643 D1402 water pump issue

[[email protected]]

So on my water pump directly underneath the pulley shaft there is a little metal outlet it is about 1.5" long and 1/4" in diameter. There isn't any hose or line connected to it but it drips water and when I turn it over it drips water faster. I have yet to start it but I can only imagine that its going to spray when its running. My question is, what is the outlet for? does it need to go somewhere or does it just keep plugged? Thanks! Jason

Typically water pumps have a weep hole under the pulley to let you know when the seal has started to fail. I've never seen one with a pipe connected. I'd start shopping for a water pump very soon if it was me.

Like OM says, sounds like a weephole with a tube pressed in. I had a D1402 in my new holland but cant remember what it had.

Oh okay! Well good news is they aren't very expensive haha. But that's good to know cause it wasn't running so I pulled the head and found it was cracked in all 3 cylinders. So it overheated at one point and that's probably why. I have yet to get it to fire it's got a new head now but I just drain the battery trying to start it. It's real close to doing and I'm gettin good black smoke it just won't fire but my battery starts getting real tired and I think my starter goin tits up cause she starts smoking and get really hot

Hard to say on your starting issue. My 1402 was the same way. They need cranking speed and glow plugs. Kubotas generally need glowplugs even on warm days. My 1402 sounded like a gas engine and started hard towards the end, looking back it may have needed the valves adjusted haha. It didnt have the diesel knock at all when it Idled or even started cold.

Well it's pretty old. I think it's an '85 and the meter reads 6500 hrs and I know it hasn't ran for awhile I got it a year ago so it's just slow goin. I adjusted the valves when I out the new head on last week I couldn't find the clearances so I guessed at .007" and .010". I just hope that once it does start running that starts easier but who knows. It does have a pretty distinct knock when it's turning over not a rod knock though

Did you ensure the glow plugs were in good shape and working? some of the older engines, especially if there were a lot of hours, give it a good glow first.
My 743 that ran a V1702 needed about 15 seconds or more glowing to get it to start without spluttering when it started.

Oh yea it's got new plugs. And I've been givin it a shot if starting fluid to help it out and I learned that you only do that AFTER you heat the plugs cause if not the starting fluid goes boom inside the cylinder.... Whoops.

Be vary careful with ether, it is known to blow apart pistons. You may want to do a compression test to see if something else is wrong.
It should start up easily with glow plugs alone.
