With a screwdriver and hammer tap the snap ring off the end of the shaft, it sits in a groove.

Fit a 3 inch 3 leg puller onto the end of the shaft and link the legs under the hub;

My puller didn’t have a cap on it so I placed a small 10mm

Wind the puller in slowly, don’t go too mental on it or again it’ll pop off.

Once the hub is off 5th gear, the synchro and the spacer ring will slide off easily.

Fit the hub to the end of the shaft with the thickest centre ring of the hub on the outside, if you look at the second picture you will see that it is actually higher than the toothed part of the hub.

With a 22-27mm 1/2inch drive socket and extension drive the hub onto the shaft, I used a 22mm deep impact socket and it was just big enough
