Balancing a RX crankshaft
Hi all,
As recently posted, i rebuilt my RXZ. The engine is currently running a first oversize, no sleeving, with brand new rings, bearings, oil seals. I wanted to get a big rebuild done by atul, but due to financial constraints that idea did not materialize.
The con-rod and roller bearings have been changed, since there was a lot of play in them.
My issue is, during the running in period, the engine vibrations till 4000 rpm are bearable. But after 4000-4500 rpm, it simply starts resonating.. Well over stating, but yeah the vibrations are far too much...
My query is. Is there any way to balance the crank dynamically with the piston attached??? so that the vibrations are minimum???
We have counter balancing shafts and what not, now that cant be implemented in a RX. But what can be done so that the vibrations are manageable???
I would like an insight from the tuners, as well as the regular rebuilders.
So help me out please.
