Hydraulic lifter install question
I have a 2010 Ultra with the TC 96 motor. After 70K miles I am replacing the lifters. The Harley Manual says to install them with the oil holes facing inwards, however, the lifters were installed at the factory with the oil holes facing outwards...Do I go with the instructions in the manual or do I install them they way they were installed from the factory? Any Ideas??
Thank You.

I noticed the same thing with my bike when I did the big bore this winter. I don't think it will matter. The oil flows around that slot and will enter the lifter no matter which way the hole faces. Just for no other reason than the manual said it, I put my new ones in with the hole inboard. They work just fine.

If you have the engine apart for some reason and are reinstalling the existing lifters, it's good practice to put things back together so they are in the same place and turn the same direction as before. If you're installing new lifters, it would make zero difference which way the roller turned.

I have read Johnson Hi Lifts are supposed to be some of the best.
I have them in my bike with a 530 lift.
They are working............so far.

Comp Cams V Thunder lifters are low priced and high quality. I use them and no noise, no clatter on start up, even after sitting for 4-5 months, and work great. Does not matter where the hole faces.

Go on u-tube, see if you can find a video concerning this. My 2011service manual says to install lifters in the bore with oil holes on the inboard side and the flats on the lifters facing forward and rearward. I saw a video while back addressing that the push rod cannot be under pressure and must spin freely on the lifter otherwise something is wrong and you risk a bent valve.

Pushrod thread count and the lifter and type you are using.
What am i talking about?
Different vendors have different pitch threads, so you cannot assume what HD says in a book for "their " adjustable push rods to be correct for what you are using.
You may have to measure how much your pushrod turns out per flat
You aso have to know what lifters are in there . Most want the piston centered, Johnson Hi Lift does not., solids want a fudge play or clearance.
