May need to remove wear step to simplify readjustment. if the bearings are unmarked it is an extravagance to replace. The pinion bearing must have minimal clearance. If an earlier pinion with a ball race prudent to replace. What state are axle tapers? The adjusters are a wonderful convenience. Most diffs have pressed in bearings and fixed shims; all fine with an assembly gauge but a nightmare without.Adjusters handed.
(It is common to shim used a/c races to just eliminate any play. But recent reprint of instructions for earlier diff stated that the pinion a/c outer rings shoud not be rigidly clamped. Dunno if anyone actually applies, or applies to later, but this would seem to not suit shims, as likely to wear )
What prompted this is all very simple. The car/chassis/all components have stood for a long long while prior to me buying the lot, from which I'm building a special, so I decided as a matter of course to strip the axle down and inspect...plus of course to learn as I'm new to Sevens (had this lot for a year or so).
had I checked Bill Williams A7 Specials book page 81...there was the description of how to do it! marvellous. I have Woodrow too, but curiously though very good, I find that it rather implies that one ought already to have prior knowledge in some cases of aspects of these cars, and I don't and this must also be the case of us all initially! Woodrow didn't say how to get the spring wire circlips out.
May I make a general observation, and this might already be the case somewhere on this overall site.
What would assist newcomers might be a very brief list of available and out of print books, maybe with photos of front covers etc and a brief description, so that newcomers and anyone might then look around for such books?
Bob, this might be right up your street (which'll save on bus fares to quote the Goons!), the idea of a compilation of further ideas etc, I know that the Austin Seven Companion exists ( I have one), but perhaps a more comprehensive list of which book to look up for what question/context/problem, might be useful.
Clearly, I could do this idea myself, but I haven't yet come up with sufficient questions/context/problems, and I simply do not have the knowledge yet of the Seven.
A list of books alone would be very useful (I have 11 books on the Seven so far).
If I've stated the obvious and all of this exists, just kick me into the bushes!
Just an idea!
