[QUOTE="BigEd, post: 55358, member: 161"] The plate clutch is the servo as this is a light clutch that engages the main clutch by pushing the shoes onto the drum. If I correctly understand what you are saying you are on the right track. In relation to the C7 shoe plunger, if your friend had the thimble screwed right in then the pressure was too great for the primary clutch to overcome so the shoe was not forced hard into the drum. As you said, when he backed off the thimble and thus the pressure, the primary was then able to apply sufficient pressure to the shoe. In an instance as described the C7 pressure can be backed off a little at a time until the main clutch grips. If you slack it off too far it will start to grab. It is not an easy thing to get your head around until you study all the bits. Read "5" again in my previous post. [/QUOTE]
