Difference between a Keystoker KA6 and KFA

Thank you for your help my drive shaft look like it was made out of plastic it has two hex inserts on either end that you can remove and swap I ended swap ends out on mine because when the gear box locked up it wiped out the drive on the motor end I am going to have to buy a new one just to make sure it will work when I load it up it also sounds like I really should buy a new gear box as well. when I install the new one is there a procedure I need to follow to line everything up also I was wondering about the motor it looks like a furnace motor it is short I will take a picture of it tonight and post it



Thank you
Bill

It's the same as an oil burner motor. The only thing that could be adjusted for alignment would be the gear box I suppose, I have to look at mine when I get home.

I just looked at my unit to confirm and the motor is labeled “oil burner motor.” The gearbox does not appear to be fastened through elongated holes so there is none to minimal adjustment of the gearboxes alignment to the motor. If there is a problem there it would have to be from damage to the units mounting surfaces of either the motor, gearbox, or both. It could have been a manufacturing defect but I would have to believe that would have been addressed years ago, soon after it would have been put in service.

Thank you gaw for all your help I got the gaskets for the back of the hot water coil and the blank plate I am going to order a new gear box and drive shaft next week Rob I also want to thank you for your help as well I am sure that I am going need advice when I fire it up.

Thanks again
Bill

Good evening everyone I started working on my boiler and got some surprises I pulled the DHW coil out to put new gaskets in and found rope in side the boiler and that the top of the fire box had about a quarter inch of muck on top looks like I am going to do a full rebuild on it I called Keystoker and ordered the weld adapters for the DWH coil and the blank on the other that way if it starts leaking again it wont leak on the back of the boiler here is some pictures of what I found and my progress

memco, Was that Keystoker used for steam before??? Muck is unusual for a hot water boiler, I think???

Hi McGiever it good to here from you ,I really do not know the history of this boiler it is almost like someone ran pond water through it I also found some leaves in it I have no ideal how they would have got in there. I am thinking about pulling it out of the garage and taking the return line off and the plug across from it and running the garden hose with a nozzle and see if I can flush it out before I put it back together it can't hurt anything

Sounds good. Might raise one end higher by blocking it up opposite from low drain port before hosing it out.

Sounds like a plan thank you McGiever

As far as I can make out ,it looks like your stay bolts in the unit are fat and healthy yet. That has got to make you feel good. Mike

With that much muck in the pressure vessel, you need to pull all plugs and bushings out of both return ports to flush it all out. Hot water and a pressure washer will make it go faster. With those DHW coil plates out you can get right inside the steam chest for a good through clean out.
Good Luck!

That boiler looks like it was run with a big air bubble in the top...and pond water.

A good rinse with a hose should take care of it.

If it was left outdoors with one or both coils removed it could pick up a bunch of leaves that over time could decay into muck. Then there's always the possibility that pond water did, in fact run through it - Post by Matthaus - Installation Plans for the Gentleman Janitor .

Hi everyone thanks for your support and advice I really appreciate it Mike I am not sure what a stay bolt is that those rods that run from the top of the fire box to the out side of the boiler? should I be looking at them closer? I did some more work on the boiler I took the stoker off the boiler and took the grates out looks like I am going to have to drill some of the holes out I can't poke any through some of then the air space was packed full of ash here are some pictures of my progress (I though that I was going to just pull the stoker off only two bolts right wrong the inside bolt was spinning and I could not get in there to hole I finely got it loose enough to get a screw driver in there to hold it ) When I put the greats back together should I put furnace cement all the way down on the far left and right side and how far down from the top of the greats should I go in the middle with the cement ?

Thanks again for your help
Bill

That pile of ash is what came out of the burner I don't know how it ran
