Hello Everyone

[Charlie_Iliff]

I've been brain storming lately on what would be a good alternative engine for a Diesel PT would be, like for a repower. Would a liquid-cooled engine be able to fit in a previously Deutz powered PT? I'd like to find one with a bad engine and repower it with something. I personally would love to drop a 4 cylinder 65hp Cummins into a 1460 or 1850 sized machine. Or even a similar sized CAT/Perkins. Thats just me, though

I just think putting a Liquid Cooled engine in like a Sloper Mower machine would really bring it to life, and eliminate overheating issues. I think its kinda dumb they put an Air Cooled engine in a machine that works in a potentially dusty environment and after many over heating issues they do nothing about it. Just my :2cents:

Don't sell the Deutz short. In my 1845, the cooling problems have been solved by something as simple as insect screen, although I've also put a rotating drum filter on for more area.
In high-chaff operations in big-time haymaking, you'll see elaborate filters on all sorts of engines. Standard liquid-cooling radiators plug as easily as the Deutz oil cooler.
Two John Deere tractors, a Kubota-powered Jacobson mower and a Kubota tractor that I have had all have screens ahead of their radiators, which can and do plug up. The PT does it a little faster than all but the Jacobson, because the mower is out front and the tractor drives through the cloud it kicks up. Once you've mowed with the mower out where you can see it, however, you'll happily trade a little cooler cleaning for being able to see what you're doing.
On the 1845, you don't have to bleed the injectors after a filter change or running out of fuel. That's unlike the Deeres, Yanmars, Kubotas, Perkins, and Ford Lehmans I've had a little experience with. It cold starts, down to 14 degrees F, without heat or glow plugs.
The Deutz is in fact liquid cooled, using the oil rather than a second liquid. True air-cooled engines blow air over fins on the cylinders and head, which is light and simple, but difficult to control.
In short, I really like the Deutz, and wouldn't suggest going to the trouble to retrofit another engine, even one that's really good.

I would second my appreciating for the Deutz. Solid as a rock. Cooling is a bit of an issue but simple easy fixes seem to help. I will add that using Synthetic has helped reduce temps a few degrees and raising the air vent deflector had a major boost, keeping things a bit cooler but allowing me a longer time between cleanouts.

Also, 45 degree tilt. Not too many engines can say the same thing.

A third vote for Deutz. You see the engines all over for good reasons. They are rock solid. I don't mow a lot with it, but cleaning the oil cooler on the engine is quick.

I second Charlie's comments; Deutz's work better than any other engine that I have had in the same environments.

Bottom line, it just works, and it is a well designed, reliable engine.

All the best,

Peter

A fourth vote for the Deutz. I have reached a satisfactory situation on the cooling with two relatively simple mods--insect screen in the rear over the expanded metal where most air for the engine cooling air is drawn in and fabrication of a new air deflector that goes on top of the oil cooler to provide about 3" of additional height--with resulting increased air flow.

I really like not having to maintain a separate liquid cooling system--changing the oil regularly does it all.

Hey Bob. You got a pix of your mod to the top of the cooler. I am happy with mine (just raised it with some spacers) but love to see yours.

Can you explain how this helps?

Can you explain how this helps?

The stock air deflector outlet area is smaller than the inlet area. By building the deflector higher the outlet area size is increased to be equal to the inlet area.

Well.....I didn't know all that my :2cents: on the Deutz would attract so much attention :laughing:

I think its just I don't have much experience with the Deutz engine, or any Air Cooled Diesel in general. The machines I've been around the most have had either a 60hp 4 cylinder Cummins, a 64hp John Deere Turbo Diesel, or a 40hp Kubota Diesel, all great and bullet proof motors. All had thousands of hours on them and all ran like a champ. The Air Cooled Diesel "concept" is still new to me. Although like I said I'm quite happy with the Deutz our JCB front end loader uses at skill center. A lot of times I'm too quick to judge things, I'll admit

I would give one a chance. But if I didn't like it, into the crusher it would go! :laughing:

Well, maybe this summer if me and the uncle travel up to Traverse City, maybe we'll see a PT up there in an auction or something. Theres just about anything up there for cool equipment. My uncle's even said he's seen a Unimog go through one of them auctions! Do you know how rare Unimogs are?! They only sold them here for like 5 years and they cost like $200k! :confused2: I want to see one BAD! :drool:

Willie,

I think somebody else already posted this, but it bears repeating.

The Deutz is not air-cooled. It is oil-cooled.

Air-cooled engines rely on finned castings for direct cooling of the cylinder and head. An air-cooled engine can be splash-lubricated. Think Briggs & Stratton lawnmower.

Oil-cooled uses a pump and a fan and a heat exchanger/radiator. Although it doesn't use antifreeze and a water pump, it's more closely related to a water-cooled engine than to an air-cooled engine.

Make sense?
