Prop Centre Bearing - Angle of dangle?
TimC - 26/7/07 at 08:13 AM

'Morning all

My drive-train is 'sans' reverse box so there is just a flexible centre bearing. I'm having some difficulty fitting this without putting what looks like quite a lot of strain (stretch really) on the rubber part of the bearing. Can anyone give me a guide as to what is acceptable?

Thanks

TC

thats exactly like mine! I dont think it wants to have any pressure on either side of the rubber bearing tbh...

Damn.. anybody got any shims?

Hi Tim

What exactly do you mean by putting it under strain? Are you having to twist the bearing so its not perpendicular to the bit of shaft it goes through, or having to pull the bearing away from its natural position along the prop?

As others have said though it should ideally just sit in its natural resting position.

See Paint diagram below. Largely ignore the angle of the prop as I can't recall how it sits. In essence the rubber part is being pulled out at an odd angle. It seems to be a combination of the horizontal and the vertical that is having the effect.

I really don't mean to have a go at the crudity of your paint diagram, it's prob better than I could do - but if thats what you are giving us to go on, it might be an idea to signify where the UJ would be in your setup!

cheers,

Do I look like Michaelangelo???

Fair comment. I'll try to do a more accurate one tonight when I'm actually looking at the thing. Better still I'll take a photo!

no - you look like the guy out of the office, also called Tim!!!

The reason why I said it is because if you look at my photo, you physically couldn't twist my prop in the same manner as yours because of where the UJ is, so I wondered if it was different to mine!!!

Best take a pic mate!

Can't you put a plate in and mount the prop bearing on the side of the tunnel instead of the floor? It would give you more options for changing the angle by using shims or nuts either side of the bearing support. Here's my temporary one to get the angles etc., excuse the rust Rescued attachment proptop.JPG
