Fit the platter

Oil the bearing

Run 7 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.

Ensure the spindle tapered mating surface is absolutely 
clean before assembly. Place the platter on the spindle 
and finally add the platter mat.

Notes on bearing:

For lowest friction, the oil film has a significant depth of 
“float” so an almost imperceptible platter movement is 
inevitable. Small low frequency deviations of this nature 
are insignificant to performance.

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. It may help to rotate the 
platter slighty before refitting so that it's at a different 
orientation. 

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.

Adjust deck feet

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

Set the plinth height by rotating the 3 adjustable feet. It 
helps to lift the deck slightly for access to each foot in 
turn.

To set the plinth height correctly, place the motor pod 
just beside the platter as shown below.
