Fecon - Eagle Claw teeth?

[kjravn]

Swapped out Fecon double carbite teeth with a set of eagle claw teeth. There now is a noticable increase in vibration. There is a 1 lbs. differance in tool weight. Any advice?

I would have thought , putting on a full set would have had no effect . But it may now need 1lb of steel stock welded to the counterweights on the rotor . Maybe a 1/2lb on each end , the correct way though would be to have the rotor re-balanced .

Are you sure all the new teeth weight the same? You might need to ask someone who works at on on fecons how they are balanced. They may use a heavy tooth because it helps fine balancing. Balancing itself is a fine art on these units.

We have changed out several sets. The only problem was the teeth were (shorter) exposing the back mounts.

Talked to fecon about balancing the drum they were helpful - did some shade tree dynamic balancing ended up welding on about a 1/2 lbs. weight to the left side which removed the excess vibration. All in all happy with the chipper teeth performance on the ASV PT 100 forestry

Could you give more detail in the balancing you did???
