clutch engagement

[Kurt Henzler]

where does your clutch engage on your 06 g56. i test drove one on the lot and it was right off the floor. mine is almost at the very end. you only have to push it in 3 inches to disengage. is it related at all to clutch wear?

Clutch engagement is related to clutch wear (I think engagement moves closer to the floor as you wear the clutch out... someone correct me if I'm wrong). But more importantly, the clutch on a G56 and an NV5600 are worlds apart. My NV5600 is like yours (3" to disengage). Has been since brand new.



If you're wondering whether your clutch is gone, don't. Your description sounds normal to me.

thanks for the reply. wonder why two different same model trucks have such different engagement. can this be adjusted?

i was told the cutch on the g56 will engage closer to the floor because of the DM flywheel. is it holding good?

The plate load of a diaphram clutch is a bell curve... . that is... . your on the right side of the curve when the pressure plate is new... and as the disc wears the load increases to a point and than starts to fall off with more wear... once you get to a point of worn disc and the plate load has fallen off..... the clutch will start to slip and shes all done.....



As the disc wears..... the pressure plate moves towards the flywheel... remember that the the disc is thinner... . as this happens the fingers on the diaphram move towards the transmission..... thus closer to the release bearing..... so as the disc wears the release point on the pedal moves towards the top of the stroke... .



This is all relevant... if the same part number of cover is used from one truck to another... . the location of the release point with the new disc. . of the same thickness should be the same spot..... However understand that mill run thickness of the friction and steel used in the disc might make one disc . 030" thicker or thinner than the next disc... .



The last point is that there is no adjustment on the clutch unless you change the length of the rod... . which will change the release point on the pedal... . Oh, other things will effect this... air in the system. . worn ends on the rod... work pivot etc... . but if all things are equal and right there should be little or no change...



Hope this helps..... this is the short version... . I have a 300 page book on the design of diaphram covers by a very good engineer... ...
