drooper Posted April 9, 2017 Share Posted April 9, 2017 hi all i have a 1970 13/60 i bought 6 weeks ago to get back on the road after 20 years since its last mot,i have a strange clutch issue that maybe some one out there can help out withafter getting her running the car would not go into gear , i managed to free the stuck clutch but still the same, i had already changed the old clutch slave cylinder which had siezed and had a small 1/4 inch socket inside for a new slave cyl , new clutch master cyl rubbers , new fluid and bled the system , good pressure , still same problem , seems like not enough pedal travel to disengage clutch , (hence the 1/4 inch socket by prev owner) pedal will not go right to the floor , stops about 2 inches from floor but when the slave bleed nipple is opened it goes right down to floor , so its a mechanical issue , checked all poss issues , clevis pin wear , pivot pin , pulled out gearbox checked out thrust bearing/carrier/pivot pin all good pulled off clutch to check its not in back to front all appears ok and in good shape although dont appear to be original , but have hit a brick wall nowlooking at rimmers the clutch cover looks different/thicker than mine (which is 40mm high) can anyone confirm the thickess/height of the standard cover ?i am thinking maybe wrong clutch cover , it is as if the clutch cover needs to be thicker/higher as there is approx 1 1/2 inch free play on the thrust bearing pivot arm before the bearing touches the clutch cover diaphragm and when the slave cyl is fitted it bottoms out on the circlip so not completley disengagingi could put it all back complete with 1/4 inch socket/distance piece as last resort ,but that is not how i do thingsany help greatly appreciated Quote Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 9, 2017 Share Posted April 9, 2017 certainly sounds like the cover is thin/ low fingers or thin throwout bearing, the socket spacer is telling you its been hybrid for a while are there any identifying marks on the cover ?? ,, maybe a photo of the offenderthrow out are common across the range, 1200-13/60 the WSM gives cover dimensions for coil cover but not for diaphragm covers !!! there are many clutch covers available in you dia and fitting but can vary in cover design and finger heights My guess its you have a rogue fittedPete Quote Link to comment Share on other sites More sharing options...

davidb5964 Posted April 10, 2017 Share Posted April 10, 2017 if it has an lc number on it in white paint I may be able to up the finger height for you when it is clamped over the driven plate, ie bolted onto the flywheel assuming the drawings are still in the file if it helps.

glang Posted April 10, 2017 Share Posted April 10, 2017 oh dear that doesnt sound good because if its been run with so much endfloat (which the socket distance piece might indicate) then there can be irrecoverable damage to the block.....

Pete Lewis Posted April 11, 2017 Share Posted April 11, 2017 if the faces are OK, but the wear has removed the lugs on the bearing cap you can with care build some weld to re fettle some retaining lugsif the crank face is damaged there is bigger decisions to make Pete Quote Link to comment Share on other sites More sharing options...
Jonny-Jimbo Posted April 11, 2017 Share Posted April 11, 2017 Quoted from Pete Lewis if the faces are OK, but the wear has removed the lugs on the bearing cap you can with care build some weld to re fettle some retaining lugsPete KD did that on my Herald engine after it dropped the thrust washers on my way to work one day. Worked well right up until I sold the car two+ years later... and the guy that bought it then promptly crashed it... Quote Link to comment Share on other sites More sharing options...
drooper Posted April 11, 2017 Author Share Posted April 11, 2017 all will become clear when sump is off, watch this space!! Quote Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 13, 2017 Share Posted April 13, 2017 got some wear on my 2000 crank, on inspection the rear thrust was fitted wrong way round ,, still pondering over a solution but the crank face is in a bad way , Pete Quote Link to comment Share on other sites More sharing options...
