HOW TO SERVICE NOVA CHUCKS


SAFETY WARNING
Safety glasses must be worn when dealing with snap rings on the
chucks. Snap rings can for fly off in any direction. Use caution and
wear safety glasses.
 Note: Remove jaws or any other accessories attached on the chucks
before disassembling the chucks. Wipe/blow off visible dust from the
chucks before disassembly.
Preparation:
Before starting the disassembly, lay a disposable thick towel or cloth on top of the
working area as the disassembly process can get messy. The towel will protect the
chuck body during this process.
This guide outlines the disassembly, cleaning and reassembly for:
 Precision Midi
 G3
 SuperNOVA2
 Titan

3.
Remove the threaded pins (that are
holding the pinion gears in place) with
a 3mm Allen key.
There will be two of these pins in total
- one for each pinion gear.
Remove pinion gears by pushing out
of the chuck body.
4.
There will be another retaining circlip
holding the scroll ring in position.
Using the external circlip pliers,
remove this circlip.
5.
Remove the scroll ring out from the
chuck body. This should slide out but
if it’s stuck in the chuck body, you may
need to use a bit of force to the chuck.

6.
On two of the slideways there will be
a stop screw which prevents the jaw
slides from disengaging with the
scroll ring during use. Remove these
stop screws using a small flat head
screw driver.
Then the jaw slides will be free to
slide out of the chuck body.

Titan – Cleaning
STEPS DESCRIPTION IMAGE
1.
Use a disposable cloth/ towel to wipe
off much of the visible dirt as possible
on each part.
2.
To remove built up grime, apply a
degreaser/rust remover (e.g. WD40)
on each part. Leave on for at least two
hours (or as directed on product
instructions).
3.
Use a wired brush to remove the rust
and grime.
4.
Use a clean disposable cloth/ towel to
wipe the part after brushing.
The parts should feel dry and
shouldn’t leave any sticky residue on
your fingers.

Titan – Reassembly
STEPS DESCRIPTION IMAGE
1.
Before reassembly, apply a generous
amount of lubricant where parts come
into contact.
We recommend applying the lubricant
to the inner surface of the chuck body
as well as the jaw slide slots before
assembly. Also, apply lubricant on the
spiral teeth side of the scroll ring.
2.
Reinsert the jaw slides back into their
original slots.
Looking from the front, the jaw slide
number should be counting up from 1-
4 in the clockwise direction.
3.
Flip the chuck on its face and position
the jaw slides to form a square in the
centre as shown.
4.
Slide the scroll ring back into the
chuck body. Once it is in place, rotate
the scroll ring until it engages with the
jaw slides.
You should be able to feel the scroll
rings engage as it will drop into place,
exposing the slot where the snap ring
will fit.
Alternatively, you will see the jaw
slides move as you turn the scroll ring.

chuck body and insert the threaded
pin back in to hold its position.

Rotate the scroll ring with the chuck
key to check whether the jaw slides
correctly match up at the centre.
If the jaw slides match up correctly at
the centre, screw the position pins
back on.

Install the backing plate onto the
chuck and put the retaining circlip
back on to finish.
