Main shaft play

[gtrsteele]

I have a T Rex 600 EFL pro and I have some play in the main shaft. The manual shows two different washer sizes. Has anybody here found a washer combination or one size that fits the best to remove the play?

How much play are we talking and where .. above or below top main bearing?


Mine is stock built 600EFL v1 and pretty much went together as per manual without extra "washers". Is something worn?

If this is a new/rebuild are your bearing blocks are in the correct way...pretty sure with out looking at mine ..they dont all go the same way "up"...

It's not a new build. I've replaced the main shaft, the bearing block and it's bearings just recently. So it's like new. The manually shows 2 different size washers you could use. I have one in there now, but I'm not sure of the size and there's a tiny but of play

I have a thin shim on mine, there is still a small amount of play but it is so small I cant get a shim to fit it

That's exactly my problem.

I never worried about it since it was so small, my old efl was the same.

It was snug during the build then 30 or so flights later I noticed the play.

I worry about it. It took a year to do, but I had to replace the bearing in the upper block. It was completely shot. I need to find another shim that's about .2mm thicker.
