Just got my LD on the lift to sort out a few issues from summer use...could do with some pointers;

Had an oil leak from Kick start housing, which initially I thought was due to me overfilling the gearbox...however on close inspection it looks like there's oil coming via the lower kick shaft housing..right at the back in the casing where the end of the shaft sits, No seal there ,so is it a crack? Have a look at the pic attachment of the lower kickstart casing hole.

And as a reminder is it about 1/2 pint in the gearbox of SAE30?

The kick starter pinion unit (in the upper hole) is all good and no leak, oil only coming from the lower hole in the casing.

Last one..rear bevel gear, got a oil leak, so took the cap off the end of the drive shaft casing and need to sort the gasket out.
Think this needs SAE140? About 1/4 pint from memory? Cheers

So left the Scoot for a night and it looks like it is the bevel gear housing oil seal after all that is the root-cause of the oil leak... Anyone know the right size for this seal? Looked at all the usual sites to buy one and none available. The joy of a 69yr old scoot.

Rear Axle -------

The rear axle oil seal is available in engine seal kits. Here's one example:

I'm sure other suppliers have them as well. The seal is 22x40x7. You could go to industrial supplier and see if you can find a seal there. Here's one example:

It's has a double lip which improves seal performance.

As to oil type and amount, yes, it is 140 weight gear oil. With the scoot on it's stand, fill until it is level with the fill plug.

Does your engine have a rear axle vent? Good idea to add one if yours is an older engine without one.

Kickstart -------

It is really hard to tell from a photograph if you have a cracked housing. Clean it carefully and bring it to a machine shop if you are still not sure. Depending on the location and depth, you might be able to seal it with Devon Aluminium Putty. Again, this sort of thing is impossible to diagnose over-the-phone.

The tranny takes straight 30, non-detergent motor oil (any lawnmower/small engine shop will have it) or, you can also use GL4 gear oil (better protection for the gears but a little harder to find). Fill until it runs out the level indicator at the bottom of the engine. The level plug is shown here:
