Help! GC1705 Hydraulics out

I disagree. My fill cap is super tight. I would guess 20lbs of pressure to get it out. It is probably different for each of us.

LOL, Definitely different! Mines tight but not that tight but still, the sight glass "should" be secured well enough to withstand more pressure than the fill cap IMO.

There are glues specially designed for plastic, fiberglass, pretty much any composite to metal. Corvettes are built using the same technology to hold parts of their bodies to the frame. 3m makes the stuff we use, and it comes with a lifetime warranty. We even use it for putting bedsides and doorskins on vehicles. Check it out...3M Panel Bonding Adhesive 8115. You could buy another one and see if your local bodyshop would install it for you. A tube is like @45.00.
Good luck!

Good luck. I'm sure you won't have any problems with it now.

Final update. Everything refilled, pressures checked and I've got it back. Seems to operate fine. I was worried about warranty, thinking I only had till 250 hours, but turns out its 5yrs/2000 hours. So I'm set lol.

They did replace the piece with something different, mechanic didn't know if it was a replacement part #, but did say that "thats the sight glass on all the others" not sure if he meant newer tractors, bigger tractors or what.

The most important thing to me is this new sight glass has a black rubber seal much like an axle seal, I think it will work better long term. Picture attached.

No more H/L mark....

So for now all seems well.

I had them do the 250 hour service, and I picked up some hydro fluid juuuust incase.

Also of note, the mower deck adjustment (not locking in up position when using 3pt) there is a dealer knowledge object, and 2 new parts. They installed at no charge and that's resolved that issue as well.

Mowed for an hour or more last night and speed seemed fine and had no issues. Fingers crossed.

Interesting; that looks just like the one on my old 2310. Apologies for the horrible pic- but mine, under the gray paint, also appears to have that same rubber seal there. And yes, I can just make out some numbers there, just like a wheel bearing/axle seal.

I'm aware this is an old thread, but I had a similar issue with my 2017 GC1705, and I don't see "my" solution listed here, so here's the story:
I was blowing snow with my rear-mounted snowblower, and after I had pulled forward (about 50 feet) to start the next pass, noticed a stream of oil.
I shut down, found the hole where the sight glass should be, back-tracked and found the glass. Called the dealer, he had me pull the fill cap and examine the vent in it. The vent had glazed over with ice, which resulted in enough pressure in the housing to blow out the sight glass. He had me pull one of the bolts next to the sight glass, and get a fender-washer just large enough to catch the edge of the sight glass, it is now locked in place and can't possibly blow out again.
[ On my own advice, I reamed out the vent hole a tad larger, and added a second vent hole on the other side of it. ]
-I only lost approximately a half-gallon of hydraulic oil, so there was no damage to the tranny.
There was no loctite or other sealant on the sight glass, it is just a pressure fit.
