I agree Bob, i've had plenty sump on the dyno. A early 114" build I tuned I could drain 18oz from the crank sensor after 4 pulls to rev limiter.

 

A good friend of mine just had his 2018 do this, the dealer is saying they can just put on oil pump on it and he'll be good to go. It completely quit on the highway at speed. Sounds to me like they should replace his whole engine.

 

I should have avoided the word "never". Its highly unlikely that a DEALERSHIP is going to run a bike on a dyno long enough to identify sumping. But its certainly possible that if you run a bike long enough (over 75 miles IMO) its certainly possible to create a sumping situation. I just don't think the average dealership is going to put your bike on a dyno and run it continuously, at speed, with varying rpms, load factors, minimal idle time and shifting conditions needed to recreate sumping. If you want to be assured of your dealership identifying a sumping condition in order to make a warranty drivetrain claim, you are best off riding it under the conditions that generated the concern about sumping in the first place and ride it straight to the dealership under those conditions.

Otherwise you are very likely to get the dreaded "we can't replicate the sumping problem" response. But those that feel differently can certainly rely on the dealership dyno to try and recreate your sumping condition, just be prepared for alot of frustration. I stand by my original recommendation that the simplest way to get HD to honor a warranty claim for an engine that's sumping.is to ride up to the dealership service door while the bike is sumping. I've been through enough sumping engines to have learned the lesson but everyone is free to do as they think is best for their situation.

 

I actually videoed me letting checking it after a long hot ride with it sumped when I got home. I have the video of me letting it idle, video of me pulling the crank sensor and the oil pouring out. I placed the oil in a water bottle and sent it with the bike. I am honestly getting pissed with the run around. I am pissed the dealer that swapped the pump didn't call Harley, didn't perform the check as required by the TSB and the list goes on.

 

Thursday they said the bike was ready to go,they couldn't recreate sumping,i told them to ride it like they stole it,run it hard because im going to when I get it back.they took it out for another ride and this time it did it,they said the oil pump went out and they are tearing into it finally,seems like they are dragging their feet,friends are telling me to call corporate and complain but I don't want to if they will fix it right,we'll see

 

Make sure they fit the latest pump with the rear cover oil seal, as fitted to the 19's

 

Heatwave, I called the dealer this morning to see how it went with my bike yesterday. He said it's done. I said "no s**t?, awesome. What did you do?" They said they replaced the oil pump and seal. I was a little concerned so I called the sales manager I bought the bike from and he said if I had any concerns, I could talk to the master tech when I show up. I logged into this forum, read SB 1450, and called them back. I asked service department if in deed it was sumping and they said if I pulled that much oil out of the CPS port (2 1/4 Qts), it must be. I then asked why they didnt follow the service bulletin and service rep now started to get a little pissy with me. He said "now who's fixing the bike here?" He said if I had any serious issues to the internals, the bike wouldn't be pulling the numbers it did on dyno. His other impressive comment to me was "my technician was pissing around with that bike for half a day before he decided to replace the oil pump and we changed the oil pump because we knew there would a problem". I presume he was implying they would have a "problem" with me. What do you recommend?

 

 

Copy that. Thank you Sir.
