My problem involves mating an upper and lower gearcase on a volvo sx-m drive we recently split and sent away for rebuilding/replacement. The rebuilders sent us back a new lower. When tightenting the case together, I've exceeded the torque spec but cannot eliminate a gap between the bolts. It's the O ring over the driveshaft bearing retainer that's holding it apart. I've lubed it thoroughly and replaced it with a new (sierra) o ring but still have a gap. Is this acceptable? I'm assuming water will get in there and split it come winter. Some of our service manuals seem to show a shoulder on the lower for the o ring to sit in. I've got a flush lower with a slight camber in the upper.. I pulled this apart a few weeks ago and did not recieve the original back, fixed a few boats in the meanwhile so can't really remember exactly what my original lower looked like. Any help would be appreciated
