Oh yeah, seal pullers should be at any auto store for about $5-$10. They're basically just a handle with a hook on the end that lets you lever the seals out of place. Here's a pic.

I also have the use of my dental hygiene tools that come in handy in odd situations

A really good thing to have because I had to use a dental pick to get some very hard crud out of the low-speed carb jet on my 1959 Johnson 35 that somehow survived three overnight soakings in cleaner. Hang in there, I know you can do this!

Hahaha! I just changed my profile pic to one with my daughter...so can't say people aren't forewarned that not only am I blonde...I created another one to mess up the world as we know it!

Re: '56 Johnson Javelin Shift/Throttle problem


The seal replacement kit is here. I've attached a photo of everything laid out and labeled with letters...can someone please help me identify where everything is supposed to go? I know that "F" are the ones that go on the drain and vent screws for the gear oil. I don't want to tackle this until I know exactly what I'm doing! Thanks!!

Re: '56 Johnson Javelin Shift/Throttle problem

Great news, you got those fast! I recommend you print a copy of the parts diagram at the link below if you have not done so previously. Pictures really help me but I'm old. Member kfa4303 identified everything but the large o-ring in his description in post #70 of this thread, so use that info. I will also take a stab at it also using the parts diagram reference numbers and my own descriptions.

http://www.marineengine.com/parts/v...ntage-evinrude-johnson/376750/37675000001.htm

A. Ref.# 8 - Driveshaft seal under the water pump
B. Ref.#37 - Propshaft seal inside "housing" #38
C. Ref.#39 - Large o-ring outside "housing" #38
D. Ref.#16 - String seal for gearcase halves
E. Ref.#46 - Small, thick o-ring on shift rod above bushing #45
F. Ref.#12 - Washers for drain and fill screws
G. Ref.#47 - Small, thin o-ring for top of driveshaft below the splines (See EDIT)
H. Ref.#?? - Very small o-ring for shift yoke pivot screw #32

I hope other members will post and correct my errors. Good luck!

EDIT: This looks funny and not like an o-ring. Is it flat?

Re: '56 Johnson Javelin Shift/Throttle problem

Thanks!! Yes "G" is a flat hard plastic washer type. I'll print that out and start later this afternoon/evening. Safe travels to you, my friend and "Go NAVY!!!"

Re: '56 Johnson Javelin Shift/Throttle problem

Lookin' good Kathy. Willy's got you all straightened out. I'm not sure what "G" is either. May be and etra piece for a slightly different model. Good luck. Take you time and holler if you get stuck.

Re: '56 Johnson Javelin Shift/Throttle problem

So "D" wasn't a Twizzler candy? Dang!

Re: '56 Johnson Javelin Shift/Throttle problem

nope...no snacks included in the kit! but that wouldnt be a bad idea!! when you are ready to install the twizzler, soak it in hot water, and leave a lil bit extra on both ends when you trim it.....as there will be some shrinkage when you bolt the gearcase sections back together.

Re: '56 Johnson Javelin Shift/Throttle problem

Yes "G" is a flat hard plastic washer type.

All right, here's my best shot. I believe "G" is for the pivot pin screw because the parts catalog shows that as #31 in the diagram and the description is "washer". That would make "H" the o-ring for the top of the driveshaft. You need do do some checking before you take that to the bank. Sorry for the confusion!

Re: '56 Johnson Javelin Shift/Throttle problem

Here's my best guess after looking again.

 

[HighTrim]

Re: '56 Johnson Javelin Shift/Throttle problem

Where did you get your kit from?

H is the o ring for the pivot screw due to its small ID. There is no way that would fit the driveshaft OD...look at the ID compared to the driveshaft seal ID.

I cannot see anything that resembles the drive shaft o ring. I can fire one in the mail for you if you need one.

Re: '56 Johnson Javelin Shift/Throttle problem

Just like the tip above from member nwcove regarding the string seal, I need to give you a head-up about the o-ring at the top of the driveshaft. Because it must pass over the splines during installation, you should wrap the splines with masking tape first to prevent the sharp spline edges from cutting the o-ring. Details, it's always about the details.

I apologize for the link I posted not being the lower unit/gearcase assembly page for all my references in the parts catalog. When I copy and paste the needed page, it still only links to the first page. Electro-magnetic forces beyond my comprehension!

Re: '56 Johnson Javelin Shift/Throttle problem

Wow! What great responses from everyone! Glad nwcove has my "snacks" sense of humor too! Great hint about soaking that in hot water first to make it pliable, will do. Interesting about the mystery part "G". I really don't think it would be the pivot screw washer..too big and not flexible enough to create any kind of effective seal there, I believe that "H" is more the correct size, as High Trim suggested. I got the kit from Sierra. Since I replaced the impeller first, I changed out the drive shaft O ring at that time (took the old one to the hardware store and they matched it up with one in the plumbing section.) Should I use the one I already installed and keep this as an extra or use the one that came with the kit to be 100% sure? I didn't know to wrap the splines with anything first to prevent it cutting up the O ring and I don't think it did any damage but that is a very good hint if I change it out again! Interesting fact is that there were absolutely NO washers on the vent/drain screws or on the pivot screw when I took them out. Kinda think I know what happened to the gear oil! Can they just dissolve over time or do you think the PO didn't reinstall them at some point?

Re: '56 Johnson Javelin Shift/Throttle problem

Your o ring is fine, just leave it as is.

The previous owner left them out. Leaving out the o ring will leave you with a stuck driveshaft. It keeps water out of your powerhead.

Same thing applies to the driveshaft oil seal under the water pump. The propshaft oil seal should be okay since it does not have splines.

Thanks to HighTrim for keeping us in the middle of the channel. That's the beauty of the forum, we all keep learning everyday!

Re: '56 Johnson Javelin Shift/Throttle problem

Have started the surgery...replaced propshaft bearing O ring quite simply but kinda stuck on the next one, the Propshaft seal (B) in the diagram of parts above. I'm not quite sure where this is supposed to go..does it go inside of the "housing" for the part I just put the O ring on? If so, how do I get the old one out of the housing and what's the bronze colored metal inside of the prop shaft seal? Do I take it out of the old one and put it in the new one too? Sorry for being so stupid on this part, I know I must be making it harder than it is but the replacement part doesn't look like the old part and I'm not about to force anything and break it. My only other thought is does this p.s. seal go inside of the next piece on the shaft, the one that has bearings in it? I'm posting pics of both sides of the new part next to both sides of the housing and also of where things are on the transmission at this point with this part removed, showing the part with the bearings. (there is notable rust on one of the gears, I put an arrow on the pic, does that matter?) Thank you! I'll work on something else while I await your words of wisdom!
