After about 5 years of inactivity, I am trying to put my engine for my 1919 FB Baby Grand back together. I am stuck right off the bat trying to remember what is between the back end of the cam and the rear motor mount and cover. Does anyone have recent experience with this issue? There is a brass thrust bearing on the front plate

A little confused about your question. The thrust bearing is placed on the cam first, then the cam gear is driven on until almost no clearance. The cam is then placed into the cam bearings ((a series of holes in the block) and then the thrust bearing is secured by two screws inserted through the holes in the cam gear and through the thrust bearing. Is this close to the answer to your question.

Thanks for your reply! I will have to look at that tomorrow! The brass thrust washer is currently screwed to the front plate of the motor which is also the motor mount (a wing type thing). On the back end, there is about 3/4 of a inch from the end of the cam to the back edge of the motor. A guy at my car club told me tonight that he thought that hole just got plugged??? More to come! Thanks again!

Yes, there is a hole in the back of the block which was used for the boring tool. That hole gets plugged with a "freeze plug" when the engine is being assembled.

O.K., I see what you mean. I guess the cam gear secures the position of the cam. Next question would be regarding the three equally spaced holes in the block next to the cam. They look like expansion plug holes, but I am sure they are not since there is no water going through that area. Maybe these are "wicks"? The guy that did the block and babbitting took them out. Not sure if he is even still in business!

Just as the cam has a hole in the block at the end of the cam, these are the access holes for the lubrication of each cam bearing. These holes are plugged to contain the oil and water does not get anywhere near them. The cam is held in place by the bushing held in place by the two screws accessed through the two holes in the cam gear.
