1992 W250 Resurrection/Modding
Today I changed the oil and filter. 3 gallons of Premium Blue 15-40w and Fleetguard 3349 filter. I also changed the fuel filter, eliminated the fuel pre-heater and WIF sensor. I put a Baldwin BF9893 on it. I also built a battery hold down bracket for it. The factory one rotted off and the parts store brackets were cheap chintzy plastic things. Pics to follow.
Today (in the wee hours of the morning) I pulled the cover off my Dana 70 and drained the chocolate milk colored "gear oil". I wanted to see what gear ratio it was and check the general condition of the diff. 3.54's lots sludge on the magnet. I pulled the vent and drilled the crud out of it (it was completely plugged).
Half of the carrier had flaky rust on it as did the inside of the diff cover so I took the wire cup wheel to it to clean it up. Then I sprayed brakekleen all over it to clean the dust/rust off it. I scooped a couple handfuls of rusty sludge out of the bottom of the case, cleaned it up with some rags, and put a neodymium magnet out of a hard drive in the bottom of the case to catch remaining metal/rust. The magnet on on the diff cover had a bunch of sludge on it.
The ring gear looked good. No abnormal wear or rust on the ring gear. Backlash seems good (checked with by-guess-and-by-gosh method). Bearings seem tight and smooth.
I filled it up with Kendall 85-140w, put it all back together and drove it up and down the road at 0330hrs. Yay.
Can't wait to see what the front axle looks like...

I needed a battery hold down bracket because the stock one rotted off. I went to the usual parts stores and found a lot of chintzy plastic crap so I decided to make my own. I used two 4" pieces of bed frame and 8.5" of 3/4"w X 1/8" steel strap. I drilled a 5/16" hole in each end of the strap centered 1/2" from the end. I rounded off the edges of the strap and welded the pieces of bed frame to it 7.5" inside to inside. Then I painted it YELLOW!!!
Way better than the aforementioned junk!

No prob! I've used bed frames to build all sorts of stands, brackets, etc. I usually get frustrated when all I can find is junk plastic "universal" stuff and end up making my own. I also do a lot of my work at night after the parts store is closed so I kind of have to build my own stuff. Besides, I enjoy making my own!
Today I removed the old, bubbled, violet colored, poorly applied tint film. It took about an hour with a razor scraper. The adhesive was so old that I wiped it right off with Windex and paper towels. I read about steaming it off or using 3M adhesive remover but decided to do it the old fashioned way. It was 38 degrees and I was concerned that a steamer might get too hot and crack the window.
