Hello,

I do not believe any specific information is available for block heaters.

What do you need to know?

What is the serial number of your machine?

I do not have it with me I need to know what freeze plug it goes into

The serial number can make a difference but, it should be close to this image.

I will log on tomorrow when I am beside the machine

Still looking but, I can only find this generic sheet.

It is for the 3054 engine.

I will be at work tomorrow, I can check back in tomorrow night or I can OPT-OUT for someone else to help you?

I just found the same kit is used in a C model and it has more specific info.

1. Drain the coolant from the engine.

2. Remove the lower 1.5 inch core plug from between the #1 and #2 cylinders on the right side of the block. Use a screwdriver and mallet until the plug begins to turn and then pull the plug out with pliers.

3. Clean the hole out with a rag to remove all debris.

4. Insert the(###) ###-####Heater Assembly (6) into the hole with the element positioned straight up.

5. Gently tap the Heater Assembly into the block until the flange is flush with the block. Use a tool such as a socket so that the pressure is placed on the flange of the heater.

6. Connect the(###) ###-####Cord Assembly to the heater.

7. Route the(###) ###-####Cord Assembly and secure using the 3S-2093 Straps.

8. Mount the(###) ###-####Bracket Assembly using the 8T-4189 Bolts and 8T-4224 Washers.

9. Connect the cord assembly to the(###) ###-####Covered Receptacle.

10. Mount the receptacle to the bracket.

This should be correct for your engine too.
