Need help identifying my horizontal engine
« on: November 26, 2019, 03:44:23 pm »
Hello All,
 I need help identifying my horizontal engine. I believe it to be an early (pre 30's) Stuart 10H.  Most parts are ferrous metals except for the main journal caps, the 1st half of the connecting rod off of the crank journal, the valving rod and packing gland flanges which are possibly Aluminum? The piston is brass with a leather sealing ring. Has 3/4" bore - 3/4" stroke. The last picture is from a 1926 Stuart catalog.
Thanks, Algon

Made a correction to the text in my post regarding materials. Was Aluminum used that long ago? Just not sure. Also has slotted screws I see many earlier Stuarts used hex bolts. Possibly been reworked with new hardware sometime in it's life. I'd like to replace them with bolts. Need to do some thread checking. Were earlier ones fitted with Whitworth (BSW) or metric hardware?

I think aluminum was used pretty far back, though I don't have a date. I doubt that slotted screws were ever used by Stuart. As for fasteners, check to see if they are BA threads; Stuart used those a lot.

It is quite unlikely that any of the original Stuart parts were aluminum.
The builder may have buggered up the original parts and made aluminum replacements.
