I am reassembly an older Stihl 025 and I noticed when installing the engine pan back onto the cylinder/crank assembly that there is some slight rocking on the crank bearings that does not let the pan sit flush with the cylinder. It almost seems as if the bearings are not fully seated in the journals of the two halves. I did not move anything or remove the bearings so this has to be the way it was before. The crank bearings obviously would have the be the tightest factor when joining the 2 halves or they would risk spinning in the journals instead of being held in place. Is this little bit of play normal and gets taken up as the engine is torqued to spec in the saw frame? I went ahead and applied sealant and assembled the engine and torqued up to spec in saw and it seems to have pulled the halves together. I was just wondering while waiting for it to set up and vac/press test if anyone else has seen this in a clambshell engine? thanks!
