Hi Kindfreak,
This seems to be a problem on this model saw.We get a couple of these each year.It seems as if the arm holder gets slightly link removed most cases the bearing box will need to be replaced. But even replacing the bearing box the saw seems sticky.To fix this some of my customers have started using this lock spray called Houdini and swear that it makes all the difference in how well it slides. link removed I could give you more information.Hope this helps.Good luck.

Hi Shane,

The blade wrench is part #782232-8. The fence, item #170, is one piece for both the left and right sides. I am guessing you are looking for the right side fence extension. It is part #153898-5. Both parts are available from http://www.ereplacementparts.com.

Thanks!

i worked it out, if anybody is interested:

remove blade, remove brushes, disconnect laser, remove 4 screws mounting the motor onto the chassis, remove motor housing, remove 2 screws which hold the armature in place, remove armature, remove arbor assembly from the blade side, remove small bearing from the back of the arbor assembly (puller required), remove cir-clip, remove bevel gear, woodruff key, seal and washer, remove arbor and bearing from casing, separate bearing from arbor shaft, re-assemble in reverse order, fitting new bearings, bevel gear assembly requires compression to re-fit the cir-clip. good luck
