Re: Transmission issue am stuck many miles from home.

Thanks all for your help.
We got a local man experienced and resourceful, problem was quickly identified at the output shaft, this enabled us to only take off the gear reduction part.
Inside we found that the coupling nut had come a bit loose, the worst damage was the coupling fixed to the output shaft by a spline and the had been completely worn (chafed) down to nothing.
We were anchored, unwilling to use the dinghy to push us into the mariner due to minimal keel clearance. Feeling vulnerable.
We are repaired now and ready for expected 60 Knot winds today on east coat of Tassy.
Local Fish and chip van as mentioned by Chiefcoxain is indeed a treat and social epicentre.
Attached Image is the offending coupling.

Bit of history, I topped up the transmission oil about 100 Eng Nmiles ago with Engine oil as that was the best advise, it was at or below dipstick bottom.

Had a local Fisherman who suggested, broken drive to the Hydraulic pump. Looks like it will need to come out, we have help coming tomorrow, hopefully we can do it in a day and he be Goffa for parts.

Suggested to owner that I could plot a qtVlm course non-stop, but he not interested. Anyway, I will identify and inform what we find.
Engine oil! Did I read that right?

You might get away with that in a pinch but you'll need to keep the load low and the duration short.

Engine oil cannot maintain the thin film friction within the tight tolerances required of a clutch and band transmission.

If you have indeed used engine oil then drain it and replace it with atf or hydraulic oil. There is a reason the manufacturers specify a limited range of oil options.

You may have good pressure but no drive with engine oil. You will often experience a lot of slip from the bands and chatter from the clutch discs if it doesnt like your oil choice.

If you gave used anything fancy like a synthetic oil then a full rebuild (friction elements) may be required. OTOH ypu may be lucky and be able to drain and refill with no ill effects.

BTW the velvet drives aren't designed to run in reverse for extended periods.

Re: Transmission issue am stuck many miles from home.

Hey LeftBrain.
We got advise that Engine oil is Ok, but I sourced the manual for this Engine and they say SAE10 but didn't mention ATF. Anyhow thats what we did after the problem, complete change to ATF. Then I noticed that the oil seal was damaged.
After the engine was boxed up refilled with ATF SAE10. Anyway, the damage is outside the lubricated part of the gearbox.
This transmission has run quite happily for many years with Engine oil in the Gearbox.
I noticed you have a Liberty 458, I sailed one across the Indian Ocean, interesting trip, so I always read your threads.

Cheers
Oceanrider
