Temp Gauge

[Anonymous Poster]

Hey Guys - How is the spring going?

Ok I got a question for the 1845 guys - I checked out the overheating post - but didn't see it - what does the temp gauge measure - engine oil temp or hydraulic fluid temp?
because I pinned the gauge yesterday but didn't notice it at first - I guess I was not expecting it - I used my slicer and sliced up a few acres for overseeding in two directions and then I went back with the vacuum I fitted the unit with and was vacuuming up the thatch - thats when it happened - I shut the unit down as soon as I noticed it - opened the hood and noticed some grass / debris clogging the cooler - cleared that away and it seemed to solve the problem - this is not typical work for me - so I don't think I need the screen you guys came up with - but that cooler is the hydraulic system - right? - nothing to do with the engine - except indirectly right?

Your guys thoughts would be great -ED

PS - I hope to have some photos soon - I have some neat little things built for the 1845 I'll show you - also finished up the vac etc - for the 425 and then delivered it to my brother in law - he is going to snap some photos when he gets a chance

Hey, Ed. Good to hear from you again. The vac attachment for the 400 series sounds cool.

Ed:
The temp gauge measures the engine oil temperature. The alarm is also wired to make its inaudible beeps with either high engine oil temp or low oil pressure.
The cooler in the top of the engine cover is for the hydraulic system only. The oil cooler, which is the only engine cooler, is on the left side of the engine under a removable cover. If you had chaff in the hydraulic cooler, you definitely also have it in the engine cooler. Some will be visible on the fins, but the oil cooler has very tight and busy air passages, so you probably will want to remove the side and top covers and shine a light down into the cooler. You will want to blow it out and even rinse it, but be careful not to use anything that leaves a residue to catch dust.
I found, and I think Sedgewood will concur, that once it started overheating, the culprit was hidden chaff in the cooler, which was not dislodged until high pressure air was blown straight through.

wait till you see it - with the deck out front and this in the back it is real long - my brother in law has 3-4 acres with wide open space so no problem turning around - it is semi mounted so it does not jackknife and holds I think like 40cuft - I went for a unit that is easy on/off with pins - the tough part is holding the hose up while allowing for articulation - we used quick removable holders with springs - it is also light
I think overall this unit is a better solution vs. my orginal idea of a mounted hopper with hydraulic dump - it is cheaper, lighter and less complicated -

I used the same basic unit for the 1845 except one size smaller because I wanted to modify it and make it fully mounted - that works better for me since I have tighter spots and hills which makes a trailer unit tough to turn around - it still comes off with two pins -

Sounds cool...very interested in seeing those pics...might help me with my leaf cleanup at home!

hey Charlie thanks for the reply - surprised to hear that since cleaning the regular cooler seemed to work - is it what looks like a cooler on the right side (when standing in front of the engine) towards the top front ?? that has a top cover which I didn't take off but it looks clean - I guess I have to take it apart - you have any photos of what you guys found?

Ed:
The fan pulls air from the back and blows it into a plenum on the left side of the engine. (Facing forward) The air then goes up through the cooler and is exhausted out the left side. The left-side plate on the plenum, below the cooler, is held on by two bolts. The top plate is really a diverter to the left, but covers the top of the cooler so you can see it, but not get at it without removal of the diverter. The bolts holding that on mine are torx, but a 12 sided metric socket works. To get it really clean, you need to remove both, and then blow it out downward, against the usual flow. Then, hold a white paper under it and shine a flashlight down through it. You'll be amazed at what's still there.

Since getting the air compressor out is more effort than the garden hose I tried water instead and to my surprise it worked better than air; flushed it clean in a jiffy. As a precaution I stuffed an old towel in around the alternator and electrical connectors first to keep the deluge off those sensitive bits.
