The leadscrew is secured to a connecting collar

that is part of the headstock drivetrain with

the use of a soft-metal shear pin. The shear pin

is designed to break and disengage the power

transfer to the leadscrew to help protect more

expensive lathe components in the case of a

carriage crash or the lathe is overloaded.

Contact South Bend to order a replacement shear

pin (Part Number PSB10160927) or use the

specifications in Figure 127 to fabricate your

own.

Put on safety glasses.

Shear Pin

Head

Shroud

Washer

Rotate the shroud washer on the leadscrew

(see Figure 129) so that the cutout lines up

with the shear pin head.

If you fabricate your own shear pin, make sure

to use the material and dimensions specified

Figure 127. Otherwise, the shear pin may

not provide the intended protection and lathe

damage could result.

To replace the shear pin:

DISCONNECT LATHE FROM POWER!

Clean debris and grime from the shear pin

area (see Figure 128).
