Mjit Posted October 25, 2015 Report Share Posted October 25, 2015 So after a faultless summer I take the Spit. away to north wales for a week and...something's up with the clutch! When I press the clutch pedal it will either feel normal or I could get lots of slack and the bite point anywhere between normal and the floor. The general trend seems to be a normal pedal when downshifting after driving, coming up to a roundabout for example. Shuffling forward in a queue or pulling away is when it seems to be lower. The fluid level isn't going down so I'm guessing the piston's sticking in the master cylinder, but only just so the vibration of driving at any speed is enough to shake it free. What do you guys think? Agree with my diagnosis or anything else it could be/I can test for. Thanks Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 25, 2015 Report Share Posted October 25, 2015 could be slave , they corrode and stick more than the M cylinder, both are possibles also a prime thing to affect the throwout is the loss or lossing the pivot pin which is a sloppy fit in the clutch hsg, held in with a crinkle bush called a tolerance ring these fall out and the pin drops its just visible from the O/s of the hsg . you can see the small hole the pin fits in if you look down the off side .

Mjit Posted November 12, 2015 Author Report Share Posted November 12, 2015 Meh! Turns out it wasn't any of the above, it was the crank moving and eating both it's self and the block having dropped its thrust washers in to the sump Link to comment Share on other sites More sharing options...
dougbgt6 Posted November 12, 2015 Report Share Posted November 12, 2015 Ouch! I had massive end float, needed a regrind and a re-bore. Re-bore was because the crank was swinging the con rods forward and aft and the pistons had worn the bores into an elongated S shape. Hope this hasn't happened to you. Let us know what you're gonna do. Good luck! Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 12, 2015 Report Share Posted November 12, 2015 And if its at 8ts worst and the crank has minced the thrust retaining lugs off the main bearing cap you can with care build up weld and fettle new ones just dont encroach into the bearing bore surface done this on a couple of 1300s and its worked for many years , this needs carefull welding skills. Otherwise you can be told the block is now scrap lets hope its not got that bad pete Link to comment Share on other sites More sharing options...
Mjit Posted November 13, 2015 Author Report Share Posted November 13, 2015 Let's put it this way - new (outright purchase) short engine ordered from canley's on Wed... And at just under £500 for a recon block, crank, pistons and rods not bad value! Link to comment Share on other sites More sharing options...
