After three - four years of
production and millions (our estimate) of yards of yarn wound into
balls, we have learned that yarn fibers will tend to go into places that
no one originally imagined. Because of this fact, plus other normal wear
factors, we have developed a
maintenance procedure for users of our ball winders that should be
performed on a periodic basis as follows:
Maintenance
Schedule
- Yarns Shops and
other Heavy Duty users*
- Every 2 years
-
- Medium Duty Users
(which fall in between Heavy and Light Duty users)
- Every 3 - 4 years
-
- Knitters at home
and other Light Duty users
- Every 5 years
_________________________________________
*Heavy Duty users wind
10 or more balls per day every day, 50 weeks per year (2,500+ per year)
Medium duty users wind 25+ balls
per week
- Light Duty users
wind 10 - 15 balls per week (500 or
- less balls per
year)
Spindle O-ring - The rubber O-ring
that surrounds the Spindle Flange should be replaced every few years. If
a visual inspection of the o-ring shows that it is cracked, then
it should be replaced. Cracking mean that it has become less complaint
and it will not flex as much as it should as the conical shaped shaft
presses against it. So, we recommend that every 3 years, the user should
replace the o-ring. Users in drier environments such as the Southwestern
USA may want to change it more often.
- Maintenance Areas:
- Clean fiber from gears
- Lubricate metal and plastic surfaces***
- Replace Oring around spindle flange
- Adjustment Areas:
- Oring Adjustment
- Collar adjustment
*** Update 2010
- we have noticed that different lubricants that we have applied (and that
others have applied during maintenance) have actually caused some issues.
Specifically, some of the lubricants have become STICKY and GUMMY and have
caused the unit to slow down.
Therefore, we NOW
recommend that the unit be thoroughly cleaned of any lubricant (the gear
teeth and all metal shafts that gears and other assemblies rotate around
such as the torque tube shaft). We recommend cleaning these areas with
RUBBING ALCOHOL as a mild solvent. In the process you will also be cleaning
the built up fiber debris from the crevices of the gears.
The one exception to lubricating surfaces applies to
the Torque shaft (this is the rigid shaft that points straight up from the
inside of the unit - the conical shaped shaft that the o-ring sits against).
The torque tube can squeak when turning around this shaft sometimes, so a
light lubricant applied to the metal shaft can prevent that. Use a std
lightweight machine oil (3 in 1 type) for this purpose only.
No other areas should be lubricated.
We no longer apply lubricant to the inner surfaces
of the unit during assembly. Although initially we believed that the unit
ran faster and more easily with lubricants applied (which it did), the long
term effects of gummy surfaces outweighed these short term benefits so we
now believe that no lubricants on the gears or the shafts that they rotate
around should be applied.
General maintenance - In addition to fiber accumulating inside
the unit, dryness of the air will, over time, wear any lubricant away that
coated metal parts and plastic gear surfaces. So performing periodic
maintenance will make the unit run smoother and longer without any issues.
Lubrication - only the metal torque tube and shaft a can be
sparingly lubricated with a standard machine oil. Do not put lubricant anywhere
else.
Over time, the plastic gears will wear in slightly. They are made
from a nylon compound and are every tough. They will never wear out nor
should any wear affect their performance. As they wear in, they should
actually run smoother.
The bearings that the shafts ride within are plastic and are made
by a leading European bearing manufacturer. They actually ooze dry lubricant out
onto the shafts as they wear. This is why they do not need additional
lubricant.
Adjustment Areas
The o-ring position and tightness against the conical shaped
shaft can change because the constant pulling of yarn off of the shaft can
eventually cause the o-ring to change its position. Normally, however, the
reason that it changes its position is because it may not have been installed
correctly by the user in the first place. No big deal, though, it takes less
than a minute to adjust it. Refer to this
procedure to adjust the o-ring or watch the
video.
This adjustment procedure and video also cover the collar
adjustment.
Maintenance Details
What exactly needs to
be done?
Although our ball
winder is an enclosed mechanism, there are some openings that allow yarn
fiber to penetrate. These fibers get inside the unit and find their way
between the heavy duty gear teeth. Part of this is due to the static
electricity that the fast spinning plastic gear creates combined with
the grease that coats the gears. The gears themselves also force these
fibers into the gear teeth crevices.
Over time, these
fibers build up and start to fill in the gear teeth
crevices until such time that there is no more room for the gear teeth
to fit into. The result? A tightening of the gear assembly.
What needs to be done?
The user must take the
Ball Winder apart and clean these gear teeth out.
This procedure will
illustrate how this should be done.
What tools do you
need?
- #2 Philips head
screwdriver
- 1/8" Allen wrench
- A straight #2 (flat
blade) screwdriver
- Optional: 5/16" nut
driver and 1/4" nut driver
- Paper towels
- Rubbing (isopropyl)
alcohol from drug store.
- Small pointed
(sharp) tool like an awl or a small screwdriver
How much time will
it take?
- Experienced,
unafraid person - 30 minutes
- Inexperienced or
cautious person - 40-60 minutes
Much of the time depends
on the level of debris that must be removed from the gears

Procedure to disassemble/maintenance the
ball winder |
| Remove the handle with the Allen wrench and flip the unit
over (on motorized units, remove the pulley). |
 |
| Use 1/4" nut driver or straight screwdriver to remove the 4
hex head screws holding the base on. |
 |
| Gently pull the base away from the main body and place to
the side. Wiggle base to free it from main body. |
 |
| Remove the Yarn Guide Post Arm by turning it back and forth
as you pull it off of the shaft. It is a tight fit but it will
come off (notice which side is which for later re-assembly). |
 |
| Free the arm from the shaft and place to the side. |
 |
| Look at the inside of the main body. Multiple gears and
shafts are visible. You will return here shortly. |
 |
| Use your 5/16" nut driver or straight screwdriver to loosen
the 2 s hex head screws holding the clamp ring under the spindle
arm. |
 |
| Lift the spindle arm and spindle off of the unit. |
 |
| Loosen the set screw in the shaft collar and remove the
collar from the shaft. Note: do not lose the white washer, this
must be re-installed with collar later. |
 |
| Pull the torque tube up and off of the torque tube shaft.
There is a small spur gear on the bottom. This may be greasy, place
it on a paper towel. |
 |
| Examine the gear teeth. Clean them with rubbing alcohol. Use
your sharp tool to clear any debris including old grease from
the gear teeth grooves. When re-assembling this, apply a light coat of
oil to the shaft UNDERNEATH the torque tube but not yet. |
 |
| Look in the hole where the torque tube came out of. This is
where the fiber gets into the unit. You will clean this later. |
 |
| Flip unit over and remove the 3 Philips head screws. |
 |
| The main body will start to separate. You need to gently
pull it apart. Keep in mind that gear teeth are meshed inside so
do not turn the halves and force them apart. PULL them straight apart
instead. |
 |
| Once apart, you can see the inside guts of the ball winder.
|
 |
| The main spur gear (2-1/2" diameter) is normally the gear
that has the fiber and grease trapped in its grooves. This
cluster gear can be pulled off of its shaft. Be careful not to
lose any white washers that are underneath this gear. These
washers MUST go back where they were when re-assembling the
unit. |
 |
| Examine the grooves of the gears and clean them out by
poking your sharp tool in the grooves. |
 |
| You will have to pick out the gunk and fiber with the tool.
No need to lube these surfaces. Use rubbing alcohol to
clean all gear surfaces during cleaning phase. |
 |
| Remove any excess grease from wood surfaces. This should not
be on newer units made from Qtr 2010 onward. |
 |
| In the bottom half of the main body, there is a small bevel
gear on the main crankshaft. Check this for debris and clean it
as best that you can (it cannot be removed). |
 |
Turn the shaft with your fingers while the 2 halves are
apart. Make sure it turns freely. The crankshaft rides on 2
special bearings inside the wood. Notice their position.
They should not be coming out of the wood. If they are, press
them back inside and test the shaft again. If the shaft does not
turn freely at this point, contact us.
|
 |
| Reassemble the unit
(refer to earlier photos) Put the large gear back on the short
shaft in the upper half of the main body (make sure the washers
are underneath the large gear).
Push the 2 halves of the main body back together.
Insert the 3 Philips head screws and tighten them. The hales of
the main body should fit together tightly with no gap between
them.
Re-attach the Yarn Guide Post arm. Be sure that the large
hole/slot in the end is facing up toward the main body (this is where
the 8" tall post goes into). Push the arm all the way onto this
shaft.
Attach the base (position the shaft into the hole in the top
of the base while observing the position of the 4 mounting
holes). Be sure these are lined up and then insert the 4 hex
head screws. Tighten screws.
Torque tube - Apply a light coat of
oil to the shaft UNDERNEATH the torque tube.
Insert the torque tube assembly. There probably was a washer
underneath it as well on top of the tube. Make sure these are in
position.
When mounting the collar on the torque tube shaft, leave a
small (1/32") gap between the collar and the tube assembly. The
tube must be able to rotate freely.
Check the crankshaft for ease and smoothness of turning. If
it does not turn easily, you may have to go back inside the unit
to investigate the cause. Otherwise, you are finished.
If you still have difficulty turning the crankshaft please
contact us. |
