Gear Marking Compound

[Mad Mart]

Does anyone know where I can get some gear marking compound, the yellow stuff like this...





I can find it across the pond but can't find anything in the UK, except for engineer's blue which I already have but it's difficult to see the contact patch on differentials.

Would this be any use.

Mart at work we use "white lead paste" tin has no markings other than skull and crossbones as expected. This leaves a nice pattern on the teeth for checking pinion depth and backlash. Not something I can grab hold of unfortunately.
Another thing Ive used before is "ocra" or ocre which is a super fine poweder than leaves a print too.

I have no idea why that stuff seems impossible to find in the uk. It's just a yellow pigment (iron hydroxide) in grease. You could just make your own if you don't want to wait the week or so for a tube to turn up from the states.

I've just used blue though on the couple of diffs I've done though I can see a brighter colour could be a bit easier to see.

I'd be tempted to try something like this http://www.craftcompany.co.uk/sugarflai ... i-25g.html

There Rolls Royce boys at my work use Dykem red for checking the gearbox on our turbines.

Never tried it on a diff mesh but I'd give copaslip a go first in the basis that you are bound to have some...
