How much is too much of a groove?

[Groomerdriver]

The primary sheaves on my 05 Vector have grooves worn into them. The sled has just under 8000 miles on it.

My questions is how much is too much? How deep can they be? One would measure the depths with a straightedge laid on the sheave right?

I do not have access to a lathe to sand & polish the grooves out.

Thanks in advance for your comments!

if its still working alright I wouldn't worry a whole lot as long as the bushings and such are good shape.

Have to use some good judgement on this. If the thing is grooved too deeply, then the sheave may be weakened. It is very bad if it explodes.
