the fluid in our borg warner velvet drive. This wouldn't be a huge problem except we are at a remote
island off the East Malaysia
Coast. We noticed the fluid level down after the gearbox
slipped comming to anchor
2 days ago. Topped it up and everything seemed fine. The following day the gearbox
was working fine to leave the anchorage. We shut off the engine
after we raised the sails
so I inspected the gearbox to find the dipstick white and frothy. The cooler has developed a leak and I suspect the fluid was mixing with the water
and being exhausted. Again a fixable problem however we were battered by a severe storm and had to motor
into an anchorage. We had to top up the fluid to run the engine
to make it safely through the reef entrance.
Today we bypassed the cooler and have flushed the gearbox with diesel
to remove as much of the salt water
and ATF as possible. The gearbox was run with the diesel
in it for a very short time to circulate the diesel and it operated fine.
The dilemma we now face is that we only have 1.2 lt of ATF left. The box has a reduction gear
so it's capacity is about 2.5lt. We have managed to get 1lt of Castrol 68 hydraulic fluid from a guy with a back hoe on the island.
The cooler is bypassed so there is no cooling
and will run the box and low revs to get us the 35 miles to Pulau Tioman were we may be able to get help to replace the cooler.
After the long intro my question is 1. Is 1.2 lt of ATF enogh to get us out of trouble or 2. Is there a major problem mixing the castrol hydraulic fluid with the ATF to get us the miles we need to get help. My gut feeling is it will be ok to mix, I was hoping someone may have first hand experience.
