I've taken apart my Eaton 778 pump/transaxle assembly and have completely cleaned the internals..... It seems that the ball piston, pump rotor, motor rotor and brass bushing seem to be the culprit of the problems Bobcat Leo riders have experienced.... I really cannot find any info other that what I listed to be the problems. I CAN get them from partstree.com and the parts amount to about $305. #1716057-Axle Housing Gasket #1726045-Caps-Filter #1716045-Rotor/Ball pump #1716046-Rotor/Ball spring motor I also need the "actuator" which seems to be part # 108240-000 but partstree doesn't seem to carry it..? Also, what weight Hydro fluid do I need? Bobcat tells me 50wt, Eaton tells me 30wt AND i've read 20w50 hydro fluid-(anti-foam properties) Anything else I need to know before putting this baby back together??? Thanks for your help. I know Kiser did this, but not sure if he has had any additional problems since.....?
