I don't know for sure, but my understanding, based on what I read, is yes....

It appears to replace the #62400125 cover oil pump assembly part, on the '17 & '18 M8 engines. One thread had it being ordered by a dealer, at the direction of a MoCo Rep, for a '17 or '18 engine that was sumping.

Like I said, no one is declaring victory yet... Damn, there have been so many oil pump changes that the MoCo stopped changing the part numbers... This will have to have some time/miles behind it, without issues, before anyone should jump to get one.... unless of course, you are one of the people with a sumping problem... then have the dealer get it under warranty... if they're not aware of it already.

 

i know others have talked about the poor case design. But if both the Feuling and S&S pumps have solved the problem why should a case re-design be warranted. We are talking about the MOCO here. You know the ones to use the cheap Chinese bearings to save a few pennies. How many hard saddlebags had to fall off before they designed the current and superior screw system. Boy I bet the bean counters lost some sleep over that one.

 

Another forum member is getting the plate installed due to excessive oil carry over into the air box. His isn't sumping. I have the same issue and that's what HD recommend for him.

 

I believe the difference between bikes that sump and bikes that don,t might be related to what the auto makers call "stacking". 1 . Poorly designed flywheel area oil pickup passageways. 2. Poor piston ring to cylinder seal. Sometimes out of spec/round cylinder bores. some pictures have been posted showing this on cylinders removed for big bore kits. To much leak down and blow by.....3. Poor quality piston jet gaskets and bolts that may reach torque spec before securing the jet. GMR I think and someoe else said that this MUST be checked when replacing the gaskets (with cometic ones). 4. Oil pumps.......Who knows..I would compare this oil pump saga to a boat manufacturer that reveals a new model boat (does millions of miles of testing lol) and has hull leakage problems...THE ANSWER replace the bilge pumps with bigger better pumps to offset the leakage problem. Oh yes and don,t address the ROOT CAUSE of the problem...Just the symptoms and continue on that course for oh say 2 or maybe 3 model years.. The models are very popular and there is a loyal to a fault customer base...The leaky boats will be out of warranty soon enough..
Like said in a post above....I love my harley but do not trust the company.. I have had no transfer or sumping (at least to the point of failure) as of yet. But my warranty will time out in the next few weeks. 2017 RGU.. No trust no 2019 for me. Rant over I.m going out for a cruise on my HD boat.. Max

 

 

Many complaints here against HD with their flawed cycles but I hear/read NO class action lawsuits being filed. Why is that? Could you imagine if Ford's F-150 had serious engine flaws? They'd be in court (as a defendant) in a few months if that.

 

Well, go start one....

Unless people are dying, and even then there's no guarantees, nobody wins in a class action lawsuit except for the lawyers...

 

Based on what, exactly? They're fixing the bikes, what more do you expect them to do?

 

2018 road king, that was my last Harley. Last month I trade it in for a awesome Moto Guzzi California.
