Hi All, After mowing for a couple of hours over the weekend I noticed a small amount of oil leaking onto the foot rest pan next to the HST operating pedal. I followed the oil leak back up through the rotational valve area to the top flange (the area above and to the left of the rotational valve with two bolts or hydraulic take-off ports on top). The oil appeared to be coming out from between this top flange and the rest of (or lower part of) the hydraulic housing - I can see what looks to me to be a seal inbetween the flange and housing. Has anyone had an oil leak from this area before and is it a simple matter to remove the top flange and replace the seal (do those two top bolts hold the top flange onto the housing?) Thankyou.

Sorry I can't help with you question but there's a good chance somebody here knows the answer. I would check the fluid to see that's it's not overfilled.
For myself, I don't think it's a good idea to do even simple appearing tear-downs without a repair manual. For example, in my Ford manual there's a warning about taking off the transmission top-cover. Part of the safety switch can drop off and into the TX, where it would be a big problem to retrieve. I wouldn't know that except for the manual.
You're likely looking at a gasket rather than a seal. Most times I've ended up tearing gaskets when taking things apart so I'd want a new one on hand for a tear-down. The trick to getting gaskets to seal is very clean mounting surfaces. I use grease but there are special sealers. ....

Thanks for that info Tom - looks like I will have to resort to the manual in any case. See you next time. ....
