I need to pull the flywheel on a 1979 DT65. The puller attaching bolts have a 4-bolt (square) pattern, unlike most flywheels that have a 3 bolt (triangular) pattern. All my pullers are set up for 2-bolt or 3-bolt flywheels. Is it OK to pull the flywheel using two bolts, or do I need to make a 4-bolt puller? Thanks for any advice!
