Block Heater on a JD990?

[BWa]

I have the parts , tech , and owners manuals , picked up the block heater kit some time ago and figured it was time to put it in . Drained the fluid , got the kit out , heater , gasket, two bolts , and spacer.....looked at both tech and parts books , then the engine , book says need spcer , no place on the engine that the spacer will mount ...
Called the dealer and was told it fits ? /forums/images/graemlins/confused.gif
Before I take a frezee plug out and chance that it is threaded , and deep enough to take the block heater ...two questions , any one has done this , and if it not the right plug , how hard is replacing a frezee plug ?

I have thought about adding a block heater to my JD990. I will be interested in some pictures of your final installation.

Freeze plugs are not threaded. They are a concave metal cup that is tapped into place inside a machined or cast hole in the block. I usually apply a little sealer to the sealing edges and tap them into place. Make sure it is centered into the hole.

I would recommend making sure which is the correct plug for placement before knocking it out. Usually a tap with a screwdriver or chisel will dislodge the plug. Be careful not to chisel or strike the block !

Good Luck - Anxious to see your results.

Well now proven that I have the mechanical ablity of a duck , ... and work better with pictures , I have been all over the tech and parts manuals , the only out I can find is a pipe plug on the block on the opposite side from the kit picture install (parts Manual) . What really has me confused is that the kit picture shows a 3 cyclinder block , and the 990 has a 4, .????
None of the frezee plugs are fitted for the spacer , I many go look at this pipe plug but wonder if it has the room needed to mount the heater .... at least it is threaded ...

At least the tranmission heater I got at the same time is straight forward install. But will wait for the oil change to do it not really in to dealing with 5 gallons of oil twice....

Hi

Sorry to hear of your troubles. I may wander to the JD store today and buy/order a block heater so I can take a look at the installation and parts for my 990. Maybe I can figure something out and share the information.

Keep trying

I'd like to know where it fits too. After doing a "Where Used Search?" in the JD Parts list, the engine coolant heater P/N AR87167 is used on lots of JD equipment including CUTS (650-1070, 4200-4700, 2210) as well as lawn tractors, excavators skidloaders etc. However the associated pictures, don't show where it goes.

This is from a post about a block heater on a 2210. Does this help? 2210 Block Heater . Looks like it's on the right side of engine to the rear behind the injector pump.

I have looked at that area on my 990, it is the closes thing to having want may ? pass for machined fit of the spacer block and possibly plugged/ paint filled mounting hole ....but the amount of space between the injector pump and the block is so limited that even just the heater looks like it would not fit ....never mind the spacer or trying to install it short of taking the pump off... /forums/images/graemlins/shocked.gif

I'll take a look at my 790 tonight (similar engine as yours just missing one cylinder - 3TNE84 vs. 4TNE84). I also expect to see my JD dealer tomorrow and I'll ask if anyone knows about installation of block heater. BTW - JD allows only 1/2 hour to install - can't be that tough, can it?

BillG - Here's a picture of the place on the 790 engine where I think it goes. I'll see if I can get some more info from my JD dealer.

Reading this I am sure glad I opted to have the dealer put it in (for free) when I got the tractor. I will take a look at mine and see where it is.

If possible a picture would be great. Thanks,
