Working at fitting up the spindle (new bearings) on my 63' Modular drive. The head stock is the earlier style having three sight glasses.
I have no operating history with this machine so there are some questions
I am under the impression that these 3 glass head stocks can have issues with the oil draining out of the spindle bearing cavities.
I see that Monarch changed the slinger style when they went to the single sight glass head stock.
Of the changes, one includes an o-ring to seal the OD of the forward spindle slinger....Plus a different design on the slinger internal geometry itself.
Thinking that going with the later design might help reduce the oil migration from the spindle bearing cavities.
I have an original "late" spindle side slinger (thanks Dave) and i have reverse engineered the matching outside ring ...I realize that there are some differences with the oil drillings.
Looks like it would be possible to add the drain back and retaining screw drilling/tapping.....
Anyone here have any thoughts about doing this....Am i swinging at windmills, or is there any value in going this route....
Cheers Ross
