gear selection

Standard & modified running gear

gear selection

Postby cococola » Sun Jul 08, 2018 8:53 pm

well I went out today and did about 40 miles, during the journey my gear selection got harder to the point that I have to really pull into gear.
Im wondering if I have a hydraulic problem or if my clutch has suddenly got worse on my journey. I have very little travel in my pedal before biting point.
How can I check please, I know the gearbox is fine?

Well if it is a standard car it is not a hydraulic problem as the clutch is rod operated.

In theory it is very simple press the pedal the rod pulls back on the clutch arm and it all works fine.

In practice the clutch rod can be adjusted for normal wear of the carbon thrust bearing as there is a nut and lock nut on the end near the gearbox.

Unfortunately as well as that there is a bar between the chassis and the gear box so the bushes at either end of that can wear.

The bar has two arms dropping down one connects the rod already mentioned and the other is connected by plates to the clutch pedal.

The holes in the arms can wear, the holes in the plates can wear and the hole in the clutch pedal can wear, all of which will increase the pedal travel.

None of it is particularly difficult if you can safely jack the car up and have a look.

Just drive it first, as if it is ok when you start it and then gets worse it would tend to point to a gearbox issue when warm in which case check the gearbox oil level as the first step.

If still as bad when you finished the last journey then suspect wear in clutch clutch linkage and don't push your luck. I had the right angle of the clutch rod break off because I had not spotted the wear soon enough.

Went to work today and the gear selection was poor all of the way so at lunchtime I got access to a ramp and the adjusting rod was out on the maximum adjustment.
The locking nut had worked loose over a period of time and after adusting the nuts in on the rod I had a clutch again, allbeit not as decent a pedal as I would like.
I will stick to plan B of replacing the clutch in the next few weeks as I want to enjoy the Moggie as much as I can with the roof off while sunny.

Nice modification far better than the original.

Over here it is possibly easier to get 6mm or 8mm Heim/Rose joints and threaded bar.
