Might anyone have a good source for an Idler Pulley for Poly-V Belt (multi-grooved)?

It needs to be high quality, preferable aluminium with a high quality bearing. If that's not possible a stock one (anyone have a new one kicking around from crate engine?).

One of my other idlers blew up (bearing failure) and want to change the remaining one to make sure I don't have a problem with it.

Thanks very much Lee, that is a very kind offer.

I got the old one off today. I been concentrating on removing the gearbox to do a rear main seal that is weeping ever so slightly (as fellow aviation colleague, you know if it's not 100% right you've got to fix it).

I'm going to take it my machinist to see what he'll charge to make a custom aluminum one up. He did a beautiful job on the other pulley I needed.

I'll look at him doing new aluminum mount as well as the old one is functional rather than pretty and is fairly heavy for what it is.

If I still need a stock one I'll be in touch (mine has 6 grooves).

Ended up getting one made up. It wasn't cheap by a long stretch but it's 1000 times better.

Before

Plastic stock pulley, with a single row ball bearing and a frankly shocking bracket eek (the weld wasn't even complete!). Paul was spot on with that.



After

Machined aluminium pulley, double row ball bearing and a 6082 T6 machined and TIG welded bracket.
