26600012 water pump

Is there a technical reason, other than "Made to fit", that a Bosch water/air coolant pump would not work in place of the stock HD pump? What is the current draw of the stock pump at 13.5v?

I have a stage 3 since new, was the first one they installed at this dealer. on the new M8

Is there an upgrade and should I get one?
The upgrade just came for the twin cams, and basically it seems to be the same M8 pump as you already have.

There is no need to replace the old pump until it fails, it seems also that HD recovered the obsolescence because in their logistic database it is not anymore marked as such.
Last time I checked, in Europe 260 pumps are available but they are all sitting in a unique location in Belgium, meaning that in case you need one you have to wait at least 3 to 5 days to have it. Having one in the saddlebag is a good insurance policy for your road trips here......

The dealer explained to me that in the case of pump failure the computer lights up the engine overheat indicator as a warning for low to no coolant flow, it doesn't necessarily mean the engine is actually overheating. This is why both the CE and OH lights come on simultaneously, even if the bike isn't any hotter than normal.

These pumps are junk. Just the other day I saw another RGU up at my local dealer waiting for a new pump, but they are having trouble getting them in stock. Like noted in this thread, the pump has been obsoleted, and there currently isn't a replacement P/N available.

Could get real ugly if they don't come out with a new pump very soon, because these things do not last.
This is good info, but I do consider 270ish pretty darn hot, and it was a 60* morning.

I'd love to get my hands on those old pumps!

The M8, like yours, have a different coolant pump, it is a variable speed one and controlled by the ECU. This is the reason why it has a different part number from the TC ones

Edit: Initially I was thinking they were the same, but within the discussion here we discovered it is a different one (page 2)

Ronnie's Harley-Davidson's 2017 Harley Davidson FLTRU ROAD GLIDE ULTRA (KGL) | COOLANT - PUMP/HOSES Parts List

Edit - there is a listing for the part number you reference for a 2015 CVO RG Ultra, but is it different from the one's on a 17+?

The unfamous and unreliable Coolant Pump 26600012 is marked as “obsolete” in the HD parts database, the availability at dealership is very scarse and no alternatives are available at this moment on the market.

Despite it looks like many automotive liquid pumps like the Bosch ones, in reality it is “built to fit” only HD, so no commercial replacement is available at this time.

In preparation for my summer road trip i asked yesterday my friend to buy one in the Philly area, the dealer had one, THE LAST, and told my friend he was lucky because there are few available around and no immediate alternative from HD is foreseen at this moment. The pump cost was 459$

The risk is that if it fail on a road trip and no pumps are around your area to face the following choices:
  1. being stranded for days waiting for a spare to arrive
  2. Stop the trip and tow the bike home
  3. Rent a car or bike to carry on the trip and recover the bike later on
  4. Continuing riding with no pump risking of damaging the heads (water cool down mostly the exhaust valves)

Any of them is an expensive option......

In light of the fact that the pump soon or later will fail, I decided to invest in peace of mind and I will take this spare pump in the bag just in case. It is possible that my’19 will present a different pump that could be retrofitted in the old models, but it is just my assumption. In the meanwhile, the riding season is now, I’m going to North Cape - Norway and I do not want to remain stranded up there for an obsolete part.

Just to bring the thing to your attention for the proper considerations if you are planning a big summer trip
