We can but hope (and I imagine I'm not alone in that hope).

I'm not new to HD, I know they've always been a bit... fixer-uppers. (I used to have an '88 softail)
It's just that the engine... the heart... going wrong and unfixable? Nah...

Looking at the spare parts identifier for a 2018 vs 2019 short block, it appears the part numbers are the same. So I am not so sure what you actually got with your new motor, but it doesn't appear the crankcase is any different. Have you actually heard more since the 2019 are out?

No.... I have not heard anything more about what, if any, changes were made to the M8 case for 2019. Its also possible the case part # "didn't change" but the casting or milling process (or both) was improved to ensure existing specs were being accurately met or improved clean up of milling surfaces was modified. Not sure if a manufacturing process improvement would result in a new part #. Just another thought around the 2019 engines being "different", if in fact they are different.

I wouldn't be surprised if all existing M8 case inventory was returned to the casting facility for recycling, if QA had any concerns that the cases on the shelf, before a specified date, were considered "out of spec" Just another hypothesis.

Seems like they are shipping 2019 cases now for 2017 and 18 that sump. Two friends had thier back sump and got new cases. Supposed more drain holes to get the oil out of the sump faster. two week turn around forces is what they have seen. Replace everything else bearing wise, rings etc.

Oil building up in the sump isn't the problem. Oil building up in the crankcase is.

When my motor sumped a second time, they tore it down replaced the entire pump, and reassembled it said it was good. I returned it the next day. Compression was way down bike ran like ****. Tech center sent a plate/pump part, no part #, in a padded envelope. They installed it, never taking off the top end just the rockers, compression was back to where it is supposed to be bike runs good as ever. Have over 700 miles on it since the repair no motor issues.

sounds like you have the latest fix for this issue straight from Harley. I saw the new plate and the pump part...I heard it costs $16.00 and is reported to solve the sumping issue.

Keep us informed

It's interesting for sure. Looks like it's stock on the 19s. A $27 dollar part that replaces the old rear oil pump cover with one that has a new oil seal incorporated into it.

Probably requires the newer oil pump (62400182 in my case). I'm running the as delivered pump from fall 2016. I might look into this to alleviate future issues. I hope more people report back...

no...it doesn’t require the new oil pump.

My bike was purchased the first weekend the 2017”s were released (and I haven’t had transfer or sumping issues)

Ok, cool. I've only seen the new cover plate associated with the newer pump (62400182), but you are saying you used it - or someone has - with the original OEM pump (62400124)?
Those are the Twin cooled variant numbers respectively.

I would probably just buy the improved pump anyway, but would be good to know.
