1950's Fleetwin....

Re: 1950's Fleetwin....

Yes, when the lower shaft's internal spring is sprung, it expands, effectively lengthening the shaft. This results in it pushing upwards against the bottom of the waterpump plate, which is where you get the binding...

Chinewalker,
Thanks for the response!

I have located the part 2 different places online and a place locally. Price is around $20 give or take $5.

Can you tell me how I will know if the part is good or not when I purchase it or pull it from a donor outboard?

In the donor outboard, if the lower unit is good still I assume rotation of driveshaft will determine its quality but what if the lower pinion gear is tied up etc.

Thanks,
Chris

Re: 1950's Fleetwin....

All,
Maybe I should also ask the following to fully understand;

The functionality of the pinion shaft/shock/clutch assembly is to take a minor impact of the propellor into rock/other debris (extreme case) and to provide a connection between driveshaft and lower pinion gear assembly/propellor (normal).

So basically the propellor hits something and the top compared to bottom of shaft/shock/clutch assembly will rotate (clutch disengages) temporarily to avoid tearing up lower unit etc.

I believe chinewalker mentioned the above but wanted to verify...thanks!

So basically it must have hit something, more then likely, in its lifetime that caused the rotation but the clutch did not fully disengage causing the expansion/breakage internally? (and now the binding)

What I can see internally of this thing is the spring looks corroded...so this is probably some of the problem....maybe initially.

It appears this assembly was used in many outboards up into the 1960's. Is there any quick way to identify donor outboards. (i.e. horsepower from these years etc.)

I am guessing on a good pinion shaft/shock/clutch assembly I would not be able to rotatate it by hand....mine I cannot. Will it push down?...still trying to figure a good from a bad.

Thanks,
Chris

Re: 1950's Fleetwin....

All,
I found another Clutch (Pinion) Shaft out at the salvage yard. The first one I found was severely rusted....so I kept looking... finally found a clean one.

The shaft did not look much different then the old one. There may be a slight difference height wise but it is very close. Luckily I took the old one with me and tried it in the lower unit of the donor. Once the old shaft was all bolted in it bound. Got the donor part home and put it in mine and seems to be good....no binding.

Yesterday I received the new ignition system, carb kit, and seal kit....So hopefully this weekend I will try and get it all updated and put back together.

Will keep everyone posted on my progress,
Chris

Re: 1950's Fleetwin....

All,
Resealed the lower end, new igntion system (points,coil, condensor,plugs,wires, and caps), carb kit, pinion shaft, new impellor are all in place. I still need to grab about a foot of hose yet and replace also adding in a new small inline filter.

I used 3M-847 on lower unit....how long till I can use it in water (full set)?

I coated both surfaces with 3M-847 where used as directed....

Hoping I can start it up tomorrow after work....but want to make sure everything is cured.

Thanks,
Chris

Re: 1950's Fleetwin....

All,
Put the new hose in with inline filter.

Refilled lower unit with Hypoid Oil, connected fuel tank and primed, and put the outboard in the water tank.

I started it right up on first pull.

Ran it for about 15 minutes or so till I ran out of gas but before hand got it to idle real nice not to mention the high RPM.

It shifted fine and idle very decently. Was able to touch cylinder head during and after shutting engine down so I think its ready to roll....at least it can go on my boat for a test outing now.

Thanks everyone for the help!
