Assembly of deck sub-chassis to Aurora plinth
Read carefully or damage can occur
Please fit the Subchassis (single or dual armboard) to the plinth following the instructions
on these sheets. This part is not pre-assembled to prevent potential distortion that can
occur in transit if it is rigidly attached to the plinth.
Preliminary notes Do not tamper with any of the bolts on the sub-chassis even if they
may not appear to be seriously tight. In the case of the dual armboards the armboards have
been levelled using bolt tensions.

The deck arrives as shown above. First, undo the
Pivot nut using the spanner provided whilst holding
the bolt head on top with the Allen key. It is easiest to
rest the deck on it's side (see photo alongside) whilst
you carry out this operation.
Once the nut is removed, Make a mental note of the
parts and their positions before withdrawing the bolt.

FITTING THE SUB-CHASSIS
Fit the bolt through the hole in the top of the sub-chassis
and re-assemble parts as they were before only now the
sub-chassis sits on top of the whole assembly. position
and and then place the sub-chassis over it such that the
ant-rotate stud locates in the plinth hole made for it. Now
manoeuvre the sub-chassis to the position where the
pivot bolt can drop down through the pivot spacer – the
damping disc – the plinth – the underside damping disc
and then thread on the underside nut.
The pivot bolt nut needs to be tightened firmly so use an
allen key on the bolt and a spanner on the nut. If you only
have a pair of pliers this is best carried out using an Allen
key applied to the bolt head. Ensure the anti-rotate stud
stays located in the plinth while you tighten the nut and
once tightened ensure that it is still located in the hole.
This is CRITICAL or the sub-chassis will not be level and
performance will be severely affected. If all is finished
correctly then the sub-chassis should be free to rotate
almost imperceptibly in the horizontal plane as the antirotate stud is a loose fit in the plinth hole.

If you need to send the deck by carrier then remove the
sub-chassis and pack the plinth and platter according to
packing instructions – remember to tighten the pivot
spacer onto the plinth using the pivot nut.
You are now ready to move on to the owner manual for
final set up.
