Hi, I am posting what I have provided to Delbs. Not so much doco but rather a set of instructions.
The instructions that I followed is what
"rayintheuk" one of our forum members provided way back in Oct 2009. The blokes name is Ray Girling and has provided many instructions about taking the router apart and assembling them.
Here is the set of instructions courtesy of Ray - It works as I have used it.
1) Remove the dust shrouds, if still fitted.
2) Completely remove both carbon motor brushes, noting their position and orientation for replacement.
3) Wind a suitable piece of string or light cord around the motor shaft so that when you pull it, it will revolve the shaft in the opposite direction to that of normal travel (see the arrow that indicates normal rotation on the base of the router for confirmation). **
4) Pull the string or cord just as you would to start a gyroscope and when the shaft is spinning, swiftly push in the spindle lock by hand. The shock should release and unwind the collet chuck assembly. If it didn't, spin the shaft faster.
5) Replace the collet chuck with the new style, winding on the upper part (with the three indent holes) as tight as you can by hand.
N.B: Do NOT try to tighten the whole assembly by using the wrench on an empty collet.
6) Plunge the router and mount a straight cutter in the ½" collet.
7) Replace the carbon brushes in their original orientation and fire up the router. Plunge the bit into a piece of scrap hardwood to ensure final tightening of the assembly.
8) Replace the dust shrouds if you use them.
** If you have an airline, you can use this instead of the string or cord. Just point it at the cooling fan (at step 3) above) to spin the shaft backwards. Don't go mad with the speed of rotation!
I have sent Ray a PM as a courtesy that I shared his instructions. He has been more than helpful regarding the Triton routers over the years.
I used the string to unwind the chuck ( what Ray refers to as the motor shaft). It took a few attempts because the string I had was weak.
So a strong piece of string will make the job much easier.
Believe me, these collets are far superior to what you have on your router. Using the router becomes a pleasure and much safer and also ensuring no slippage of cutters to ruin the workpiece.
Oh, and you need to modify your spanner to fit the new collet. What I did was to file the my spanner to 24mm taking a little off on each side.
Woodcraft in the USA have a nifty spanner to fit the new collets.
