Trying to slide the gearbox into the housing on an MK9. Stops about an inch short. After an hour or so of frustration I take the Layshaft out thinking the reverse idler won’t seat right. I leave reverse on the shaft and try to slide it in. Problem is the Layshaft doesn’t want to slide through the needle bearing. It goes in just far enough to engage the coupler and then just stops. A lite tap with a rubber mallet and it goes in a hair but then it’s hell to get out. Both the race on the shaft and needle bearing appear to be fine. I had it together when I mocked up the car originally. Now that it’s for real it’s a no go. I thought about polishing up the shaft a bit in the lathe but figured I’d ask the collective first. I don’t see how I could have misalignment with the input shat or the coupler. Thanks.
