I was putting new main bearings in my Continental Z134 gas engine (in a Ferguson TO35)and got a little perplexed at the instructions, via the tech manual. The rear main bearing cap is also attached to the rear main seal plate, via two 1/4" bolts. Manual says to remove those two bolts first, which is obvious. But how? I'm wondering what was supposed to happen, as opposed to what I had to do. The bolts that were in there were just standard hex-head bolts and nuts, i.e. nothing to prevent the bolts from turning with the nuts. And, no way to get a wrench on the bolt-heads. So, after some screwing around, I cut them off. Then when reinstalling, I put in new bolts that I cut screwdriver slots into the heads, so I could hold with a right-angle screwdriver. All worked fine, but I'm wondering if something was supposed to be different then what I found in there?
