Re: [Amel Yacht Owners] Re: ZF25 Transmission Dipstick / Fluid Level

After reading these ZF transmission threads with great interest, I thought this was an Amel 54 problem, but I've also seen a few posts from folks with Super Maramus, so I went to check mine.  My transmission says HBW 250-3.0R.  According to this manual I found, the HBW 250 is the same as the ZF 25 M.  So I guess this thread does apply to me?  Except none of the numbers you're throwing around make sense -- my dipstick is almost exactly 160mm from the bottom thread on the cap to the mark.  And that manual says I should put 0.75l of fluid in, which seems crazy small and is way less than anyone else in this discussion.  I'm filled to the mark, but looking in the dipstick hole, the transmission is only about half full.  I also don't have an O-ring on the dipstick.

Have I misunderstood the part numbers and this thread actually has nothing to do with me?  Does that manual I found actually apply to my transmission?

Thanks,

Dean,


Hull #69, 2007 A54 has the correct dipstick. I distinctly recall adding 2L per the manual and noticing that it was low, so I added more. No tranny troubles, but I do have that rattle in the throttle you mention.

Do you know if it's possible to replace the filter cover with the updated design? Or does the updated design more about changes to the transmission casing where the filter cover sits?
