Now that the M8's have been out for a while and getting sorted out, what's the latest and greatist on the oil pumps? Have they done any upgrades since 2020?

The 2020 pump seems to have abated the sumping issue, as long as the piston squirters are tight.
Ignorance is bliss, and accuracy expensive. How much of either can you afford?

Do we know when the new oil pump was used in production?  Was it Job 1 2020 or was it a running change in 2019?

HogMike

My 2019 was a late production and still had the old style pump.
Never had an issue with it.

Went to S&S when I built the motor just for added security!

So, you've seen 2020 or later piston jets come loose?

To answer OPs question. See Link below. Think it was designed for bagger race series. Even with 20% discount its pricey.

Should be fitted from Factory as standard.

The OEM parts numbers for the oil pump and cam plate for a 2020 107" and the SE part numbers are different.

Yes. The SE should be fitted by HD is what i mean as a standard from factory.

Be interesting to compare to their latest OEM pump.  Seems they have spent some R&D trying to figure out their oil issues.  Doubt they came up with different volume or ratio that is really a step up or an alternative.  Just to wrap in billet and put SE on it.

This is good info.

Mine is a 2019 softail.... Does anyone have a build date / month of production for that year that got the latest oil pump?

I'm pretty sure it was at some point in 2019.

Thanks

Google HD TT466, dated 8/20/2019, for info. Last few 2019 models, and all the 2020 models received the new pump.

Thanks Rigidthumper,  mine has 2 different dates on the compliance plate / sticker...
One says "date of manufacture" 02/19
The other says "08/19".

Looks like I probably don't have the latest pump?

Is it worth upgrading? Is the Drag Specialties pump any good?

Thanks

Adam you are up for a pump

Yeah, I guess the question now is which pump to get? the latest HD pump?  Drag Specialties? Fueling / S&S? 
Cost is always a factor, I don't have a money tree 😁

I'm pretty sure the M8 softails didn't have the same issues as the touring bikes.

A quote from APE:


Adam76

Thanks for the info Speedzter, APE sure do build a lot of big inch hotrod motors.  :chop:

JSD

Interesting from Ape. Also why only the touring & not Softail?

Adam76

I see that Twin Power makes an "upgraded" high flow oil pump for M8.... Any thoughts on this pump? Is quite cheap considering.

The Fueling and S&S pumps are expensive and also are listed as only compatible with their own cam plate. So you have to buy the cam plate as well as the oil pump, which is just not an option for me cost wise.

What a great big waste of money , abselutly nothing wrong with the std pump and plate . don't know what the fixation is , and what no one has had trouble with aftermarket pumps. Max

Stateside the factory 2020 pump seems to be mostly adequate, and at $160 retail, not a horrible cost.

Hey Max, when you say "std pump and plate" --  are you referring to the 2020 HD oem pump/plate or any of the 2018 - 2020 pumps that HD kept redesigning?

Thanks

For the touring bikes, the 2020 standard pump and plate work fine in big bore applications.  Do not use the earlier Standard HD pumps, they can sump.
