Kubota - BX 1860 and G1900
I tried unsuccessfully to install a block heater in my BX1860. Ordered this part (70000-73595)

Block Heater.jpg

Removed muffler (muffler crosses front of engine, very close to engine block), took out the freeze plug at front of engine and installed the heater. Easy-peasy, I thought, no problems! Then I went to put the muffler back on and it won't fit because the heater extends too far out of the freeze plug. Not even close. Ugh!

I see all kinds of information about seemingly every BX EXCEPT the 1860. Anybody have one with a block heater? I'd love to know the location where it should be installed and the part number (if different).

I have a WSM but don't see anything related to block heaters.

The BX fires right up, even in single-digit temperatures (cold for around here) but I know cold starts are particularly hard on these diesel engines.

Thanks for any help.

Can you modify the muffler to fit? Maybe either a spacer where it mounts to the exhaust manifold, or a modification to the piping? Or whack a dent in the muffler to fit around the heater? I am not familiar with the muffler/mounting on that tractor to get more specific. But mufflers are pretty low-tech, and it's probably easier to modify that without ill consequences. Either that, or run without muffler and get some earplugs! ;)

Have you looked for a port on the side of the block? My BX has a plug on the center of the block on the right side that looks like a large allen wrench plug. It is for the installation of block heaters.

Thanks s219 and daves1708. There is only 3/8" or so between the muffler and the front freeze plug. I can't see any way to move or re-route the muffler. I'll reserve denting the muffler with a hammer as a last resort. :)

I see threaded ports on other BXs, but I don't think I have one. (D722 engine). I see other freeze plugs but don't know if there is room behind them for a heater element. The only recommended location for a heater I can find is the front top freeze plug (where my muffler obstructs its installation).

There is a threaded port on the lower thermostat housing. It seems like it would be too high to effectively heat the engine block. Anybody know if that is accurate? Anybody know the intended purpose of the threaded port on the thermostat housing?

Thanks!

I see you reference a Messick's image. Did you reach out to them for guidance on selecting the block heater?

I was also uncertain re: fitment and extensive searching/reading only made things less clear. The folks at Messick's were very familiar with the the various heaters and fitments and sold me the right part.

Probably not much help to you (part no. 70000-00771), but my install is documented HERE.

I was told the only option on my BX1850 was the lower radiator hose. Even it was a tight fit.

Thanks, guys, for your help. HeLa, I called Messicks today and they were helpful. They said that the 70000-00298 part (lower hose heater) was the only heater recommended for the BX1860. Your install thread was very good and I wonder if the same thing would work on my machine. I see a freeze plug at about the same location - easily accessible, but I don't know what's behind it. It looks like your heater is designed so that it only extends a short distance into the engine block. I'd sure prefer to use that type of heater.

Ford850, I think you're right that I got the wrong heater. It fits just fine, unless you are one of those crazy types that wants a muffler! :) The link you provided was helpful, too. From what I can gather the 77700-00298 part number is no longer valid. When I talked with the Messicks guy today he said the only option is a hose heater.

oldnslo and 100 td, the part you reference (100 td) is the one the only recommended one for the BX1860.

How does yours work, oldnslo? Did you install it yourself?

Maybe I am overthinking this, but I really would prefer to have a block heater. I am tempted to attempt an install like HeLa; I guess the worst that could happen is I have to re-install a freeze plug if I see there's no room behind it. Well, there's always a chance I put a hole in whatever is behind the plug, but I'd be careful.:eek:

Thanks again for your helpful replies. I appreciate your help.

i wish i had taken more photos in the process :-/

the element on my heater is in fact very short. additionally, the space behind the freeze plug is limited in depth and width (the element MUST be oriented vertically to clear).
