After finding no real walkthrough to this simple process of converting a hydraulic roller lifter into a solid roller lifter for valvetrain measurement, I decided to type a write up with pictures, so let me know what you guys think
Tweezer / Forceps
Eyeglass Flathead Screwdrive
You can use a new lifter if you want, but since I am using stock replacement lifters, I just tore down one of my old ones in case anything went wrong, but you can use a new one and convert it back to a hydraulic lifter.
The pictures corresond with the steps
1. So start off by laying the lifter out that you plan to disassemble and cleaning all of the oil off of it.
2. Then use the small flathead screwdriver or the forceps to remove the clip that holds the lifter together. (do this carefully as you can bend the clip as well as the possiblity of it flying out and you never finding it.)
3. Remove the top part of the lifter that the pushrod rides on by simply inserting the forceps into the hole and expanding the tips so as to grip the the oil hole and pull it out. This can also be done with a small scredriver.
4. Use the forceps to remove the plunger as well by expanding them within the hollow part of it and pull the plunger out of the top of the lifter.
5. Use the forceps to remove the spring from the lifter and lay the parts out in front of you. *I took the time to clean all the oil off of the lifter assembly so I could move them around and store them without creating a mess.
6. Turn the plunger around and insert it backwards into the lifter without the spring so the nipple that the spring would normally sit on is facing upward where the pushrod sits.
7. Next, insert the remaining piece where the pushrod sits into the lifter the way it would normally go and push is down as much as possible.
8. Lastly, using the forceps, insert the clip so that the bottom of the "U" shape is tucked in first, leaving you to simply tuck the two small tabs at the top of the "U" in under the lip of the lifter assembly.
Now you have a solid lifter for use in measuring valvetrain geometry such as PTV clearance and pushrod length
