Easily the best guide I have seen regarding the stiff gear change problem. Thanks for your time and effort :-)

I too had the same problem. But being in South Africa, I cannot get the parts locally, must have it posted from UK/USA or where ever I may find them. Our postal system is the pits, so I sought an alternative solution.

I stripped the whole shebang, removed the gear housing from the central consol, and took the cables off. Turned out that the back and forth cable was guked up and extremely stiff.
So I trickled thinners down the inside of the cable, behind the flexi rubber while working the cable up and down. ventually it come loose and after a lot of jiggling, I then followed the thinners with oil. Did this for another 20 min and satisfied it was loose enough I then reasembled the whole lot. Woks like a dream, if not better than new.

Took time, cost me nothing and problem solved.

Hope that this helps.

Great guide kiscix, thank you! I hadn't prepared for this so I just bored-out and greased one of my existing top-hats today, easily enough to fix my hard-to-find 3rd/4th gears.

I found a couple of steps easier if done in a different order:

10 (lifting the fuse box) is easy if you have left the four battery tray bolts in
17 (selector arm nut) is straightforward if done before the three selector plate bolts - you can simply use a torque wrench on it

Anyway, it really wasn't too bad a job. The retaining clips were the only tricky step - the far one can be levered against the selector plate, and wedging a spanner (19mm in my case) next to the cable gave me a surface from which to lever the near one. Refit with hammer

I had this done - 'top hat' bushes cost pittance and my mech did the swap - said old ones were stuck on had to sandpaper some of it off...

Previous to this the gear change was getting stiff and was very worrying.

I've heard of people selling on 147s thinking the gearbox is knackered when it was just the little bushes.

This was done on my car 2 years ago now approx maybe even more and is still smooth and free!!!

I knew what was needed for this as I did it some years ago - but when I went to local dealer they said the top hat bushes weren't available on their own, only the complete gear selector assembly.....anyone else had this?

I just polished up and lubed the swivel arm and the bushes, which vastly improved the issue - although not to perfect condition.

Unhappy Selector issue following replacement

Thanks to everyone for this excellent thread, it's made replacing the bushes a lot easier in a 2008 147 Collezione.
I have encountered an issue whilst replacing the selector which went in okay but now seems to be locked and although there is some movement it cannot be removed and does not move enough to refit one of the three 13mm bolts. Even connecting the cables and using the gear lever has no effect.

What is the issue likely to be? I guess the selector has been put in at the wrong rotation but to be honest I couldn't tell the correct alignment when it came out. There is a pin in the selector housing that it must align with but where should it go? More importantly, how can I remove this without force? Do I need to remove the pin from the housing? Will it come out using an extractor?

Any help or guidance would be appreciated.

Dear rgwm,

I am replying here solely for you and that the Dealership should know better than to hoodwink you!

I bought these said bushes before and have spent a wee while trawling through my email buying history (10th Feb 2014) and have found for you (bit late now perhaps) although you could direct this to your dealer and demand recompense for having to buy unnecessary kit.

My mechanic fitted this in February Devon weather and it worked a treat.
The old bushes had seized on and he needed to sandpaper the remainder off!

Still shifts a dream now to this very day!

When i looked at the pics of these bushes, i assumed they were rubber ...but they are solid plastic. Yes they seize on, but they're not meant to move. I took my 10 year old ones out and they looked fine. Does plastic degenerate?

I think that just cleaning and lubing the bar that runs through the bushes is probably sufficient. They are only a few quid so may as well, but i would say they were not a problem on my car .....and i could barely change gear.

The bushes don't seize on the shaft due to shaft corrosion, they get squeezed tight on the shaft by corrosion that forms in the alloy housing. You need to get rid of the corrosion in the housing bore to prevent this.
