Water Pump Impeller Question

7 posts in this topic

Hey guys,

Long time lurker here.   Love the site as it has provided a lot of great info thanks!

Question about my bike.   I just did and overhaul on the waterpump on my 2012 raga,  and have a question about the impeller.

I had to press the assembly out to replace the seal and shaft,  but I think I damaged about half the threads on the impeller being a monkey with it.   I re-assembled,   and I feel like there is still some good bite there.   Until I get a replacement impeller,   would I be foolish to run the bike?   As the impeller is moving water,  and the crank shaft doesn't spin very fast,   I imagine there isn't a lot of force on the impeller.  It felt pretty solid to me still.

Should be good provided a to-spec fit and all the bits are where they should?

Also,  I used 10nM.   does that sound right for torque?

 

Thanks!

Personally while it is in pieces I would wait until a new one arrived.....probably a day to wait.

You might ask Gas Gas questions under Gas Gas to get a better response. Unfortunately the best video to replace the seal was removed from the internet by stupidity. A screwdriver and an allan wrench was all that was needed. I would fix it proper, as a spinning impellor could cost you in the long run.

ok guys thanks.    I will swap it out.   are the aluminum billet units of any value?

Plastic one seems fine, I never had a problem with one or heard anyone say that they had either.

My wife's Gas Gas is still running fine on its plastic one.  :thumbup:

I haven't ever seen or heard of issues with the plastic ones on Gas Gas.
