I screwed them by hand by it wasn't enough.
How can i screw them together and should i apply thread lock?
Should posted on S710 thread but I do not recall having this problem discussed. Just to give some suggestion, first thing to do is to check whether the engine spins in the correct direction (counter clockwise). I`ve seen this happened even it is somehow unbelievable. About the pinion gears, I`m not sure how can they unscrew and block the engine at it can only unscrew forward? No need threadlock and the 2 plastic tools gear should work just fine. Tighten all pinion gears by hand (note the orientation of the second pinion gear), put the tool to hold the second gear and use the other tool to tighten the first gear. Last but not least, be sure the clutchbell (where the pinions mounted) can spin freely after assibled with your engine.
