NESCo volunteer Bob DeWachter has been hard at work on the restoration of 470’s stoker motor, and shared these photos this morning from his shop!
“I finally got the pistons separated from their rods. Had to use a friend’s large hydraulic press to pop them free from the tapers. The square block is a jig I had to make to properly support the back side of the piston body. Some parts have been prepped for powder coating. A lot of cleaning, wire brushing, and grit blasting to make them sanitary!”
“Prepping and powder coating the upper block cover. High temp mylar tape and foil used to mask off interior and gasket surface of the cover.”
“This is the only original tool we have that saw service with 470. It is a spanner wrench used to adjust the packings on the stoker engine. Bright red so we don't misplace it! Held in place on the block by one of the packing locks. Upper block cover after unmasking. Upper cover set in place on the block.”
