I finally tackled what I thought was a rear main crank seal changeout on my AQ125A. When we pulled the engine loose from the 270 outdrive housing we saw milky oil draining down the outdrive casting. It was seeping between the PDS and what appeared to be an oil seal. I was able to wobble the PDS in the seal. My question is there a bearing just beyond the seal that I saw. Also should the PDS be straight going through the seal or have a little wobble? I have a Clymer V-P shop manual that diagrams the AQ280 unit. It shows the seal and what appears to be a bearing through which the PDS runs. It appears to be just beyond the back u-joint. BTW the rear engine seal was not leaking. But the pilot bearing in the crankshaft for the PDS was in bad condition. All info will be greatly appreciated. Thanks, Marc.
