Hannibal: There are two ways we can do this: the easy way and the hard way. In a few minutes my friends and I are going to come down on you like your worst nightmare. You're gonna wish the Earth had opened up and swallowed you whole.

Matt's car is now my car :0)

The Spec in a mag is not the exact spec of the car!

Think forged pistons, hybrid t3, super head, huge IC, lots and lots of love went into it!

Re the comments - Every A+ box I've seen has RTV rather than gaskets...

Never yet experienced a broken / weak synchro spring, but for the pennies they are to replace, and given that they'r constantly under compression, they will - arguably - weaken over many years and cycles of operation. How much totally depends on the quality of the spring in the first place. I guess if they're cheap enough, replace. I never do - but always compare the free-length and give them a little squeeze to see if any are ridiculously weak.

The large bearing in the box - well these are usually the first to let go let's be honest. If I was doing a regular 998 tranny, and this bearing looked fine under detailled inspection, I would re-use - same with any bearing. I always replace it whenever my engine and box are apart however, no matter what...

Can't comment on the 'thirdly' as I've no idea what is being discussed. Initially I thought laygear, but it can't be if 40 thou is being stated by Vegard...

Given most of what I've seen of adrian's work, it'll be a pretty good guide I suspect?

Somethign I'm too aware of; You have to account for the mag staff reducing the number of words - often changing the 'meaning' or intent of a statement unintentionally as a result. Typo's also happen.

Anyone want to scan and send to me?

All 12 of the boxes I have use RTV.... not seen gaskets at all to be honest.

Most people hammer the centre bearing out... I wouldn't reuse it after that. I wouldn't even if taken out with EXTREEM care... they usually are the 1st bearing to fail IMO.



"Has anyone one here ever had trouble with weak selector springs in the syncro hub? "

Yes most boxes that pop out of gear are due to this! You can make 1st/2nd changes feel very nice with some stiff springs :)

Maybe things are differnt with nasty A+ boxes :)

I've only worked on three or four A+ boxes, and all of them has gaskets. We've got to remember that there was rod boxes before A+ as well.

I just feel for the right click on the syncro hub. If it clicks positively, then thy're OK.

Number three is synchromesh ring to gear clearance.

So you've seen broken weak springs in the many A+ gearboxes you've rebuilt Alex?

In every A+ one i've done - Never seen a broken spring.

seen a fair few really soft ones... 1st give away is the dull clack of the hub, rather than a nice sharp click.

Not loads, but enough to warrant changing them.

Adrian measure them as they are SHITE quality... a good one takes about 4kgs just b4 coil bind, but some goto 5ish. Other manage 1!! A bit range, hence AC tests them, hes a bit anal like that!
