Swapped out the 3.0 to 1 ruckstell for a 3.63 the other day. While it was out I slid the ball cap out to wipe clean and inspect, put it back in, installed rear end, everything went swell. Then was re reading the Model T service manual and it said to be sure and put the oil hole to the top (on the ball cap). I didn't remember seeing an oil hole so tonite I remove floor boards, hogs head cover, etc and looked inside and could not see a hole, so I undid the bolts and rotated the ball cap all 4 positions at least 4 times. It does not have a hole. Did the 27's not have an oil hole? If they did, how important is it? I assume it is to supply oil to the babbit surface. Is there enough splash to lube it anyway?
Thanks in advance.

Pulled the rear end, removed the ball cap. DOES have a hole, farther to the rear than the sample I had, and yes it was in wrong, hole was to the side. Only took an hour and 20 minutes to R&R so it is back on the road again.
