I finally put my 73 SIII on the road yesterday and took it for ride. Most everything went well and operated as expected. Having not spent many hours driving one of these vehicles I have one question. How loud should the gear noise be from the transmission / transfer case , overdrive? I understand that there isn't much sound deadening material between the cab and the gears, particularly without the middle seat in place. There is quite a bit of gear noise.
Secondly I definitly have a problem of some sort and this could be related to question 1. When moving slowly 1st / 2nd gear during the transition of going from an engaged clutch to and engaged clutch there is a clunky sound which sound like it is coming from the overdrive. I had a friend take a ride with me, removed the cover plate and listened to the sound. It seems to disappears when the clutch is fully engaged or fully disengaged. I'm sure thes sounds could be heard here but be from a differnt source.
During my rebuild I did not disassemble the transmission, transfer case overdrive units. I did replace all the shaft seals, input , rear and forward drive shafts. I did seperate the gearbox from the engine. I also have trouble running in first gear at a steady slow speed. The truck wants to surge/buck with the clutch disengaged. This problem is not present when doing any accelerating or engine braking (load on gears).
I was thinking of removing the overdrive to diagnose if that is the problem. I'm not sure what replaces the overdrive at the rear of the gearbox if it's removed.
thanks in advance for any suggestions.
