Clutch return spring

[vincereynard]

In the ever evolving tale of what Spyder has forgotten / bal*'d up / not bothered to do.
It would appear that the clutch return spring is missing.

What would be the effect of this? Does it really matter?

At the moment the gearchange gets progressively worse the warmer the car gets. Its fine when cold.

................in which case we look at the function: these springs keep the release bearing where it should be: not touching the clutch plate and therewith wearing to the point of quick destruction! sandy

Vince - to paraphrase el-saturn it is really important. From memory it is similar to the clutch and brake pedal return springs in the footwell.

..and keeps the operating arm in contact with the push-rod,in contact with the piston and stops any parts from going missing...

Thanks for the replies.

Drat! I suppose that means I'll have to do something. If only a quick temporary bodge.

On a side issue, does anyone know if the spyder chassis can be jacked up at the front under the vacuum tank?

I would have thought the car would not be driveable without a clutch return spring . . . but you mention the gearchange is getting progressively worse which implies it is driveable. I might be missing something.

The springs are available from the usual suppliers.

Hi Vince

I have on occasions jacked up my ?lan +2 on the tubular section that houses the vacuum reservoir. Put in soft padding to stop any gouging or cutting and or make a fitment to hold the tube so it don't slip off. The spring is readily available. It goes on and comes off quite easily and has to come off for the gap setting of the adjuster. I got my spring from Sue Miller.

Hope this helps

best of luck

The finger springs on the clutch pressure plate will cause it (the clutch) to disengage. This spring is really about getting the hardware that forces the release bearing into those springs and the bearing itself back to a relaxed state. It is important in this role but not critical. Without it, as noted the release bearing may stay partially engaged, wearing it out much sooner, and the bits of the engagement linkage on the outside are free to wiggle back and forth and maybe fall off.

You can find a spring like this at any hardware store, it only needs to be strong enough to return the slave piston to its resting location. A stronger spring will increase pedal effort and pull things back more quickly.

If necessary I shall make up a wooden U to fit over the vacuum tank. This is very much a Plan B as I have another idea how to raise it up to a working height.

As it happens I was given a spring my the recovery service mechanic to solve a problem created by a previous, somewhat more dangerous , example of poor assembly.

As long as it is short enough to pull the release lever back, it will do for now. I'll add a "proper" spring to the growing list of bits to get.

please don't jack it from under the tank. Previous owners ruined my chassis doing this.

With a Spyder chassis?

[elj221c]

Tis fine on a Spyder but because it's round I tend to use the junction of the tube and the turret if just raising one side.

[vincereynard]

It probably will not be necessary - I have a cunning plan!

Ill post pictures of my bent spyder tank when all this Xmas booze wears off. Merry Xmas!
