Front Axle Ring Spanner

Description

This tool is used to remove the castellated ring nut from the rear of the front wheel hub.  It is based on the one shown on page S-7 of the Y type Maintenance Manual.  However, it does not include the base plate, so a way of holding down the hub while using this tool will be needed.  The suggested tommy bar is not included either, so a locally sourced bar at just below the 5/8″ diameter recommended will be needed, about 10″ long.

The aluminium ‘plug’ locates in the wheel bearing and acts as a guide for the castellated ring spanner.  This is also different from the original tubular insert that used the oil seal location as a guide. 

If your current castellated ring nut has been severely damaged by previously having been tightened with a hammer and drift, you will need to carefully remove all ‘peened over’ surplus material from the damaged sections to allow the ring to move at all.  IMPORTANT – the left hand side hub has a left handed thread and the right hand side hub has a right hand thread (See page M23 of the manual).
