Newest Comp Version

[rbabos]

Enough is enough. Why not go back to the type of comp that worked great forever? Oh, that's right, we are forced to use this type because the cranks need it 

They tried that early on. It didn't work out with the new primary ratios. Larger sprocket needed stiffer springs to keep the rotational cushioining range to a usable state. A classic example of them not following this rule is the first 07 comps that ran up to 2011 I think. Then they clued into the springs. Enter the SE versions. Sure , saving cranks was part of the goal as well.

Anybody still running the old style comp with an extra washer?

[Richard K]

We have the info we need. This new comp is only for the 2017 and forward. Note that this newest latest greatest assembly still is not match machined on the contact sliding surfaces now add the fact that this offers no improvement to cam/spoke lubrication we will continue to see early failures. Sorry but that has been proven time and again. From what I can tell they may have reduced noise by going back to composite washer and reconfiguring cam and ramp. We will see as we can get real world miles on them.
The MoCo did sell down their stock. Shelves were empty for many weeks. Best guess is they considered a retro version but as was stated want to see proven with real world miles. Time will tell.
We have held fast to the roller thrust being a crap idea and here we are back to the composite washer.
The dealers I associate with very recently received stock of the 64A. I picked one up and verified nothing has changed. Add to this re-release of the 64A and the licensing of aftermarket production and sales, again best guess the MoCo is looking to put the Twin Cam comps in the rearview mirror like with the comps on the 06 and back. They know the aftermarket will cover that market and they can move forward to more profitable ventures.
I have to say this new engine has many concerns for me. It will be interesting to follow what develops.

I Think you are talking about the Style Original on my 09 King?

TweekMyTwin Jim was one I remember about the added spring...

I have the SE08A with over 60,000 miles on it and Still working Great...  (grooved for oil to enter)

Read that WASHER n put in Spring.... The Stack height was measured Then added a shim washer if Necessary (memory) .030?

Maybe Ron will correct me here...

So is this new comp a rampage ramp?
Looks like

[kristian]

they included liquimoly lube as the gold standard in the primary!  smooooth as silk

[FSG]

be interesting to see the other side of the sprocket spokes

[N-gin]

Sorry meant ramp to ramp.

[PoorUB]

be interesting to see the other side of the sprocket spokes

I was wondering the same. You don't suppose HD put a bit more "meat" in that area to get a bit more wear surface?

[FSG]

I do.

Based on the patent app pic, it has an actual lead in profile for the cam and a tad less back and forward rotational slop between ramps. Mind you,  patent item drawings are somewhat cartoonish but so were the  08A and 14 comp sprockets but represented the profiles fairly close to actual. Is it better? That will come out over time.

Seems odd they would remove the oil tray from the primary cover. Instead they mounted a mass damper for sound reduction - which may be in the way for aftermarket solutions to poor lubrication.

The oil tray wasn't an HD part to start with. It was aftermarket.

Unless the parts fiche is wrong. (which it could be) the spring pack for the 107 is the same part number as the old (83936-09A)
The one listed for the 114 is (40100075) but they both have the same part number for the Comp Assy (40100076)

No Bubbie,you had it right the 1st time,I said washer,but I really meant spring.Seemed like that worked pretty good,except you would need a junk comp to get the extra spring out of.

Ron

Not understanding what you mean by this. The spring pack looks to be installed the same way as it is on the pre 2017 SE comp.

Not according to the patent app. Smallest spring is against a lip on the extension shaft and largest spring is against the cam face. Same spring layout, just reversed. You might be looking at some generic pic.

The cutaway of the M8 shows the spring pack installed normally.

Entirely possible, however, here's how it's pictured in the patent application. Was it intentional or a mistake?

Hope it's ok to post this link. If not, maybe someone can figure out how to post the picture.

I'm aware of that pic. It really is a piss poor view on which way the spring pack is located. I doubt HD would file a patent with the springs mistakingly installed backwards since the two previous comp patents had them the other way. There is also a technical reason to run the heavier spring against the cam.

"they included liquimoly lube as the gold standard in the primary"! part # please!! YOU must mean the same old HD dyno oil (+) with the NEW STICKER on the outside!!

[Templer]

I hear the new primary has magic syn sawdust fluid in the whole motor. Quiet! Quiet!! Quiet!!! 
Note: works with ALL makes and models in rear ends,transmissions,blocks, and several other drive ailments: colds, cough.
Guaranteed to lighten you wallet!!!!
