Raptor impeller

**RUGER761** · 08-19-2020, 10:34 PM

So had my wife bump started to check direction and installed it then bumped again to verify before putting cover on. Turns out only the 3 veins were correct the others were backwards. Wear pattern on the cover shows it’s was backwards as well. Be interesting Saturday to see what temp it runs now. It’s always been around 170-175. Do the CEL clear or will I have to take it in to have it cleared?

That's what i thought looking at the photo.
On the new impeller are the blades straight or curved?

New impellers are straight, during install you need to orientate the vanes.

Yep I'm glad I double checked it. Surprised it even worked as long as it did. Correct straight veins and you twist installing just like any of the older impellers. Looks like the same pump that V-drives have had for a long time. At least its easy to get to, some are a stand on your head nightmare. Ordered and extra one to keep in there now just in case.

It almost looks like someone took the original out and flipped it around.
I can't figure how the vanes ended up curved that direction when it spins the other way.

I guess I never pay attention to which direction it rotates when I change it, I always assumed the engine would back up or reverse rotation a little bit when it stops anyway so the fins would flop backwards... Maybe I'll pay attention a little more next time and see

Ok thanks I appreciate it

Well it wasn’t the impeller causing the issue. Still heats up after long pulls but cools quickly at idle or slightly above idle right back down to 160. So it’s headed to the shop Monday to see what they can figure out. Hopefully something simple and quick to fix.
