2440/2640 coolant filter set-up.

Now that YT is back on line, after last night, here's the pictures that I promissed a couple of you guys. The first 2 will show the filter, mounting pad, and "plumbing" for the kit. It is sold by Deere, for installation on 4000 series tractors. (i.e. 4430, 4440, ect) It is easily adapted to the 2000 seies. The lines start from a screw out plug, that is on the top of the water pump. That line runs to the "inlet" side of the filter, with a petcock in the line. That is to allow you to remove the filter, without loosing any coolant. The outlet line runs to a plug in the block, that allows the filtered coolant to return to the system. There is a petcock in the return line also. The size of the lines restrict the amount of flow out of the water pump. MOST of the coolant continues to travel it's designed path. The Deere part # for the kit is RE63678. It sells for $244.68. (Or at least it did last July) There will be 3 seperate post's with 3 pictures. Here's the first. John

COOLING SYSTEMS' SNEAKY CORROSION
Cooling failing to maintain an antifreeze/additive package is an invitation to cooling system corrosion. But, according to a panel of experts at the fall meeting of the Technology & Maintenance Council, the causes of accelerated corrosion due to electrolysis are not widely understood.

Stray electrical current can travel through cooling systems and wreak havoc, according to Jerry Woerner, manager for service and warranty at Behr America. The problem, Woerner says, is often a case of poor vehicle grounds forcing current to seek alternate ground paths. This can remove metal from cooling system surfaces, causing pitting, corrosion and, ultimately, leakage.

Filters that fit this head are: (WIX#'s)

Chemical type:
24071, 24072, 24073, 24074, 24082, 24088.

Non-chemicial type... filter foreign materials out of coolant, such as stray core sand from block, but DO NOT add conditioner.:
24069, 24070, 24083, 24084.

The different part #'s reflect size of the filter, which depends on system capacity.

This info. is from the WIX Filters Master Catalog. Any automotive supply that sells WIX should be able to access this sizing information.

WIX has a website, WIX.COM, but it may be to consumer oriented to get detailed info. on the coolant filters. (I haven't checked out that info. on the website.) There is contact information on the WIX site for technical assistance for help with specific applications.

WIX-Cool treatment:
16 OZ bottle...24056

The catalog states these products prolong the life of BOTH gasoline or diesel engines.

The conditioner is VERY important. However you can over condition your coolant as well. JD has test strips (basically litmus paper) that shows whether you need to add additional conditioner or not. I check mine twice a year.

The first view shows the "return" side. Note that it doesn't interfer with the block heater lines. This second photo shows the "supply" side. You can see the line as it starts from the water pump. John

This third shot is what can happen when someone doesn't take proper care of a cooling system. This is the cylinder sleeve that "ate" my engine. You can see the rusty holes (looks like a series of dots) along the point where the bottom of the sleeve meets the block. (The sleeve is pictured upside down) I bought this tractor from a doctor that used it on his small horse farm. It had less than 1400 hours when I bought it. I got it CHEAP. No wonder. It lost 2 gallons of coolant, into the crankcase, just loading, and unloading it from the trailer, when I hauled it home. It had never had the cooling system serviced properly. It now has a completely rebuilt engine. Deere doesn't recommend using Coolant treatment if the filter system is used. I hope this answers the questions about how to install the filter kit. Let me know if I can assist anymore. John

Liner pitting, or cavitation-erosion, occurs along the thrust angle of the piston. The liner sits inside the block, and 'rings' like a bell every time that the cylinder fires. This ringing causes intense pressure changes at the cylinder wall, resulting in liner cavitation.

Bubbles form when the piston 'rings' the cylinder during the combustion explosion. These bubbles, imploding against the liner as it collapses them under pressure, gradually, but fatally, attack and bore through the liner.
The coolant additive nitrite, a major component of many SCA packages, protects the liner against the pitting action by forming a monomolecular, ultra thin oxide coat around the liner.
