Dismantling Engine and Gearbox removal Due to Big End failure. When I drained the oil, I found that it had emulsified and looked like milky coffee, maybe water had got in, or condensation?

Quite possibly, I can't remember if the gearbox has a breather hole or not, maybe drill a small one in the cover plate marked 5 speed? Also watch out for thin end cover gaskets, usually the green ones, they can cause the kickstart to bind, if so you will need two of them.

While you have the engine apart check the state of the oil pump bodies, i.e. the timing cover, smaller chunks of abrasive debris from the failed big-end can pass through the strainer plug and score-up the insides. Good opportunity to fit a serious sump magnet.

Thanks Adrian
This afternoon, i am going to scrape off the old gearbox gasket, flush out the emulsified oil, clean up the corrosion, lightly reassemble side cover. then clean and store.

Would the red gasket be original?

Might even start disassembly of the engine, drain oil, remove cylinder head.

Thanks again for the Advice.

Long answer, yes.

Might be worth taking a few photos as you strip the engine, just to see how much or how little damage has been done elsewhere. What were your plans for the crankshaft repair?

Hi
I have just carried out exactly the same on my 2006 Electra, I also had a gearbox full of emulsified oil traced mine to water running down the clutch cable into the gearbox I did a complete gearbox strip as a precautionary measure and found a corroded main shaft and timing side bearing. I used Henry Price to rebuild my crank assy and simply bearings for the bearings and seals for both gearbox and engine.
