Through my mechanic
I learned that Yanmar
issued a recall
and early SD50s. The front oil seals
are breaking due to excessive pressure built inside the housing. Yanmar's solution is to lower the oil
level in the transmission
. The new recommended level is the bottom of the dipstick. The company is also selling a new dipstick with the new recommended levels.
In searching CF I saw a short thread by captain
Bill started June 30 2010 indicating that very same problem.
Does anyone have more information about this problem?
