S7 power cross feed oiling issue?

After a smal misshap with th power crossfeed clutch (now fixed, loose bolts), Ix investigated the apron a bit closer. The bevel gear that takes drive from the leadscrew keyway does not seem to get any oil at all at its bushing. The driling from the nipple just to the left of the oil reservoir level plug that leads in the direction of the gear is not drilled through the bushing. Is this correct? The lathe. In question is a early S7 plus with the oddball bullwheel (67t). Perhaps not everything was perfect, after all. Should I try to drill the oilway through? Or is the bushing permeable to oil?

Regards

Good Morning Bjorn,

I would concur with Gray, I have a S7 long bed bought new c1976 with power cross feed, recently I had to strip down the apron for servicing of the half nut [operation became stiff ] Even though my machine has been in daily use for all these year there was no appreciable wear on any of the components/bushes etc in the apron. I would not worry at all -- as Gray says lubricate and forget it for many years.

Incidentally I used to use a "sticky" oil Shell Toner R41 for the gears and lead screw - now run out of this and its no longer available so now use chain saw chain oil which is "sticky" and tends not to run off the gears and lead screw.

John
