Hi Folks
I'm new here and have never used forums before so am not sure of correct etiquette and a little embarrassed to be begging for help and advice already. However advice is what I need so here goes. The vehicle is a 1964 series 2A 88
Driving home yesterday clutch pedal went to the floor without disengaging. I gave it the usual couple of pumps to try and build pressure but no joy. Jammed it in second gear and nursed it home as you do. First checked fluid no probs. there ,.Master cylinder seems fine... slave cylinder fully extended. I crawled under the vehicle and shoved the linkage back up (seemed a little crunchy).tried clutch again seemed to be working fine so took it for a run.Worked fine for about five minutes then pedal went to floor again. So home again floor panels and gearbox tunnel out .It now seems the tube that connects the clutch linkages together has failed at some point in the dim and distant past and has been "repaired" by welding the slave cylinder end to the shaft and welding the clevis pin in place. I'm thinking that either the tube or the clevis pin at the other(clutch) end has failed and the brief period of working again was caused by me shoving the linkage back up and the damaged parts somehow catching against each other allowing the clutch to work . Some part must still be attached as the tube is refusing to come out and as it is hidden in the bell housing I don't see how to remove it in order to replace it. Has anyone
ever had to remove one of these connecting tubes/clevis pins and if so can you offer any advice.
Thanks for reading
 
If there is no pin through the tube /shaft at the clutch end then the tube should come off,however it seems there has been a bodge job done in the past.Could be the shaft has broken at the hole,the hole has worn large or even the pin went missing and the quickest fix was a spot of weld.Nothing would surprise me.
Cutting off the remnants with a grinder/dremel tool and see what is what.
Oh and welcome to Landyzone Sgt Wilson and don't panic.

Thought about trying to split the tube length ways with a hammer and chisel but that would send a lot of shock force along the shaft and I'm not sure what that might damage plus I would probably still have the remnants of the clevis pin rusted into the shaft with no way of getting in there to punch it out.
 
it does return fairly easy but as I said feels as if something is crunching which I think is the cluch end of the tube rather than something internal but I can't be sure
 
I have... the plan was to remove the the whole thing with the welded part intact to give more access with the grinder or at least pull it out as far as the bracket will allow .
 
I have to get off to bed now as I have a night shift tonight but if you have any ideas please post and i will check them out in the morning.Thanks for you advice so far I'm sure I am not the first person to have this issue
 
Free that bracket and tap shaft for out,if just gripping a bit it may well come, some rotation may also help.Good luck and remember " Put that light out".

Wouldnt worry about correct etiket and stuff. Most of us dont know much about that either! :D

Like he says, reckon just chiselling, grinding and dremelling, get it apart as best you can. Then try and rebodge it, keep it going until you want to take it right apart and do a proper job.

Only other thing I could add, try and remove as much floor, trans tunnel, linkage that you can get apart. Clearance often isnt great on these jobs, and a little better access sometimes makes for less stress, and better quality of the finished job.
 
Update
After much grinding ,chiseling,hammering and skinned knuckles the connecting tube is now removed. As suspected part of the clevis pin remains in the shaft poking out of the clutch bell housing. The back half of the pin (split pin end) came out with the tube.The remnants of the clevis pin remain in the shaft. As I can only get to the head end of this pin I have ground off the head and attempted to drive the pin all the way through the shaft with a punch but it is seized solid. My next plan is to get some heat in there but there is a rubber grommet where the shaft comes out of the bell housing that I cant get out in one piece which is going to get destroyed by heat.Does anyone Know if this grommet can be replaced from outside or if it is not replaced would it cause much problems.
Thanks for any thoughts you may have
Regards
Wilson
 
After several weeks on and off of beating, heating,hammering and swearing I was about was about to admit defeat when one final angry clout with the hammer and punch moved this bloody pin a tiny fraction of an inch. one more tap and the sodding thing just fell out (all half inch of it) The clutch is now sorted and working fine. The offending part of the pin is sitting beside my keyboard and I am eyeing it with a kind of weak loathing as I type this message. I may get it framed and keep it as a small monument to the spirit of mankind...
Thanks to everyone for your ideas.advice and suggestions
Regards
Wilson
