Default update on pathfinder rebuild

While waiting for parts to be returned, attention was turned to the power unit.What surprise I got there!!! The gearbox mainshaft seemed to have to much endfloat, so the gearbox was stripped and the horrors I found seemed to be insurmountable at first. New mainshaft, outer bearing sleeve and rollers,inner bearing sleeve and rollers and the dreaded draw key were required.
Somebody had decided to replace the roller bearings with ball bearing race's. this envolved modifying the r/h bearing outer sleeve to take a small ball bearing race, by hand with a rotory grind stone!, but worse was to come. The left hand sleeve had been removed and the machined hole was enlarged for a ball race with,that's right, a rotory stone again!!! Just top it all ,the mainshaft had been reduced in diameter to fit into the bearings by grinding down the bearing surfaces using a, wait for it, BENCH MOUNTED GRINDSTONE!!!!!!!
At first I thought this might be imposible to overcome but , with the power of the internet I found a mainshaft and l/h bearing sleeve along with a draw key in America ( motorwest) and they were bought. The r/h bearing sleeve, rollers for left and right bearings and bearing thrust washer were obtained from RBO in Austria. Once the l/h bearing sleeve had arrived I then turned my attention to the left case. Armed with the bearing sleeve and case a visit was made to Merlyn/CRD engineering to talk about what could be done. They cleaned up the hole in the case and the machined a sleeve to fit and hold the bearing sleeve.
Now all I have to do is rebuild it, hopefully with a new 5th gear pinion, if I can find one. Not had much luck in that area at the moment, so if anyone has a new/used 5th gear pinion for a pathfinder PLEASE let me know(24 teeth,diameter 52-53 mm)[there are 2 sizes for this gear]
Now, for your delectation, here are some pic's, old on the left ,new on the right, in first 2 pic's.

Mike.

Default A little bit more

As you can see, the progress of the rebuild has gone a lot further forward.I was hoping to get it compleated for Battlesbridge but the re-chromed parts have not yet come back. So I'm left to do some fiddleing with it.
