Clutch or shifting problem/Not really sure
My miata was working just fine. Went and had the oil changed and put it
in the garage for a few days. Yesterday morning got in started it up, pushed in the clutch to put it in gear and nothing. It wouldn't go into any gear I tried. Was as if the clutch wasn't pushed in but without the grinding. I pushed the clutch all the way to the floor and nothing. It won't go into any gear at all. Now I am stuck and have no idea what could be wrong because it was working just fine a few days ago. It is really strange. It is a 1994 MX5 with around 90,000 miles on it. It isn't even driven that often. Any help would be greatly appreciated. Thanks |

Clutch or shifting problem/Not really sure
Thank you so much for all your help. I am going to try it and see how
it works. Thanks again. I really appreciate it. Natman wrote: > On 7 Jul 2006 13:06:53 -0700, wrote: > > >My miata was working just fine.

I think that you are missing a bolt down there. :-) The slave cylinder should have two bolts holding it in place, and these are 12mm, iirc, not 14mm. > You will also need a 10mm flare nut wrench for the pipe. A > regular wrench will almost surely round off the nut. All it really takes is thinking about using a regular wrench for long enough to round off the bolt heads on the hydraulic lines. ;-) > Fill the new cylinder with brake fluid before you bolt it up. Bleed the system and > you should be good to go. Ok, you got me here. Why would you need to fill the new slave cylinder with fluid before bolting it back on? Pat |

It makes bleeding easier if the slave cylinder isn't one big air bubble. |

I haven't replaced anybody's miata slave cylinder in at least a week, so one should be coming up soon.... Pat |

(Experience talking) Ok, I told Natman that I would try it next time, but.......I have done either 5 or 6 M1 miata slave cylinder replacements in the last 6 years, along with 2 clutch master cylinder replacements, so I am fairly familiar with the system as well. How much air are we talking about displacing? I know that it is not much, there is a small reservoir, small slave cylinder, and a very short hydraulic line. My last slave cylinder replacement had a speedbleeder so it was a quick process to hook up a tube and drop the end in a glass of brake fluid. I think that I refilled the small master cylinder twice before there were no more air bubbles, it used very little of the large can of brake fluid that I had. The entire bleed process took about 5 minutes on a completely empty system once the tools were gathered, how much time are we saving here? It has also been a very quick process when I have used a conventional bleed valve and a pedal-pushing helper. Even gravity bleeding takes very little time on the slave cylinder. With a speed-bleeder, the only extra work is a few extra pumps on the clutch pedal, which seems like it would be easier than bolting a part on in an inconvenient location while trying to keep it full of fluid. Even without a speedbleeder, we are talking about 3 or 4 extra turns on the bleed valve, not a lengthy or difficult process. Pat |
