Fairbanks Morse Model 45- rebuild

Oh....When Woodmanse bought Stover, they used lots of their ideas. As far as the wires are concerned, the setscrews were all drilled, and the original wires were still in them.

Okay, here are the pinions. SURPRISE! They are in with a pin! I was looking for keys not pins. I broke one, as you can see. The pins do not go all the way thru, but stop just short of coming out the other side of the gear.

6 ft 702, or probably 602 gears will work as replacements. Teeth are the same, hole is a touch smaller for the 702, thats ok. I will check the 602 pinions tomorrow. Hole should be the same for the shaft.

Bearings for the mainshaft, and crank gear shaft. Hyatt for mainshaft, like the book says. Babbitt for the crank gear shaft, but the book says bronze. Will either go back with brass, or babbitt for both.

This is the make-up of the oil pump.

Alright, finally getting to upload photos.

4-1/2” outside to outside on the guide rods

2” from the pin on the roller cross head to the centerline of the pump guiderod

3” from pin to pin on either side of the roller crosshead

4-1/2” out to out on the roller cross head.

Looking at the parts list, the 6’ and 8’ mills shared the same roller crosshead, crosshead roller, and Oiler lifter.

And a question for the class. As I am disassembling this mill, do I need to be careful to mark parts and put them back on the same side that the came off of? I.e. does the left pinion gear need to go back on the left, or are they interchangeable? I’m concerned that parts are “worn in” in its current position and needs to stay there. Am I overthinking this?

Interesting. Mine were designed with woodruff keys

I double checked mine and they were not drilled for wires. I’ll be putting them back with holes drilled. I like that.

And last post of the night- some nice Stover literature I found online. Some differences, but plenty of similarities.
