Hi, A low pressure gun will stop pumping once the bellows seals hit the end of their travel. A regular, high pressure, gun will blow them out and ruin them. The idea is the light No 0 grease (or heavy oil) will push out as you operate the machine and carry the dirt away from the inside of the roller...

Hi,

Fallston, NC is a 3 1/2 hour drive for me. There might be someone closer.

Hi, There is no photo hosting on this site. Not directly. As already mentioned, use another photo hosting site and then link to that. We do have a site many of us use, one that is easy enough to use and is free. Here is a post on how to use that: http://www.jdcrawlers.com/messageboard/viewtopic.php?...

Hi, 57 would make it a 420. There are quite a few differences between a 420 and an MC. Such as a 420 has a water pump and an MC does not. An MC would be a 3-roller undercarriage only as well. Most 420s have a 5-roller with the 4-roller being an option. You would have to get it going if you wanted mo...

Hi,

Here you go:

It is a Dresser document. Applies to pretty much everything out there. Adjustment details for specific machines are in the various service manuals.

Hi, That would be me. Multiple crawlers, one at a time mostly, and none of them cheap. Either Pay High for a good machine and pretty much just have it work. <OR> Pay Low for one and then watch the same amount of money a good one would have cost you dribble out of your wallet while you do a lot of ha...

Hi, One odd thing about the changes in 1973: Deere decided that the 4030 was to be the replacement for the 3020 and not the 4020. The 4020 replacement was to be the 4230. That caused confusion, for sure. I recall 4030s being returned for 4320s at out JD dealership back then when farmers figured out ...

Hi, Last year, for my wife's birthday, I bought her a brandy new JD 3025E wheel tractor with a front end loader. Deere had a zero percent financing offer you see. And, she has issues with her left leg and can no longer use the clutch pedal on my 2008 5045D. She needs a hydrostatic transmission. So, ...

Hi,

Ah, yes. Colorful language has magical properties.

Stan

Hi,

Ah. That would explain a lot!

Stan

Hi,

Yep. That's a potential problem with hydraulic lines. They don't immediately tell you when you cross them up. Unlike electricity. That tells you Right Now!

Stan

Hi,

They are also called Rose Joints. I used them by the truckload in racing cars. The entire suspensions used these. We didn't worry about dirt and wear. Those parts tended to not last long before they got whacked. After which we just used all new ones.

Hi, And, the various housings breathe. So water vapor gets in even in the pole barn. Then, the temperature drops and the vapor condenses out. The oil in the old style differential reversers were the worst when it came to having oil that bore more resemblance to The Blob than oil every Winter. Danged...

Hi,

I agree. Skip the Helicoil and go for the insert. I have never had good luck with a Helicoil and never had an issue with an insert.

Stan

Hi,

Nice!

It is 30 degrees here today and yesterday in NC with high humidity and a Duke's Mixture precip. So, I am doing a different kind of dozing.
