Picture A - spring always faces what you are trying to seal against.
Tape the end of the shaft and apply a bit of grease when you assemble so ypu don't damage the lip.
 
beg to differ

are we not looking at the water pump :eek: if you say picture a then the spring would be in contact with water all the time not good for the life of the seal it has to be picture b :D
 
RE: beg to differ

Picture a is the correct way.
The water in the pump will act to place pressure on the inside of the seal thus "sealing" it
 
RE: beg to differ

Picture a is correct. Most times it stops after you have run the engine a little. there are old mark on the shaft from where the lips from the old seal was. now when you put in the new seal in its maybe off with just a couple off 0,1mm, from the old position, and its just need to be running in. I think is should be okay, if you drive if for a while :wink:

Thats offcorse. if you got the cover on and didn't scratch the seal against the circlipgrove on the pumpshaft, its usually has a very sharp edge, and the seal-material is very easy to scratch. Its a good investment to get the special-cone-gard-tool that you can get from the dealers.

One thing I do when I shift seal is to take a little bit off 400-600 wet-and-dry paper and a flat shoelace. roll the paper round the shaft and run the shoelace 2 turn round and then Polish the shaft, and then you can take 1000-1200 wet-and-dry to get it real fine surface. I have never had a drop off water leaking :lol:

did the spring ping out from behind the seal?

To do a complete waterpump seal overhaul you need to replace three parts:

The seal as you have replaced

The o-ring which goes on the balancer shaft (water pump shaft)

The water pump bearing/seal (see pic below)

Something I would like to add to this, for what it's worth. The mechanic at the KTM shop in Grand Junction, CO, showed me a trick he uses when installing these seals. He takes a Dremel tool with a cone shaped abrasive bit and lightly chamfers the metal about the hole the seal is to be pressed into. He then uses a non-hardening sealant around the outside of the seal as an installation lubricant, and as a sealant. He swears that these seals will leak around the outer surface. I'm not going to argue with him, the seals he installs don't leak.

Is the entire hole somewhat hogged out at a taper or is only the leading edge of the hole chamfered. What does the chamfering accomplish?

I dont remember a ping, anyway im gonna install new one today... do i need hear the spring ping? and if i dont then what?

one more question - how to you get the seal in? do you heat the cover? with simpel pressing it aint go in....

husabutt - you not gonna belive it but i went to my local KTM dealer and they try to find this bearing on the computer but useless, they dont have that bearing even in the catalog. Then i showed them this forum with your picture, but still nothing! Anyway i can get the bearing but not the plastic cover... any idea where do i get this plastic for bearing?

Hope you understand.... my english sucks hard.. 8)
 
B - put some electrical tape around it.
Do as swedish says and polish up the old seal marks witha bit of wet and dry with oil.
Grease it all up liberally with vaseline or whatever.
Use some sort of sealant around the outside if you're using the steel cased seals.

Just order by part number 0625062013. You can't purchase the cover sepeately.

If you look up the the "clutch cover" on the parts diagram its listed as "Ballbearing with se", se for seal. Number 63 on the site listed below.

Regarding my previous post about chamfering: The chamfering of the hole that the seal goes into is the removal of a tiny bit of material at the sharp edge of that hole. Maybe the width of a fingernail. A 45 degree edge would be good. This bevel at the leading edge to the hole greatly helps with the entry of the new seal. Removal of too much material would compromise the contact of the seals outer surface to the case.
