Re: Now have a 78 JD350C

Hi, Well, she still runs ok. Compression is a little low, so she doesn't have the power she used to have. My main concern when it comes to really using it is the coupler between the reverser and the trans. It has a bit of slop I can feel when changing directions. To get to that requires pulling ever...

Re: Now have a 78 JD350C

Hi, It is OK. Not everything needs to be a Deere. ;) Mark only had to take the 350 apart as far as the water pump. So, who knows what was done to the reverser by someone else. Probably nothing. He did change the reverser oil and filter and eyeballed inside as best as one can. It operates just fine, ...

Re: 6 volt change to 12 volt

Hi, I forgot about the ammeter. Yes, it would read backwards. Won't read charge at all if one runs a wire from an alternator to the battery, even though it is charging. Will still read discharge in that case because machine load (ignition, lights) still will come thru the ammeter. Well, read charge ...

Re: 350 diesel running rough and smoke

Hi, The timing marks on the IP are under a solid cover, not glass. Remove that with the engine turned off and you can see if there are little bits of plastic which look remarkably like mouse turds. The cover normally gets removed to set the engine to TDC on #1 prior to pulling the pump or to adjust ...

Re: 6 volt change to 12 volt

Hi, The 420 gen was two-brush with a 2-bobbin regulator behind the tin dash plate. The M was a 3-brush gen with a 1-bobbin cutout relay behind the cast iron dash. Someone must have changed that one out for an older one somewhere along the line. Yes, you can move the 3rd brush to get to 12v as long a...

Hi,

True. Someone could have repolarized the generator to negative ground.

Re: 350 diesel running rough and smoke

Hi, "Mouse Turds" are easy to spot once you pull the timing window cover on the IP. What they do is plug the return line from the IP to the tank and that screws up the fuel flow and fuel binds the pump. Easy enough to clean out, but that danged ring will keep on falling apart and plugging it up agai...

Re: 6 volt change to 12 volt

Hi, Original would be positive ground. All 6v were positive ground. Early 12v were pos gnd also, but shortly changed to neg gnd. I recall a 47 Ford fire truck we had in the local dept which was 12v pos gnd. It may have been that 12v began on industrial equipment much like 24v is used on some stuff t...

Re: jd440ic charging issues & hyd cyl issues

Hi, Yes, that is correct. The 420/430/440IC used the same cam-driven gear pump. The issue with too high a relief valve setting is it will distort the pump in some manner. The gears and housing all have little clearance by design and overpressure has to distort something. At which time the pump press...

Re: The Dipstick Diaries

Hi, And, another...not quite Dipstick in nature, though. I decided to drop out the oil in the 350C trans and finals. Smelled a little old on the dipstick. You know, a slight odor of mustiness it gets. No big deal, right? Well.... The drain plugs on both finals 1/2" pipe with the usual square hole fo...

Re: 350C Op Manuals

Hi, Just an update. I see one item that doesn't match. The late OM shows the later hydraulic tank with associated spin-on filter. My machine has the original style tank without a spin-on filter. So, that is pretty glaring. I expect each OM has updates as they changed little things like this. Doesn't...

Re: The Dipstick Diaries

Hi, So, now I have this nice 78 JD350C with an outside blade to keep Dad's old 420c company. I finally fixed the 'I wish I hadn't gotten rid of my 68 straight 350 when I moved' issue. This gets the venerable 420c off the hook for larger jobs and the 350C makes ditch work on my mile long road easier....

Re: PTO shift lever

Hi,

Unless, you have a spot with lots of little trees. They will hack with a bush hog, but leave sharp little stumplets to poke at your tires. Enter the crawler with PTO. No worries there! Even if you have no 3 pt, use a trailing attachment to the drawbar. :)
