800 case block heater

TVB · Dec 23, 2008

Where can I buy a block heater for an 800 Case? Manual says 3/8" pipe thread and 5 1/2" element. So far all I can find is 3/4" thread. I'll try the CaseIH dealer next time I'm in town but thought I'd put the question out here as well.

Putting a frost plug heater in mine shortly. on the left hand side of the block there is a frost plug. I beleave it takes a 1 3/8" foros plug heater. Can find out have it sitting on my truck seat. Don't think there room for a hose heater. Might get a tank heat fit. Useing the tap where the OEM heater was

As of about 2 months ago, Case still had the original threaded heater and cord for the 400, which I suspect will fit the 800 motor. The price, believe it or not, was less than all of the other block heaters I priced. Here are the part numbers I came up with:
Original # - A40637 & LR1843
New # - A44815 & A44814

I was quoted c $35.10 and $14.99

As it happened, I used an old externally mounted heater hose type heater that came on an even older MM I foolishly let jump on my trailer one day last summer. On my 400, I ran a hose from where the block heater had been up to that long tapered water casting on top of the heads. Works fine.....and cost me $3.05 for one pipe fitting I didn"t already have.

Started right up at -15. Tractor was a lot warmer than the operator!!

DAve,

You might want to check the frost plug size carefully before you get to far. I had a leaking one on my 400, and it is not a standard size, so a plug heater may not fit very well.....

if you put on a tank heater throw the instruction sheet from Kats in the garbage and plumb it to push the hot water into the block, less dense warm water naturally rises, take cold water out of the water manifold, Kats tells you to push the warm water into the top of the engine, on a Case this warms one cyl. head and a heater doesn't do much, we have proven this many times on many kinds of engines, they work way better the way I plumb them.

that I will thanks for the heads up. Put a new frost plug in a few weeks ago. Went buy that size

DAve,

Sounds like you"re way ahead of me.
They must have changed the frost plug size along the way...mine are 1 13/16".....

Thanks Larry !!!
This post has really helped me. I have a Cat 416C IT back hoe and have been trying to replace the leaking block heater for a year now. Cat (Toromont in our area) have been pulling their hair out trying to figure it out for replacement and can not supply anything that will work. The 416C in this model year uses the Perkins brand name engine under Cat . Later years are Cat named Perkins engines due to Cat purchase of Perkins. I did a search on my LR 1843 number on my old heater and found your post. I now have a new block heater coming to me in Kitchener from Peterbourgh for the morning. Thanks for all the part numbers. Awesome help.
