Impellar

[JesseC]

Tazz, it is the Johnson 812 impeller. A lot of people pull the plate and then pull the impeller out leaving the pump on the harmonic balancer. I prefer to pull the entire pump off of the harmonic balancer to inspect the internals. There is a Wear plate on the top side of the pump that sometimes get impeller edges stuck to it, they appear as black line residue and I like to get all of that off so it does not "sand down" my new impeller. I also like to check the play in the bearings. I then use plumbers grease to coat the impeller and inside the housing to help the friction from the first start of the year where everything in there is dry. The first time you pull the pump free of the harmonic balancer is an absolute b!tch. Now I can pull the pump, coat the impeller, reinstall the pump and hoses in about 30 minutes. Get some emery cloth to polish the edge of the pump and inside of the harmonic balancer. This will make the next removal a breeze....hope this helps.

I purchased mine from skidim
