Re: lu seal kit, johnson cd 13

cant find a part# on the housing Chris, but i did get a caliper today, and the old seal does measure 0.937, so i guess its the same issue that RJB ran into. will have to order 314167.

NW,
The newer one I had didn't have a part number cast into it either (the old one does).

One of the things that gave me the clue to search for a different seal when the old style seal didn't work was remembering what I had found out when I had initially broken the original old style bearing housing, and was looking for a replacement.
I had punched in the old style housing part number to Marineengine.com's website, and it showed me that old housing part number superseded to the newer housing part number (both of which are NLA now..).

The newer style housing I had was on a spare leg I had up at the camp in Maine. I could tell right off the bat that it was cast a little bit beefier than the old style housing was, and also noticed that the original seal installed looked different too.
Of course the rest is history... At least some good came from my troubles last July... :)

hi racz, are you talking about the shift rod o-ring, or the driveshaft and prop shaft seals? or both?

heres a link from rogersjetboat that covers the whole job

racz,

Not sure what happened, but looks like the link that NW posted isn't bringing you to the right place.
Try this out; http://forums.iboats.com/johnson-evinrude-outboards/1956-evinrude-fleetwin-freshen-up-552803-3.html

It's the first post on that page.

My disclaimer to you though is: that's how I replaced it. I ended up destroying the brass bushing to access the shift shaft O-ring. My brass bushing was well worn, and a replacement was cheap enough, so it didn't much matter to me. Others have methods of removing that brass bushing so you can re-use it when you're done. If you want to go that route, you may want to do a little search of the forums to see if you can find out how, or even better, you can start you're own thread asking about it.

I dont think I have ever needed to replace the bushing, and have done hundreds. Remember all it does is hold the shift rod o ring and compress it slightly. A little 3M 847 around the circ of it will quickly fix any possible leaks, but water will much more easily pass through the shift rod/oring contact area than past the bushing/casting mating surface.

The easist way to remove it is to simply purchase the correct tool. PM F_R on this forum, he fabricates them.

Here is my original tool I made out of 5/16" rod, tapered down to 1/4". Basic but it worked for a few years.

Then simply drive it out. They do not all drive out the same way.

When reinstalling, do not allow the bushing to get countersunk in the cavity or it will overcompress the oring, causing water intrusion.

HT,
The biggest reason I decided to replace the bushing in mine was because the opening for the shift rod was pretty well egg shaped. It probably would have worked fine, but my major concern was if the shift rod had enough deflection, it could potentially push unevenly on the O-ring, and allow a little water past. Just a piece of mind thing, since it was the second time I was re-sealing that lower. ;)

Better safe than sorry right RJB! Totally understand that.

Tim, is it tight in neutral at all as well or simply in gear?

spins free and smooth in neutral, binding bad in fwd and rev. just washed the gear oil off my hands trying to see whats up with this one, everything turns smooth until i tighten down the bottom gc half?

Are you positive the alignment pins were inserted into the hole in the bearings?

Re: lu seal kit, johnson cd 13

the front bearing "should" be on the alignment pin, and the rear bearing has no pin, just the tab that is turned and up against the stop. is that the correct orientation??

Re: lu seal kit, johnson cd 13

well, im lost on this one. front bearing is on the pin, rear bearing (prop end) has the tab, which is oriented straight up toward the powerhead. buttoned it up and filled with oil for the third time, and it still feels rough in either gear. definitely can feel the gears meshing while turning the prop shaft or driveshaft.

Well I dont know either. If it was in neutral as well, Id say investigate the shock absorber, or even the bearings as you said this one had water damage in it, but only when in gear is odd.

Re: lu seal kit, johnson cd 13

the gear set all looks in perfect condition, the apparent water damage was only to the bottom of the shift lever..pitted, and the pin..dust. ( thanks again for the pin!). bearings turn smoothly, no lateral play. it just seems to go south when i tighten up the bottom gearcase half. hope i can avoid destroying a lu!
