gearbox oil question

[SeagullGuyUSA]

Can I use SAE 140 Hypoid gear oil in the gearbox of a 40+?

I will most likely be using this : http://napaonline.com/Search/Detail.asp ... 006410049#

Most likely..........if it is a single weight oil; even if it has additives. ( I gave up checking when the link asked for a zip code....)

Much quicker to answer this question from the FAQ info here.....

Have a look at the FAQ page on the main site here:

This has all the info and more on these types of questions.

Hypoid oils contain EP additives to prevent the wear that would otherwise occur with hypoid gears due to sliding between the load bearing faces.

As it says in the FAQs EP additives can cause corrosion of bronze components at elevated temperatures. Seagull gearboxes do not run at elevated temperatures!
