I took a quick look under the centre console last night and found that the rubber gaiter was ripped, with a big hole in it !!!! doh ! Has anyone got the relevant part number and price , to enable me to order one from Mazda ?? (1/00)

Did you take off the upper one? This upper one is just a seal, but there's a metal disk beneath with a rubber bit in the middle, and this one actually acts as a pivot for the gear stick. On mine the lower one was *much* worse than the upper.

I seem to remember just under 20 quid for the upper one and just over 15 quid for the lower.

1) Make sure you have a large rag handy to catch a bit of oil.
2) Make sure you have 90cc of gearbox oil.
3) Get some 4mm tube to drain some turret oil. Some say a turkey baster. Ours wouldn't fit.
4) Remove the centre console after unscrewing gearstick.
5) Remove the upper gaiter.
6) Remove the lower disk/gaiter (you'll need a couple of extensions on the socket) and remove the gearstick. The bottom is probably very messy, and this is where the large rag is used!
7) Remove the plastic stays and either slide or cut off the old gaiters.
8) The new ones look like they don't fit. Use a little silicone grease on the black shaft of the gearstick and slide them down it. They expand to fit. Think "childbirth". :-)
9) Drain any old oil out of the turret that the stick fitted in to. At 45k and 6 years mine didn't have a single drop. Stick in 90cc of new oil.
10) Assuming you got the gaiters on the right way up, the gearstick will bolt back on as "the reverse of disassembly". ;-)
11) Make sure you got all the wires and insulation back around the gaiter OK. Check that the gaiters don't wrinkle and pop as you change gear.
12) Replace the centre console and have a beer.

Total time taken should be less than an hour and it's easier to do than describe! (1/00)

These should be the part numbers.

Boot dust change m514-17-480a - this is the bottom (little) one.
Insulator no1, change na01-64-481b - this is the top (big) one. (1/00)

NA01-64-481B
M514-17-480A
You need two parts, because the (more important) seal of the shifter turret will be gone, too. (1/00)
Buy one from Powerdrift, Jay NG's your man, don't pay mazda's prices.....! 07957 654284 or 01435 864573 (1/00)
For those who are going to change the rubber gear gaiter. I found some pictures which give you an idea what to expect at http://albums.photopoint.com/j/AlbumList?u=117212&Auth=false Look under Miata oil maintenance. (1/00)
General question .... If it doesn't leak out on the road, where does the original oil go to ? Does it just evaporate/dry out or drain into the gearbox. (1/00)
As it gets quite hot under there I can imagine that after a while some oil evaporates/dry's out, especially once the rubber gaiter cracks. (1/00)

What you need is Redline Synthetic oil in the gearbox - type MTL if it's really sticky - you can get two litres by mail order from Donutz (www.donutz.co.uk) or Demon Tweeks (01978 664466)

These instructions specifically for Mk 1 - never done it on a Mk 2

Gaiters - remove the centre console (5 screws - 2 in locker thingy, one under ash tray, 2 at front corners
- Unscrew gearknob, lift and wiggle console unit to clear fuel filler release etc
- watch out for and disconnect electrical connectors)
You will see heat insulator around gearstick.
Undo 4 bolts holding it and remove.
If it's old, it's toast - full of holes.
If it's not too bad, you can patch it up temporarily with gaffer tape. Preferably replace.
There is probably a very tight nylon ring holding top of gaiter - cut it to remove the gaiter.
Replace with cable tie, or if you're replacing gaiter, the new one has a ring fitted.
Under it, you will see top of gearchange turret.
3 bolts hold the top cover, which incorporates a seal/flat rubber gaiter.
Remove 3 bolts, and lift gearstick + seal.
If it has holes in it, replace.
Whilst you're there, check turret is reasonably full of oil. If not, refill it - not up to top - leave room for the gearstick gubbins. (It takes 90cc from dry - gearbox oil)
Replacing the seal just needs brute force to slide it off gearlever - doesn't look possible, but it is.
Reverse for replacement.
When you replace gearstick/top cover, you need to engage pin on gearknob pivot (stops it rotating).

Doing this a) keeps dirt out of turret and stops oil escaping (it disappears anyway - dunno where to)/ b) keeps centre console cooler (lots of hot air comes up through hole in floor and through holes in heat insulator/ c) improves gearchange ease and precision - don't really understand why, but it does. (1/01)

Er, the top boot; what does it actually do, besides keep the wind out? Both mine are split, but I feel its only really necessary to repace the bottom one. (3/00)

It (the top boot) keeps dust and noise out, and most importantly, heat. If you've got holes in the top boot you'll find that the centre console gets very, very hot on a long journey in warmish temperatures. If you need to penny pinch, you can fix it quite well with Duck tape. (3/00)
You mean the centre console isn't *supposed* to get warm/hot?? I've noticed that it got quite warm...even with the heater off...I thought this was normal (?) My audio tapes get quite hot if I've been on a long drive...do you think this could be due to a cracked top boot? (3/00)

You mean the centre console isn't *supposed* to get warm/hot??

Warm - yes. Hot- no.

I've noticed that it got quite warm...even with the heater off...I thought this was normal (?) My audio tapes get quite hot if I've been on a long drive...do you think this could be due to a cracked top boot?

Yes - it's worth a look (They dont so much crack as disintegrate- you'll probably find big tears all round. It's a sort of convoluted gaiter thing, like a fwd drive shaft boot) Also make sure the bottom holding plate is flat, not warped to leave gaps underneath. (3/00)

 

Mine had so sound proofing material underneath, but some UK cars seem to have this. Will this make any difference? (3/00)
Some - but I doubt it would do much to keep heat out. Basically it's exhaust and engine heat I think - the exhaust pipe is fairly close to the gearshift hole, and engine heat will tend to be piped along below the tunnel as well. (3/00)
Does anyone have the part numbers for the two rubber gaiters that go on the gearbox, Both of mine are looking worse for wear!! Anyway I'll need the one that goes from the turet to the gearstick and the one that goes from the body to the stick, can I get them anywhere apart from my local (un)friendly mazda dealer (the car's a eunos) Also how much oil goes in the turret on the box? (9/00)
The bottom one is called Boot Dust Change Lever (or Change Lever Dust Boot in English) - it's M51417480A - list price a year ago was 14.90 (+ VAT). The "middle" one is called "Insulator", is NA0164481B and the list price was 20.38 (+ VAT) a month ago. The lower one is on the microfiche of the gearchange, etc, but the middle one is with the pictures of the central console. You'll have to get them from your friendly local Mazda dealer - just don't tell them they're for a Roadster if that's a problem. The turret takes 80-95cc of oil (from dry) (9/00)
Yesterday my gear stick went odd! sideways and up/down movevment way past the norm, you could push it about 4 inches past the normal stop to the left, and gear selection was push it and hope. after the 3 hour drive home it suddenly came back to normal? (12/00)

Sounds like the rubber boots around the stick are falling to bits. Without these gear selection can be iffy, and the lower one holds the gearstick in place!

Unscrew centre armrest (half a dozen screws, check in storage box and under ashtray), whip off gearstick and ease console out (careful of window switch wires and fuel/foot release levers). Unbolt the upper rubber boot and then you can see the lower boot. 10mm with a long extension will do it.

It's only a five minute job to get to this stage, so you can take a peek and report back. (12/00)

Something similarish - but worse happened just after I got mine. I wanted to do a quick U-turn; whipped down to 3rd & the gearstick stuck there. It could be forced, but wasn't happy. Seems that the gearstick goes directly into the gearbox, which is held by an alloy bracket. This had cracked (probably before I had it 'cos there was dulling around the area) & jammed the stick. Garage said they had never seen this before, but happily replaced the bracket. So get yours checked - it may save an `embarrasing' stop. (12/00)
