SRM450 Pole Mount Insert Rework Instructions
Note: These instructions are to be used along with Mackie kit P/N 020-006-00 to
repair SRM450s which already have the pole mount insert stripped out. The
pole mount bolt assembly (bolt, knurled brass insert and alignment bushing)
must still be with the unit as the parts will be recycled and also used during the
rework.
1) Remove stripped out pole mount bolt assembly. This can be done by hand – one
or two sharp jerks on the bolt should pull the assembly free.
2) Unscrew the defective brass knurled insert from the bolt and remove the black
metal bolt bushing.
3) Screw the metric nut (M6x1.00) onto the insert installation tool until it stops.
4) Screw the new replacement threaded brass insert onto the end of the installation
tool until it stops against the nut.
5) Slide the black metal bushing down onto the insert tool so it is behind the nut
(shoulder on the bushing should be away from the nut) – this will be used to align
the new insert during installation.
