1987 JCB 3CX Syncro Shuttle Drive Problem
Posted: Tue Sep 15, 2020 11:06 pm
Help!
If you've been following my Project thread my apologies for the repeat but, after nearly three weeks of fettling to tidy up the cab of my newly acquired machine, fix some leaks and rattly bits I finally got to the point where I could run it up with the plan to get the engine good and warm before doing an oil change. Well, that was the plan, it didn't want to move from the spot where I'd parked it about a week ago.
The only fiddling I have done with the transmission has been to change the output shaft oil seal, the transmission filter and top off with 3.5 litres of fluid that had been lost (2 litres) during the seal change and wasn't in there to start with (1.5 litres). I had moved the steering column shroud during my cab tidy and been wiggling the cables encased within. The shuttle lever and indicator/lights/wiper stalk are a bit loose on the steering column, and since the fiddle I appear to have lost indicators and wipers, I don't think the horn or washer buttons did anything before and they certainly don't now.
These are my drive controls arrangeement:
In addition to fiddling with the steering colum shroud I have also had the front load controls in pieces, but I didn't overly stretch or disconnect the main control lever with the transmission dump switch.
Before I go tearing into the electrics, is there anything obvious I could have missed with the way the machine is meant to operate? I did notice after a little bit of running the 'charge' light illuminated, so could a poor charging circuit or weak battery cause the shuttle or transmission dump system to wig out?
