3.5.4 Excess Gearbox Noise
Gearbox noise is louder than normal. Take note of the gear where the noise is most noticeable.
Remove the gearbox lid and try to isolate where the noise is coming from.
Possible Cause
Check This
Headstock manual oil pump failure
Make sure oil is flowing in the site glass. The oil
pump is run off a gear in the headstock.
Shift level out of position. Gears are not
mating properly.
Move the shift lever in and out. Turn off spindle and
put back in gear. Adjust the gear cluster in question
to make sure it is mating properly.
Lack of lubrication to gear train
Check level of oil in gearbox
Spindle bearing not being lubricated
properly, worn bearing
Check to make sure oil is finding its way to the
bearings.
Spindle preload loose
Tighten spindle preload on bearing. The spindle
preload should be approximately 10-15 in/lbs.
3.5.5 Headstock is Leaking Oil
A Form-A-Gasket sealant should be use to seal any leaking areas. Make sure the sealant fills the
leaking area thoroughly. Sealant must cure for 24 hours for best results.
3.5.5.1
Leaking Oil from Rear of Gearbox
Possible Cause
Check This
Leaking from behind belt drive pulley
Replace shaft seal - o-rings or gaskets.
Oil leaking from behind the spindle
encoder.
Remove spindle encoder and check seal.
Oil leaking from the rear bearing
assembly.
Make sure the rear backing plate is mounted correctly.
There should be a tapped hole located at the 12
o’clock position. If the tapped hole is located at the 6
o’clock position the seal will leak.
3.5.5.2
Leaking Oil From Front of Gearbox
Possible Cause
Check This
Oil leaking from seal between lid and
gearbox
Remove gearbox lid and reseal. Thoroughly clean lid
before resealing. Make sure the front backing plate
matches up with the seal behind the cover.
3.5.6 Tailstock Barrel is Stiff
The tailstock barrel is stiff or not smooth moving through its travel. The tailstock barrel
subassembly jams inside the tailstock
Possible Cause
Check This
Misalignment of tailstock housing
Realign bearing housing and tailstock screw. Loosen
screw support and realign.
Too much grease.
Disassemble and remove excess grease. Add oil to the
tailstock barrel.
Vernier Dial is binding or rubbing on
screw support.
Remove dial and machine off a couple of thousandths
or shim.
