I don't think swapping to a w56 would solve anything. My G52 is in good condition and will be strong enough for a DD. The problem I'm having is nothing related to the G52 in specific. The W56-A uses the same release bearing,clutch fork, and bellhousing as the G52/54. The pilot that the release bearing rides on is the same diameter on the G52 and W56 series. If I swapped in a W56-A I would still have the same issue. The I.D. of the W59 release bearing that rides on the tranny pilot is .020" bigger than the older models. The W59 bearing is a little longer from the part that contacts the fork to the end of the bearing. This should make the slave have enough travel to release the clutch. Whereas the older model bearing is shorter and the slave is running out of travel at the same time the bearing contacts the pressure plate.
My question is, is everyone using the W59 release bearing even though it's a sloppy fit on the tranny? Does it even matter? Has anyone else noticed this? Just want to be sure before I bolt the motor back up.
