JCB 3cIII gear box Help
Posted: Mon Nov 27, 2017 1:48 pm
Hi All, just registered with this site as there seems to be some really knowledgable people on here and I am struggling to find any info on a google search.
I have recently purchased an old 3cIII late 70's i guess. It is the model with the torque converter. When I select fwd or reverse it takes a fair while for the gear to engage, then once engaged it will sometimes drop out of gear once it has started moving. I am guessing this is due to oil pressure or lack of oil. Can any one guide me on how this system actually works, is it a seperate hydraulic system for the drive? and if so where is the fill. I have a pipe that connects to the gear box that comes up in the cab floor. Like I say I have tried to download manuals etc but can find very little. Any help would be greatly appreciated.
Thanks , Tim
