Could be a replacement torque tube? I can't say I've seen or heard of anything like that before. Got a picture?

All is not lost. Just remember the "finger in the #1 Cyl" will work all the time. Always worked for me.
Good Luck!

Those two flat head screws are probably the impressions from the flat screws that held a cover plate over the hold on the original casting pattern. I don't think they will turn. Maybe it was an option for a military version headed for jungle service and they didn't want excess holes to get outside stuff (like mud and rain) on the clutch.

The way I time mine is with a wire to feel the piston position through the spark plug hole. I just use the inspection hole to double check when it is getting close. Dave.

Does it have the big hole on the bottom?
That is definately a mod to the wood pattern in order to remove that hole.

I have an Allis B that finally after almost 50 years of faithful service, refused to start. I have no spark so, found the specs and started checking out the mag, but can't find the hole on the side of the torque tube to set the timing. There is a 3" angle iron frame bolted and welded snowplow over the side of the flywheel housing so it could be behind that, but I hate to remove the whole thing to find it. I noticed this post but the photos of the location don't load.
Can anyone give me the exact location of the hole or repost the photo.
Thanks,
Smiley

It sounds like the 3" angle is bolted over the inspection hole in the torque tube (clutch housing), If you do as other member's posted, thumb in the spark plug hole, or wire in the spark plug hole to feel when piston is at he top of it travel, (after you feel air escape with your thumb, to be sure that you are on the compression stroke). You need to feel the air coming out of the plug hole or you could be 180 degrees off on your timing. Bob

  the 1st picture is the one without the hole & the 2nd pic is one with the hole , hope that helps you . your hole is probably under the angle iron.

1946WP and Chalmers Bob,
Thanks for reposting those photos. That answers my question and that's where I thought it should be from the descriptions. The hole is under the angle irons if it exists. I'll try to check it today. I could have timed it the other way but I would just as soon have the mark to be absolutely sure of tdc. We used to have a motorcycle business and that's how we timed them, with a degree wheel and small sliding rod in an old spark plug body that indicated the piston at the top. The thing that I noticed about it was there was always a slight amount of slack as it rolled over the top, that could throw you off a couple degrees.
Unless I get more time and good weather, it may set until spring as I covered it up outside yesterday. I adapted a Wheel Horse loader and forks to it and use it for moving pallets of firewood and stuff around. My firewood is already in and don't and don't really have much need for it during the winter. I had adapted a Cub Lo Boy front mounted blower to it and on my first trial run found out the hard way, that Cub PTO's run backward of everybody else's. Best little snow sucker you ever saw.
Thanks again,
Smiley

Smiley, My favorate is not that sophisticated a tractor. The finger in the hole always worked for us. As I said many times I did not know the B had timing markd - hard to believe we never looked on the flywheels we had when we overhauled them - till I got on this site. Finger in the hole will get it running then you can move the mag with the ear bolts loose till it sounds right. Worked fine for us.
Take good care of my favorate.
Good Luck!
Bill Long

I checked it today and by poking a bent wire behind the angle iron, found the hole. I'm sure that when I get at it, I'll use the finger in the hole and wire method because the plow/loader frame is totally welded, except for where it's bolted on the bell housing and in front.
Thanks again,
Smiley
