While taking the bottom end apart, prepping for a cam change, my rear lifters got disoriented. Which way do the holes go...same as the front one's...holes toward the cam plate?
I put new ones in and the ones that came out (factory installed) were opposite of what the manual called for.Geezer-Glide said:There may be a wear factor to consider, but as far as the holes go, as long as they ain't plugged up it doesn't matter. Mine were different front and rear.
AFAIK roller lifters do not need to be replaced as there is no wear pattern established between the cam and the roller. If money is not an object, use the 'B' lifters as they are considered to be better than the previous HD version.ride4daze said:Not meaning to hijack this thread, but are you going to use your old lifters on new cams? I have a low milage bike and was wondering if the lifters would have to be replaced if I changed to gear drive cams. I have no experince with roller lifters. :dunno:

Hmmmm..... they must have changed they way they write the books now. I am looking at the manual for my Dyna (you didn't state in your first post that your bike was a TC,) and it says "The orientation of the oil hole in the side of the lifter does not affect lifter performance". Guess they left that part out in the new manuals. Time for a revision....prophet said:Actually the factory manual doesn't tell you. It just says to put them back the way they came out ...or you could cause severe injury or death :wacko: ...not to worry, the cams are in and the bike is rockin! Mucho increaso down in the 2800 rpm range. The Woods TW-6 hits hard and pulls all the way out to 110 mph (I didn't venture further although there was room on the throttle...it's still winter and cold out here). Good recommendation HDWRENCH!
I don't think so. Whenever they got swapped, it wasn't an accident at the factory. Either it was intentional, or there has been someone in there before you.Turns out that the exhaust push rod (black) is 10.536" long
Intake push rod (silver) is 10.418" long.
My rear cylinder push rods were in backwards from the factory.
The 118 thou difference was absorbed by the lifters untill a little wear set in (35000 miles)
Then the slight intermittent top end ticking started.
