Fit the 

 

 Spindle

 

 

Oil the bearing

Run approximately 17 drops of the oil supplied into the 
top of the bearing house. The spindle will appear a loose 
fit in the bearing house until the oil is added. Do not use 
anything other than Origin Live oil for performance 
reasons.

Insert the spindle

Inserting the spindle into the bearing house needs 
attention as careless handling can damage the bearing 
surfaces. Wipe the spindle surface first to ensure that it's 
absolutely clean and very gently insert it into the bearing
house. If the oil does not overflow when the spindle 
touches the bottom then try 2 more drops repeatedly till 
you achieve overflow. Overflow can only be seen by 
looking at the top of the bearing house with the spindle 
inserted. You should notice an oil ridge around the 
spindle – see diagram below.

Wipe away excessive overflow at the top of the bearing 
house but be careful to leave oil clinging to the spindle 
as you need the top of the bearing to be lubricated by oil 
overflow and things like tissue paper can suck this area 
dry by capillary action. You should spin the spindle 
slowly after it has settled into the bearing to ensure even 
distribution of oil.

Note that when you oil the bearing, you can get a false 
impression of overflow if the spindle has oil on it - the 
oil simply scrapes off as the bearing slides in and ends 
up on the top of the bearing house. You can “feel” 
overflow when you insert the spindle and it meets 
resistance at the bottom. This is not a “thud” of the 
spindle hitting the bottom but rather a build up of 
pressure as the bearing lands on a bed of oil. By further 
pressing, you can then see the oil being squeezed out at 
the top.

Notes on the bearing:

The bearing has significant play “rock” which runs 
counter to expectations. However, this feature achieves 
very low friction levels. The spindle effectively rotates 
on a thick film of oil without contacting the bearing 
sides.

This means there is almost imperceptible platter 

movement in rotation. Small low frequency deviations of
this nature are insignificant to performance and far 
outweighed by the advantages of low friction and 
reduced vibration.

All platters are rigorously checked for level spinning up 
to 45rpm - if you notice significant platter flutter once 
the belt is fitted, then remove the platter and clean taper 
surfaces. Refit it till it sits true.

Do not spin the platter faster than 45rpm as the bearing 
relies on a high precision oil film designed for optimal 
sound quality within a specific speed range. At higher 
than normal running speeds there will be slight platter 
flutter.

Fit the Platter

Fit the platter gently over to the spindle but ensure the 
tapered mating surfaces are absolutely clean before 
assembly by wiping with tissue paper.

For Multi-Layer platter if included

Holding the Multi-layer platter

The top thin layers of the multi-layer platter are fragile 
so do not hold the weight of the platter using the top 
layers – also avoid placing the platter upside down on 
surfaces as the spindle is fastened to a relatively fragile 
material.

Slacken screws in the Multilayer 

P

latter by 2/3rds 

of a turn

The screws are tightened for transit to keep all layers 
concentric with one another. However once you have 
mounted the multi-layer platter, slacken all the white 
nylon screws in the top of the platter anti-clockwise by 
2/3 rds of a turn. This step is 

essential

 to allow the multi-

layer platter to perform as intended and makes a big 
difference.  

Fit Platter Mat

Finally add the platter mat ensuring the printed logo is 
uppermost for sound quality reasons.

Adjust deck feet

No foot should be tightened fully onto the plinth as 
performance is best when the foot sits on the thread 
alone.
