Finding the right meyers e47 parts can be the difference between finishing your driveway in twenty minutes or spending four hours shivering in the garage with a frozen wrench. If you've been around the snow removal game for a while, you know the Meyer E-47 pump is a total workhorse. It's been around forever, and for good reason—it's simple, it's durable, and it's relatively easy to fix yourself if you know what you're looking at. But, like any piece of hydraulic machinery that spends its life submerged in salt, slush, and freezing temperatures, things are going to wear out.
When your plow starts acting up in the middle of a Nor'easter, you don't have time to second-guess which O-ring or solenoid you need. You just want the thing to lift, lower, and angle so you can get back into the warm cab. Let's break down the components that usually fail and what you should keep on hand.
The Heart of the System: The E-47 Motor
The motor is usually the first thing people suspect when the plow won't move. You flip the switch, and nothing. No hum, no click, just silence. Before you go ripping the whole unit apart, it's worth checking the motor itself. These motors are pretty resilient, but they hate moisture. Over time, the seals can fail, letting a little bit of salty brine inside, which eventually eats the brushes or rusts the armature.
If you're looking at replacement meyers e47 parts, you'll find that the motors come in a couple of different styles. Some have a single terminal, while others are a bit more modern. Honestly, if your motor is dragging or sounds like a blender full of gravel, it's probably time to swap it out. It's a lot easier than trying to rebuild the internal brushes while your fingers are numb.
The "Big Three" Valves
This is where most of the magic (and the headaches) happens. The E-47 uses three specific solenoid valves—usually referred to as the A, B, and C valves. If your plow is doing something weird, like lifting but not lowering, or angling one way but not the other, one of these is likely the culprit.
The A Valve (The Lowering Valve)
The A valve is responsible for letting the plow down. If your plow stays stuck in the air, or if it drifts down slowly while you're driving, the A valve is the first place to look. Sometimes it's just a bit of grit stuck in the seat, but often the internal needle gets bent or the coil burns out. It's one of those meyers e47 parts you should always have a spare of in the glove box.
The B Valve (The Lift Valve)
If the motor is spinning but the plow won't get off the ground, the B valve is usually the one to blame. It's what directs the pressurized fluid into the lift ram. These see a lot of pressure, so the seals can get chewed up over a few seasons. If you hear the motor straining but the blade stays put, check the B valve coil first to see if it's even getting magnetized.
The C Valve (The Angling Valve)
This one handles the side-to-side movement. If your plow is "floppy" or won't angle to the right, the C valve is likely stuck. Much like the others, these can get clogged with the "milkshake" (that gross mix of hydraulic fluid and water) that builds up inside old pumps.
Seal Kits and the Infamous "Milkshake"
If you look at your pump and it looks like it's sweating oil, or if the fluid inside looks like a strawberry milkshake, you're overdue for a seal kit. Water finds its way into these units through the top wiper seal or the reservoir base over time. Once that water mixes with the oil, it loses its lubricating properties and starts to freeze in the small passages.
A full seal kit is one of the most affordable meyers e47 parts sets you can buy, but it requires some patience to install. You'll be replacing the O-rings on the base, the nylon spacers, and the main wiper seal on the lift ram. It's a messy job, but doing it once every couple of years will save you from a catastrophic failure when it's ten below zero. Pro tip: Use a pick tool to get the old O-rings out, but be careful not to scratch the aluminum housing, or you'll have a permanent leak.
Solenoids and Wiring: The Electrical Gremlins
Sometimes the mechanical parts are fine, but the electrical signal never reaches them. The starter solenoid (that little metal box usually mounted on the firewall or near the battery) takes a lot of abuse. It's basically a heavy-duty relay that sends the big surge of power to the pump motor. If you hear a "click-click-click" but the motor doesn't turn, your solenoid is likely fried.
Don't forget the ground wires, either. These plows use the truck's frame for grounding, and salt loves to eat through those connections. If you're replacing meyers e47 parts and the thing still won't work, take a wire brush to your ground points. It's a free fix that solves about 40% of all plow problems.
The Reservoir and Base
The main body of the E-47 consists of a metal reservoir and a heavy cast base. If you've hit something hard—and let's be honest, we all have—you might find cracks in the base. Also, the mounting lugs where the pump attaches to the lift frame can wear out or snap.
Inside the reservoir, there's a small filter screen. This is a tiny part that a lot of people overlook. If that screen gets plugged with metal shavings or old gunk, the pump will starve for oil. It'll sound high-pitched and won't have any power. Whenever you drain the fluid to change meyers e47 parts, make sure you pull that screen out and clean it with some brake cleaner.
Keeping Your Parts Happy
The best way to avoid buying a whole new catalog of parts is simple maintenance. At the end of every season, drain the fluid. Don't just top it off; get the old stuff out. Use a high-quality blue hydraulic fluid designed for low temperatures. Some guys try to use ATF (Automatic Transmission Fluid), and while it works in a pinch, it can be a bit harsh on the older seals.
When you're storing the plow for the summer, coat the chrome lift ram and the angling cylinders in a thin layer of grease. This prevents pitting and rust. If the ram gets rusty, it'll act like sandpaper on your new seals the first time you use it next winter, and you'll be right back to square one.
Why Quality Matters
You'll see a lot of "off-brand" meyers e47 parts online these days for dirt cheap. While some of them are okay, you have to ask yourself if saving ten bucks is worth the risk of the part failing when there's a foot of snow in the forecast. Genuine or high-quality aftermarket parts tend to have better tolerances and better rubber compounds in the seals.
The E-47 is a classic for a reason. It's built like a tank, and as long as you keep the fluid clean and the electrical connections tight, it'll probably outlast the truck it's mounted on. Just make sure you have a small kit of the essentials—an A valve, a solenoid, and a quart of fluid—tucked under your seat. It's the best insurance policy you can have against a cold night of shoveling by hand.
Anyway, if you're staring at a pump that's leaking or acting sluggish, don't sweat it too much. These things were designed to be rebuilt. Get yourself a good set of wrenches, a clean workspace, and the right meyers e47 parts, and you'll have that blade dropping and lifting like new in no time. Winter isn't going anywhere, so you might as well be ready for it.
