Removing tach gear

[Northern Mike]

Is there a trick to removing the tach drive gear on a 79 gs750e?
I removed the one screw that holds the clip in in the slot.
The putter ring with the seal in it cam off, but looks like the casting broke flush with the gear still inside.

It's an assembly...the tach gear will need to be "unscrewed" from its meshing gear to come out

Does it look like this? Not sure about the 750 but this worked on an 1100G.



Try clamping a set of locking pliers on the end of the gear and pulling it out. You may have to pry against the pliers. I used a wood block to protect the cooling fins and pried against the engine with a flat bar. Slow steady pressure and it'll pop out.



Then you're left with this. It's maybe 50 bucks for a new sleeve, drive gear and a couple of seals.

If that doesn't work, you could try tapping it out from the inside with a small punch.

Looks like I am pulling the valve cover.... Thought I was not putting too much pressure but apparently city did and broke the steno off the gear.
Is it feasible to reuse the valve cover gasket and am I looking at tons of hate pulling the cover off with the engine still in the bike?

It's a crap shoot on the gasket, depending on how old it is and if any grease was used on install. I have reused gaskets several times with no issues, but that is not always how it goes. If you don't know how old it is and what shape it is in just order a new one and start fresh. Of course you can pull the valve cover off in the frame, how else do you check valve clearances?

Good point on the valve clearance.
This bike keeps kicking my butt. Little things turning into big jobs...

Just pulled and replaced one. I'd skip pulling on the gear itself and tap it out from the inside the cover once removed. I've had 2x fail in 12 months and finally replaced with the new p/n. This gasket (oem, greased) has had about 6-8 removals without leaking/breaking. 30 minute job.

Edit: having said that, I'm probably hosed on next valve cover removal.
