Okay, I set the TDC bolt on the bottom of the case (6mm Allen Head) and wrapped the water pump shaft with a small piece of nylon window screen and small piece of masking tape. I tightened up a medium sized Crescent wrench on it and gave it a couple jolts. It loosened up no problem.
I layed the bike over on its left side, resting on the handlebar end (not good. I know. But, I didn’t want that pump gear going anywhere down the cam chain shaft)
I slowly backed out the water pump shaft, standard rotation, until I felt it click at the end of the threads. I slowly pulled it out. The outer seal came out on the shaft. It was probably spinning around in the housing.
I ordered the factory seal. But, it appears to be about 1mm too big for the housing at the outer diameter. I can’t even imagine it fitting in without crushing it. It is a super hard rubber so I am stumped about how to put it in without destroying it.
If anyone has any wisdom it would be greatly appreciated. Thanks in advance.
I am just digging into this project. My question is, do I need to remove the carburetor from the bike (basically disassembling the entire bike) to remove it? Or, is it possible to loosen the clamps and swivel the carburetor to access the bottom and the jets? Sorry for the cluelessness.🤪👍
Oh! One more thing. Do I have to remove the pump shaft in order to replace the seal(s)? My bike is a 2017 with 10 hours on it. I think the seal(s) just dried out. The shaft is probably fine.
This thread saved me. I was ready to tear the Head off my bike for a leaking Head Gasket. Thanks for posting. I am waiting on parts. So, I have not removed anything yet.
Does anyone have anything new for the good of the order? Can anyone provide any more details on how to make the tool for removal of the pump shaft, photos, different angles, other solutions, anything? Beta should provide a little something for this when you buy the bike.
Any additional information would be greatly appreciated.
Thanks for the information so far. I have no idea what to look for, other than a disconnect. I will dig into it tomorrow. Anything else helpful would be greatly appreciated.
PS - I put the headlight back on (after a big overheat) and then the fan worked.
I have a new to me 2019 EVO 250. I need to remove the front headlight to fit a number plate. The problem is, when I disconnect the wiring to the light and ignition mode switch (also on the headlight mask) the cooling fan stops working.
My question is; what is the fix for this?
Thanks for any assistance.
PS - I am no electrician so please be specific or post a photo - Thanks.
