4020 crankcase capacity

[tarzangun]

Can any one tell me how much oil the john deere 4020 diesel takes? It is a late 1968, 4020 and my manual says that it takes 8 quarts, and so does my I T manual. But my dipstick and my John Deere parts man dis agree. they say 12 quarts.

 

[larryanderson]

The capacity is 8 quarts plus one more for the filter.The 69/72s do hold 12 quarts plus one for filter.You maybe should place a wager with him as you will win.

I'm not disputing but I'm asking. How is it late model 4020's hold 4 more quarts of engine while utilizing the same part # oil pan of early model 4020's? AR63193 OIL PAN 1 (DIESEL) (MARKED R44419 OR R53741) (SUB FOR AR45787) (NLA)

So why the different length dipsticks? the parts book lists two sticks. I would understand if they listed a different oil pan. I have both dip sticks , and one is 2 inches longer than the other. It so happens that the tractor has been running on the short one for longer than I have owned it, and I just recently had the motor overhauled. (90) hours ago. And we are struggling with hard starting, and blue smoke when running. Any chance that too much oil in the crankcase is related? Your thoughts would be greatly appreciated

There are different length dip stick tubes the pans are the same

 

[Tx Jim]

Here's the spec's on the 2 different dipsticks for an early 4020
Part Number:AR40511 DIPSTICK (SUB FOR AR32565 OR AR34917) (USE WITH R41883) (THREADED TUBE)
Description: CAP, OIL FILLER, WITH ROD
Overall Length 11.118 IN
Length - To Full 9.354 IN
Full Mark 0.882 IN

PN AR40750 DIPSTICK 1 (USE WITH R41070) (UNTHREADED TUBE)
Overall Length 13.390 IN
Length - To Full 10.890 IN
Full Mark 0.880 IN

Here's the block #s for the different dipstick tubes
R41883 TUBE 1 (THREADED) (SUB FOR R40603)
R41070 TUBE 1 (UNTHREADED) (USED WITH BLOCKS MARKED R40930, R40940 OR R49550)

With the long tube and short stick they will hold almost 5 galllon oil ask me how I know my 4020 has a late seriall number engine with the new style dipstick not the threaded stlye

Your 4020 must have a Newer Generation 30 series engine or a combine engine. Is the engine oil filter in the oil pan or is it a screw on?

Tx jim is right the later 4020 had a bigger pan as in the deep part of the pan was longer

 

[thurlow]

9 quarts w/filter; have had one ('68 model) since '68....in addition to several others. Have never changed the oil without changing the filter.

 

[msb]

If memory is not failing, you can add 2 additional quarts before the rods start dipping oil.

 

[4020deereboy]

Filter in the pan. I bought the engine from a salvage yard
and completely rebuilt everything On the engine I just went
by the full mark on the dipstick. Bad bad idea! We never had
an operator manual for the tractor and who knew changing
oil on a 4020 was a science anyway after splitting he tractor
to replace the rear main after about 300 hours and getting
the right dipstick she runs like a Deere

As I stated in an earlier post according to JDparts.com early(< 200999) & late(>201000) model 4020 diesels use the same engine oil pan part # AR63193 OIL PAN (DIESEL) (MARKED R44419 OR R53741) (SUB FOR AR45787) (NLA). Therefore I can't see one model requiring a lot more oil than the other. It appears to me that very many qts over the recommended level would have the rods dipping the oil.

Anybody have access to an Operator's Manual OMR46934 4000, 4020 Tractors (201000-)

Tx Jim,I know there were bigger pans on the late 4020s.They were also on the 4320s.Sorry dont have parts number for you.Some that added turbos used that pan instead of the M&W 20 quart.They were also on 4520s.I actually had one that came off a 70 4020 that we put an M&W pan on.The 12 qt. pans sell good and the 8qt .pans are easy to find .Dont want to get on your bad side and get scolded like(B&D) but I would bet the farm on this one.

I think I don't actually scold b&d but rather disagree or as I intended doing with your statement was to ask for clarification. I guess I should have worded my first question to you better. One problem with b&d is he chooses to change subject rather give PROOF of some his claims.

I've already looked up the part # for an oil pan for early & late 4020. It's the same part # AR63193 which leads up to why I questioned your statement.
If someone can post the part # of the larger capacity JD oil pan(not M&W) for a 4020 that has the oil filter in it please do.
Jim

Tx Jim ,I am wrong on same pan on 4320&4520 as they did not have filter in pan. Im going to look at on my late 4020 and see if there is a visable casting number.I was thinking capacity.A senior moment.Wish you could find me some nice tractors as they seem to be getting harder to find.Actually starting to buy some newer ones but the 4020 side counsels are still my favorite.

I have those senior moments too regular to suit me. I've got my feelers out for any late model 4020's but haven't come up with any.

 

[larryanderson]

Jim ,I crawled under my 4020 and the #864 right in front of drain plug.Usually there are letters also but its very readable.Maybe this will solve this and resolve our question if not maybe we will have to try Mr.Thinker.If I take a picture of an 8 quart and the one on my 4020 it would show the difference as they are deeper.Im not an expert just like to add my 2cents worth if I happen to know which isnt very often.

 

[Anonymous-0]

i think if you check far farther you will find the part # AR63193 is the newer higher cap oil pan used on 69 and up it is the replacement pan for #AR45741 that is the old 8qt pan Deere does this a lot helps keep cost down and makes for better parts replacements

 

[Tx Jim]

Kent
That could be correct. I'm aware that JD sub's later part #s for older parts. I tried unsuccessfully to look up the spec's on the AR63193 oil pan.

 

[Tx Jim]

Larry do you have a OM oR TM for a >SN 201000 4020? Either book should list engine oil capacity.

 

[Ferd]

For what it's worth, I have a 1969 4020 that I bought from Seneca Farms (large corporate farm). Of the 35 tractors they auctioned, 7 of them were 4020s. They were replacing these tractors and had a large shop with an excellent maintenance program. Included with my 4020 were records going back to 1993 listing every bolt, nut, gasket & labor ever done to the tractor. When I got it home I changed the oil (filter in pan) and at 8 quarts (per the manual) it didn't even register on the dipstick. I called the the shop foreman back at Seneca Farms and he said they changed all the pans to larger ones and to try 12 quarts. That brought it to the full mark.

As maintenance conscience as they were (even had a sticker on the dash of the tractor stating to bring in for service and oil change every 100 hours), I can't imagine they would have the wrong dipstick.

 

[4020_1966]

I know that on my 66 I end up with 10 qts to teh full line. If I do 8 plus the 1 for filter I end up near the bottom of the safe. 10 seems to be perfect for it. I dunno.
