Block Heater for an Oil-cooled Deutz

Hello!

We have a Terex mini wheel loader here at work and I'm trying to get a heater for it. Instead of air-cooled or water-cooled, the machine's hydraulic oil circulates through the engine's water jacket. Great idea because there's only one radiator and the engine warms the hydraulic oil. Kind of a strange bird, though.

Trouble is, there's no easy way to get heat for winter starting. It has a manifold heater that works great, but it's gets cold up here and it needs more help.

Terex doesn't have anything for it, and I put a call in to a Deutz dealer and he's going to check around.

There are no standard frost plugs in the block where I could stick a normal Katz-type heating element and I wouldn't want to scorch the oil, anyway.

An oil pan heater would help... it that my only option? I appreciate any ideas. Thanks!
 
Stay awy from those pan heaters. Has been covered on here with an "in line" water heater. But they are for water hose size systems. Also they would only be able to take the pressure on the return side of the system. Just doing some thinking here for you. I remember seeing an artical many years ago about a delivery truck fleet for a news paper or dairy delivery milk trucks or such. They parked the whole fleet every nite and every trucks oil system got plugged into a cleaning, filter, and heater system. Never changed oil individually cause the whole system was monitored for acid and breakdown. Pretty neat. Would guess it was in the late 40s early 50s.
 
They make oil pan heaters that glue on, a friend of mine put one on a Cummins in a Dodge truck, I'm not sure where he got it. If you Google oil pan heaters you will see some, Kat's and Zerostart are 2 popular brands. They make magnetic heater up to 300 watt, if the oil pan is flat and steel you could put a couple on, but they are $50 each on Amazon. I doubt if a 300 watt heater on a big oil pan is ever going to burn the oil. I have a smaller one (200 watt) and it will make the pan slightly warm to the touch in an hour. I use it along with the factory block heater on our JD 4600, and in an hour or 2 it starts just like summer. I do this because I run 15-40 oil year around, we don't use it much in the winter, but I have started it as cold as -20F. it is in a unheated garage, but being out of the wind makes a big difference when preheating with small electric heaters.
 
Yeah, I'm wondering about an in-line hose heater. The oil supply and return hoses are right there in plain view. 3/4 inch hose, I think. Maybe, maybe.
 
Deutz guy got back to me. They have a 120V 150W heating element that threads in a bung in the oil pan. $86.25. Maybe, maybe.
 
Thanks, Russ. Deutz has an element heater that fits in a bung in the oil pan for $86. Might do that. Maybe enough heat will migrate upward to the cylinders?
 
I have a Willmar 4500 loader that has an oil cooled Duetz motor. It has the heater in the oil pan. It works well. The heat transfers up through the block.
 
My experirnce is that oil pan heaters were marginally helpful, dipstick heaters were absolutely useless. You have a rare bird there. Don't think an extrernal tank heater would work either.
 
150 watts isn't much, but if it's in the oil it's more effective. One thing about magnetic heaters is you can use them on multiple engines, but you should take if off when your running it. There are some engines that have aluminum oil pans, they won't work on them!
 
I have a couple of machines that have the deutz air cooled turbo diesel. They have the oil pan heater. The magnetic heater was worthless. The oil pan heater helps but I plug it in at night and leave it all night.

Good to see somebody wanting to prewarm the engine properly instead of using ether or a torch.

This company has immersion heaters that are rated for use in oil. While it may require welding a bung on the side of the oil pan. The heater can supply a wicked amount of heat to the oil which will rise and warm the top end of the engine . 450W or 1000W will warm the engine pronto.

A heater pad under the battery and a battery maintainer will do wonders for sending power to the starter .

I put a 600 watt Katz in the 3/4 oil drain hole on a G JD. Plugged it in and timed the temperature rise on the oil. In an hour it was up to 160 degrees. Kinda smelled like warm oil around it but the crankcase was getting warm.
 
I salvaged a tank heater for the junkyard once, and put it on our JD M, it was 1500 watt. I plugged it in once with the tractor outside, it melted all the snow off the hood, that little 2-banger started like summer!
 
I have one on a Subaru Outback that is wonderful. It uses a silicon rubber heater that will conform to surfaces really well and the glue has been holding perfectly for 5 years. Jim
 
Dont know how cold you want to start but a 150 watt is next to useless. If you are in a truly cold environment and that flea heater is all that is available then I would drain the hydraulic fluid and replace with full synthetic hydraulic fluid --- replace the engine oil with full synthetic engine oil as well . One good thing that I can say for Belarus is on there tractors you can take the hydraulic pump out of gear for cold starts--- this is a hellofa good idea --- wish other manufactures did this .
 
Yep I agree on the pump disengage. Good idea they had. Engine oil is full syn. Don't know what it has for hyd.
