank. I chose seating the seal about a 1/16 of an inch deeper to make the seal on a new clean area. Sealing between the plate and oil pan was done with Loc-tite brand blue RTV.
I had the flywheel surfaced by a local Fort Worth machine shop for 30$. They did it same day in just 2 hours! ED'S Automotive Machine Shop. 3322 N. Main St. Fort Worth, Texas 76106 (817) 624-2431 The pilot bearing was replaced using one of two that were supplied by Dial-A-Clutch. Mine used the smaller one of the two.	This is with the new clutch and pressure plate installed. I left the Alignment tool in place to keep dust and dirt out of the pilot till I installed the transmission. This clutch is a lot easier to push in than the old one.
After the clutch was done I turned my focus on the transmission. I rebuilt the Borg-Warner T18 4 Speed transmission as well. All bearings, seals and gaskets were replaced. There was no need in replacing the synchronizers, they were in very good shape. I painted it with Motor paint. GM Blue to be exact. GM on a Ford, kind of funny. I got a good deal on the paint, $1 a can instead of $4. The rebuild kit came from Standard Transmission & Gear Co.
