Flywheel R500/1800 vs 1600 K

[GPBox]

will a lightweight flywheel from an R500 (I assume are 1800) fit a 1600K ?....or have I bought a nice paper weight ?...cheers

All the Caterham K Series installs use a 1.6 size flywheel regardless of engine size so it should be fine for size. Does the pattern of "missing teeth" on the crank sensor trigger ring match what you have at the moment?

IIRC only the 1400 flywheels had a different trigger pattern

thanks for comments....good to hear....will check on crank sensor !...cheers

If I may slightly divert this thread - if you fit a lightweight flywheel one end of the crank . . . anyone worry about the heavy, I assume for a reason, mass on the other end with dual duty as a pulley?

ie any worry about potential mass mis-match of mass damping with the new flywheel?

From what I've heard, DVA fits plenty of light weight flywheels but won't entertain fitting an alloy pulley at the front. But it's certainly an interesting question. I wonder if anyone has done the analysis properly? Mind you, K Series with lightened flywheels aren't generally going around fracturing cranks ... are they?

[Wrightpayne]

The front pulley is usually two bits of metal joined together with rubber. This takes vibrations our of the crank that can cause fractures.
