In this vid I service the seacock gate valves, install the battery shelf and disassemble the gearbox ready for servicing. I also remove the Detroit Diesel heat exchanger core for cleaning.

Stu I really appreciate your subtle sense of humour which often provides at least a smile, the remarks about 'morse code' and 'dissolving body moments' were particularly amusing.

A couple notes from an old guy who once rebuilt gate valves in Uncle Sam's Canoe Club (The U S Navy!). First, the most important part of those valves is the ringlike face of the gate proper, where if meets the flats on the inside of the valve body. Best to hone the faces, gently, on a flat surface covered with fine emery cloth. I think that would be particularly important on a valve that had been soaked in an acidic or caustic solution. Both sides, and check for flatness. Remove as little metal as possible. Second, and I'm sure others have pointed this out, flat packing is actually quite common in large valves. Cut the ends of the packing to scarf, meeting at an angle instead of a butt. You'll have no problem. Oh, and that thing is called a "rising gate" valve. The other variety is a "rising stem" valve, for those who are interested in that kind of detail. Good luck!

Once again, great video! Good old fashioned hands on repairs. No throwing away and buying new. I think that's why I enjoy this so much. So many people would have just bought new gate valves, rather than servicing the old ones. I am so excited about that Detroit diesel!!! Be careful with that caustic solution! Stay well my friend!

Just a tip with the gate valves, don't keep them cranked all the way down or all the way open. Get the feel of when the spindle stops and then back up until it catches the gate (from no weight to just when the gate moves) that is closed or open. Turning them all the way down right or open will eventually break the spindle. If the gate is in position it is working, doesn't need to be tight. Awesome work, love the videos

After just looking at a few comments and not seeing the answer, I'm going to throw it out there. Teflon tape, the wider stuff would be best for a valve that size, twist it up in a nice tight cord, then just wrap and pack it around the shaft! All packing is, is Teflon. If you want the warm and fuzziess then use some pipe dope on the top, then tighten up and tweak until it seals! Love the channel, you've taught me so many tricks, thanks so much. Much love from a Northern Michigan Plumber lol!

The white vinegar works great. After a salt away flush, I set up a loop and flushed my sea water coolant system and heat exchanger with white vinegar at 50/50 solution and the clear white vinegar soon became a cloudy blue fluid as the calcium dissolved. left it running for 5 hours, then thoroughly rinsed through with a hose left connected.

Never the wrong tool. It's always the right tools. May be the wrong job, but always the right tool

Powdered graphite on packing cord helps and extends the life of the packing material in fact they make packing for these valves and it's cheep. Works better looks better and is more reliable impregnated with graphite. However as a Master Plumber Pipefitter I say good job well done. Jack of all trades, lol. I enjoy your show and you inspire me to fix up my three boats. Resealing an 1989 OMC Cobra lower case installing prop shaft bearing, revised detent to fix hard shift and no reverse. Working on 1975 Mercury 650e Thunderbolt 3cyl a 1968 Johnson Super Seahorse 33hp and a 1971 Mercury model 40 4 hp 1cyl. Coming into ownership of a Mercury Thunderbolt 50. So I thank you for the guidance and inspiration to understand the gear boxes on these machines. I'm an experienced auto and small engine mechanic even done a transmission or two in my day but something about gear cases is intimidating like rear ends. Surprising how simple they are after the initial apprehension. I don't however remember seeing you tackle outdrives much. A great resource for those is Wayne Coll and

Good choice to have someone assemble the gear box. Always better to have someone do it that does it

cut the ends of the seal at 45 degree angle so they overlap and stagger the joins around the shaft so they don't sit on top of each other

The caustic soda segment is FUNNY!!! From Archimedes to Breaking Bad references is classic! Well played, Dangar Dude!

every time you take a bolt or something off I feel a moment of stress "how will we remember where this goes when its time to put it together!?". Its a HUGE relief when it all goes back together. what an emotional roller coaster ride!

I use graphite packing rope for large gate valves on steam boilers works very well

@mikeskelly2356 4 жыл бұрын

You can buy fancy but expensive teflon 'rope' for the packing, or you can just twist up your own from teflon tape. Worked great for me and no more drips...
