TT466 UPDATED OIL PUMP FOR MILWAUKEE-EIGHT ENGINES

hd06 · August 22, 2019, 06:06:25 PM

That's great before too long these m8 will be bulletproof.

FloridaJim5 · August 23, 2019, 11:25:28 AM

Can this pump be used on all M8's or just 2020?

BigT · August 23, 2019, 02:31:57 PM

All M8s

I'm just having the SS pump installed on my 19 CVO RG when I have the 128 big bore kit installed next week... Finally H-D is building a better pump to start helping with all the sumping issues, hopefully it works..

Jaycee1964 · August 28, 2019, 06:47:08 AM

I guess I have been blessed. 2018 RGU with over 15K on it in 11 months. Never had any issues with sumping.. Now I went and Jink'd myself.

HV · August 28, 2019, 05:14:19 PM

Ohio HD · August 28, 2019, 05:19:43 PM

Latest, latest, latest,,,,latest pump? lol
Primary vent?

HV · August 30, 2019, 05:29:30 AM

Update.....we found the Sumping reason.....rear piston jet loose....you could wiggle it up and down with ease ....

primary had no vent ....does now....

Hossamania · August 30, 2019, 05:40:52 AM

So with all the updates and awareness of the known issues, they still have not updated that part/design, and the process of assembly? Is it just too much work for them to try and solve all the problems at one time?

So once again the sumping problem occurs, caused by a known assembly problem or defect. Any damage to the engine? Will HD authorize a complete inspection of the engine or just say put it back together and it should make it to the end of the warranty period. Will it get the latest & greatest oil pump? And this is why I think I'll keep my Twin Cam.

HV · August 30, 2019, 08:17:21 AM

Complete tear down and inspection.....new updated pump will be installed as well as Vent for Primary

14GuineaPig · August 30, 2019, 10:03:00 AM

Well that's good news. Glad HD stepped up and is taking care of the customer.

VDeuce · August 30, 2019, 11:01:39 AM

HV, when you guys handle the oilers, do you replace the gaskets with Cometics?

HV · August 30, 2019, 11:29:13 AM

No have to use HD parts ....I wish they had O Rings like the Twin Cams ....never an issue with them

I was really hoping that I'd see in the 2020 tech forum documentation that they addressed the piston jet issue. So, what are we supposed to do? Buy a new bike, take it home, and immediately tear down the engine to fix the jets? The thought of internal hemorrhaging in the engine makes my skin crawl.

rbabos · August 30, 2019, 01:22:50 PM

Pretty sure after what like 4 revised pumps the pump was never the issue. More like extreme internal leakages for whatever reason, overpowering the scavenge side.

PoorUB · August 30, 2019, 01:46:40 PM

Ron, when are you guys gonna come up with a fix for everything so HD can steal it. Between the bean counters and underpaid engineers they are never get this M8 straightened up!

HV · August 30, 2019, 01:48:06 PM

You dont want to know how many bikes found sumping had loose piston jets ............

Prostock · August 30, 2019, 02:01:17 PM

Anyone have the cometic part number. Have a 17 in the shop for sumping and transfer.

Txwezl · August 30, 2019, 02:31:45 PM
