Re: Diagnose the problem??

Hi, Yes, that screen gets a lot of folks. IIRC, it is one of those things not in the 420 service manual, but in the M one. They wrote those sequentially, of course, but expected a service shop to have all the earlier ones. So, some info is not repeated in later manuals. I have the M, 40, 420 and 440...

Re: ‘79 455G - breaking tracks

Hi, Now we can get into US Gov't TLAs: Three Letter Acronyms. Like NASA. National Aeronautics and Space Administration. Except, they get four letters because they are more advanced than the BLM. And, a true acronym since it is pronounceable. Not that this requirement for an acronym would bother anyo...

Re: The Kendall Diaries - Motor Oil

Hi, As I enter these sections, there is one which addresses additives. And, the detergent is one. It holds the byproducts of combustion in suspension. It is why the oil turns black. When it becomes fully loaded, you change the oil. These particles are all too small for the filter to trap. In the old...

Re: Diagnose the problem??

Hi,

Don't forget to pull the plug on the bottom of the carb and drain the bowl into a pint glass jar (so you can see what comes out). Also, there is a screen as part of the fitting at the carb inlet. Pull that fitting out of the carb after pulling the fuel line and check that screen.

Re: jd440ic.distr caps

Hi, I don't know if there is a 4-cyl cap which fits. The thing is keyed. Is the keying different than anything else? Anyway, the keying prevents reversing. Not that it matters, the most wear occurs on the center contact. And, the main reason I have had to replace a cap is the thing cracks. I don't r...

Re: Saving transmission oil?

Hi, I have a document from circa 1980, from Kendall when they were owned by Witco: Lubricants and Hydraulic Fluids - what they do and why. It was written by the late father of a long-time engineering cohort of mine. He was VP of R&D at Kendall, and later Quaker State, until he retired. I have a lot ...

Re: Saving transmission oil?

Hi, 15/40 base stock, the part which is made from crude oil, would be close to hydraulic oil. But, the additive package, the mix of stuff added to the base stock, is quite different. Especially the anti-foaming agent, which hydraulic oil has more and better of. The engine oils contain detergents to ...

Re: Saving transmission oil?

Hi, I replied in your other thread that I think you have an oil problem. If that is 15/40 in there it is way wrong. And, even if it is something labeled 303, you are still in trouble. All that stuff is garbage. Banned in some states, but unfortunately not in all. Go to a Deere dealer and buy some ac...

Re: JD 455G Loses Drive

Hi,

My guess is that you have an issue with the oil itself. So, go to Deere and buy some actual Hy Gard and change the oil.

Re: 420 oil filter ?

Hi, First thing I would look at is a Number One filter from a Ford. They usually have a number one in most filter makers part numbers, which is why I call them that. They were the most common adapted filters. I used them on my racing cars as I liked remote mounted filters. I have even used them on m...

Re: Water in 440IC

Hi,

Water probably came in the exhaust as rain. These things need a can over the stack when parked. I do this even in the shed in case of a roof leak.
