Ingersoll Case Garden Tractors

Just wondering is it possible to get new Hydraulic Hydro pump for 448 Ingersoll Case Garden tractor? If so what would the cost be about? Thanks
 
That referenced kit is a good idea. The 'u' hose is a common leak point and changing it with the pump is a smart move.

You may be able to beat the pricing by purchasing the pump from another source, Google can help using the part number in that ad.

Or, used ones are available, I might have one if you're interested in that approach.

IMO, there is some confusing information in the posts given so far. I will attempt to clear some things up.

Almost ALL the pumps used in the Case and Ingersoll garden tractors are of the Double A or AA size.

Case used Double AA pumps from Parker-Hannifin. The Single A or "A" size of pumps were made by Cessna, Wooster and a couple other brands but these are mainly found in the old 100 Series Case tractors from the 60's and the Colt tractors from the same era. Some of the 600 Series loader and loader/backhoe models also use the A style pump as did a few of the very early 200/400 Series Case tractors.

IMO, trying to rebuild one of these "throw-away" pumps is pointless. None of the Case or Colt tractors came with an oil filter and far too many owners never changed the hydraulic oil because "it did not look dirty". Therefore, all of the metal filings and other contaminants were free to cruise around the hydraulic system and gouge aluminum and steel parts whenever the tractor was running. The smart money chooses to drain the system with the old pump in place and then refill it with Varsol or diesel fuel before running the engine again. After 10 minutes run-time, you can drain out the Varsol or diesel fuel. If it looks dirty, then repeat and see if it clears up.

Find 3 quarts of any brand of cheap motor of any viscosity and run the tractor for ten minutes with that in the system. This is done to absorb any remaining diesel or Varsol . Upon draining this out, the time has come to install a BRAND NEW pump and suction hose using the proper clamps. Examine the pump coupling for damage and replace the rubber spider no matter how good you think it looks. These items get hard and brittle with age and reach a point where they quietly disintegrate behind your back and then destroy the pump coupling halves.

Pay special attention when assembling the coupling to make sure you leave around 60 thou of space between the spider and the coupling on one side. If you do not do this, the new spider will be destroyed because everything will expand when operating temp is reached and starts squeezing the life out of the new spider. Use a thread locker on the set screws in the coupling halves and make sure that the keys are positioned properly in the key-ways and that the coupling half's are properly positioned on their respective shafts.

Double check the hose clamps to make sure they are tight. Refill the system with 15W40 Shell Rotella oil or the equivalent. If you live in a warmer climate, then use 20W50. Make sure your oil cooler is 100 percent clean and without damage. Check your cooling fan for broken or damaged blades. These get brittle with age and should be replaced from time to time.

NEW OR USED?

Only a New Pump will give you the best performance out of your tractor and any of the hydraulic attachments you may own.


Your tractor works best with a hydraulic flow rate of about 10 gallons per minute at 3600 RPM. A Used Pump would be a question mark unless it was tested on a FLOW BENCH to see how well it was still performing. All hydraulic pumps begin to wear, the second they are put into operation. How long they last is highly dependant upon how well the system is maintained. If money is tight, then a used pump from Ken Combs is a viable option because he does not knowingly sell junk and he stands behind what he sells within reason.

The pump kit from Casegardentractorparts.com is well worth considering. Bob Myer has been in the business for decades and is highly reputable. I have no qualms about endorsing either of these gentlemen. Good luck with your repair.
 
Kevin,
If your using "Modern View" be sure to look at this thread in "Classic View".
There are some posts in this thread that only show up in Classic and not Modern.

It is quite confusing as is some info posted here in Modern View.
I do not know what is "confusing info" as the claimant did not elaborate on what is confusing.
 
Never tried to get a hyd pump for a lawn tractor but have saved big bucks buying pumps for trencher and skid loaders from local hyd shop.Probably half the $$$ of OEM.
