just checked my JD 4300 rockshaft filter and there was a hole blown thru it (55 hrs). Looks like someone drove a scrrewdriver through the screen. I called my local JD dealer and they had never heard of this rockshaft filter and they could not find it on the computer. The Service Manager had no idea what I was talking about. I called John Deere's toll free number and talked to someone who gave me a part number after about 1/2 hour of looking. He said it was LVA12302. Could someone verify this. He also said the new 10 series tractors have been re-designed with a new filter assembly. I ordered this new filter and it is about twice as long and will not work--maybe I need some more pipes and or fittings. I have attached a picture of the torn screen. Does anyone know of retrofits for the 4300 tractor?

Thanks,

The screen you are looking at is normal; most have a small hole as shown in your picture. Problems arise when debris accumulates on the screen and impedes oil flowl, when this happens pressure will blow the screen into the position control valve. At this point, the control valve must be replaced, you can attempt to clean it, but in most cases replacement is called for.
You might talk to your dealer and describe the situation outlined in the new service manual (on line version if you do not already have the revision). He may, may not agree to provide you with the updated filter/tube assembly. If not, you can order the parts if so desired, you will need the following part #:

LVA11765 Oil Line (Left Side line) $15.93

LVA11289 Filter (This is the complete filter assembly, you will not need any additional parts) $27.34
Note: May also be under part # LVA12302 (Check with you dealer)

LVA11210 Oil Line (Right Side line) $21.00

T77932 O Rings (Pkg) $4.80

To install, follow instruction in owner’s manual. Be sure to replace O-rings. Remove fitting from position control valve, you may elect to replace the fitting with part #LVA11299, same fitting as installed without filter screen, however this is not necessary, just take a small drift punch and drive the screen out. This is not difficult. Re-assemble and check for leaks.

Hope this has been of some help.

Thanks for this great info with part numbers. I would assume this newly designed remote mounted is better than the inlet filter. I have heard of the inlet screen being blown into the rockshaft with the old filter. Is this possible with the new filter? You say the new filter is LVA11289. What parts does the LVA11289 include, if any , over the LVA12302? You also say to follow the owner's manual for installation. My manual does not show this new filter and the on-line manual shows my filter in the inlet to the rockshaft. Where can I get instructions for this new remote mounted filter?

Any opinions on the old vs new remote mounted cannister filter?

Thanks for all the help.

Checked the part number again, the ones in stock reflect the latter part number, i.e., LVA12302. The long line, attaches to the right hand side and routes around to the rear of the tractor, terminating under the top 3-point hitch link bracket, between the top link housing and PTO shield, then the new filter assembly, and the left hand line, the shorter of the two. Both lines are attached to existing fittings as described in my original post.
The new filter assembly is approximately four inches long, 1 ¼ inch in diameter, both ends have male fittings with O rings, the outlet end (marked out on fitting)(outlet end will face to the left side of the tractor when installed) is a dual male fitting with a hex head machined into the fitting allowing the housing to be dissembled for filter element change. If you ever have one apart there are two springs and a filter inside, the filter is like a step down cone, the large spring fits over the step down and is inserted first, followed by the filter, and the smaller diameter spring. However, when you purchase the filter, it comes assembled ready for installation.
As you will have to talk with you dealer to obtain the parts, have them look in the 4000ten series parts catalog, 4310 Compact Utility Tractor, Section 70, Page 39, under the name “Hydraulic Lines (Rockshaft)”, they will see a parts breakdown “MP27279. “ They should be able to print this out for you. It will show what I’m trying to describe. It’s really not difficult, did one Saturday. Also if you dealer still has any of the late production 4200, 4300, or 4400 tractors or the Ten Series of these, you can look at the rear and see the new filter and how it is installed.
As for opinion on new vs. old, maybe it’s just me, but everything seems to work better. Even more important is the peace of mine knowing the new one will not fail and cause downtime.

Sorry, miss read the last portions of your post, thought you were asking about the new inline filter vs. the old screen.
As for an opinion on the old vs. new remote mounted canister filter, can’t really say at this time. Don’t know of any problems with the old style with the exception of changing the Hydro filter to a larger canister to gain more volume.

Is this problem unique to hydro. models? Just picked up a leftover 2000 4300 syncrev. and wonder if this is also a concern with gear transmissions. Also when you switch over to the new filter design what is the filter replacement frequency?

Where is this filter located on the tractor?

The filter is basically a screen located in a brass fitting under the seat. Check out the information found in the online manual link below. It filters the hydraulic fluid prior to going into control valve. Problems arise if hydraulic fluid pressure causes screen to dislodge. In later model 4300's and 4310's the filter is a canister type located just above PTO guard.

Is this problem unique to hydro. models? NO!! The problem deals with the hydraulic system (screen specifically)and has no relationship to transmission choice.
As I have stated in a reply to this question back in April, once you see the replacement parts, it will become clear as to replacement loction. Addressing the filter change issue, will have to check the book on that one.

Unregistered,

Have no problem with understanding the location of the new layout. My dealer got me the new oil lines and fitting allready but didn't provide the new filter canister/o-rings yet. I understand that the screen was used in all transmission types but reasoned that the hydro. units may have more particulate matter thus having more of a tendancy of blowing out the screen. Searched all posters with this problem and found all had hydro. units. Are you aware of any syncrev. transmissions that had the screen dislodge? My unit is this type with 21 hours. Waiting for filter and not sure I should use until I do this upgrade.

Thanks,
Al
