Last night I assembled the gearbox, here the parts are cleaned and ready to be fitted together.
The housing was cleaned as well and copper washers were fitted behind the oil plugs, the triumph piss oil for both of them I there is no need for this one to leak as well.
Over the years I have made a bucket full of special tools for assembly and disassembly of the engine, here is one for fitting the rear bearing to the pinion shaft.
Here both shafts are in place in the gearbox with the new ceramic bearings fitted.
The turbine bolt lock is kind of special, a 2mm stainless wire is inserted in a hole drilled through both the insex bolt head and the turbine nut flange. Locking washers or Locktite is a bit no no for this since dropping the turbine wheel at 32.000rpm would be a bad idea...
I used a cylindrical punch to make a dent in the wire inside the insex head so it is locked in place, then the ends were bent outside the flange as well so now I consider the turbine wheel secured beyond all doubt.
The whole power turbine section assembled, hopefully it will stay that way the rest of the year as well.
After that I could fit the engine in the frame, it looks much better now with some paint on the frame and gearbox.
Next up is to flush the gearbox internals with kerosine to get rid of the last bit of bearing grease and any eventual particles that got in there during assembly, will get to that later this week.
Cheers!
