Sand in Water Pump?

Hi there,

I have been reading all the posts for a while and just got my bike services. It is a Yamaha WR450f, 2005, and 481 miles.

It was sitting for a couple of years after my move to Vegas, and I only rode it one time up at Apex. During that ride, the rear tire got buried in the sand, and I had to push it out. The idle was running high the whole ride, and it was a short adventure.

Finally I took it into Sam, at Sam's Cycle Supply. Highly reputable, and great guys there. They fixed the clogged jets, and reported a broken water pump seal. The coolant system had a bunch of sand inside!:moon:

I am now confused, and he wanted to know what I was doing with this thing!

One trip to the dunes, and I managed to befuddle a professional mechanic. No answers, and no idea how this happened. :thumbsup:

After this I am very leery of going anywhere near sand, so any advise would help. This just cost me $535.00, so I am not interested in repeating this.

Great forum, and I appreciate any replies,:p

Only one way possible...well in reality there are others. Had to come in through your radiator. Or I guess it could have been sucked in the head through your intake, then pounded out through the head gasket. The gasket would have to re-seal, and auto rebuild your motor as it would have been smoked. That being said who the f knows. That sounds way out there.

personally i have taken hand fulls of sand out of water jackets on automotive engines .it probably just didn't get cleaned out of the block properly from the original casting .

sure it wasn't silica from high silica coolant that you shouldn't be running ,especially in a Yamaha .

i would just flush the cooling system and call it a day .

More than likely that some d!ckhead sabotaged your bike by putting sand in through the radiator cap while you were otherwise occupied. Next question is, "who's pissed off at you"?

Texas,

I thought the same thing, and unfortunately there is only one person I let ride it, and he works for me.:banana:

Sucks to think, but this validates why I trust few people in this world.:lol:

If I thought it, the mechanic is puzzled, and you thought it, then I am probably right...

Thanks,

Phil

i thought it but didn't want to say it , who would seriously do that . and you would think they would do it in like the gas tank not rad cap .

Sand would be too easy to find in the gas tank. It has to go through a filter to get to the carb, and there you would find it easily. The thought of putting it in the radiator though, was just plain diabolical. Loosing your water pump seal miles out in the dessert....well, imagine all the negative endings to [that] story!
