I have a 4Z 943 that is new to me. We ran it about 5 hours and evrything was functioning fine. It appeared it had not been serviced in a while so i had some of my help service all of the filters and fluids. Upon restarting we have what seems to be a major transmission issue. When the travel lever is in neutral the machine runs fine but just as soon as you attempt to shift to forward the engine stalls abruptly almost like the transmission is locked down but when we shift to reverse it does not react at all.... no travel, no stallining or anything. I quizzed my guys about everything they did while they were servicing the transmission filter. Here is the rundown below...
..As they were raising the cab something happened and they accidently broke the front cast iron lever on the transmission that connects the linkage to one of the steering pedals. I couldn't get to upset because they were having to use a forklift and straps to raise the cab since the hand jack wouldn't work. I brazed it back together and reinstalled the control lever. The lever appears to be back to it's original shape but if it is not I can see where this would possibly put that pedal linkage out of adjustment.
My guys said that aside from that mistake everything else was straightforward with the filter change and lowering the cab back down. I looked at the travel lever linkage and all 3 pedal linkages and they all appear to be connected correctly. I really dont see anyway to reconnect them incorrectly. I am going to raise the cab again in the morning but I'm just hoping one of you guys can shed some light on what we've done wrong. I saw a link Nige posted about manuals and I am about to order the OM download from Cat's site in hopes that it has some descent pics of the linkage positions and adjustments so we have something to start with in the morning. In the mean time any help is greatly appreciated. Thanks again guys!
