Re: JD350 crawler loader engine

Hi, Yup. 1020 used the 3/152, 1520 used the 3/164. There was a second coming of the 820 that used a slightly smaller 3 cyl in both gas and diesel. Then the 1520 became the 1530, then the 2040, and, well we all get the idea. It kept on, eventually becoming the current 5045D with a 3/179 turbo. And, t...

Re: JD350 crawler loader engine

Hi, Your dealer guy there a Yellow one, or a Green? If Yellow, I can see where he might say that. I don't recall they used it in anything other than the JD350 series. The essentially same engine is still in the 5000 series machines at every Green dealer, everywhere. Deere has made so many Green mach...

Re: 40 Crawler Track Locked Up

Hi, A crawler has no differential. It has a spool where the spyder gears would be in a wheel tractor differential. A 40c has steering clutches which are made-up until you pull a lever back to release a clutch. First, the clutch releases, then the brake applies. If one brake band is stuck, neither tr...

Re: Early 1010C, 115 gas engine

Hi,

Not only does Lavoy sell parts, he sells proper parts. Dig thru the forum for stories of improper parts bought online from other sources. Such as steering clutch discs that shatter almost right away....

Re: 1959 John Deere 440 clutch replaced, issues afterwards

Hi, Upon re-reading, I wonder if the brake and clutch pedals are binding. They are of a rod inside a tube under the trans case. Sometimes they gunk up such that they no longer move freely. Then, the brake pedal winds up applied when the clutch pedal is depressed. That limits the clutch function and ...

Re: 450C Dozer 1974 Alternator Troubleshooting

Hi,

I would just replace it with a more modern one with integrated regulator and cutout. What is usually referred to as a one-wire alternator.

Re: radiator cap bfor jd40s

Hi, No, they aren't pressurized. Thermosiphon system, so no water pump. Pressurizing will restrict the natural flow of water and cause overheating. You could use a pressure cap and drill a hole thru the center. But, then it won't have the copper wool packing which keeps the water from spitting out t...

Re: 1959 John Deere 440 clutch replaced, issues afterwards

Hi, Well, your 440 might have issues with five clutches..... The first is right behind the engine, a single-disc master engine clutch. The second and third are inside the direction reverser. One clutch pack for forward and another for reverse. By the sound of it, yours is kept in forward and you use...

Re: 6405 Dozer

Hi, There was a point in time when they quit sticking serial number plates on the dozer and loader frames. They then added an extra letter into the machine serial number string to indicate what they put on at the factory. Like 350BA and 350CE for example. I think the A meant bare crawler, and the E ...

Re: Missing voltage regulator on my JD 450C

Hi,

Yes, it is quite common to install an alternator with integrated regulator when the old one with external regulator quits.

Re: 440 Track Adjusters Hydraulic vs Screw type

Hi,

Manual ones require a lot more time to adjust. And, crawling under the machine to get to the inner ones. Also keeping track of how much you move each one as you need to do both inner and outer the same. Hydraulic ones are just pump from a grease gun.

Re: Here comes another Hurricane

Hi, Here in Lillington, which is 30 miles South of Raleigh, Florence didn't wind us at all. It didn't even flood us here more than usual. The Cape Fear river was four feet lower than Matthew. Eight feet lower than Fran. But, six miles downstream where the Upper and Lower River feed the Cape Fear, it...

Re: New 450B purchase, worth it?

Hi,

Backhoes run off the crawler hydraulic pump. Hoe crawlers have different plumbing than non-hoe crawlers. The main lines pass out the back to the hoe and then to the blade/bucket controls. If you remove the hoe, you have to attach a jumper line across the hoe connections on the crawler.

Re: Did all 350s have a Rops

Hi, At the start, none had ROPS. Then, they became an option. By the end, they all had ROPS. This doesn't follow the sub letters, and I don't know the years when the changes occurred. I can tell you that my 68 Straight did not have one, and my 78 C does. So, somewhere during that 10 year stretch ROP...
