After starting problem appeared we did have generator rebuilt and got new regulator. Impact of wheel coming off only change we know between easy start and now hard start. Shut off and still won't restart when warm even with ether (or a propane blow torch), but will after cold with ether. Adjusted fuel pump timing for best running. Started with ether - individually loosen all injector fuel lines and motor ran rough until tightened injector. Thought something to do with fuel so rebuilt fuel pump - no change: replaced fuel filters and ensured all fuel lines open - no change had it rebuilt again professionally - no change Checked compression while trying to start: 260-275 all 4 cylinders vs supposed to be 400 when warm and running 200 RPMS so don't know if 260-275 is good or bad? Motor kept running fine but after turning it off it would not restart after replacing front end/hubs - unless we used ether. While moving to re-attached backhoe front wheel lugs popped and wheel came off crashing to concrete. My 1969 Case 580 CK 188 Power Shuttle diesel won’ start unless cold and then only with ether.Īfter redoing the heads, this tractor would start easily even with weak battery whether cold or hot.
