JDcrawlers Messageboard

Thanks. It was 10 degrees this morning in Pennsylvania. I thought about using your method
Good to hear it works. I'll give it a try. Planning to butcher a steer in February and need to make sure my crawler starts!

I think I understand. You put a silicone pad heater on the oil pan to warm the oil and then you installed something like a Kat's heater to warm the coolant which then warms the block. I assume you drilled out the taped hole where the drain valve is to increase the inlet to the Kats. I guess I could ...

I run 30 weight oil in my engine. I would like more info on your block heating kit. I did not understand what the adapter is or what is the "bung on the existing plate" mentioned in your post. I can weld so that would not be an issue. I appreciate any help you can supply. Thanks.

The Kat''s heater sounds like a good solution. If I understand correctly, it really works on natural convection. Cold coolant enters the Kat thru the bottom port and the heated coolant rises out the top port causing the circulation of the coolant. Correct?
Thanks for sharing this with me.

Has anyone used a magnetic block heater on a JD440 diesel engine? If so, how did it work and how many watts was it? Are there any potential problems or issues with a magnetic block heater?
Thanks

Jim,
Can you give me information on a block heater or coolant heating system because that would surely solve my issue. I keep my crawler in an unheated pole building. It is sealed up against the weather and I have power available.
Thanks!

Hello,
I never have an issue starting the diesel engine during the warmer months but when it drops below 30 degrees it can be a challenge to start. Thanks for the idea of using to batteries in parallel. I didn't think of that solution.

Thanks

Thank you for the reply. After my post I realized I should have included more information. I have a 1959 JD440 diesel with a 12 volt system. I have the GM diesel engine. The original battery box was rusted away when I got this loader in 1982. I currently use a battery with 1100 cca. I have the origi...

I need a new battery for my 1959 JD440 crawler. What is the recommended minimum required cold cranking amps?

Thank you for all of the suggestions. This site has alot of good people trying to help solve problems.

The previous owner of my 440 diesel crawler removed the oil filtration system from the dozer and plugged the ports on the engine. Can some recommend an oil filter system that I could install on my dozer? Thanks.

Thanks. The Wix 3513 fuel filter worked like a charm.

I cannot find a replacement fuel filter for my 440 diesel. Can someone recommend one or where I can get one?
