i’ve got a tacx flux s (T2900) and have bought a new freehub body for it. the old edco body (shimano/campy combi) was noisy, and i was getting skips and poor shifting. i’m running shimano 10-speed.
how the hell do i mount it? i’ve removed the old one fine. and can fit the new one onto the axle body, but can’t get it flush - the pawls don’t seem to want to engage. what am i missing here?
Possibly some cleaning/greasing would have fixed the old one; greasing might be required on the new one also, by the way: is it compatible with the hub axle and shell?
Tacx support and youtube videos would likely help

Not flush where? As in the pawls are extended keeping the body from sliding into the hub? To fix that, you can wrap some thread or dental floss around the pawls to keep them compressed, slide the body in most of the way into the hub and then pull the thread out.

excellent - yes, the pawls are extended and i think that’s what’s stopping it pushing into position.
but then i’m thinking it can’t be this hard, and doesn’t seem to be in the videos i’ve seen . . .
still no luck. i’m wondering if there are some burrs on the threads at the end of the axle or something - even removing the freehub once i slide it on is really tricky, and once it’s slid on past the threads it still won’t engage. i can’t tell if that failure to engage is actually because of the pawls or some other blockage.
i know it’s not supposed to be this difficult, so something’s up.
Long shot, but did you remove the original black sleeve from the axle when you took the freehub body off? The new freehub has (from memory) a new sleeve already inserted, it would foul up against the original if you left it on and stop you sliding up unto place.

Cheers, Rich.
it’s a good call - i did recognize that the black sleeve could be a spoiler but no - it’s not stuck in there. you remember right that the new freehub also came with the sleeve inserted, and i decided to chuck the old one and stick with the new one, assuming it’d be cleaner/in better shape/etc.
Should go right on once you flatten the pawls. I just replaced the same one about a month ago. Slid right on.
that’s reassuring. did you use the thread/dental floss trick? i guess i’ll get back to trying again. it’s hard to find the time with two little kids tearing around, but with winter coming on the clock is really ticking every minute the trainer’s not built!
a combination of elbow grease, actual grease, and the dental floss trick. i think that there was a seam/joint on the inside of the body that was getting stuck on the axle - it was hard to put on but also really tough to pull off, so something was clearly ‘sticking.’ maybe just a result of some slightly sloppy machining or maybe it’s my trainer itself that’s getting a bit old and tired.
but my wife just did a ride and it was a great improvement - quieter and better shifting.
