Jim;

I had to replace all of the motors in my '06 Magna after the fire at Premier RV in Junction City. They have the info about where they got them and what the costs were. Don't know where you are, but if you're anywhere near central Oregon, they could help you. Otherwise a call to Jim Cooley, service manager, might get you the info you need. I think mine were repacked rather than rebuilt. Phone is 541-998-2640.

You can only use it for a test. I mount it temporarily ( to not to get caught in the belt) and do a test at cold and then hot conditions. Should be 800 RPM when cold and 2200 RPM when hot.

OK, I've read the entire thread and I'm curious. Where do I put the reflective tape on the fan? Wouldn't the fan speed be higher at the perimeter than at it's axis? I'll get a the radar test gun and try mine. We just installed the Source Eng. wax valve...and the OTR A/C is mildly cool at best. I'm hoping there is not a correlation!

THanks,

I just put mine on edge near outside diameter of fan. It is measuring RPM so it doesn't matter where you put it along fan blade. Just make it easily seen by the photo cell in tach. And don't get wrapped up in belt! Be very careful. Temporary mounting of the tach is a good idea.

Let us know what your tests show. Again mine was 800 RPM cold and 2200 RPM hot. The challenge is to get it hot without climbing a big grade at 55-60 mph!

usually the tach instructions will tell you where to place the reflective film
It is not unusual for these motors to reflect a slower speed when there is the slightest amount of dirt in the motor or fluid. The motors have very sensitive shims in them. I have not found anybody confident who can clean them and rebuild them here in the US. Colton truck took mine apart and lost half the shims. I replaced the motor but it took 3 months to get it and very expensive.
