I always will put the bar full corner in the direction being towed.
If it is not live steam. its not worth it.

that said, if the cocks can be opened with out getting sucked closed. it should not make a difference.

Make sure your axle pump is in 100% bypass... Been there, done that. Got the "OMG!" when the guy towing the engine back to the bay started seeing water spurt out of the safety valves. "Ope... Let's open that bypass!"

OK, but if the JB is in the center are both ends of the cylinder connected to the exhust port?

Re: Pulling a cold engine
No, all the ports should be covered if the Johnson bar is in the middle. Easiest way is like Cbrew said: Johnson bar in full gear in the direction it is being towed, axle pump off, brakes off, and cylinder cocks open if possible. Moving a dead steam engine presents a tremendous drag, so don't be surprised if it is still pretty hard to tow.

Rod engines can be tough, but try to move a Shay by hand! That will wear you out if there is any significant distance to cover!
I try to keep the reverser in the direction of travel, cyl. cocks open etc. makes it much easier.

Re: Pulling a cold engine
This post got me thinking........how do you keep the cylinders lubricated? Do you need to make any modifications to other lubrication points, or change what you are using as a lubricant?

I must have a problem, no matter where I place the reversing lever the engine rolls very freely..no drag.
I have auto cocks, are they breathing?
