I've changed the rear gearbox mount for a new one (thanks MrF) and I've changed the centre support bearing for a nearly new one (thanks Slick Pete) but I'm afraid to report that the vibrations are still there. It's a coarse-ness that comes in about 40 and goes about 70.

 

So - a couple of questions:

 

The UV joints on the prop are all tight but very notchy. Is this the fault or are they supposed to be like that?

 

There is the possibility that I've reassembled it out of balance. I marked all of the joints as you are supposed to but removed the centre flange without referencing it to the front shaft - so I guessed it position on reassembly (what an idiot!). So, can I simply rotate the centre joint through 90 degrees and hope that the 2 shafts reach equilibrium, or am I stuffed...

 

...any thoughts would be welcome.

 

many thanks

YOu aint got it back on straight i'd say is the prob :( take off and start again :( brave buying a used bearing though :x:

Did you ensure the thick washer /spacers on the bearing support bracket are between the body and the bracket rather than under the head of the bolts?

 

Common mistake is to get these in wrong place or even have them missing, causes the prop to be out of line.

Chris - bearing was one week old - it certainly looked new and was tighter than the one I removed.

 

Jeff - nail on the head as usual - I have put the washers/spacers between the bolt heads and the carrier. ...many thanks for the info.
