“Bargain” GC2300 metal in tranny

First real post, seeking opinions. So I am an accomplished tinkerer, have a 13” metal lathe, a Bridgeport, not afraid of a project, but also don’t want in over my head $$$ wise. Bought a GC2300 with loader the other day for $2800, smoking price around me for anything running and moving. Was pouring oil out the loader valve, I had read how easy to reseal.

Tossed $0.30 in O-rings on it, fixed perfectly, oil about 1 gallon down due to the leak, and who knows how many times down before. So I added some old “Premium Traveller” oil meeting Permatran 3. Was feeling all good, ran, drove fine, loader smooth. Rear end pretty good whine in high range, but I’ve heard louder, and nothing specifically to compare to, never on a Massey/Iseki before. Ran out to the dealer, bought 5 Gallons of the new AGCO XL semi synthetic, a filter, O rings for the suction screen. Ran it hard for a good solid hour, and just barely got warm on a 60F day. Drained the sump, about halfway out a heavy PLUNK. 1/4” round flattened, steel something, and smaller bit dropped out. Possibly a flattened ball. Nothing else, drain pan absolutely clean other than a usual fine sheen suspended in the oil.

Then went for the suction screen, and it is BAD, prodigious covering of shavings, both white metal (non magnetic, aluminum case) and some magnetic metallic shavings. Nothing inside the screen though. I vacuumed and swabbed out much, much more shavings from the little mini sump area that screen goes into. I will attach pictures if I can. At this point I put on the $33 filter but filled with the cheapo Traveller, not the $20/gallon AGCO. And it is actually quieter and smoother, again a bit of whine in high range at high speed only.

So anybody want to stab at what I’m seeing, I fear highest bearing that would have lost lube first seized, has been spinning eatings it’s housing bore. Nothing leaks externally, both PTOs run smoothly (though I have nothing to put them under load), 4wd works, diff lock works, brakes seem weaker than I’d expect, but again only one I’ve driven.

Do I

1. Cut my losses and sell it as is or trade up at a dealer,
2. Run it till it blows
3. Perhaps pull the PTO housing cover and try to scope it a bit looking for source.

It shows 537 on the 3 digit clock, so who knows, 1500, 2500 hours? It is ugly as heck, needs a $167 headlight, $150 in grill pieces and hood repainted just to not be embarrassing, but I still feel it was worth the chance. I just don’t want to run it till she blows if somebody knows, yeah it is just the xxxxx bearing you could replace and the xxxxxx housing.

Many thanks.

Re: “Bargain” GC2300 metal in tranny

The screen, about 20x this I suctioned or swabbed out of the little walled off “sump” it sits in. And the round thing, the only thing that came out of the true sump.

Again any opinions, Thanks in advance,

John

Re: “Bargain” GC2300 metal in tranny

Are you still seeing hydraulic fluid leaking? Are you experiencing a loss of power with the loader since the attempted fix? The hydro pumps will whine a little bit when at high rpms. Obviously metal parts in the filter is not good sign but it should mean that the filter was at least working and kept the rest safe.

Re: “Bargain” GC2300 metal in tranny

Oh no 4 buna-n O-rings from a 20 year old $5 HF set fixed the valve completely, no leaks, loader smooth, scoops a full load of gravel high and fast, a bit too fast for my liking actually. Pump is very quiet, sitting still the whole rig is smooth and quiet, only at high flat out ground speeds in high range do I get what I would think to be diff noise, not even hydro noise as in low range but same RPM it is pretty quiet moving. That noise and my subjective feeling the brakes are pretty weak are the only obvious issues.

Re: “Bargain” GC2300 metal in tranny

Build year? Before 2006 the pump shaft was to short causing the spline to strip
2K repair @ dealer
Seems there was a class action law suit on this

Re: “Bargain” GC2300 metal in tranny

It is a 2005 actually, this is the main hydraulic pump input shaft? The pump appears to come off the housing independently, so that would be an easy place to start...

Thanks,
John

Re: “Bargain” GC2300 metal in tranny

The brake is for parking, not stopping. If it isn't locked down with authority, the hydro can easily overpower it.

Something is chewing up the case and the only way to find out what is to take it apart. From the description, the tractor has been used hard, and one way to use it hard is with lots of ballast for pulling a heavier than normal load. The resultant high axle torque load may have broken something in the differential that is now chewing up the case.

I pulled the same stunt with my GT and broke the 4 bolts holding the differential carrier together. The heads of the bolts chewed up the case and just missed chewing up a bearing. The repair bill for that was $275 in 1986 and worked well for another 20 years.

There's a TSB on it, plus the class action law suit
The fix was to install a new gear with a longer splined shaft

Re: “Bargain” GC2300 metal in tranny

Thanks guys, I see the pictures of the stripped splines on several forums now. Though interestingly it isn’t clear if the 4265224M92 pump actually has longer splines or not, it is said to but unclear. It sounds like the case bearings on the associated gear can also be damaged, and then of course the driving gear set is also very high in the case and splash lubricated so I’m sure being a gallon down ? several times hasn’t helped.

I think I will pull the pump tomorrow evening as a first look. I don’t think this explains the large bit that plunked out of the main sump drain, looks to me like there is some internal baffling, so perhaps junk from the failing pump/gears stays forward, maybe if I ignore the plunk bit I can get off just pulling the forward cover. But as the pump, gear, bearings look to go $6-700 I have to think carefully.

Thanks,
John

Re: “Bargain” GC2300 metal in tranny

Well got the pump out, not counting the hours of pressure washing, getting it into my shed, taking it back out to pressure wash again after pulling the floor and realizing how much more needed pressure washed, I figure about 3.5-4 hours for me a novice at this tractor to get it out. And on having pulled, the original paint, never removed pump at either 537 or very possibly 1537 hours out, it is...

PERFECT.

Absolutely perfect. Original pump, original “short” gear with 12mm or so engaging and perfect, splines barely burnished up a bit. Which makes sense as I couldn’t see this as the source of the aluminum shavings. So back to square one. I’m going to pull the rear PTO cover first and bore scope about, then probably end up pulling the hydro, and the front cover in situ. Unless as I still fear the brake is the issue, at which point the side cover looks like it has to come off and the whole tranny probably needs pulled.

I’d like to shout out to Gerry at a White Horse Distribution as looking for the pump, most price it at $375-450. From the P/N he was able to cross to the current Shimadzu number and would have had it to me around $250. For posterity I will post the PN crosses but nobody hold me to these.

Shimadzu GPY-10R708 (470) though those last 3 change, unsure if any meaning
Massey 4265224M91 or 4265224M92 unsure of difference
Iseki is 1725-508-320-00 (unconfirmed but pretty sure from other markets)

Current cross to the GPY-10R708 is per Gerry

Shimadzu GPY-10A1S1-R495

Same pump on CG1705/10/20 as far as I can tell BTW.

Hope it helps someone.

John

Re: “Bargain” GC2300 metal in tranny

Oh and a pic of the pump and original “short” gear. With the new gear the female splined portion in the bearing would be sitting about 5/16” proud of the inner bearing race to increase engagement on the pump splines. If I find something salvageable to fix, I will go ahead and order and fit the new gear (around $110) but not till I’m sure I want to put money into this beast.
