Water pump rebuilding service.

:hello: I have no room for powder coating. The time that I used our oven to bake on paint my wife came home from work & smelled paint in the house & asked was you baking parts in my oven again. :laughing7:

R. J.,

If I'm sending you $25 more ( well deserved I might add) , you should let me send more$ yet and let me take that rear fender off you.

I'm going to be inspecting mine during the build. Probably rebuild it while it's off and it is great to know the parts are available.
 
:hello: Guys awhile back I bought this external bearing puller off of E-bay $12 shipped. I used it on the last 3 water pumps that I rebuilt. It's just the right size for going around the shafts. It works great. ________________________________________________________________ IMG_2621.jpg IMG_2622.jpg IMG_1629.jpg

:thumbsup: Do you think this will work to help with pressing the bearing off the shaft? Actually all dimensions can be altered...

So then, I can reduce the slot to say 1/2" and it should work; for pressing the bearing off the shaft.
 
:hello: Here is the dead blow & sledge hammer that I use when doing water pumps. They are the heaviest that I own. Again I rarely use these. A press is still my choice for pressing the shaft out of the housing. When using a press you will not damage any components & it is much safer. IMG_2627.jpg

If you could post pictures of your progress, some, if not all of us, would appreciate it greatly.
 
R.J., I edited the water pump part # to show the correct one. The seal # I changed to question marks and can be changed again once the correct # is known.
 
Thank's Martin. I do remember getting the water pump oil seal part # from another thread but when I did a search I could not find it. Hopefully someone will chime in with the OEM part #. I think Markus knows the part #. Thank's again.
 
:hello: I received the 2 OEM mechanical ceramic coolant/water seals (part # 49063-1055) in the mail today. Cost $16.58 each. See pics for all dimensions.IMG_4079.JPG IMG_4080.JPG IMG_4074.JPG IMG_4075.JPG IMG_4076.JPG IMG_4077.JPG IMG_4078.JPG All measurements are in MM. In pic # 7 this dimension may very because of spring tension. So in pic 3 it being 32 MM O. D. lip to lip must mean the older water pumps use the 35 MM O. D.

:hello: Kaw OEM mechanical ceramic water/coolant seals part # 49063-1055 $16.58 each. They are the 32 MM. I have 2 pumps that need the 35 MM. Another member found the 35 MM at a good price. Does anyone know who it was. I thought just maybe that I would be able to take the seal from the 32 MM cup & put it in the 35 MM cup but it was a no go. _________________________________________________IMG_4145.JPG IMG_4146.JPG

:laughing7: Some time ago someone asked the O D of the water pump shaft. It is 12 MM & the O A L is 72 MM. The 72 MM measurement is with the white ceramic seal seated into the propeller. _________________________________________________________________________IMG_4147.JPG IMG_4148.JPG

:hello: UPS delivered my KAW OEM parts today. Still waiting on a few other carb parts. The 2 mechanical seals that I got are a no go on the 35mm one that is used in most of our water pumps.The left one in pic is part # 49063-1056 is a 29 mm O D lip to lip & the white seal I D is 12 mm $14.58 Top middle in pic is a 32 mm one part #49063-1057 with no white seal $32.16. Don't get this one. Bottom mid is the 35 mm one used. Still can't find it. Right one $14.58 in pic part # 49063-1055 is the 32 mm one with white seal I D of 14 mm. Get this one. So the search continues for the OEM 35 mm. Again does anyone know of the person who found an aftermarket 35 mm mechanical ceramic seal. I think he got it for around $10 from AMAZON. I did look on Amazon with no luck, except for one 35 mm that states the 35 mm measurement is I D. ____________________________________________IMG_4215.JPG
