As far as books are concerned the one 'must have' in my view is the 750 Companion. Doug Woodrow's manual is useful too. John Platt's Catalogue available in repro now I think is useful for understanding how bits go together and the different variations.
Everyone has their own views on oils! I use Duckhams 20W/50 in my engine, and have done for decades. Only ever use engine oil in the gearbox - again 20W/50 or perhaps SAE 30, but nothing heavier. In the back axle I use a straight (non-EP) SAE 140 oil. I use Castrol LM for most greasing applications. Some advocate using oil instead of grease for kingpins, just to make sure it penetrates well.
The only thing I'd add is be careful putting a modern detergent oil in an engine which has been run a long time on non-detergent oils without a rebuild, as dirt can be dislodged.
I feel confident someone will now tell you to use non-detergent straight SAE 30 or 40 in your engine. It's your call but be careful warming up, which is when 90% of bearing wear occurs.
Hi Chris
Thank you for your reply and warm welcome. I’m not great at technology so please excuse any mistakes.
The advice is precisely what I had hoped for. I havnt stuck my head under a bonnet since cars became too complicated, but have thoroughly enjoyed playing with the A7, and hope to strip it all down and put it back together.
Very grateful for your advice
Mark
