Make sure the pin on the front (forward gear) bearing is sitting right in the hole. Often times these get mis-aligned and the skeg gets sicnhed down on it. Item 45 in the attachment will have a hole to line up with a dowel pin, in the gearcase where it sits.


The diagram is post number 14 and the bearing is item 45

On page 12, item 45 is the bearing. I think you are looking at the wrong pin. Under #45 there is a very small pin that stops #45 the bearing from spinning and lines up the oil channels.

Well I placed the pin in the wrong place, that makes sense. Did anyone catch that from my picture link? The diagram shows the pin in the drive shaft, does it slide through the bearing and into the shaft as well?

There's two pins and they are unrelated. One is at the bottom of the shift cradle (bigger) and there's a very small one below the front bearing. The parts manual does not show them well. Pull the front bearing out and look below it and/or post a pic of it.

No, it only sticks out about 1/16 of an inch, which is enough to keep that bearing cap from spinning.

Don't worry about 47, it's easy to put in at the end. Lift up 45 and check to see if the pin is protruding at all. Then look carefully at the bearing and you will see the grove it fits in. It is very important that they line up or the bearing will not get oil and seize during use. And it has happened to me, so it's not hearsay.

45 doesn't move. I cannot "lift it". Are you under the impression I have the whole gear case taken off? I only removed the lower part of the skeg. 6 screws and it came off with some wiggling.

The only pin that I have had an issue with is the one that is in the photo I took that is in part 47. Is that where is belongs? If not where did it come from?

Re: 1958 QD-19 Johnson 10HP cracked lower end help! Freeze Damage.

Hmmm. Ok, so what you're saying is that you did not remove the propeller shaft with the gears on it at all. Usually they come out pretty easy, I'm surprised yours is still in there with it being vertical. Most folks remove the entire lower unit from the engine before working on it and then turn it upside down and work on it from there. But as you were only doing the skeg, I guess your way will work. Normally you would remove the prop shaft to do any work in there. As you did not remove yours you have 2 options. One, put it back together and hope it was always the right way or two, pull the prop shaft off and inspect the entire thing and make sure it is put together right. I would do 2 if I was you and most will probably agree.

Now that I think about it I believe you said you tried to put it back together and it would not go? If this is the case the prop shaft might have shifted on you and you now have to remove it and realign it up. Are you sure the prop shaft never moved?

Re: 1958 QD-19 Johnson 10HP cracked lower end help! Freeze Damage.

You got it, now we're on the same page. The only reason I took the skeg off was to patch a crack from water freezing inside. While I was removing the skeg that pin fell out and I did not know where to place it, I still don't to be honest. The reason why I could not get the skeg on was due to where I placed the pin in the shift lever (47). I'm assuming it doesn't belong there as it stops me from getting the skeg back on. When I remove the pin the skeg goes on fine. Do you know what this pin is called and where it goes?

try the diagrams at marineengine.com...simple to navigate site that will have diagrams of your motor's components...in reality, removing the lower unit and inverting it may be your best bet to reassembly, I'd also suggest to you that you consider replacing the seals including the shift shaft seal at this time...I worked on a '59 10 hp. and would have saved at least one disassembly had I done the seals when I replaced the pinion gear..if there seems to be rust on your gear teeth, I'd definitely do the seals

Re: 1958 QD-19 Johnson 10HP cracked lower end help! Freeze Damage.

Hi bigjo. Try dropping the whole LU. I've circled the bolts you want to remove to allow it to come off. You'll also need to remove the lower bolt in the sift rod connector. Just remove the little oval plate on the side of the exhaust housing. Once the entire LU is off it will be much easier to work on. It should come off with the drive shaft and lower shift rod, but the copper water uptake tube should remain attached to the underside of the power head. Here are some links that can walk you through the job and give you an idea of what to expect.

Holler if you get stuck.

If I drop the lower end, where does that pin go I took a photo of?

Re: 1958 QD-19 Johnson 10HP cracked lower end help! Freeze Damage.

It is difficult (I find) to reseal/replace the skeg without first removing the gearcase and flipping it upside down. Im guessing the prop shaft shift/dropped and the pin is no longer lined up with the bearing cap, not allowing the skeg assembly to seat.

The pin is completely out. It fell out while I was trying to remove the skeg. Where is there a diagram of where this pin goes?

Big Jo, I have a feeling that what we are talking about and what you are talking about are not the same thing.

You are talking about the pivot pin, what you pictured.

We are talking about the pin that holds the bearing cap. Completely different things.

Ill post a video for you.

Ok, so 38 screws into the skeg and through 47. This I get - Pic

48 (Pin) is intact and has never moved. Pic

I placed the pin that fell out on 47 just to show it. Pic
