flip clutch dog?

[redcat]

Hi all

I have a 1953 15hp fastwin with a bad clutch dog. I have heard that it can be flipped around and the problem put in the reverse side (which I use rarely) and the forward will be good to go. Sounds like a plan if this is accuate information. It would save me a few hundred in parts. The Motor runs like a bear but I can only run about quarter throttle when it starts bumping. Any help is greatly appriciated.......Thanks in advance

Ron

Re: flip clutch dog?

it is a bandaid. the gear is already damaged, all it will do is damage the other side of the dog. i am not sure if that particular motor can be turned around.

A few hundred in parts??? Post a want on aomci.org in the webvertise section and see if someone has a spare set for sale (almost guaranteed you will find something), do it right as you have to take it apart to flip the dog anyways, as TD said , it's a band-aid.

I just took apart my 6hp lower, I'm not sure if its the same type or not, but it looks like you could. Mine shows some wear on the forward side. I'm thinking about flipping it just to get as much life as I can out of it.

Why fix something wrong several times when you can fix it right once?

Re: flip clutch dog?

well, his engine is 57 years old.

I'm almost positive he is running the engine his budget allows.
Having said that;

SHIFTER,Clutch dog $111.40 USD

Ooooor just not have reverse. I would spring for the no (or limited) reverse.

...unless he perfectly restored this thing and it is near mint, then buy a new one!

Would it damage the gear? here is my slightly worn CD, the gear looks ok though:

Hey, he said his is jumping at 1/4 throttle. With all that banging around, you can almost guarantee the gear is worn out. The shift linkage may be beat to death too. Anything else is wishful thinking.

BigB, I see nothing wrong with yours.

thats just a boat buck
better to fix it right than paddle back to the dock(if he can afford oars)

Re: flip clutch dog?

The OP can have his gears "cut," if that has not already been done in the past.

I agree that reversing the CD is a bandaid fix. I would replace it and get the gears cut. For those that are not familiar with this, look at the photo of the gear, above. A machine shop can cut the tabbed faces in the center of the gear, giving them a clean edge. This is not something to try at home - you have to know what you are doing and you have to have the correct equipment. That said, it works well and is a great deal less expensive than buying new gears.

Has anyone checked to make sure the shift linkage was properly adjusted before the tear down? I have seen many lower units unnecessarily torn down, on count of improperly adjusted shift linkages.

from what I see in the pics, the parts don't look too bad. What is the clearance in the shift cradle and clutch dog?

Re: flip clutch dog?

my 35hp had the same problem. had to replace both the clutch dog and the foward gear. even if its just slightly worn out it will jump out.

my 10hp had a shift rod problem. my screw that hold the 2 rods together was severly striped therefore letting it come out of gear. a big bang!

if the clutch and gear start to shine on the ends of contact then it defiantely needs to be replaced.

Re: flip clutch dog?

Well, if you're under .007 in the gap and there isn't any grooves, then they should be safe to re-use. The trick is to set the shift linkage to where it is fully engaged in forward gear and tighten the two clamping bolts down on the shifter, then put it in neutral and make sure it disengages. I've had to reset these things a lot in the past on many different motors. It's as common as needing to replace coils and spark plugs in these things. Even when some one removes the shift rod from the coupler and reconnects it, that will even change the way the dog engages in the forward gear. It only takes .010 difference in the shift linkage length,to effect the way it engages or kicks out of gear. If you do see grooves forming, then you can flip the shift cradle/clutch dog over and get more use out of it, but then reverse won't engage fully. Of course, that won't matter, because you won't go above a fast idle when reverse is engaged anyhow.

The best way to do this, is loosen the two clamping bolts on the shifter and remove the obround cover on the leg. Take a needle nose plier and pull the shift rod up to where forward is fully engaged. Then clamp the two bolts on the shifter down and you got it. It's that simple. Once you got the bolts clamped down, put the shifter in neutral and see that it disengages right.

Just my two cents to help prevent extra work.
