Block Heater on a JD990?

[johnbilt]

Pulled the (heavy, oomph!) rear tire first, and supported with a jack stand.

Here is a phot of the plug where the heater has to go. I pulled the parking brake rod out of the way for better access here.

Final install of Trans heater. I used the clamp to hold the wire and a cable tie near the ac plug to keep it from flying around.

John - Thanks mucho for the great photos and instructional text. I take it the heater fits inside the transmission screen?When you get a moment can you post the part number of the complete kit for the Transmission Oil Heater. I see the individual components on JD Parts, but not the kit. BTW it appears the same unit is used for many JD CUTs including the 670/770 (not listed for the 790, but I'd bet it fits fine). Thanks.

Sorry if I'm missing something.. I just scanned the thread briefly as I don't have a 990...

But...

Why not just drop by the JD dealer and ask them where it goes? /forums/images/graemlins/grin.gif

Hi

The trans heater does fit into the suction strainer cover. The JD mechanic showed me the right place. JD did not list a kit number.

I was able to swap the cover plug and heater and only lose about 4 -6 oz of trans fluid. Get everything set and go for it ! Put a bucket underneath for the excess..

The trans parts are:
AR94493 Heater Element $43.50
AR95434 AC plug and Wire $12.75
R34557 Clamp Z34587 $1.50

Good luck All
John

Thanks for the great pics. I don't have the trans heater but it seems easy enough to install. How easy is it to plug it in with the tire on?

I was thinking the same thing ,hate the idea of wreslin' the tire off and on , with the wheel weights and all ........... Wondering if I can jack up that side and sneak it in without a gush of oil to worry about ...

Hi Zuiko

There should be plenty of room to do it with the tire on. I debated about that myself, but the JD mechanic recommended it, and it wasn't that big a deal for me. I don't have any wheel weights, although it is still a heavy assembly.

You may lose a little more fluid since you will have to put the plug in from a sideways angle, but it shouldn't be significant. I would pull the pin that holds the brake rod, and lower it out of the way.

As far as removing the wheel, just jack up the rear axle until the wheel slides off the hub, and then just roll it back and rest it against the ballast box, or other handy implement. Do the reverse to mount it back up. There is no need to lift the wheel and tire, just some gentle wrestling...

Please remember to put a jack stand under the axle at all times for safety !!! I had a friend crushed and killed when a jack slipped and he was working alone many years ago...Ouch


Good Luck and Have Fun,
John

Bill - I don't know when you last changed the tranny/hydraulic fluid and cleaned the screen/filter, but when I did mine a few months ago, the screen really needed to be cleaned.

BTW this tranny plug is MUCH easier to remove than the block plug heater, however you do need something large enough to catch all the oil. Just a thought...
