911 SC instruments & gear knob


Recommended Posts

Hi folks,

Great forum - can’t believe it’s taken me so long to find it! I’ve owned an ‘81 sc backdate for over 10 years :0

Can anyone tell me the inside diameter of an SC gear knob (915 gearbox) or the outer diameter of the top of the gear stick?

Also, does anyone have a speedo for sale - my speedo works fine but doesn’t record miles?
Alternatively, is there someone who repairs them?

Many thanks

Adam

15mm OD for you gear lever. 

The gears for the odometer may be stripped or just worn. I replaced mine on my last SC, it was a bit fiddly but do-able. I'll try to remember where I bought the parts.

Ah, that’s great - was it quite straight forward to see which cog was worn / broken?

Yes, it's the one that looks the same as your new one but has teeth missing😁

Sorry, couldn't resist. It will be obvious. 

There's you tube videos walking you through it. I managed it and I've got fingers like a cows tits!! 

Just take your time and don't damage the needle. Very rewarding and you get to retain the original speedo.
