Bearing retaining compound

[Donald]

So I was told to use a bearing retaining compound for a bearing in the raw water pump of 300 HP boat engine. It's between 1.5" and 2" OD.

Like ice cream, many flavors to choose from. Bearing gets pressed in so not sure why it's needed.

Six flavors in the 600 range from this company. Bearing may need to be changed in the future.

Probably different based on materials being used, but on the 7.3L diesel injector cups, Ford wants us to use Loctite 620.

I believe that the difference is mostly the gap filling ability, strength and temperature tolerance. Here's a comparison of a few versions of retaining compounds.

You probably need the activator/primer too because of the metal used on boat parts.
