A couple of questions that I have been unable to find the answers to...

Installing TW26 cams on FLHPI

1) Do I need to drain the oil?

2) Will I need to disassemble the lifters and soak them in oil...or can I leave them in the tappet block and not worry about them

No need to change oil and if you have low miles you can use your lifters. The lifters can be held in the bore with a magnet set using cloths pins or clips made from binders. the service manual shows how to make the clips.

Clips

Checked out the service manual showing clips used on lifters. How does that keep them from falling out of the bottom into the cam chest?

Pushes lifter aginst side of bore. Clearance tolerance does the rest.
Best to remove and....
Mark which lifter came out of which bore.
Look over your lifters for signs of galling, scoring on sides, roller. Check for seized plungers.

Don't need to drain oil, you will lose about 8 oz., place a pan under the right side. Disconnect the battery for safety.
Pull the lifters out of their bores and mark them and lay them on a clean shop rag. DO NOT disassemble the lifter bodies. After you get it all reassembled get some decent pipes

When I put my cams in, I had pulled the lfter blocks. I put an o-ring around the tops of each lifter and that held them up and out of the way while the change took place.

Don't forget you can install them 180deg. out. The oil hole on the side faces in on all lifters.

2 most excellent and critical notes here....The o-rings to hold the lifters up out of the way is an excellent idea, Thanks....and the fact that the lifter oiling holes must face in is absolutely critical....

I replace the lifters exactly as I find them , the oil holes are usually facing out, at least that is how they are from the factory. I really don't think it matters tho, correct me here if I am wrong.

Doesn't matter. Oil passage goes 1/2 way around the bore.
