New Video - Garlic Shop - Caterpillar D6C Repair.

In this video, Garlic Mom and I try to finish the water pump repairs to our D6C.

The poor D6C water pump was leaking, so we took it off to be rebuilt.  This involved removing the hardnose covers, removing the radiator and pulling the water pump off the front of the engine.  Unfortunately, that happened about a year and a half ago and we didn't video any of it.  Maybe a good thing because we didn't really know what we were doing and I made some mistakes along the way.

I didn't realize the radiator had bottom bolts holding it in, so I didn't remove them.  I used a lifting eye on the radiator cap stud to lift the radiator and broke the stud out of the top of the radiator because I didn't know to remove the bottom hold down bolts.  Luckily, the radiator is O. K. and I think I can weld the stud back in to hold the cap on.

We got the water pump back from the shop and already have it installed at the point that the video picks up.  The video shows us reinstalling the radiator, upper and lower water connections, filling it with water and firing it up.

So far, no leaks.  We have another problem though, which developed while it was sitting.  It now doesn't want to pump fuel through the transfer pump and into the fuel filters.  There is good flow when I remove the line from the tank to the sediment bowl.  I think perhaps the screen in the sediment bowl is plugged up, a passage from there to the transfer pump is plugged or perhaps the transfer pump is worn out.

My buddy Daron used to run a D6C with a dirty fuel tank.  He said he could work for a shift or two and then the brass washer filter stack in the sediment bowl would get plugged up and it would starve out for fuel.  He'd have to remove the sediment bowl and washer stack and use a toothbrush to clean all the coffee grounds out of the washer stack.  After about an hour cleaning, it would flow again and he could get another shift or two of work.

We'll probably have another video later where we diagnose and try to repair that problem.  I hope it is just the sediment bowl filter stack or a passage which is plugged from sitting.  Replacing the transfer pump is more involved and expensive.
