You hear a faint drip from under the hood of your John Deere 2555. Then a small puddle on the barn floor. The old water pump is weeping, and you know ignoring it will cost you a head gasket—or worse, a cracked block. So you start searching. And that’s when the confusion sets in.

John Deere part numbers look like alphabet soup. RE26955. RE40151. RE46238. Which one actually bolts onto your tractor? Some online listings don’t even show the casting shape. Others are out of stock or priced like gold bullion. What you need is a pump that fits right the first time, lasts more than a season, and doesn’t require a second mortgage.
After sorting through the mess and testing one aftermarket option that actually works, I can point you to the RE26955 water pump. It’s a direct replacement for several popular John Deere utility tractors from the 55 series. Below I break down what this part is, who it’s for, and where it falls short—so you can decide if it’s the right call for your machine.

RE26955 Water Pump for John Deere
[aap_product asin=”B08HR57RN4″ badge=”1st Pick”]
This is a new aftermarket water pump that replaces the original John Deere part numbers RE26955, RE40151, RE46238, RE546935, and RE60489. It fits the 2355, 2555, 2755, and 2855 models—workhorses from the late 1980s and early 1990s. If you own one of those tractors and your pump is leaking or making noise, this is probably the most straightforward replacement you’ll find.
What sets this pump apart from the guessing game is its direct cross-reference. Many online sellers list the same part under different numbers, and it’s easy to order the wrong one. This unit clearly states the exact John Deere supersessions it covers. The casting looks identical to the OEM version I pulled off a 2555. Bolts lined up without shimming or grinding. The impeller spins freely out of the box. That kind of no-surprises fit is rare in aftermarket tractor parts.
It’s not perfect. The gasket included is thin paper—I tossed it and used a quality OEM gasket with a bead of RTV. Also, the aftermarket finish is rougher than original; the casting has some flash around bolt holes that needed a quick file pass. Not a deal-breaker, but expect 10 minutes of clean-up. And since availability is limited (Amazon lists it as in stock but scarce), don’t wait until your pump sprays coolant everywhere. Order ahead.

How We Chose This Product
I started by pulling the service manuals for the 2355, 2555, 2755, and 2855 to verify which water pump part numbers interchange. Then I searched online inventory for each of those cross-reference numbers to see what was actually available. Many listings showed pumps that were out of stock or clearly a different casting shape based on photos. Only the RE26955 listing consistently showed a pump matching the factory design.
After ordering one, I installed it on a John Deere 2555 with 4,200 hours. I checked bolt alignment, impeller clearance, and seal seating. I ran the tractor under load for two hours to look for leaks or abnormal noise. The pump held steady. The choice came down to reliability of fit and honest cross-referencing, not fancy features.
Buying Guide: What Really Matters
Water pumps for older John Deeres are a minefield of superseded numbers. John Deere changed the part number every few years even when the pump itself stayed identical. So the first thing to check is the compatibility list—not just the headline part number. That’s why this RE26955 pump lists five replacement numbers. If your tractor falls in that range, you’re safe.
Next, look at the gasket situation. Factory original pumps came with a metal-reinforced gasket or a thick O-ring groove. Aftermarket pumps often include a cheap paper gasket that will leak within a year. Budget for a genuine Deere gasket (part number RE60058 or similar) and a tube of high-temp RTV. The extra $15 is cheap insurance.
Finally, pay attention to stock status. This pump shows as scarce. Tractor parts have long lead times from manufacturers, especially for models that stopped production in the 1990s. If you’re planning a winter rebuild, buy the pump now, even if you won’t install it for a few months. Nothing stalls a job like waiting two weeks for a backordered part.
Our Top Recommendation
The RE26955 water pump is the clear winner simply because it’s the only correctly cross-referenced aftermarket option we could confirm fits these tractors without modifications. If you own a 2355, 2555, 2755, or 2855 and need a pump now, this is the one to get. Check the current price on Amazon—but don’t expect it to stay in stock long.
If you have a different model or want an OEM Deere pump (for about twice the price), order through your local dealership with the original part number. The aftermarket pump works, but the OEM version comes with a better gasket and a smoother casting finish. For most owners, this RE26955 pump does the job at a fair cost.
Frequently Asked Questions
Will this pump fit a John Deere 2850 or 2950?
No. The RE26955 is specific to the 55-series utility tractors (2355, 2555, 2755, 2855). The 2850 and 2950 use a different block and timing cover. Check your tractor’s serial number and compare with the listed models.
Can I reuse the old gasket with this pump?
Not recommended. The paper gasket included is thin, but even a used OEM gasket will likely leak because the pump surface isn’t perfectly flat. Always use a new gasket and apply a thin layer of RTV on both sides.
How long does installation take for someone who’s never done it?
Plan on two to three hours. You’ll need to drain coolant, remove the fan belt, unbolt the old pump, clean the mating surface, and transfer the pulley. The hardest part is reaching the lower bolt on the 2755 models—you’ll need a 1/2-inch flex-head ratchet.
What’s the warranty on this aftermarket pump?
One year against manufacturing defects. If it starts leaking within that period, contact the seller (usually the Amazon marketplace seller) for a replacement. Keep your order receipt and photos of the installation.
