Help keep from being stuck at sea by following this simple guide
In previous Tech Tips, we have written about the care and maintenance of ZF/Hurth transmissions. These Dr Diesel Tips have focused on the correct lube oil to use, our innovative stainless steel oil coolers, damper plates etc. See, for example:
- Tech Tip #22, Hurth Gears: Their Care and Maintenance,
- Tech Tip #54, Marine Coolers and Couplers,
- Tech Tip #78, Hurth Marine Transmissions: The Ins and Outs of Basic Maintenance, and
- Tech Tip #96, ZF/Hurth Transmissions: A Six Step Program.
We have also written about ZF marine gears in our more informal Tech Tip Series. See, for example,
- Tech Tip #2, Marine Transmission Fluid,
- Tech Tip #47, Avoiding Idle Gears, which originally appeared in National Fisherman, and
- Tech Tip #59, ZF/Hurth Marine Gears: Coupler or Damper Plate 101.
But this Tech Tip is different. It offers a note of caution.
When sailing or when being towed never leave your Hurth mechanical transmission in the “Forward” position. This puts an unacceptable strain on your Hurth marine transmission. Transmission damage will result. To avoid this you can lock the propeller by putting the gear shift lever in the “Reverse” position or leave it in the “Neutral” position and it will free wheel.
