Thanks for all your replies. Richard thanks for the link to the pump I will look into that.
Sewin would you believe I ordered and paid for the Lodexol oil about an hour before reading your post. If there is a 50/50 chance I will pick the wrong one !! Still, it will do for this time around. I did speak to the tech team at Morris before purchase as my main concern was its compatibility with a non LSD axle and they assured me it was. They said I was simply paying for additives I did not need.
On the subject of annealing I agree with you and CooperMan, as he says, you are guaranteed a perfect fit. My only point is, in the photo I referred to on Gomog showing the drain plug bolt, the washer appeared to be aluminium not copper. If that is the case according to the internet the way to check you have achieved the correct temperature for annealing aluminium is, first hold the component near to a lit candle to cover it with soot. Then when heating with a MAP torch wait till the soot disappears then allow the component to cool. Any comments?
Once again thank you to everyone for your replies.
