Stewart Warner Wrenches

[J.A.F.E.]

I didn't know they made wrenches either. One of the vendors at the swap asked me find out some info on these and so I send out an appeal. These look to me like aviation or transmission/driveline specialty wrenches but I don't know. They don't seem to be overly well finished and the plating is not very well bonded so aviation is not as likely in my mind. Part numbers are 3267414-1, 3267414-2, 3267414-3 and 3267414-4. Seems to be a set or part of one. Sizes are not marked on the wrenches the -1 and -2 are 3/4, -3 7/8 and -4 15/16.

If anyone is interested in them they do not belong to me but I'm sure Gordon (the vendor) would be happy to discuss it.

Any ideas?

Are those for distributers or aircraft cylinder nuts?  Just looking at 'em I'd guess, distributers.  But those large sizes got me stymied.... Maybe both???

JAFE,

The size of the wrench openings pretty much rule out automotive distributor wrenches.  Aircraft engine applications might make sense, but I'm no expert in this area.

The shapes, and the fact that 2 of them are extra deep boxes, and the fact that the back end is clear for a cheater bar leads me to guess they are crank bearing wrenches. The 90 gets you in between bearing pillars, and the double kicked one would get you over the bearing cap.

The opening sizes are rather large for that, but not impossible (say for a large diesel engine)

Only a wild guess tho. SW did make some pecular things for the govt.....
