If the bikes coming off the assembly line now have twin cooling, which they do, then it stands to reason that there are pumps.

And that they'd supply them to people who need replacements.

From the research I’ve done, it seems the M8 pumps are different. They are now variable speed and ECU controlled. There is no thermostat either.

Thanks for the info, have a few questions. The connections look like a circuit breaker, are they supposed to break the circuit at some point? Does the pump run all the time now? If not then maybe we should take apart and weld them together. This should be a recall on all wet heads. I have a 15 Limited Low and have not had any problems YET but only have 10k miles.

Kenny, that is correct from what we learned from a tech that replaced my friends pump at Man Of War HD in Ky. I actually have my ole waterpump that I swapped out before my big trip to South Dakota just for a pre-maint type of deal but it was still going with 36,500 miles on the pump. I'm going to keep it for a spare but may pull apart to inspect before I keep it in my bike.

The contacts appear to be "spot" or "resistance" welded, I do not believe that they are supposed to open at anytime. I am unsure if the pump runs 100% of the time-but I think it does. If it does not, it would be controlled externally via a temperature switch and/or ECU. This would be good research in the tech manual.

Recall's are for safety issues, so you would never get them to do a mass recall. They may do an extended warranty on that part alone if there was a class action suit, but they would not do it on their own out of the kindness of their hearts LOL.

yep Harley really sucked the bag on the Rushmore pumps
everyone who has one knows its like rolling the dice everytime they ride
the rest of my bike is great and would be better if they came out with a replacement new design pump for all of us

By the way, the "stupid non-reusable Crimp Clamps" are called Oetiker Clamps. Yes, they are not reusable, you need to start with the proper size for your hose/fitting, and they need a crimper to install. They are, however, superior to worm drive clamps. They will give 360° pressure on the hose/fitting, they can't work loose, and they won't cut into (damage) the hose.

​​​​​​​Just FYI.....

A guy I know just lost a Water Pump at 15,000 miles on his bike, he was on a trip to Yellowstone. Seems the long trips really play havoc on these sucky azz pumps.

That's what I used to think. But it's not true. They are only required have have parts available to cover warranty claims. 16 was the last year that pump was used. The factory warranty is only 2 years. I got the info below of the "ask an attorney website.

A consequence is that vehicle manufacturers must be able to provide parts during the term of a warranty (if any) made at the time of sale. They need not make or stock these parts themselves.

Vehicle makers could choose not to do so, but then they would be required to provide a replacement vehicle or a full refund of the vehicle cost. In practice it is usually more cost effective for makers to procure replacement parts to effect a warranty repair.
