We moved and I’m now doing most of the maintenance myself. Time to change the trans fluid and filters in my Hurth ZF 63A transmissions, (Mainship Pilot 34 Express with Yanmar turbo diesel 240HLA-STP engines). The local Yanmar dealer said to switch to motor oil, straight 30 or 40 weight. Hurth manual says to use ATF, dexron III or compatible. Currently they are filled with ATF.
I realize this borders on the which is better questions, blondes or brunettes or single engine vs twin engines but since Hurth has not replied to my query, I ask the group. Keep using the ATF or switch to motor oil?
If there is a thread on this question, I didn’t find it on the site.
Many thanks.
