I have a older Jet 13 X 40 belt driven lathe the leaks oil out the rear spi
ndle. The lathe has a tumbler feed select not the newer lever select.
Looking at the parts list I don?t see any seal s or O-rings. Two nuts
press against a clamp that has some oil flow groves machined into it. The
clamp clamps the shaft to the main roller bearing.
The lathe was rebuilt by a previous owner and it looks like he used Permate
x instead of new gaskets that hold on the bearing mounts. Oil is not leakin
g from these seals. The gaskets are not near the shaft.
I have some suspicions but I would like some unbiased suggestions.
