Oil & Fuel hydro oil on 2310

[Bever22]

Do you really need to change the hydro oil at the 50 hr sevice or just the filter? I have been told either way but I am wondering what some of you are doing. Thanks.

Its your investment. As far as I know everyone here is doing the complete service.

Replace the oil, replace the filter, and clean the screen behind the left rear tire. You will need to remove the BH to access the filler and the level indicator.

Don't forget both sides of the front axle have to be changed also. It uses the same fluid.

If your interested in synthetic oil, Amsoil makes a hydraulic trans fluid, (ATH), that offers much better lubrication at low temperatures.

A 5 Gal. pail will do it all with some left over. It does not take all that long.

My first winter arrived for my 2004 GC2300 with about 40 hours on it. When the temperature dropped below -10, it had no hydraulics. The fluid wouldn't flow at the lower temps. Sent it in for an early 50hour service a few weeks later when it blew off the hydro filter on a cold startup. The dealer switched out the hydro fluid, no problems after that. I'm not quite convinced that they used permatran for the factory fill.

You talked me into it, thanks.

I don't think they use Permatran for the factory fill either. I know that in the past I have seen farmers try to save a few dollars and buy some less expensive fluid. There would always be some every summer that would be back to pick up some Permatran to change that new fluid out with that had just been in the for a couple of weeks.
What I am trying to say is that Permatran is good stuff and you are better off to stick with it when you change fluids.

While Permatran is a good product, if you stick to Permatran you will also have to stick to the 20-30+ minute warm up schedule in your owners manual for cold weather operation.

Each time you fire it up, and run all that cold, heavy, unable to lubricate well yet, Permatran oil through the pump, for 30 minutes warming it up, its probably not hurting it that much. Or the day when you CAN'T wait the 30 minutes, because you have to go to work, so you only give it 5 minutes and then run the heck out of it plowing the drive, probably won't hurt the trans.

This is the exact reason synthetic oils were developed. because mineral oils thicken and don't lubricate well in cold weather.

Do your own 50hr. service, that way you know your tractor, and you know what is in your tractor.

I recently did the 50 hr service on my GC2310. I put Amsoil series 3000 5W30 engine oil in, plus Amsoil synthetic tractor hydraulic oil. Does it have less friction? Yes. After the change, it would keep moving slowly in the direction I was pushing the treadle pedal when I let go. I'd have to tap the reverse direction side of the treadle. I greased the treadle and now it works properly again. What changed? Only the fluid. Less friction means forward motion at low pump pressure. I'm looking forward to easier starts in our frigid winters, and faster warmups.

Mine did the same thing when I did the 50hr. using Permatran. Greasing pedal helped on mine also but still will coast. Did you find the grease fitting on the underside of the tractor that is not shown in the manual? I use Mobil 1 5w40 diesel truck (Delvec I) in my motor.

First i would like to say, I do use, and plan to continue to use synthetic oil, because of the cold weather benefits.

I have read several posts by people saying their engines run better and have more power, etc., after switching to synthetic. I have not ever noticed any performance difference in anything I have used these products in.

Todays mineral oils are very good lubricants under normal operating conditions.

In order for there to be any difference, there would have to be a significant difference in the lubricity of these products over the products they have replaced. With the exception of the extreme temperature performance, I know of no significant difference in these products to cause the perceived enhanced performance.

 

[DMW]

I agree Ray, but also consider the impoved shear stability of synthetics. They are more resistant to breakdown, allowing the use of multi-grade oils rather than single weight oils. Resulting in the feel of more power, and quieter operation at start-up due to the improved flow. At operating temps, there should be no noticable difference. The dino oils will be near the end of their life at scheduled changeouts, the oil starts to lose it's lubricating properties, and things get a bit noisier. Putting in any fresh fluid will be an improvenment.

I'm also running the HDD in the engine and ATH in the Hydro unit. Been running them since last September.

What grease fitting underneath that isn't shown in the manual? Where is it?

 

[tx2310]

I was thinking it was the brake pivot on the left side under neath, but it is the hydrostatic control pedal that is not called out. There are 2 fittings total. I was 1200 mi. from my manuals.

Thanks Doug - I saw the one on top of the HTS pedal - will look tomorrow for another on the bottom.
