EX Rear Axle

The rear end as built was modified slightly from the original. I have included the drawing as was original, and as modified.
The axle ends were modified and built with five inch tapered keyed ends, and the drums were made to accept them. The bearing are deep grooved sealed ball bearings and are arranged so when the wheel is installed, tension and preload is applied to both the inner and outer bearing. No side thrust from the wheel is against the planetary gears. The gears used are original.
The inner brake band cleaves and bolt was modified per the drawing so as to facilitate the ease of adjustment. The outer brakes originated in 1907 and I modified them by bonding brake lining material to the bronze shoes. All castings are 85-55-06 ductile, the axle tube is 3/16 - 4130 and the axles are 4140. The front axle is the same except for the spindle castings; they are A-148 structural steel 110,000 Tensile and 90,000 Yield and have tapered rollers for bearings.

ASSEMBLY

Assembly of the front and rear end together with the perch rods is quite straightforward.
Caution needs to be taken to keep the rear end from bowing and also to keep the wheels square to each other.
The tie rods needed some forging to copy the original. The rods are 3/8-OD with 9/16 hex stock slipped over the rod and silver brazed in place. The ends of the rods are then forged in a die to a larger diameter to ½ inch to enable them to be threaded to 7/16-20.
The perch rods I used are hickory as I was lead to believe by others was as the original. Other builder of reproduction Stanley’s are using 4130 steel aircraft tubing.
The Yellow paint used was computer matched to old paint on original borrowed drums, it was wet sanded to remove dirt and oxidation. It matched up to John Deere Yellow TY25641. John Deere has six different shades of yellow paint. Other brands also had a match.
The wood wheels are original Model EX wheels and needed a lot of epoxy and finish work. New wheels are still available.
