Stus-List hydraulic ram backstay

[CHARLES SCHEAFFER via CnC-List]

Hey guys,
Just wanted to confess something that went wrong and I'm still learning.  Had a 
major "fail" today trying to rebuild a hydraulic ram for my backstay. Moral of 
the story: take it to a qualified service company.

Background:
My local hydraulic repair shop that rebuilt my ram fifteen years ago, was very 
busy, short workers, and needed three or four weeks before getting to look at 
my leaking ram.  A friend of mine said I might be able to replace the seals 
myself.  I checked YouTube and learned a few tricks and found the drawings and 
operation manual for Navtec rams, ordered the seal kit online and carefully 
disassembled the ram and installed the new seals, o-rings, bearings, etc but 
hit a wall trying to put it all back together.   I couldn't get one of the 
seals onto the piston and I couldn't get that whole assembly to go into the 
cylinder.  It takes special tools and skills, I don't have.

Good news:  I took my kit to my local repair shop today, and explained my 
problem, and they looked it over, said most of it looked good, but I nicked one 
of the seals, and feeling sorry for me, they ordered me a new part, and put me 
ahead on their schedule.

I hate having systems on my boat I can't service myself but I guess some things 
are best left to the professional.

[Bill Coleman via CnC-List]

I think a lot of them just do have silencers. They expect low contamination
and I think that's all I've ever had like through the years. I think my
Yanmar just has a screen over the turbo. Niel's point, about 15 years ago,
I bought a Kubota four-cylinder diesel for the boat, and a Kubota 3
cylinder diesel mower. After a few years, I noticed changing the oil, that
the boat engine oil was always clean as a whistle, and the lawn mower oil
was black like my old trucks used to be.

[Bill Coleman via CnC-List]

I just removed a shitload of that crap. Some kind of white fabric
perforated nagahide with acoustic holes, and completely disintegrated black
foam. It makes me worried that it may have lead in it, I've heard sounddown
had lead or something for sound deadening. I replaced it with those foam
egg crate material. It's probably supposed to be fire retardant, and I'm
not sure. Maybe I'll try setting some on fire. Outside of the boat that is.

Stus-List Re: diesel engine air filter

[CHARLES SCHEAFFER via CnC-List]

Rob,
Happened to me too.  All of the sound deadening material fell apart.  The old 
material came out pretty easily though it's a dirty job. Covered the engine 
with plastic sheet and ripped off all the old foam.  Wet vac with bag collected 
all the gritty grime and I'm planning on a more thorough cleaning and paint the 
engine job, later.

I bought new sound deadening kits from Defender.  Covered the doors reusing the 
original screw fasteners to hold the spikes against the wood.  Haven't attacked 
the rest of the box yet.  That's the harder part.  Will have to wait till 
winter.

[Dennis C. via CnC-List]

To Josh's point:

https://youtu.be/sJ3L-E-ufYo

The particle test starts at about 9:00.

I have used K&N air filters in my vehicles for years.  Hmmm.  Rethinking
that.

Also, I worked for the company that made Fram products for decades.  I
don't use Fram products.

Stus-List diesel engine air filter

[Robert Abbott via CnC-List]

Josh,

You are absolutely correct about sound deadening material disintegrating 
all over the engine roomthat is the case on my boat...the stuff on 
my boat is now so old it should be removedthe black dust particles 
are quite apparent in the engine compartment.


Actually thinking about moving it and replacing it with either new 
material or a different material.
