A short blog on these as many people don’t seem to know the facts, as the supplier of these to MX5parts I do \ud83d\ude42<\/p>\n\n\n\n

The problem we are fixing arose because the original 6 speed plastic bush doesn’t fit very well. It never did, right from new. It doesn’t wear out, it just never fitted properly. The NC1 ‘box has a different size bush to the NC2\/3 type, if you look carefully at the picture you can see the difference.<\/p>\n\n\n\n

Originally I got a fellow enthusiast (thanks Archie) to check out the 5 speed bush to see if the same applied, I sent some precise measuring equipment and he advised it fits perfectly. Since then I checked a few more and can confirm it doesn’t wear and does fit fine.<\/p>\n\n\n\n

So to sum up; buy a bush for a 6 speed to make those changes more precise, don’t waste your money on a 5 speed one. Buy from MX5parts or me to be assured absolute precision and quality, buy elsewhere for questionable quality – you won’t know the difference as you can’t measure it. I only know it can be made worse, not better, as the ones we sell are a perfect fit.<\/p>\n\n\n\n

Where does it go? It goes here:<\/p>\n\n\n\n

The gearshift bush (4) clips onto the lever ball (6) and sits into the hole in 5.<\/figcaption><\/figure>\n\n\n\n

Tips for fitting: There are plenty of online guides, Youtube etc. One thing I would add is put the new bush on your finger and drop or push it into the hole in the turret. As it’s a very precise fit you may need to rock it around a bit before it slides in. Then put the lever ball into it. Don’t drop it into the turret elsewhere! You’ll spend ages with a piece of bent wire trying to find it. Don’t ask me how I know this.<\/p>\n\n\n\n

There is also mucho confusion about turret oil. It is<\/strong> separate from the main gearbox. It needs nothing more than the same oil you put into the gearbox. I would just put enough in to cover the moving parts you can see, no more. There is no reason to put special magic fairy tears \u00a350\/litre oil in there. All that lives in there is a few levers and joints, nothing high tech or rotating.<\/p>\n\n\n\n

Is your 6spd gearbox notchy and difficult when cold, but ok when warm? This bush will not cure this problem, it’s something else. <\/p>\n\n\n\n

We have our own blended oil for this problem you can read about it here: http:\/\/www.duratecnc.co.uk\/?page_id=348<\/p>\n\n\n\n

The 5spd is less prone to this problem, but this oil will work in that too if you want to make it even smoother when cold.<\/p>\n","protected":false},"excerpt":{"rendered":"
