Re: [PSUBS-MAILIST] Kittredge Motor Housing help

Ain't that linkage a piece of work? Yikes! And there is so much flex in it that the motor literally bounces against the long rod. The thing is nearly impossible to steer, and mine was worse, being a K-350 single short body. That crap has GOT to go, Jon!

Jon,

 

See if this has any merit: 

1. Remove the mesh around the braces and wrap a length of chain around the juncture of the braces and the head. 

2.  Run a bolt through the link at one end of the chain and the link closest to it coming from the other direction.  The links would be facing each other like this:  / \   and the bolt would go through them like this: -/-\-  .

3.  Tighten the bolt to tighten the chain.  With ten braces the load should be spread out enough to bear the load without damage.

4.  Wrap the tail of the chain around a lever (iron bar, oak 2x4, whatever) to turn the assembly.

 

If the hook at the end of the chain falls at the right position, you may be able to dispense with the bolt, wrap the chain around twice and go for it.  This might work or it might be a worthy of discard.

 

Good luck!

Jim

There's enough room for two people opposite each other, but I'm not sure
there's room for two chains.  The area where the chains would be placed
on the tank head is pretty narrow.

Vance:
I called four "tool" rental places and none of them had a chain wrench. 
I haven't even seen any available online for the size I'd need.  Most of
the strap and chain wrenches I see are for small pipe like up to 3
inches.  The rear motor is in an 8inch diameter cylinder.  It's one of
those specialty tools I'm going to have to find from a friend, of a
friend, of a friend, I think.

Dan:
Swapping over to Minn-Kotas is definitely an option, but would be
relatively expensive.  I think the 100lb thrusters are hovering around
$1k now and I'd want at least one of them.  I found a replacement online
for the mechanical seal and if the motors still work I will probably use
them before swapping over.  From a functional perspective, I might as
well use them until they fail.
