1957 35hp Evinrude Lark Help

[Squirrel42]

I did not drill into the gear case or even all the way through the brass bushing, so why the hell wont it pull. 59 years has got this sucker frozen to the gear case I guess. Everyone's videos make it look so simple and I am over here like WTF!
Murphy's law?

"Anything you try to fix will take longer and cost more than you thought"

I got all my gaskets and seals today, I could be done with this gear-case if I could just get this damn seal out.

 

[Squirrel42]

Turns out I ordered the wrong bypass gaskets or they sent me the incorrect gaskets.

I ordered part # 0304784 OMC gaskets. I got the gasket # from the 25532 Evinrude model diagram parts list.

Is the part # wrong? Or did they send me the wrong gasket.

finding a long bolt should not be a problem .... Lowes and the likes like of home depot..... have various size threaded rods 2 -4 feet long
just get the correct one for the job.

​ At get a 6 inch long or 8 inches piece of 1/2 inch galv. pipe & slide it down the rod.

close up the rod end with a fat 1 inch washers and two nuts. thread the rod in the bushing and slide the piece of pipe upwards to bang against the fat 1 inch washers in a hammer like fashion to pull the bushing out

It's threading deep enough but it wont budge, even tried putting a bolt in and slamming from the opposite side. nothing, wont budge. I said screw it and started working on my 5.5hp.. uhg, this is hell!

What about taking a small propane torch and heating the gear case around the bushing so it expanded a little? Maybe also soak it in some penetrant. You have to be careful with heat and aluminum. I would guess heating that area for 1 minute while moving the torch around the area continuously would be ok. Perhaps someone else will chime in to lend some confidence to this suggestion.

 

[Squirrel42]

I was worried about using heat, I have PB blaster soaking on it right now. I guess I'll try again in the morning, would love to get it done so i can move on.

I had some head bolts that were stuck on my 1955 Big Twin 25hp. I heated up the heads of the bolts so they would expand and contract to break free from the powerhead. I then heated the aluminum block while the bolts were cooling. I used a small bottle propane torch and kept it moving and didn't hold it on one place more than 5 seconds or so...kind of like drying your hair with a blow dryer. Worked no problem and I got the bolts out. I timed my "hair drying" so that I wouldn't go
over 1 minute. Took a few passes at it but it worked. Good luck.

Take a picture of the bushing. I have pulled thousands of them , and never had one stuck like that! I wonder if some strange owner before you used loc tite on it, or threaded it in? Not sure.

Racerone, I would like to see you do that one day! Not doubting you, you have been doing this much longer than me, but I just cannot imagine that being possible. Especially with the o ring compressed like they are.

I don't believe Frank makes that particular tool anymore, but you can ask him. I use a simply 5/16" rod, ground down on one end to 1/4". The taper is a couple inches long. But, if you already have a bolt threaded into the bushing, the easiest way for you now would be to just hit the bolt from the other side, to drive it out. It should drive out with a few sharp raps with a hammer and punch against that bolt. If not, someone did something funky in there.

 

[racerone]

Nothing to it mate ----These o-rings can be replaced without removing this bushing !!!

 

[Squirrel42]

Got a picture of that great tool you used to fish the o-ring? I see what you mean, that o-ring is taunting me.

Can you verify the Bypass gasket part #, I ordered part # 0304784 OMC gaskets. It's to big and now I'm left wondering what the hell to do?
Is there another part # for bypass gaskets for 35 Larks, Big Twins and Javs?

 

[racerone]

Far to many folks adhere to the " it can't be done " type of thinking.----Should not stand in the way of those doing it.----Just some pointy tools and some blunt tools and the o-ring is out and a new one is in !!!

 

[HighTrim]

No that is the correct part number, 304784. Post a pic of it, you may have gotten the wrong gasket. Where did you order from?

 

[Squirrel42]

No Title

Well the second gasket came today and it's wrong of course.. Part # 304784.. I got two pictures for you High Trim.. ordered from E-bay sold by spicersports.
Now I'm affriad to order anymore from anyone, should i try I-boats and order again?
Cant tell you how much i appreciate you, Racerone and crosbyman answering all my stupid questions. How do i buy you guys a round of beers?

 

[Squirrel42]

Comparing the pictures on e-bay and it all made since! This guy is selling incorrectly labeled gaskets. It's my fault i didn't insure that the picture was in fact the correct gasket. You live and you learn, off to I-boats to place another order!

 

[HighTrim]

I would imagine he would take it back no questions asked. He obviously made a mistake on his ad.

Not likely on purpose, was probably an honest mistake.

 

[Crosbyman]

if I help no need for beer.

I am just glad to help out as I was helped by everyone on this site. it is a great hobby

 

[Squirrel42]

Best hobby I have picked up by far, I failed at bushing removal and just took it to a marine shop 2min from my house. I'm having them just seal up the lower case for me and order a new bushing that I destroyed, this way i know it's sealed up correctly and done right.

Turns out everything looks great up in the ignition but the Spark leads are toast it turns out. Now I'm on the hunt for Copper core leads around town, looks like i might have to order them. Any good recommendations on buying them with boots and spring would be appreciated.

I have tractor supply stores, Napa and so forth in the area. I have seen people say they bought leads for an old ford and old tractor leads that have worked. As long as it's 7mm copper core am I good to go if I find them?

 

[lindy46]

7mm Copper core is correct. Usually sold by the foot.

Melted Coils??? Possible overheat or bad coils?

Ordered new spark plug leads, springs and boots, they should arrive by Saturday. Heavy rain chances means I'll have time to work on the motor some more.
Pulled the spark plug wires and decided to take everything apart for a deep clean, cant believe the coil is melted to the base. now I'm wondering whats next?

 

[Squirrel42]

So I've got the old Lark to fire up and run for about 30 seconds.. After that it will rev really high and just die, sometimes running for less and just sputtering out.
Is this some kind of fuel issue? Since it's running for a good amount of time can i rule out spark?

When i choke it and un choke a little bit of fuel spills from the carb, is this natural. Could running the engine without the muffler cause it to bog down and die?
