Items needed:

Port sleeves, Pineapples inserts, Loctite "RED", an awl(or something to scratch with),

a piece of wet/dry 400 grit paper, a 1/8" punch, a hammer, a couple of clean rags, carburetor cleaner,

a cleaning brush, a vise.



First you will clean the inserts and sleeves; for the sleeves you want to use the cleaning brush

to make sure that all deposits ate scrubbed clean. Use the carburetor cleaner as your solvent,

it works VERY well.



Set the vise up with about 3/4" - 1" gap in the jaws, you need somewhere for the pin to go.



Next, you'll use one of the rags to protect the sleeve from the edges of the vise jaws.



This is the insert by itself; it is machined to .001" tolerance



This is the sleeve and the insert, ready for modification



Here you see the sleeve supported by the vise, cushioned by the rag, with a gap for the pin to fall into.



You wont have to hit the pin hard at all, just a couple of gentle taps should do it.

NOTE: you will drive the pin out with the port opening side of the sleeve up. Also note the orientation of the pin.



The pin comming out through the bottom of sleeve.



Score/scratch up the areas that will have most contact with the insert, lightly sand

to debur, spray with carb. cleaner, making sure that all surfaces are clean.



Remember, the inserts are made to exacting specs.(+/- .001"), so if they dont slide in chances are theres a

bur or debris that you missed. It doesn't hurt to lightly sand the inside surfaces to loosen any residue that

you may have missed the first time.

 

This is where, and how much Loctite I applied to the inside of my sleeves where the inserts will come to rest.



The inserts pushed all the way down into the end of the sleeve.



The inserts fit quite nicely in the sleeves.



When replacing the pin, remember the orientation that I told you to remember; this is where

it comes in handy. The SMALL end of the pin goes in first, then the fat lip is pushed back into the sleeve, then punched down to just below the surface.



Using the same punch that you used to tap out the pin now tap it in. Both ends of the pin will

be BELOW the surface of the sleeve



The pin has been properly seated when you feel a small indention over the pin on both sides of the pin.



Using the punch, a cold chisel, or large screw driver, peen the edges of the sleeve opening in,

to secure the insert mechanically.



This is a close up so you can actually see the SLIGHTLY peened in edges, securely locating the insert.





Taaa Daaaa! you're done.

Approximate time to complete BOTH sleeves: 20 mins...



You can see a pro do it in a video here

 

Thanks. It's a great write up with pictures. Helps people like me who just look at the pictures.

 

They actually show how to install these on video if you go to rebuildingrotaryengines.com or something similar. Pineapple Racing does the vids so there's a link from their site I would bet.

 

great write up, so people will understand these things work well

 

Great job! The hard part is getting the sleeves out and back in. Well, not hard, but tedious (especially if you find broken vac hoses, leaking fuel pd, broken oil injector hoses, etc. under the intake manifold).

 

...my advantage is I am putting in a fresh motor at the same time. Inserts are ready and waiting for the installation date...
