Floating axle shaft flange sealant


acem

Recommended Posts

The rear axle bearings on my 74 loadstar were originally packed with grease and had a sealing ring thing on the outer axle nut. The seal has been removed and the bearings now run in oil. The axle shaft had some type of sealant when I removed it but it is so thin I can't decide what it was. I am guessing silicone rtv or anaerobic gasket maker.

What is recommended for sealing axle shaft flanges?

Flange sealant loctite 515 that CNH uses is pretty good and works as a locktite also for things that commonly work loose

Not totally familiar with the application, but for successful gasket making i have been using “the right stuff” from permatex, I really like it and it is oil ready by the time you get the bolts tight. Comes in a cheese whiz can.

Do you have picture of axle? That style was used on the older trucks. Not saying the weren’t on 74 and later but almost every brand then used the oil lubed bearings. All the trucks I have seen them on were early 50s trucks.

Oops. It's a 75, not a 76. My other loadstar is a 74.

It has a RA30 rear axle. The truck has a 19,700lb gvw with the original 8.25x20 tires.

Below is a pic from the service manual. Mine has the seal ring removed from the outer nut.

Not that it wouldn’t be used on other hubs but yours does have the five bolt buds. That’s the hubs all the trucks with greased bearings  I have seen them on. Seems like all the mid to late 60s and later ih trucks up here had Dayton 5 spoke wheels. Chevy and others had buds early on then went to their 10 bolt or , Dayton wheels then the others had the newer more bolt budd wheels. Learn something new everyday. That they still offered those greased bearings later.

I have some 51813. It has similar specifications.

I "think" that's just the permatex version of loctite 518. 

Either way its anaerobic. That's what I'd use. Great stuff. Seems like 518 might be better for aluminum as well as steel. Like you said similar specs.
