4440 block heater cord

isuvinny · Mar 25, 2020

The cord on my block heater is bad on my 4440 - so I am trying to take that off and replace. I need to get the down tube off (from the turbo I think) and move it a little so I can get to the heater cord behind it. I am having trouble getting the back bolt off on top. Not much room to get in there. Does anyone have suggestions? I don't really want to take the hood off if I don't have to. Thanks.

When I installed new heater in 4430 I installed it with the new cord pointing up rather than down and I didn't have to
take that tube out. Not positive the 4440 is exactly the same but that's what worked for me.

My cord is held in place with a lock ring. All I did was use channel locks to take ring off and plug comes out of block heater, plug new cord in and reinstall lock ring

I have an aftermarket AC compressor and it doesn?t leave much room there. I did get the pipe loose so I can wiggle it a bit - now I can?t get the ring to budge. I guess after 40+ years it doesn?t want to move. I will wrestle with it more tomorrow night. Thanks

You should have moved the AC compressor.

In The past 43 years I can't even guess how many block heaters and cords I have replaced on Waterloo tractors with and without turbo return pipes in the way, There is no need to remove pipe as it can be done with pipe in place. Return pipe cannot be easily remove with manifolds and turbo in place / in the way, and you do not want to take all that apart when not necessary. Go to Menards and buy yourself a plumbers tool called a "Basin Wrench" used for installing sink faucets. This pipe wrench type tool has a pivoting head that will put handle at 90 degrees to jaw and you can not only reach behind pipe to remove cord nut but, also take nut off the original design heater to replace it. Works great! I have two of them one for the road box and one in the shop. Never know you may need to replace the sink faucets someday too!! DW

I guess you want to replace the whole internal block heater not just the cord? Both my 44's have ample room for cord replacement, but I've never replaced internal coil on them. Cab tractor looks doable though without removing the tube, work from right side, I have a Delco compressor and it's note in the way. The other is a 4 post and I could use a pipe wrench there's so much room.

The basin wrench was absolutely the right tool! Thanks for the suggestion!!
