Doesn't the fill cap have a vent in it? Did you block that vent or replace the cap, to ensure that tall the intake/exhaust went through the dessicant?

 

[SpringHollow]

Yes, but mine was plugged already by crud. When i redo my cover, i will relocate the fill port and put on an unvented cap.

I have been reading some older forums on pumps and so forth and have read some people changed their hydraulic oil to UTF and other types. I am wondering if this might be a good idea for me since I already drained the oil and it will need a filter change as well. So how many of you have done this to your Power Tracs? (change the oil that is to something other than motor oil)

Thanks

 

[SpringHollow]

From my recollection of UTF from when i had traditional tractors, UTF seems pretty thin for this purpose.

Dear Ken,
You are right. As covered here extensively in the past, UTF tends to be 10W20. You can get heavier weight versions that are 10W30, and some synthetic versions.

I looked recently for 10W40 UTF and couldn't find it.

If anyone knows a source, I'm all ears.

All the best,

Peter

DieselPower would be someone to talk to but I believe he only had up to 10W30 in UTF as well as straight viscosity hydraulic oils.

I would love to get away from a detergent oil and go with a true hydraulic fluid that does not emulsify water.

If you don't have a good reason for changing, don't. If someone can persuade you about the benefits of a different/better fluid, then it might be worth considering.

Does anyone know what the viscosity level that we should be using in our Power-Trac?

Is everybody using 10W-40 for hyd oil, or a synthetic equivalent?

Read this.

Hydraulic Fluid Viscosity

 

[Bob999]

I have concluded that a wide range multi viscosity oil is best for the PT. Ideally the low temperature rating will be a 0W or 5W to allow free oil flow during initial start up in cool or cold conditions--this is desirable to minimize the possibility of cavitation. The high temp rating should be 40 or higher to maintain power during hot weather operation. I have never found a UTF that has the appropriate viscosity ratings and have continued to use motor oil--presently I am using a 5W40 synthetic oil. I think some have gone to 0W50 synthetic oils.

Just to make it clear, I store my PT in a heated garage that rarely goes below 60. So I think the 15W50 is probably OK. Other garages may not provide this protection. A little more detail on the garage. It has two walls in common with the house, and has ICF outer walls (R50 equivalent) with an R11 door. The attic insulation is R55. There is no actual heat source, but losses from the house do heat it pretty well.

Thanks J_J I read it all. I think I will just keep the standard oil in the system.
BobRip I to have an insulated garage and I don't think it ever gets under 47-50 degrees in the winter. So my PT is not to hard to start in the winter. I called PT today to check on the pump and they told me my "swash coupler broke loose and smashed into the pistons and broke them to". I think that is how they said it, I probably got that wrong. I was also told it was a basket case. It will be finished tomorrow and shipped back to me. Terry told be everything was isolated inside the pump so nothing should be in the lines but I should change the filter to be safe. It was only the 2nd one they have seen broke this way, he said they're a tough little pump (Hmmm mine wasn't). But it will be fixed woohoo. Now I have to put it all back together. Thanks everyone for the help and insight.

 

[ponytug]

Hey, that's a great prognosis. Pretty much all the debris should have been contained in the crankcase for the pump.

Good luck,

Peter

Hey, that's better news than we expected. Hope it goes back together easily for you.

coolconnection did they give you a cost estimate on the repair or replacement pump? In my pt I have rotella hydraulic oil in mine now in the hydraulics, it seems to do the job. I don't know if that was a good choice or a bad choice, but it hasn't caused any adverse effects yet.

They put it under warranty repair. I am so glad of that I don't know what it would have cost otherwise. Also I decided after reading many threads on this that I will just stick to the 10w-40 motor oil in my hydraulics.

I know this probably isn't the right thread for this but I have 1 PT filter left. Did any of you find a good filter in the 10 micron range that fits and works well other than the PT filters for a PT 425? I would like to find one locally and the TSC filters I found were around the 25 micron range so I don't want them. If you have found any where did you find them? Any help is appreciated. Thanks

 

[ponytug]

I get mine (1445) at Napa, but I don't know the number for the 425. You might ask Terry.

All the best,

Peter

When I did a search I found the following:

I have found different hydraulic filters are available locally at farm equipment dealers. I am currently using a purolator H32010 filter for the hydraulics, purolator assured me it is a 10 micron that power trac recommends. The original hydr. filter on my power trac 422 was a gresen K22001. I have not been able to find replacement oil filters for the robin engine in my 422 , but I can buy them from a local garden tractor dealer.

here it is, sorry for the delay!T
NAPA 1551, make sure it is rated at 10 micron.

 

[ponytug]

Bob- that's the Napa filter that my 1445 uses. Maybe one size does fit all...

By the way, the 1551 is a 10 micron filter; the 1553 would be the 30 micron equivalent.

All the best,

Peter

Thanks, I will look some of them up. I just use regular oil filters on my 25 hp Robin engine. I am using a Walmart cheapy. Those cheap filters at Walmart I think are AC Delco or something but I know they are not Frams. I change it every 50 hours religiously. Here are some cross referenced #s I found for the filters: STP S4967, Fram PH4967, fleetguard LF779, wix 51394, AC Delco PF-1220. I talked to a few people and found that there is really no difference in lawn and garden filters to the automotive ones. I have used them for years. I don't want to spend $12 on the same filter I can get elsewhere for $4.

 

[SpringHollow]

The 1850 takes a Wix 51759.

My 1845 takes the Napa 1759 (Wix 51759) which I think is a physically larger filter than the 1551. I would have thought the 1445 and 1845 would use the same hydro filter.
