ring gear marking compound

[john h]

Hi all,
just got my Diff back form the drive line shop.  I'm wondering if I should wipe down the marking compound before I install the diff?  would that compound possibly cause any lube issues or ring gear issues in the future if left on? 

Thanks
John

If what you are referring to is the "bluing" that is used to check gear mesh then there should be no problem. If the material is a gear "lapping" type compound then it must go.

its a yellow compound for checking The pattern.  its on about 5-6 tooth patterns in a bunch and in about 5 spots around the ring.

If it makes you feel better, clean it off...but it will not hurt anything at all.
