Re: [Amel Yacht Owners] Re: ZF25 Transmission Failure

Hi everyone

I’d like to carry transmission cooler replacement as a spare. 
I think the rubber parts, etc. are a potential source of leaking over time and not easy to repair.  Does anyone know where I can buy a set of the right spare parts for the transmission oil cooler?
I understood it’s a Bowman product, but can’t find any reference to order. 

Thanks for any advice.

Hi Duane,

Thanks for that info.  I am planning to address the cooler replacement, at least to carry a spare.

I cannot yet say for certain that the cooler is operating at maximum efficiency, however I am sure we don't have a leak of fluid or any seawater ingress. When we reached shore after the event, I drained 2.05 litres of fluid from the transmission. It looked perfect. I have now changed the fluid about 4 times, and have not noticead any signs of seawater.
I'm fairly confident the biggest source of heat in the event was the brake disk (which is now beautifully polished !) which transferred to the transmission, metal to metal. Immediately after the event, the Volvo temp sensor was showing 80deg which is fairly normal for running at 2000.
