It's a Little too Late Another Failed Lifter
« on: November 19, 2011, 09:06:31 PM »
I was going to put new lifters in over the winter for PM. This is my 09 FLHX “110 KIT” (was 96”) with Woods 7H cams, roller rockers, SEPST  Rinehart slip-ons, with 35,000 miles……ah well "it's a little too late"!! :(
I lost a lifter and it took out a cam. There are a few threads out on this topic right now so I figured I’d share mine.
I ride 2 up 75% and loaded tour pack included. 25% solo no tour pack with and put on 10,000+ miles per year.
Plan#1 replace lifters with Woods directional and cams.
Plan #2 is head work, pistons, TB reworked. The head porter suggested S&S 585 cams. I’m leaning towards plan #2. Any input on cam choice would be appreciated. :-\

What brand lifters?
What does your oil pump look like?

Stock original lifters that came in the 96".... that's why I was going to replace. Pump looks to be ok. If I go with plan 2 I would consider replacing the pump too. Thanks for the response.

What heads does your kit have? MVA? ACR?

OK
Lifter failures have occurred with the 110 using stock lifters. The S&S 585 has what I would call industrial motor ramps and would certainly ease the accelerated load on the roller. That said the Wood cam will perform much better and responsive in that motor.
Is yours failing with the axle pin internally or the outer part of the roller?

If it were mine I would buy a set of Wood lifters, a rigid Smiths Bros pushrod set, and install AV&V 160# beehives. Headwork would just be an option to correct the guides in those heads that are fit too loose (stem clearance) and as a small performance enhancement.
IME the 585 is a soggy runner in a 110, the 570 not a real barn burner either but YMMV and the compression, pipe and tune will have a large influence on the outcome.

Thanks for the response...The outter part of the roller looks to have been skating on the cam lobe.
You don't recommend the 585 what would you recommend with head work and a bump in compression, pistons and TB reworked?

We've seen the 585's hit hard off the bottom in the 107"ers we've used them in. :)

I really like my S&S 585 Cams but that is not to say there aren't better ones out there and it should be noted that mine are in a Dyna , not a bagger !

Link to a dyno sheet with some S&S cams. The sheet is from S&S so take that in consideration.

OldLefty, I saw your thread when I did a search on the S&S 585. Thanks! I won't speak with my head porter until after the holiday. I just wanted to get some suggestions and or opinions on a cam choices for my riding style. Thanks again.

See the harley dealers were right using synthetic would cause parts to skate because it's too slippery

Several cams come to mind but if the TB and compression plus headwork is done I would use one of many but a few high on the list would be a Wood TW8 or TW400, Crane 296, or Tman 625. The decision would be based on riding style and payload.

Riding style as mentioned is 75% 2 up with tour pac......75-85mph on the highway. A few road trips per year. 25% solo no t-pac I like to wind it up a bit too. I was showing 105hp/120tq before alittle more is expected with heads TB and different cams. Here.s my current dyno sheet again although many say its not for real!!!!

Woods has a nice little cam the TW777 for this motor, that and his lifters plus a good motor oil system flush would get you going again. The heads and TB would just take you up the ladder from there. These lifter failures seem to be happening more often and if that trend continues I will change all CVO heads to Beehive springs and lower the pressure a bit. Pistons become essential at some point to raise the compression. It isn't hard to get over 120/120 with a very respectable torque curve and those cams I mentioned previously then come into play.
