I was out with my brother and a friend thursday after work for a quick ride chasing the remaining light and we got about 15 min out in the backcountry before it happened. We just arrived at a small lake when we opened up the throttles. I got up to around 90 Km/h when the rpm suddenly dropped and a missound from the engine in form of metal scrithcing started. I immediatly pulled the brake and blocked the track and hit the killswitch, to minimize damages. I started checking from an end, pulled the startrope to see if the engine would turn smoothly. Initially the engine turned, but with a sound of metal rubbing against metal. It would then lock up pretty hard, actually so hard that I pulled the entire sled, when I tried pulling the startrope again. First I thought the engine wasn't getting oil and had blown a cylinder ring, but the oil tank was pretty much full. So I removed the spark plugs and poured a little oil in each cylinder to make sure that there was oil there. With the spark plugs still removed, I then started to turn on the primary to see how smooth the engineparts were running. The metal to metal sound was still there and when I kept turning on the primary, the engine would at some point lock up and stop turning. And the sound came from somewhere near the bottom of the engine, on the magside. So I got the feeling that it was a bearing that was blown, somewhere in the bottom of the engine. We concluded that we couldn't do anything else but to get the sled home, so my brother went off and got some heavy duty rope and we got the sled pulled home.
Now, I've worked some hours on engines in general, but I have never pulled an engine apart on my own. I would like to fix the sled myself, but I'm figuring that I can't do it without help. I have the facilities and pretty much all the tools to pull the engine apart. But first I would like to hear if anybody has any suggestions to my problem and might be able to help me and guide me through some parts of the process of pulling an enginge apart. Any inputs are greatly appreciated.
