Change Gears

Grease Type	............................................... NLGI#2
Frequency	Annually or When Swapping

The change gears, shown in Figure 130, should always have a thin coat of heavy grease to minimize corrosion, noise, and wear. Care must be taken to avoid over-greasing because excess grease will be flung onto the V-belts, which will cause the belts to slip and the lathe to lose power.

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.

Make sure the cover remains installed whenever possible to keep the gears free of dust or debris from the outside environment.

Lubricating

1.DISCONNECT LATHE FROM POWER!

2.Remove the end gear cover.

3.Clean the change 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 together—this grease will spread around when the gears start moving and re-coat any areas scraped off during installation.

Annual Maintenance

Once a year, remove all the change gears, clean them thoroughly, and apply a new coating of grease. Even if the end gear cover has been kept in place throughout the year, it is still possible for dust from the V-belts to build-up in the grease, and the grease may also start to break down with extended or heavy use.
