I recently completed a rebuild of a single engine Cat 3208 TA 375 HP with a twin Disk transmission. (Transmission was rebuilt with new clutch and seals, all internal was found to be in good shape)
Not being familiar with this transmission when we did the sea trial I noticed an unusual to me, bang that jolted the entire engine when it went in gear, both forward or reverse. The damping plate was also rebuilt.
Thinking there was something wrong, the mechanic that rebuilt the transmission connected his pressure gauge and these were normal. He contacted TwinDisk and they told him this was normal, they verified this with an email to the subject.
My previous boat had an electronic ZF and these engaged very smoothly.
Anyone with these engines have an opinion?
Thanks
