Gear Box Outer Cover
« on: July 04, 2019, 03:06:24 PM »
I'm trying to track down why I'm getting 0 volts at the oil pressure warning light.
I suspect that the oil pressure switch has failed.
My limited knowledge of these bikes tells me that the switch is located at the back of the crankcase on the left side.
As such, I'm trying to remove the outer gear box cover, but it goes only so far:

I can get my finger tips in between the cover and the crankcase, but the wretched cover won't budge any further.
How do I remove this cover without resorting to brute force and ignorance?

BTW, a fair amount of oil came out, which I wasn't expecting.

The oil pressure switch is under this rubber cover, which is on the right of the engine.

Doh!
Thanks for the info - I'll just button up the gear box outer cover.
(If there were a red-faced icon, I'd use it.)

Don't forget to check your oil level when you have buttoned it all up 👍👍👍👍

New oil pressure switch arrived today, fitted it, and... oil light now comes on - hurrah.
Now let's hope it goes out again when I fire her up.
I'll add some more oil to the tank at the same time, Julie - not too bad running low oil on a dry-sumper, though.

I don't like anything running low on oil, wet sump or dry sump.....its unnatural 😁😁😁

When you tighten up the mission cover, make sure that you have not trapped any wire that run in the channel at the back of that cover.
Strange to see a early head on a K3  ;) ;)

What's a "mission cover"? (My ignorance of these machines is shining through.)
How can you tell it's an early head?
If it is an early head, it's probably not too surprising, given the bike's 46 year age.

Mission cover ( transmission / gear box cover)

Early head ( 1969 to 1972 )  ;)

I can tell its a early K0 to K2 by the fins.
