My 2018 SGS was built in July so I have the original oil pump. So far so good here. I plan to keep it stock so I doubt I will have problems. Still, its good to know so I can keep a close eye on. If I ever have an issue, I will bring it right in to get the pump swapped out for the new version. Happy I bought the 5 year warranty just incase...
So, back to the question. 2018 M8 ----sumping? Failures? Or are we just into bitching now.
There's another thread from an owner with a brand spankin' new 2018 Heritage Softail Anniversary with the 114 cu in M8 motor.
It ran for 25 miles before it started losing power.
Edit: Found it...

Fastest speed I could get to was 25 mph. The bike's been at the dealer a couple of days and the factory tech will be at the dealer tomorrow. Hopefully they find the problem. They've already replaced the throttle body, changed out pin connectors and repaired one broken wire.

Yes, but point being -- they've had six oil pumps already for the M8; the "revised" oil pumps make #'s 7 and 8. And IINM there have been reports from owners that even those part # oil pumps have sumped on 'em.
Maybe when they get to revision #20 or so, they'll start looking for the actual cause of the sumping issue.
But then again, it's the MoCo, so maybe revision #30 will be the tipping point.
Frankly I would be reticent to do anything until the sumping issue is solved. As Mr. Coles mentioned they are now on their seventh iteration of an upgraded oil pump. I am afraid they may be using the ole swag method of solving this problem. SWAG = Scientific Wild *** Guess!
100% agree - except maybe drop the "S" part. Nothin' "Scientific" goin' on at the ol' MoCo. Never has been, never will be.
I have in the office 6 different pump designs. Many of them have the exact same part number on them as HD did not change the part number nor add a version number. For awhile they were adding small marks on the pump body but at some point stopped that too. So this is why its hard to track them all as you can get the same part number today as you could before but they are different pumps. Thats just why with the current part number you must also look for date code on the box. So the Service bulletin doesn't come close to telling the whole story.
Now in the past every manufacture I know of revises the part number when the part is changed! HD used to do this as well, but for some reason has stopped and just decided to change the part and leave no paper trail it was changed!
If at all possible, could you share some (detailed) pictures of all of the (different) pumps, please?
I might not need it since I am on the second engine on my '17 CVO, after two different(?) oil pumps in initial engine. But who knows when the engine was built and with what pump...
Many of them have the exact same part number on them as HD did not change the part number nor add a version number.
that is because it isn't a part number, it is a casting number, take two items with the same casting number, machine them differently and you have two different parts and two different part numbers but both items have the same casting number, this is not something new, HD has been doing it for years
While I haven't seen it yet, my understanding is that even though the casting #s remained the same (pre vs post Oct 11 2017), there is a new added "dot" after the casting # designating the later version. Anyone see the later casted pumps and if this "dot" exists?
