Weep hole coolant leak... again

Hello,

I just reassembled my engine (and used heat shrink to protect the water pump (WP) seal when fitting the side case). When I fired it up, coolant began leaking from the weep hole once the bike reached operating temperature.

I figured that it was the WP seal, so I replaced the old one with a new OEM seal. I did not remove the side case, I simply crushed the old seal strategically and pulled it out.

NOTE: The old seal was pushed far inwards, almost tight against the shoulder of the WP shaft (2 mm further than flush against the WP surface).

For the new seal, I hammered it using a piece of PVC pipe and a hammer. It went it relatively straight and sits relatively flush with the WP surface. I used heat shrink to protect it from the sharp circlip channel.

When I refilled the rad and started the bike, coolant started leaking again once the engine got warm. This leak seems like it is less "aggressive" than the old leak.

NOTE: I am using a product called Engine Ice. It isn't conventional antifreeze. I doubt that this would cause the problem... I mean a small leak, maybe, but a steady leak... the problem may be elsewhere.

Below are some photos. Please let me know your thoughts so I can fix this thing.

TL;DR. Weep hole leaking coolant. Replaced WP seal with OEM seal without removing side case. Leak persists, less "aggressively".


^^Old seal, bent the edge to remove with needle nosed pliers^^

^^Here is the shaft with the seal removed. Could be useful to anyone wondering what it looks like behind the seal^^

^^New seal installed. Looks alright I think. The blue isn't extra sealant, just the coating from the outside of the seal^^
Thanks from tourist

in the second to last photo there is a fairly decent scratch in the housing bore .. maybe thats it.. maybe not

otherwise the only thing you can do is get a different seal and put it so it does not run in the grooves on the shaft ie 1mm or so in a different spot.

So this one is in a different spot than the last. The old one was push in 1-2mm deeper than this one, so I don't think it's a groove issue.

The side case is beautifully sealed... damn, I don't want to split it for a more thorough investigation...

I haven't tried this yet. It seems that 10x18x5 is the standard size when I look at various bearing/seal vendors. They also sell them in 10x18x6

Please explain why 5mm width works better than 4mm? Does the actual sealing surface change, or just the depth of the housing (steel/rubber outer seal cylindrical housing)?

not sure if its better than the oem one i used one because thats all i could get

the outer diameter of the oem one is steel which doesn't seal off as easily as the rubber ones

the best seal ive found for this is out of a ktm 65 part # 46035056100

Oem is x4 but you can try x5 or x6. Those are much deeper then oem and it should stop much pass through coolant.

I ordered two new ones: a KTM (bushie) and a Kawasaki (the 5mm wide one). There are other vendors in my area who can get them, but the Kawi dealer is closer.

I went for a quick ride today. Coolant still leaking, but at a seemingly slower rate.

Any other tips before I try to fix this thing. I would really just like to be able to ride.
