110 lifter failure, recommendations on RELIABLE build
« on: July 26, 2020, 09:44:21 PM »

The 110 has given it up after a measly 32k. Since it's got to come apart I want it put back together in a configuration that I don't want to have to worry about for about 60,000 miles at least. Can I get some recommendations on a good build that's reliable and makes good power and torque. I am thinking 117 build. What's opinions on gear drive cams, head work, etc...? The majority of the miles are highway at 80+. I also pull a trailer some times, so torque is important. I am rarely over 4k RPM so I don't need horsepower at super high rpm. It's a Road Glide Ultra so it's a heavy bike. It's a wet head so I know that creates some limitations.

I went with screamin eagle 117 kit with the redshift 587. Made sure the foundation was s&s flywheel. Lots of torque.

Haven't taken apart yet. It's above my abilities, so it will be going to S&S Speed Shop in metro East STL for the work. It's still running, just making a hell of a racket, so I hope it's not come completely apart and sent metal through the entire engine.

Generally the roller of the lifter fails.

My answer will be contrary to most but based on personal experience. You pull a trailer that changes things, long life will come from a valve train with relieved pressure/ loads, lower heat (compression & cylinder pressure down), and excellent ring seal.  What does it take to go there? A 113 from stock cylinders bored +.060. A cam with mild ramps and added exhaust duration. If 117 is on the plate, ok this is a full engine job, bored cases not the drop-in kits. Remember you said 60k reliable miles, that is where I am going. Compression on the conservative side. Heads need new guides and a good valve job plus dual springs that are lighter than stock. High quality lifters. Crank needs to be reworked at minimum,  an S&S crank, better. Use head fans to cool the engine.  Add a higher capacity clutch. Use the latest rev compensator.  Have a proper tune done. Consider a smaller front pulley to lower gearing.
The whole gamut of things the internet says that are needed, many are not and just oem parts will be fine. Lifters are a maintenance item still, 30k miles and gives a look at the cam chest then.

I hate to say but we've all been warned. I just did a complete build while I was thinking about lifters.  Crank too had to be replaced.  Good luck however you decide to go.  Stuart.

If one wanted to replace the lifters before a failure occurred what’s a good lifter to use with the stock cam and pushrods?

S&S which are basically the (now superseded) OE "B" lifters.

HD Street Performance, do you consider your replacement lifter the same quality as S&S? Who manufactures them?

The quality is equal. I would prefer not to reveal the source, they are made for us and I buy them manufacturer direct.
