I need to shim mine a bit after 50 hours... is it acceptable to insert a U- or perhaps better described as a C-shaped shim, or is it necessary to pull the bolt to insert a full-circle shim? I don't relish removing and realigning those bolts although I've done it before to hang the engine.
I can't easily envision cheater C-shim coming out but they'd alter the bolt torque if they managed to work out from under.
