This pictorial deals with the changing of the final drive fluid in the rear drive.

The procedure is broken out into four stages:

  • The first stage is the preparatory work to get the bike to do a final drive fluid change.

  • The second stage is the rear drive fluid draining

  • The third stage is refilling

  • The fourth stage is the re-assembly

Aside from standard mechanics tools you will need:

- T25
- T40
- T45
- T50
- 6mm Hex
- Assorted 1/4" and 3/8" drive extensions
- Torque wrench

Bike Information:

2009 KGT 1300, ABS/ASC

The 2009 model rear drive does not require it to be "dropped" to change the fluid as there is a drain plug installed.

Also on the 2009 Model the fluid is replaced thru the fill hole instead of the Speed Sensor

Stage One - Preparatory Stage

The preparatory stage consists of:

  • Putting the bike on the centerstand on a flat stable surface. - not shown

  • Remove both saddlebags - not shown

  • Taking the muffler off

  • Taking the rear wheel off

Once the rear wheel is off the decision path for either the fluid drain or the spline lube can be determined.

Once the muffler clamp is loosened you can remove the muffler hanger bolt.

IMPORTANT NOTE - hold onto the muffler as you remove the hanger bolt - if not it will fall.

Once you have removed the muffler the exhaust system is wide open - so I stuff a rag to prevent any introduction of debris.

IMPORTANT NOTE - the wheel bolts have NO lubricant or locking material of ANY type applied to them. They come out dry, they go in dry.

Once the caliper is removed you need to get it out of the way so you can access the drain bolt and put a catch can underneath.

I wrapped the caliper so it would not get scratched or scratch the frame.



If you are planning to lubricate the driveshaft splines as part of the rear fluid change go to this link now Spline Lube Link

If you are just going to change the final drive fluid - continue below

Using a T-45 remove the drain plug and have a suitable device to catch the waste fluid.

A very useful link you can use to locate recycling centers in your area is this one - special thanks to Ted for finding and providing
