A search of you tube will reveal various methods of replacing the PDS and swingarm bearings. The Fungi racing tool has several advantages over other methods and tools:
-The safest way to avoid damage is to use the draw bar method. To ensure durabilty the Fungi Racing tool uses a grade 10.9 drawbar and deep drive nut. Combined with a three part thrust bearing, this enables a large force to be safely applied when extracting and installing bearings
-The CNC machined components fit perfectly and eliminate the risk of slipping out of position and causing damage to the bearing housing which is the likely to occur when using a hammer and sockets to replace bearings.
-The swingarm bearing install drivers have a unique machined 0.5 mm recess. This means the Fungi Racing tool is the only one that can install the new bearing to the exact correct depth as originally installed in the factory. No other tool can do this. All other tools and methods of swingarm bearing renewal have the new bearings being installed flush with the inner shoulder. This is incorrect and is highly likely to result in free play in the swingarm when re-installed back on the motorcycle.
-From 2005 to 2016 KTM used a 32mm O.D. PDS bearing.
From 2017 to present they use a smaller 28mm O.D. bearing. The Fungi Racing tool has drivers to that fit both these PDS bearings.
-The bearing seals are made from a thin metal and need to be installed square to avoid damage. The Fungi Racing tool is also the only tool which has a CNC machined seal driver which makes it easy to install the bearing seals square and to the correct depth without damaging them.
It is recommended that you only buy genuine KTM bearing kit. They will fit properly, are better made and will last longer. Contact a KTM dealer with your bike details to get the right bearing kit. It will contain everything you need to replace the bearings and seals
