rbrtcrowther Posted January 14, 2009 Share Posted January 14, 2009 Hi there Popped my clutch of last night and my thrust bearing is a perfect fit on the tube bit. My scammell is a 1950 first contract (I think its the 83rd one built) so perhaps the design changed? Don't suppose you could put a picture of where your axle oil cooler pipes connect to your engine as some silly sod disconnected mine cos the cooler froze up and popped apart. Rob.

Rob. u have got me worrying now rob :shake: mine is a loose fit on the tube but saying that is been like it since the diesel went in and its seems to have been fine. it works fine now, also u knowing more about clutches than me should i be worried ? mine is also an early one how early i dont yet know as the plate has been painted over but has the early civy dash . these pics arnt brilliant will get better ones on sunday weather permiting .

rbrtcrowther Posted January 14, 2009 Share Posted January 14, 2009 Cheers for the pics. The plumbing on mine is shocking with pipes blanked off and random household fittings so don't be shy with the camera every picture can help someone. I have put some pics of my clutch on my blog but none of the thrust bearing. i will try to get some up soon. When i saw the thrust bearing on the tube i thought it was siezed, it was tight. when i slackened the pressure plate (without using the packing shims) the bearing slid down the tube and scraped a load of goo as it went. the military may have changed the design due to problems. It says in the book not to refit main bearing dowls in the engine, so thigs get modifyed all the time If it works fine and makes no nasty noises i shouldent worry. You only press it to start and stop. I'll have a goo look tomorrow and get some pics. Quote Link to comment Share on other sites More sharing options...
N.O.S. Posted January 15, 2009 Share Posted January 15, 2009 There is nothing in the repair manuals about checking clearance in the shaft/housing, and there is no replaceable bush. On this basis I don't suppose they were ever any problem (I believe the Matador clutch has a non-metallic bush but again no reference to wear checks in the manual). The Scammell has a greaser to prevent this housing from seizing on the shaft. The whole assembly is held in place by retainers on the end of the clutch operating levers. It is designed to be a nice running fit to hold everything in place and in alignment - should a lever retainer come adfrift then with all that play it might run out of true and cause vibration?? If it works fine, I don't see it as a problem. Quote Link to comment Share on other sites More sharing options...
rbrtcrowther Posted January 15, 2009 Share Posted January 15, 2009 Hi Have been and took some pictures so here they are. If you could put your pictures up again and we can play spot the difference. Quote Link to comment Share on other sites More sharing options...
N.O.S. Posted January 15, 2009 Share Posted January 15, 2009 That's had a lot of grease!!!!! The housing has a seal at the clutch plate end and none at the rear - so that excess grease from the release bearing can escape at the rear onto the shaft to keep it lubricated. (I think - perhaps I'd better go and check again...might be talking scribble again) Quote Link to comment Share on other sites More sharing options...
rbrtcrowther Posted January 15, 2009 Share Posted January 15, 2009 The last pic shows the tube that the thrust bearing sits on. The output shaft sits in the spigot bearing one end and is supported with the bell housing bearing the other. So no contact between shaft and tube no lube needed. The tube is part of the clutch cover so spinns all the time, the fingers of the clutch cover also spin. so should only touch the bearing face in the same 4 places. I have'nt removed the thrust bearing (don't think i will bother as it works fine). I will also go and consult the explorer bible now.:readbook: Quote Link to comment Share on other sites More sharing options...
N.O.S. Posted January 15, 2009 Share Posted January 15, 2009 Sorry Rob, I thought that was the bore of the release bearing housing, but I can now see it is the tube, and that the housing is a nice fit on it. I checked the clutch drawing and the seal / lubrication arrangement is as I thought. Quote Link to comment Share on other sites More sharing options...
rbrtcrowther Posted January 15, 2009 Share Posted January 15, 2009 So have we figured out why younguns thrust bearing is baggy?:??? Quote Link to comment Share on other sites More sharing options...
younggun Posted January 15, 2009 Author Share Posted January 15, 2009 (edited) thanks for those pics rob confirming that my bearing has some play on the tube . there is only about 3-4mm of play on the tube but this is enough to worry me:shake: . i dont seem to be a sleav of something missing according to robs pics . so y is this ? or am i simply victim to someone elses bodge ? i dont want to have to take the clutch out again if i can help it :cry: Edited January 16, 2009 by younggun Quote Link to comment Share on other sites More sharing options...
rbrtcrowther Posted January 16, 2009 Share Posted January 16, 2009 Lets not rule out the possability that my clutch has heen modifyed. It looks like there is a bronze bush between tube and bearing outer. Also we have only seen two clutches and could really do with seeing another one:undecided: ther must be someone who has a clutch out there we can look at.:-\ Also if you can take the inspection covers off the bell housing and get someone to press the clutch pedal while you shine a torch and look at the thrust bearing. Make sure it dosen't shimmy or flap about when depressed (or released or any other position for that matter) Try at various throttle settings too. Make sure it's square to the cover plate. If it all looks ok I shoulden't worry it may have been that way for years! Was the bearing baggy when you took the clutch out? or have the clutch people made an arse of it.:??? Let me know how you get on. And if there is a problem don't panic it's only time effort. Sleeve the bearing or fit a new tube. true it up on a lathe. Post a message on the explorer thread someone must have a clutch cover somewhere! Quote Link to comment Share on other sites More sharing options...
thor698 Posted January 16, 2009 Share Posted January 16, 2009 Regarding youngguns clutch I have a double plated clutch in mine - when I fitted it, I did not worry about the tube for the thrust bearing. So a little bit of play between the thrust bearing and tube shouldn't be any trouble. Mine has been without the tube for eight years and other than rivet wear due to an old clutch I have had not problems with the thrust bearing. :-\ :tup:: Quote Link to comment Share on other sites More sharing options...
younggun Posted January 16, 2009 Author Share Posted January 16, 2009 (edited) thanks rob and thor i was just a little unsure about it at the time i re fited it i had nothing to compare it too so i just put it all back as i found it . when i got all the clutch back in i checked that the bearing was running out .ther is no vibration through the clutch pedal at all and all in the houseing seems to be square to the face . but i shall keep an eye on it just in case nick Edited January 18, 2009 by younggun Quote Link to comment Share on other sites More sharing options...
antarmike Posted January 17, 2009 Share Posted January 17, 2009 (edited) I have just picked up the Scammell bell housing for a Constructor Rolls C6 but it doen't work the same way.. The clutch release bearing is sitting on a tube on the bell housing. The clearance is I judge 10 to 15 Thou" Edited January 17, 2009 by antarmike Quote Link to comment Share on other sites More sharing options...
antarmike Posted January 17, 2009 Share Posted January 17, 2009 (edited) That is far more like the Rolls C6T clutch on my Antar, were the Thrust release bearing is carried on a turret bolted to the Clutch cover. I estimate the clearance to be 1 to 1.5 thou" Edited January 17, 2009 by antarmike Quote Link to comment Share on other sites More sharing options...
