Thanks. Really helpful. I also found a few other threads on here that helped.
I got the motor out. It wasnt too hard. 3 screws, which were stiff and a bit awkward to reach. (Although removing 14 year old screws is much nicer in the cabin than underneath :))
The motor will run if I give it a push start, but not for long. It squeaks and it wobbles slightly as runs and then stops. Any clues?
Get the feeling it is just done for and I need to get a replacement. I have tried to lubricate what I can see, but no improvement.
Is it possible to strip down the motor further? e.g. remove the fan blade assembly?
