Power torque tools.

Crank Pin.
The genuine tools for undoing the Power Torque crank pins are expensive.
You can make your own out of a couple of ordinary sockets for around $20 each. I used 3/8 sockets as thats the set i mainly use and thats what my torque wrench is.

For the early model with the for slots you need a 20mm 12 point socket, i bought mine from bunnings.
Mark it so you leave points at 4 even spots around the socket and get into it with a grinder. A 1mm wide cutting disc and a steady hand is all you need. i suppose a dremel would be good too. You may have some luck fine tuning it with a file toward the end.
I started out with a crappy tiawanese socket, but it broke so i bought the kingchrome socket. Had no trouble since but i have not used it much.


For the later model with the two flat sides you need a single hex 21mm socket. I special ordered mine from the local bearing supplier. Remove everything but two sides of the socket. Most sockets have a tapered leading edge, i ground mine down a bit so the edge against the socket is a square corner.
This one is a bit more tricky, to locate the socket on the pin, i got a bolt with a 21mm head and drilled a hole in it so that it will fit nicely over the pin. It does work, but its not central, probably not square either, thats a bit hard in a drill press, especially in the vice i have, I'm going to get a friend to do it in his lathe for me. Once i have that done i will pein it over or something so the nut is permanatly fixed into the socket.

I will probably do the same with the one above for the early models. They can be very tight. If thats the case i advise hitting the conrod with a hammer to break it, removing the crank and then using other means to remove the crank pin.

Starters,

On the early starters they have a 'stuffer block' held on with two screws. Remove this, and the spring clip and you can hold the 'throw out' in the vice and undo the nut to pull the starter apart.
If you do not take the clip off it gets caught.
Heres on with the block off, the clip is a bit deformed.
Clamp it either side of the rectangular bit.

On the newer starters this 'stuffer block' is cast into the starters.
This ones a bit crusty looking, it was the closest one i found.
The clip is different to the earlier ones.

I made up a holder to hold the 'throw out' to get the starter apart.
Clamp the holder in the vice.

Its a bit of a ballancing act but you can get them undone and fixed.


Another handy thing is a washer. Something with a hole in the middle thats the same size or a bit bigger than the hole in the blade disc and the same thickness or a bit thicker.
When putting the motor back together with new bearings you can pull the whole lot together with blade disc nut.


If one of the Moderators could make this a sticky that would be great.
