Some time ago I posted about a leaking rear axle. When taking it apart, I realised that the Rear Axle Housing Cap and felt washer was wafer thin and needed replacing. Parts finally arrived. Question- is there a trick (apart from a piece of timber and a heavy hammer) to properly seat the Cap to the required depth to allow the brake drum and wheel hub to seat properly? Second question - and a tad embarrassing - when disassembling I forgot to note the positioning of the key. Where does the tapered section go? Seems that there are four possibilities.

Appreciate any advise that can be provided.

Cheers
