Larry 1 #1 Posted April 24, 2014 I have a leak that I haven't been able to locate for a few years. I solved a good bit of the problem when I found the plastic fill tube had cracked adjacent to the threads. I replace that with a length of iron pipe cut to length and ground flat for the dipstick. But the tractor continues to leak near the hydro side. What is the most common place for a seal to fail? Does the hydro have to come apart to replace seals? I think the axle tube seals are okay.

MalMac 1,331 #2 Posted April 25, 2014 Best thing to do is get washed off good (power wash) that will allow you to see where the oil is coming from or at least a general area. A little oil leak can go a long way on making a huge mess making it difficult to locate where it's originating form. Share this post Link to post Share on other sites

Craig Arndt 6 #4 Posted April 25, 2014 My leak was coming from a couple places. There is a red colored metal hose running below the fan that was misting out oil. I put a white liquid teflon paste on it, took care of it immediately. The other leak was coming from a black hose behind the fan that was on a swivel type adapter. That was fixed I believe by replacing the rubber o-ring with a nitrile o-ring I bought a box from Harbor Freight. I am still finding some areas I may be misting past the seals, but the leaks are gone. Just have to know I need to routinely clean the pump fans and fan so it stays cool 1 Share this post Link to post Share on other sites
Larry 1 #5 Posted April 26, 2014 Craig, I suspect that metal tube just above the input shaft. Was that difficult to service? What has to get off? I had to replace two of those rubber hydraulic lines a couple of years back due to leaking. I had to have one made locally from parts because Toro was out of stock and it was middle season. The commercial fittings aren't tidy 90* pieces either, they have a long sweep. It was a nightmare to install. I have leaks at the deck control valve underneath too. That is really hard to work on with all the hidden fasteners that should have had captive nuts! There's a bit of oil from everywhere. I'm trying to get the worst ones.
