Used to install the crankshaft front oil seal installer to the front cover on 4.8L, 5.3L, 5.7L and 6.0L engines.
When used on LS7 engines, GM-47812 is also required.
Smallblock V8 engines utilize a Teflon lipped front seal. When installed correctly the seal provides superior oil containment. It must be drawn squarely into the bore of the front cover and carefully to avoid damage to the inner lip.
