Keep the crud out of the weep hole

Haskell in Idaho told me about this fix he made for his 09 570 to keep the junk out of the weep hole, and the water pump shaft area. Anyone who has replaced their water pump seal on the 09 on up bikes has probably found a good deal of grit in the area between the water pump seal and the engine oil seal.

The weep hole is at 3 'o clock, so anything that get's in there can't just fall out. And to make matters worse, the weep hole points forward, so when riding through a stream or mud, it naturally ends up on the weep hole and then ends up down inside between the seals.

Haskell recommended that I just get a piece of 1/8th" tubing from the home improvement cent, cut it to length, put a dab of epoxy, I used JB weld steel, on the tube and gently tap it in the weep hole and then attach a short piece of tubing to it and secure with a small piece of safety wire to keep the crud out, yet you can still see if you are losing a seal. You do have to pull the water pump housing off to get to it, but the juice is worth the squeeze!



Thanks from batfreek

I'm not sure what you're talking about, can you please be more specific?

Re: Keep the crud out of the weep hole

Ah, I get it now, aluminum tubing...did you have to drill anything out? It looked like brass tubing there. Didnt see the safety wire in it, it looked like a bit of barbed tubing off an old carb drain...

Re: Keep the crud out of the weep hole

Just came back from the small local hobby shop. Found 1/8" brass tubing with hose (for R/C airplane gas tanks) for $2. Cut down about 1" of tubing attached hose...tapped it into the hole with a socket on a long extension...kinda like driving a fencepost.

Why didn't they do this at the factory? It was just that easy.

Re: Keep the crud out of the weep hole

Nice tip, Dale!

I'm now at 2020 miles and have seen a *lot* of mud and stream crossings.
Should I remove the cover to do check-n-clean first?

Cheers! E-Ticket

You would have to pull at least one of the seals out to get to the area in between to get the crud out. If you have the time, then I would do it now before the grit ruins your water pump shaft.
