Handling & Care
Make sure to clean and lubricate any gears you install or swap. Unless you are very careful during handling and storage, the coating of grease on the gears will easily pickup dirt or debris, which can then spread to the other gears and increase the rate of wear.

Lubricating
1.DISCONNECT LATHE FROM POWER!
2.Remove the headstock side cover and all the end gears shown in Figure 121.
3.Clean the end gears thoroughly with mineral spirits to remove all the old grease. Use a small brush if necessary to clean between the teeth.
4.Clean the shafts from which the end gears were removed, and wipe up any old grease splatters in the vicinity and on the inside of the headstock cover.
5.With clean hands, apply a thin layer of grease on the gears. Make sure to get grease between the gear teeth, but not so much that it fills the voids between the teeth.
6.Install the end gears and mesh them together with an approximate backlash of 0.005". Once the gears are meshed together, apply a small dab of grease in the crux of where the gears mesh
Annual Maintenance
