Hurth Transmission Problem

[Chief Engineer]

WOW indeed....just when you t'ink you have seen it all....Presto out pops another nightmare.

[perchance]

I would think that using reverse for forward would be a bad thing since the the bearings and gears are designed to take full thrust from the prop in one direction only ( forward).

I think these boxes can be run either way, the only difference is that the ratios are different so generally the higher ratio (say for arguments sake 2,8 to 1) is used for forward and the lower (2,3 to 1) is used for reverse, helps when needing to stop in a hurry.

The HBW-5 needed forward and reverse clutch packs, one thrust washer and a new damper plate...i retrieved the tranny on Friday and everything is back together, except for the LH prop. I repositioned the shift cable so when the shifter is moved forward toward the bow, the transmission now engages the forward gears.

Any successful experiences removing the barrel bolt inside the Martec hub?? The barrel bolt uses a 1/2" socket, and its integrity is less than desirable. The prop has been rebuilt at least twice, and is ready for the recycling bin if i can't pursuade the barrel bolt out.
