I did repower two Athearn H0 CF7 with A-Line repower kits today.
The result is not as good as expected. The motor runs ok but the noise is still a problem. I have two observations:
1. The flywheels are glued on the shaft. There is a good fit but it is not balanced. The entire assembly is vibrating. It gets worse on higher speed.
2. The motor is glued to the mount cradle that is glued to the engine frame. There are no rubber shock absorbers anymore.
I'm under the impression that the advantage of the better motor is eaten up by the unbalanced motor assemble and the fixed mount of the motor to the frame.
I would be glad to hear your opinion and some tips how you handle A-Line repower kits in Athearn engines.
