My recently-acquired Accucraft Mich-Cal #2 Shay runs beautifully
, but has one problem
- the gas tank filler valve seems to require a LOT of physical pressure on it to get the tank to fill, & then does NOT "spit back" when full as the valves on my 3-Cylinder (Mich-Cal #5) Shay & Ruby #11 do, making it difficult to tell when the gas tank is actually full.
I'm using a filler tube acquired from Royce at Quisenberry Station to fill the tank (works with the Asian - style 8 ~ 10 oz. butane cans, works fine with my other 2 engines); the valve assembly has clear plastic tubing connecting the filler section to the can valve, so I can actually see the butane flowing. The ONLY way I've been able to tell if the gas tank is full is when I see bubbles quit moving from the gas can to #2's tank, or move in REVERSE. Although theoretically "used", this loco was shelf-displayed ONLY by the previous owner, NEVER ran until I got it.
How would I go about removing the valve to check it
- Noting the way the top of it is made, it looks like a spanner wrench of some sort would be needed for removal (I'm assuming it unscrews); or is it adjustable
I think I could probably grind a notch in an old screwdriver blade to make my own spanner wrench, but I'd like some input from anyone who's actually disassembled one of these valves before I try anything.
