Title: 2 truck Shay
Post by: Gayhalo365 on March 03, 2026, 02:37:33 PM
Can anyone tell me the type and size of screwdriver needed to undo the screws that hold the universal joints between stream engine and the trucks together.
Could my engine be so old that the two parts were riveted. I can see a brass end about 2.5 mm with a 1 mm hole in the middle. I have sourced a big set of small screwdriver bits none lock into the hole.

very small! don't know the actual size...

with Chinese manufacture goods, you need a plethora of philips/cross drivers and use the one that fits best.

I have a couple of sets that have about 6 different bits in various profiles and sizes.

word to the wise: don't lose them!!!
