13. repeat Steps 3–7 on the outboard spindle
bearing.
14. reinstall the spanner nut. only tighten the
spanner nut far enough to achieve 0.001"–
0.002" end play on the faceplate.
Tip:
Use a dial indicator, as shown in
Figure
68 on Page 45, to measure end play on the
faceplate.

General Lubrication
an essential part of lubrication maintenance
is cleaning the components before lubricating
them.
this step is critical because dust and chips build
up on lubricated components, which makes them
hard to move. simply adding more grease to built-
up grime will not result in smooth moving parts.
Clean the components in this section with mineral
spirits and relubricate them.
the following are the main components that need
to be lubricated:
•
tailstock
•
inboard toolrest
•
outboard toolrest
•
spur and Live Centers
Tailstock
1. Loosen the tailstock lock lever, slide the
tailstock off the bed, then turn it over.
2. Clean the shaft on the underside of the
tailstock with mineral spirits and a rag.
3. place a couple drops of light machine oil at
each of the locations shown in
figure 52.
4. pivot the tailstock lock lever and move the
locking plate back and forth to distribute the
oil.
