Hi All,

 

I have a 1976 998 engine sat in my shed which is in need of a refurbishment. I will be doing this myself, just to expand my knowledge of the A series engine.

I intend to start from the gearbox up, but need some better reference guide than the good old trusty Haynes Manual.

 

Please can someone recommend a good manual, online guide or even a DVD, to A Series gearbox building.

 

Thanks in advance

Workshop ones.

gearboxes especially old ones are built with stronger bearings and baulk rings so I doubt you will need to strip it down.....unless you know it has a problem

Thanks A-cell, they are exactly what I was after. Just a little more specific information than the trusty Haynes manual.

Unfortunately mk1leg, I don't know the history of the engine and gear box, just the year and its a 998. I bought the complete engine for £50, that had been sat in the back of someone's garage for 10 years.

How more specific? It has all the settings. What thickness of shims. And his to do a full strip and rebuild.

Never needed more than that in the last 30 years.

Yes there are a few things that can be done slightly differently. But never had any issues with the info in my Haynes's for the Mini.

The haynes manual is almost a word for word copy of the BL workshop manual anyway.

 

But sometimes it's better to actually see someone do it as well as read how to do it.

And the newer the Haynes, the less info it has in it. 

If I remember rightly you need the light blue one or the Metro one, not the dark blue one.  .

Just found 'Mini Expert issue 1' written by Keith Calver of mini magazine. It has a massive section on Gearboxes including strip down and rebuild. It has excellent pictures and multiple diagrams, so going to digest that before I start.

 

Shame I didn't get issue 2......

There's quite a few YouTube videos covering gearboxes, worth watching those to backup what you have from books.

 

I have a later Haynes manual and it says very little about the guts of the box, however I also have an older Autobooks manual and that covers it all rather well. If I'd have paid more attention reading it I'd have spotted the 'lock 4th and 1st' tip rather than using a spare motorbike gear to do the same job. :mmkay:

I have to say, I haven't yet found a workshop manual which shows or tells what to look for when overhauling a gearbox, some show how to get them apart and reassemble them, but I've read show what to look at when they are in bits. The older Factory manuals touch on a few bits and that's the best I've seen but I recon still falls well short.
