filling the void, is a machined step in the shaft itself, whether using the peak performance style layshaft or the one with the pin, thats step will be there to take the place of the missing rear layshaft hub, to hold the outer 8x14mm bearing. Now...it rained tonight with lightning so i did not log on to the net tonight..until now. i was doing a week long download and compilation of various vintage tamiya and kyosho videos to put on a DVD so that i can watch them on my big screen LCD TV, but since it was a thunderstorm and couldnt log on, i spent about 2 hours plus on the layshaft design. i already got a working idea, have a look at the pic.
PIC 1 shows the layshaft assembled with the B4 slipper plates, spur gear, and spring in place. Note the spring is set at zero compression so thats why the nut looks like its far out at the edge. Also slipper pads not shown but you get the idea.
Pic 2. The layshaft only from slipper spur gear side. note the B4 end that will work perfectly with the B4 parts. the "wall" after the flat to hold the B4 plate, is to stabilise the B4 plate becuase the end of the B4 plate will sit on this wall. the diameter is 8mm. then it goes to 10mm, then back to 8mm to hold the inner 8x14mm bearing.
Pic 3. The layshaft as seen from One way side. Notice its as if the rear hub is bonded to the layshaft, peak performance style. So you can place in your original pulley for the rear. The circlip groove distance is exactly the same as the original ZX shaft. Asembling this shaft is by placing the 8x14mm bearing inside , then slot the layshaft from the spur gear side of the gearbox, next place in the rear pulley, then place in the thrust bearing parts, then lock your e clip in. then place your front pulley and one way hub, the end washer and the M3 Nut. Voila.
If you notice in the first picture that the hub looks like its somehow joined with the 4mm layshaft, well the actual part wont be like that. it will be one complete piece. In solidworks there is an option to create all the parts seperately then joined them together in a file part, by inserting a part into a part, thats why the shaft looks like its made of 2 pieces.
That means the stock material will follow the largest diameter on the part which is 10mm. then will be machined down to 8mm steps on left and right side, then to 4mm to place the one way, then to 3mm to thread the ends. You get the idea?
So if you guys got any suggestions,questions, objections, praises
