help-Removing motor from GMC/Makita drop saw

[xgrain]

Hi All,
In our community theatre workshop we have a GMC db250 dropsaw. (from what I can tell its a Makita LS1214L clone).
It started making some funny noises especially on spin down which eventually got worse and so I went about pulling it apart. Thinking it was the spindle bearing this should not be too difficult to repair. However the front plate(as pictured below and ID part 91) does not seem to want to come free. Removing the two screws allows me to dislodge the plate a little. I can spin it about 25 degrees and pull it forward about 3mm then it just refuses to go any further.

Everything is stripped off except the armature(ID 16,17,18,19,20,21) and the 91 thru to 81.
Looking at the makita breakdown you would think the plate should come off and allow access to the bearing.
The bearing retainer(ID87) has two screws from the inside that screw into the the plate(91).
I would suspect therefore that the the retainer, spindle and bearing come out as one assembly.
The spindle, at least in the Makita, looks like a keyed push in fit into the bevel gear.

There are no circlips that I can see but I have given it a fair tug and just thought I would ask if anyone has had prior dealings.
Have I missed something or should I just man up and tug harder.

I have included the makita parts breakdown for clarification from

I have yet to find much info on the GMC on the net.

Hi All,
Well we got it apart. It does differ from the makita in that the bearing is behind the spindle not in front.
The armature must be removed first so the bearings,spindle and bevel gear assembly can come out in one.
Problem is there is no easy way to get the armature out. pretty much a one way on assembly push fit into its bearing.

However, with nothing to loose we put a hose clamp, nice n tight, around the armature and carefully using a soft material, wood or aluminium tapped around the clamp. the armature eventually pops out.

This revealed the spindle bearing had badly warn and thus allowed the bevel gear to miss mesh. The bevel gear was stuffed which pretty much ends the life of this saw as parts are not available.

What a waste, the gear is probably worth $50

that is why the saw was so cheap to begin with.

besides a new one is only $79 http://www.bunnings.com.au/ozito-150...e-saw_p6290179

I know it's hard but I'd bit the bullet and buy a Makita.
