G260 Output Shaft Flange Lock Tabs

[LateFan]

Reading up in the Bentley on changing all the seals before swapping a manual trans in ('86 ES).

On the rear output flange nut, I'm not seeing any lock tabs or lock washer. I buzzed it briefly with an impact and deep socket, no budge. You can see in the blowups it's rounding the nut a bit. You can see some scratch marks where I poked around with a small screwdriver in those recesses. Am I missing something?

I also read about the sealant - maybe I need to heat the flange and nut before trying again?

Hard to tell but the lock washer gets hammered or pressed over and around the nut. The washer is probably what's causing you to round the nut. You need to pry the washer out using the recesses (It can be a pain) and then hit the nut with an impact. IIRC, it's the same principle as the rear wheel bearings.

Oh...now you've got me wondering about pic #2 and instead of a rounded nut, that's the folded plate of a lock washer against the nut.....

Nope, there was no lock tab washer. Someone must have put a new seal in and trashed the washer and didn't replace it.

I used some heat on the nut and the output flange, used the impact gun, rattled a while, popped off. Output flange came right out - no puller needed.

Just need to decide if I can clean up the nut with a file or just get new.

Just curious: how do you install the lock washer so it stays on snug? I butchered one pretty badly.

With something flat and sharpish peen the outer rim in place at both sides of any recess around the perimeter of the area. It helps if you keep the socket in place to prevent the washer from jumping out of position when you hit it. Also not a bad idea to buy an extra (same for the axle nut washers) when you are doing a job like that in case you distort it on the first try.
