Jim Jans Posted September 12 Report Share Posted September 12 To make room when I install the ’92 KA 2.4 motor in my MG I need to remove the harmonic balancer pully (3rd pully) is that wise? Will the motor be affected by the lack of not using that outer pully with the harmonic balancer. I only need the middle pully for the water pump and alternator. Thank you Jim '58 ZB Magnette 1 Quote Link to comment
datzenmike Posted September 12 Report Share Posted September 12 I think as the displacement gets up there it's needed to dampen torsional vibrations. You won't feel them but the crankshaft will. If running a belt driven alternator and water pump these will absorb as well. The flywheel or torque converter will also absorb. Probably can run without if at reasonable rev ranges. 1 Quote Link to comment
Stoffregen Motorsports Posted September 12 Report Share Posted September 12 I believe he is talking about leaving the harmonic balancer and removing just the outermost pulley groove. I can't remember if it is a bolted on pulley or if it's cast into the balancer. Either way, as long as the balancer portion is intact, the pulley is superfluous. Quote Link to comment
datzenmike Posted September 12 Report Share Posted September 12 Yup, maybe trim the pulley on a lathe. Quote Link to comment
Jim Jans Posted September 13 Author Report Share Posted September 13 I guess I could investigate cutting the 3rd pulley off on a lathe and just install the harmonic balancer. I'll check it out in the morning and see what can be done. Thank you. Jim Quote Link to comment
datzenmike Posted September 13 Report Share Posted September 13 It's there for a Nissan reason. Not on the smaller L series engines so perhaps displacement dictates it's use. Some larger engines have balance shafts. Quote Link to comment
