Clutch with no resistance - no gear engaging (help required)

Recommended Posts

I have recently purchased a 1966 TR4A and whilst the car was running well, when I last wanted to drive the vehicle the clutch had no resistance and will not allow first gear to engage. I cannot drive the car, so am hoping that someone maybe able to advise on whether this is a clutch cable failure and if this is easy and cheap to fix (for a novice, but someone is is fairly practical)? Could it be something more serious requiring the attention of a specialist? If the latter, does anyone know of a reliable mechanic around the Maidenhead area? - Thanks in advance.

Hey Jenky,

 

It's a hydraulic clutch.

 

No resistance is likely no clutch fluid

 

Probably means clutch slave is leaking... easiest to buy a new one rather than mess about resealing old one..they come up on ebay often.

If it's not hydraulic (check if you see the arm moving on the end of the cross shaft) - it could be a sheared pin on the cross shaft - gearbox out job .

Good luck and fingers crossed it is something simple

You will need to see if the clutch release mechanism is working. Ask someone to operate the clutch and check for good movement of the clutch slave cylinder and fork movement.

 

Is your clutch master cylinder topped up? If not it may have a leak from the MC or Slave cylinder. In that case you'll need to re-seal or replace and bleed through. If not as per above comment with sheared cross shaft pin.

HI Pjenky, (what is your first name)

welcome to the forum.

As mentioned - it is Hydraulc.

Check the master for fluid - if it needs filling you will need to establish what fluid is required (DOT4 ethylene Glycol of DOT5 Silicon) do npot mix they types.

Take two or three tea spoonfuls from the reservoir and mix with a teaspoonful of water - they mix it is DOT 4. If it doesn;t mix it is DOT5.

Top up check for leaks.

 

Press the pedal and see if the operating lever is moving rearwards - get underneath the lefthand side of the car and you should see the lever hanging down.

 

If it all looks OK it could be the taper pin that locks the operating lever to the fork that pushes the release bearing

 

Get yourself a Moss Catalogue or look at their Web Cat http://www.moss-europe.co.uk/

Item 16 is the taper pin

If the pin is sheared it will be gearbox out.

 

If you are a member of the TR Register then contact the Thames Valley or Windsor forest Group leaders and they may be able to give extra help or know somebody near you to assist.
