Continued with the assembly of components into the box.
Strings in position to lift layshaft gear cluster into final position once rest of shafts in place and thrust washers stuck with a little assembly grease into position. The manual says fit the reverse gear later but I find it easiest fitting now before placing the cluster gear in the base of the box so you are not fitting it with the layshaft gear lying loose in the bottom of the box.
Layshaft gear and dummy shaft and needle bearings and washers and after assembly
Layshaft in base of the centre casing, need to be careful not to loose washers out of layshaft or displace the thrust washers in the casing as you drop it into position after passing in through the rear of the casing. You can see how tight the clearances with the Quaife gear set first and second gears on the cluster gear with the reverse gear shaft and collar for the reverse shift fork and why they need to be machined down
Now input shaft assembly can be fitted through to front of casing from rear. Snap ring located in bearing groove and front seal carrier bolted into place to locate bearing. Paper gasket and my preferred Loctite aviation Gasket cement and sealing of bolts threads with thread locker to prevent leaks through this front seal carrier. Manual says protect the seal by taping the splines as you fit the seal carrier as its diameter is smaller than the splines but this only applies to the earlier gear boxes that has the smaller diameter seal, the Quaife gear set and seal carrier have the later larger seal.
Rear gasket in position stuck on the rear face. Make sure the reverse gear shaft alignment key is located to fit in the slot in the rear extension housing and the same with the lay shaft when that is fitted
Gearbox output shaft cluster fitted, remember to fit the bearing and top gear synchro onto the input shaft before fitting the output shaft assembly into place. Also the layshaft lifted up and dummy shaft tapped out with longer layshaft. Ensure the thrust washers have not moved and the gear is lifted to align the shaft with the casing holes so the dummy shaft can be tapped out.
All the shafts now in position... to be continued
cheers
