help pulling a bearing Carrier and resealing lower unit.

[SigSaurP229]

My manual says to thread to long bolts 1/4 by 20 bolts into bearing carrier put a puller on them and tension. Now I have two long threaded rods 1/4x 20 and the threads keep pulling out. However the 4 bolts I pulled out of the lower have a 1/4x 28 thread pattern and looking at the schematics it makes no sense what the manual says to do as the carrier retainer sits behind the snap rings There is no place to lock a jaw puller so how do I get this thing out? I am stumped.

1972 evinrude 65 hp hydro electric drive.

I am resealing the whole thing as I have gotten water in the foot, most of the seals look good with the exception of the 4 o-rings that go on the bearing carrier bolts but I ordered all of the seals and just decided to do the whole thing. Appears to be a fresh water motor but the thrust washer was stuck on the prop shaft. (No grooving).

Sig;

When you say "the four bolts you removed from the lower", do you mean the ones that hold the lower unit in place or the four for the carrier.

If you have a tap and die set, they usually have A TPI gauge in them and you can see what TPI the threads are on the carrier bolts.

Whatever the tpi is on the carrier bolts, you should be able to get rod to fit that to pull the carrier out after removing the circlips.

This diagram of the LU shows the circlips but oddly enough, they don't mention them in the numerical list.

My manual also said 1/4 x 20 but the actual bolts were 10 x 28 or similar. The OEM manual was wrong in this case (very rare). I made a homemade puller for mine. I got a piece of threaded dowel from Lowes and cut a couple of pieces about 8-10 inches long. I screwed those into the gearcase head holes. Then I used a flat piece of metal that I had laying around. I forget what that metal came from but it had two holes for the threaded dowels and a threaded hole in the middle. So this flat piece of metal saddled over the prop shaft with the threaded dowels protuding through it near the ends. I put washers/nuts on the threaded dowels. Then I put a bolt into the center threaded hole that lined up with the center of the prop shaft. By turning in the bolt, the threaded dowels pulled the gearcase head. I remember that the head was really stuck; I thought that the dowels would break, but it all worked out. Hope this makes sense.

Has this motor been in salt water. If it has, you may need to apply heat to the casing to help the carrier out.

Yeah the bolts that I pulled out were 1/4" by 28 thread pattern. My intention was the same as yours but I couldn't find any threaded rod in 1/4 x 28 so I got 1/4 X 20 and jammed it in by three turns but it wouldn't hold (Hoping I didn't mess up the retaining plate) if so its only $25.00 but still. So I have another option that I am going to try in the morning the carrier kind of has V pattern in the upper part of the carrier so I got some threaded rod 3/8" large washers and nuts my intent is to hold fastner the rod through the back side of the ridges in the carrier then I will thread the rod onto a harmonic balancer puller and let the puller do the rest.


I believe this to be a no salt motor+
