I sure did hear it squealing. When I sent an employee up there he decided to change the belts and when he changed the belts he added extra tension on them. If you look at the angle in which the shaft went almost exactly lines up with the angle that the belts are on.
Built a mount for the new piston style vibrator. Now I have to find another use for the old ball vibrator.

There's a lot of jokes to be made here. I don't know where to start.
How on earth are you people destroying bearing blocks so dramatically?
Like, did nobody notice the loud squealing sound for a month?
Its complicated..... very, very complicated. Ill just say were union, government, post office. Add to that a dash of manager that is trying to spite the craft by contracting out their HVAC work, which in turn makes the craft spiteful about the job...... I'm sure 10 people heard it and said "well **** Honeywell and that one (aforementioned) manager". I also heard it quite some time ago and decided that it would notify the pertinent people, eventually, itself; and it did last Thursday. The night shift got called up there, 3 guys looked at it and still didn't see what's pictured. They turned it over to us (day shift maint) with "its running hot, maybe take a look?".
This is a 3-inch diameter whole for the lower Center hitch on a wheel loader. Machine weighs about 30000 pounds. The pivot only turns 40 degrees from center in each direction. This is where the machine bends in the middle to steer. There is a grease point that is to be greased daily or every 10 hours by the operator. The operator rides on the machine just above this pin's location and can easily feel even a quarter inch play.
The owner said my operator greases that machine every day. We don't even bother arguing with people anymore.
Reminds me of the story when a customer called and wanted the boom on their tele-boom crawler replaced under warranty because it bent. Once we told them we were going to sent a representative out to inspect the boom and pull the load data off the crane. After they learned we could pull data from the load management system, they called back asking for just a quote for a new boom instead..
I always try to use sealed bearings for things like pillow blocks and other uses where people can under/overgrease things (KISS principle). I can't tell you the number of times I have opened a motor to find the single-shield bearing was installed backwards and the stator was full of grease. Or, there was no grease in there at all.

This was an open-sea vessel, not a lake-duty fishing boat. It's my recollection that each of the two engines did have an automotive style closed-loop cooling system, with an expansion tank and all the stuff you'd expect under a car hood except for the radiator. Instead, the engine coolant, after passing the thermostat, went through a heat exchanger which functioned a bit like an air-water intercooler, but with water in both halves. An auxiliary pump driven by the accessory belt drew raw seawater in from the underside, passed it through the heat-exchanger to draw heat from the engine's primary coolant, and then dumped the warm raw-water output of the exchanger into the exhaust manifold, or a device very near it. A thick rubber hose exiting this then led the seawater / exhaust mix aft past the gearboxes. I do not recall the routing that the hose took on its way to the outlet at the stern, nor whether the exhaust ports themselves were above or below the waterline.
I'm trying to find a picture of a similar engine bay, but Google isn't being my friend. The net effect of being down there was not entirely unlike this, but wider with enough space between and aside the engines for a 10 year old kid to fit into:
Kind of halfway in between the two, and accessed from the top, by pulling up a couple of large deck panels in the cabin just aft of the galley.
I can almost guarantee it's just to help suppress the fumes and noise. Since it's more of a "luxury" boat. Really any boat that isn't just for going WOT all the time it's best to have all the fumes and gasses exit under the water. You never really want to hang out on a swim platform or be at the back of the boat with it idling either.

Probably with how the boys have a nice lather chair in the shop. Just out of frame is the newspaper and coffee machine.

Literally every motor i've ever sent out to have rewound had grease in the windings. I tell them to remove the zerk and plug it. Motors seem to last longer when some kid isn't allowed to pound 15 shots of grease in without ever removing the plug at the bottom.
Engineering: Yes they actually specified that very c-clamp in their instructions to brace up this beam, along with the stiffener plate in the back.
