Moving the air intake

[woodlandfarms]

I would like opinions on moving the air intake on my Deutz PT from the rear, where it sucks all the dirt the tractor can throw up, toward the front, by the oil filtering system.

It looks to me like you just swap but I wanted to make sure it would not effect fuel/air flow and that sort of stuff.

And do you think it would help? My poor filter is pretty mucked up just from driving on my dusty dirt road for a day.

Carl,

Are you talking about combustion air--which is taken in via the filter, or cooling air for the oil cooler which is pulled in via the fan mounted to the alternator shaft?

I have not personally had any problem with combustion air and the filter clogging. I do have to pay attention to the oil cooler because it tends to clog over time.

The one issue I would be concerned about would be heat--and want to ensure that the temperture of the air was not increased.

In either case it is unclear to me what can be "swapped".

Sorry... Lemme see if I can find a picture....

Hmm. I can't None that shows the intake manifold. Maybe you got one Ken an understand what I am asking? I want to move the intake air filter for the fuel injection to the front of the manifold port. On the Deutz, the manifold is a long tube with what appear to me to be identical ends, one covered, one with the air filter attached....

I would also love to move and increase the size of the engine oil cooler but that ain't gonna happen any time soon..

Will this suffice? It's of my 1845 but I dare say the layout of the intake manifold is similar and most likely it's a simple swap ends. Simple for you maybe, but my 1845 presents problems with stuff in the way of a forward mounted air filter.

Ok, now I understand.

The air filter housing is plastic. Swapping it to the opposite end of the intake manifold would put it pretty close to the exhaust--I would think that would be undesirable--because of the heat and because of the increased intake of exhaust fumes. On the 1845 I don't think there is enought space to swap--even if the filter were turned up. Perhaps the space is different in the 1850.

I also intend to re-rout the exhaust, continue the pipe back to the rear and then out. In hopes of reducing the noise this beast makes... It is too loud to not have headphones, but then it is too quiet to hear your brush hog bog down...

The last time I was at Tazewell, one of the PT employees was using a red machine (a 1430, I think) to do some parking lot work of some sort. I was struck by how quiet it was.

I lived and worked with air/oil cooled Deutz gen sets for three years, and the noise level was phenomenal. I expected the Deutz powered PTs to be likewise, but the one I saw and heard seemed no louder than my PT-425. Of course, it could have just been the angle and distance. It was about 100 feet from me, and its back end was facing my direction.

I use ear muffs that allow me to hear the mower but filter out louder sounds. They are not cheap but work well.

I use simple inexpensive shooting muffs that I have had for years. They work fine. I only use them for mowing.

A friend, who lives in Austria and is interested in things mechanical, told me that the primary goal in the engine redesign of the FL2011 engines was to meet European noise limits, not their emissions limits. Apparently, this is why the oil cooling runs around the base of the cylinder skirt.

On the other hand, the gensets use several different engine families. I can imagine that you were alot closer, and probably in a relatively enclosed space.

Deutz makes several variants on the muffler, one of which would point straight back; originally, I had hoped I could just flip the existing one 180 degrees, but I think that it would interfere with the intake housing.

Having thought about this for my machine, I think that one might need to relocate the hydraulic filter a little, but maybe not.

Carl, are you going to add the turbo at the same time?

All the best,

Peter
