BW40 selector nut removal

[waderobertson 111]

Trying to replace leaking selector seal, how do I get the bloody nut off? Think I read a post way back that said the nut requires a special tool or a simple hack I'm unaware of?

 

Cheers.

i thought it just came undone (lefty loosey) and the shifter rod came off?

The BW40 selector shaft seal, is same as the BTR 4speed.

 

It's just a small lock nut, with a flat washer behind it.

The shift lever is held in position, via the selector shaft having two flat sides.

Just trying to get this nut off... might be threaded because its turning but going nowhere.

thats a weird one it should just unscrew or try and get a tiny like 8mm bike spanner the real thin ones behind it cause i think the shaft is half flat half thread.

bugger, should just unscrew in the normal direction, looks crimped over like a lock nut which i don't remember it looking like that (might be the wrong nut sent home cross threaded?)

Split the nut to find the middle 1/3 of the thread on the selector shaft is munched... hence the spinning and going nowhere! Fuck it all. Will try and clean it up a bit with thread file and bang a couple lock washers on there. Just dropped the engine and trans back in yesterday so really don't want to replace the shaft.

looks to be some decent thread there still if you can stack a couple of good washers on the outside of the selector arm and then fit a new nut where the ok threads are.

I find this interesting as I have to do the same thing when doing my t bar conversion

Yup that's exactly what I've done mate, a dab of locktite just for good measure. Got a good tighten on the thread, to the point when I nip it up the gear will shift. I ended up with 3 spring washers and the nut just flush with end of the thread.

That's the stock locknut, they're crimped on the end.

Overtightened in the past maybe? (apprentice mechanic ugga-dugga's)
