Re: 420c steering clutch issue

Hi,

Yes, you do have to drop the track and remove the sprocket to then remove the entire final drive. The clutch pack is inside that along with the brake.

Re: Serial # on JD350 engine - update

Hi,

152 CID is a Diesel. The gas was 135 CID, and lower HP. But, I don't see a HP figure for the gas in my manuals, just for the Diesel. The Specifications pages are a bit misleading, only covering the Diesel as far as HP and torque figures.

Re: Major incident at work today!

Hi,

Yuck. What a mess. Just don't get yourself into a medical issue because someone else hasn't a fully functional brain.

Re: Backhoe weight

Hi,

Given the subject, my brain read 'live cast auction' as 'live cast iron auction'. :P

And, I had a cup of coffee this morning!

Re: reverser oil flow question

Hi, I have also been following, but never having had a 450 I have little to offer here. Well, other than suspecting that the buzzing sound is probably the bypass valve. I recall working with my dad on them in the dealership back in my teenage years, but can't recall one with this particular issue. S...

Re: 1980 JD 350C wont move

Hi, I am sorry, I was thinking Dry steering clutches, not Wet. Dry ones use a pressure plate to make up the clutch pack until the lever is pulled. Wet ones incorporate a valve which sends hydraulic pressure from the reverser pump to the clutch pack to make them up when the lever is forward. And, the...

Re: 1980 JD 350C wont move

Hi, Power flow is thru the Spider shaft (input) of the reverser and straight thru the center when the Forward clutch is made up by hydraulic pressure. The counter shaft is always rotating, but does nothing power flow wise until the Forward clutch is disengaged and the Reverse clutch is made up (agai...

Re: To buy or not to buy

Hi, Yes, the wide track is worth some bucks, so that will help you out in the end if you swap it out. Some folks really need that, and that set look pretty good in the pics. As far as using it, it would work where I live nowadays in NC, in a river valley. This time of year ground is squishy. And, lo...

Re: Equipment gods are in a pissy mood....

Hi,

Man! That is all I can say. I'll say it again: Man! What a day.....

Vegas. Yeah. Only good ones were painted black with gold accents and had a Ford engine. ;)

I remember a time when a lot of Vegas got put on top of 4WD truck chassis with snowplows. :P

Re: Jd 350 recommended oils

Hi, Rollers have bushings with large surface area at each end and a reservoir in the center. It is very important that the lubricant be low viscosity. It needs to flow readily as soon as the roller begins moving. The original viscosity used was not a grease but a heavy oil. No one makes that kind of...

Re: Jd 350 recommended oils

Hi, There may not be roller zerks. Sometime in the 80s, they went to sealed rollers which don't get greased. But, if the rollers get greased, there are ten, five per side. And the idler. And the top roller, which a bolt needs to come out to get the end of the gun onto. That vents the top roller. All...

Re: Jd 350 recommended oils

Hi, Well, we try. ;) Here is another point which I don't recall being covered in that long thread about rollers, greases and guns. On the track tensioner on each side, the manual says you can use a Normal gun. However, it is *very* repetitive regarding the gun not exceed 8000 PSI and to use a tee wi...

Re: LGP tracks and then some

Hi, The image is missing, but I did see them in another thread. Swamp Pads is what I have always called them. They were a standard option. There is a difference at the sprocket end to go with the wide pads. Another bearing you get to lubricate with 90wt IIRC. Those pads like to bend when run on hard...
