Oliver 77 Diesel Transmission
Here is an interesting transmission and final drive from a 1952 Oliver Tractor. We split this thing in half and are in the process of overhauling the entire tractor. Nate sandblasted all of the components and inspected everything, cleaned out every thread and ordered all new parts to make this tractor like new.
Everything worked well on the tractor but when we took the transmission and final drive apart, every bearing was severely worn. Nate cleaned the case and replaced all of the bearings. The transmission has 6 forward speeds and two reverse speeds. The pinion turns a conventional looking differential which has drive gears to turn the large “bull gears”. This such a nice layout, in fact, every component is so well thought out and rugged that I am thinking of changing from working on classic sports cars to tractors!

Nicholas.
A knocking noise that is audible only in a specific gear usually means that there is a bad bushing on that particular gear set or a chipped tooth on that gear set. We are about to disassemble a Ferrari transmission that has a second gear knocking sound and will do a blog post on that job in the next month or so.
