Finding the right dewalt 733 planer parts shouldn't be a massive headache, but when your machine starts making that weird rattling noise or your wood comes out looking like it was chewed by a beaver, you know it's time to dig into the guts of the tool. The DeWalt DW733 has been a staple in small shops for years. It's a literal workhorse, but like any piece of machinery that spins steel at thousands of RPMs, things eventually wear out. Whether you're looking for a simple set of knives or you're trying to track down a specific spring that flew across the garage, knowing what you're looking for makes the whole repair process a lot less stressful.
One of the first things you'll realize when hunting for spares is that the DW733 has different "types." Most often, you'll see Type 1 or Type 2. Before you click "buy" on any dewalt 733 planer parts, double-check the nameplate on your machine. Using a Type 2 belt on a Type 1 machine is a recipe for frustration, and nobody wants to spend their Saturday afternoon repackaging a $15 part for a return.
The Most Common Replacements: Knives and Blades
Let's be real: the knives are the most frequently replaced dewalt 733 planer parts by a long shot. They take all the abuse. You hit one hidden staple or a bit of embedded grit in some reclaimed oak, and suddenly you've got a permanent streak running down every board you plane.
The DW733 uses 12-1/2 inch high-speed steel blades. What's cool about these is that they're usually resharpenable, unlike the disposable ones on some of the newer models. However, there comes a point where you've sharpened them so many times that they just don't have the meat left to perform. When you're shopping for new ones, you'll find plenty of aftermarket options. Some guys swear by the original OEM blades, while others prefer the heat-treated upgrades. Just make sure the mounting holes line up perfectly. If the blades are off by even a hair, the vibration will drive you crazy.
Keeping the Motor Happy: Carbon Brushes
If your planer starts stuttering or you notice some funky blue sparking through the motor vents, it's probably time for new carbon brushes. These are some of the cheapest dewalt 733 planer parts you can buy, but they're also the most overlooked.
Brushes are designed to wear down over time—that's literally their job. If you let them get too low, you risk damaging the armature, which is a much more expensive fix. Replacing them is pretty straightforward. You just pop the brush caps off, slide the old ones out, and click the new ones in. It's one of those "while I'm at it" jobs that saves you a lot of grief down the road. Honestly, it's worth keeping a spare set in your top drawer so you aren't stuck mid-project waiting for a delivery.
Why Your Wood Isn't Moving: Feed Rollers and Belts
There's nothing more annoying than shoving a board into the planer and having it just sit there. If you're pushing the wood through by hand, your feed rollers are either dirty or worn out. Over time, the rubber on these rollers gets slick from sawdust or cracks from age.
Sometimes you can get away with cleaning them with a little rubbing alcohol to restore the "tack," but if the rubber is crumbling, you'll need to browse the dewalt 733 planer parts catalog for a replacement set. While you're in there, take a look at the drive belt. The DW733 uses a ribbed poly-v belt that can stretch or fray. If the belt is slipping, you'll hear the motor spinning fast but the rollers won't be doing much of anything. Replacing the belt is a bit of a literal reach-in-and-fumble job, but it's totally doable for anyone with a basic set of wrenches.
The Bits and Bobs: Screws, Springs, and Knobs
Then there are the "nuisance" parts. You know the ones—the little locking knob that strips out because you tightened it too hard, or the height adjustment handle that gets a bit wobbly. These dewalt 733 planer parts aren't usually "critical" for the motor to turn, but they make the machine a pain to use if they aren't working right.
The blade levelling screws and the hardware for the knife gauge are also prone to getting lost in a pile of wood chips. If you're doing a full teardown to clean out the internal gunk, I highly suggest using a magnetic tray. These small screws are surprisingly specific, and trying to find a replacement at the local hardware store is usually a lost cause because of the thread pitches DeWalt uses.
Dealing with the Dust Hood and Tables
If you've ever used a DW733 without a dust collector, you know it turns your shop into a snow globe in about four seconds. The dust hood is one of those dewalt 733 planer parts that often gets cracked if a board kicks back or if you accidentally bump it while moving the machine. Luckily, the plastic replacements are usually easy to find.
The infeed and outfeed tables also need a little love. If they aren't sitting level, you'll get "snipe"—that annoying deeper cut at the beginning or end of your board. While the tables themselves rarely need replacing unless they're bent, the adjustment bolts and the little plastic bushings can wear out. Keeping these tables dialed in is the difference between a project that looks professional and one that requires an hour of sanding to fix the ends.
Sourcing Your Parts: OEM vs. Aftermarket
When you start digging into the world of dewalt 733 planer parts, you'll see a big price gap between "Genuine DeWalt" and "Unbranded" options. For things like the metal casting or the internal gears, I usually stick with OEM. You want that precision.
However, for things like the drive belt or the knives, aftermarket can be a great way to save a few bucks. Just read the reviews. Some of the cheap belts are made of a rubber that stretches way too fast under heat. If you're running a lot of lumber through, spending the extra five or ten dollars for a high-quality part is almost always worth it. It's better to fix it once and forget about it than to be back inside the machine three months later.
Maintenance to Make Parts Last Longer
The best way to avoid buying dewalt 733 planer parts is to take care of what you already have. It sounds boring, but blowing out the inside of the machine with compressed air after every big session goes a long way. Sawdust loves to get into the chain drive and the threaded rods that move the head up and down.
When that dust mixes with the factory grease, it turns into a thick paste that's basically sandpaper. If the height adjustment feels stiff, don't just force the handle—you'll end up breaking the gears. Instead, clean the threaded rods and apply a little dry lubricant (like PTFE or Boeshield). Dry lube is key because it doesn't attract dust like WD-40 or heavy grease does.
Wrapping Things Up
At the end of the day, the DeWalt 733 is a fantastic machine because it's actually repairable. In a world where so many tools are designed to be thrown away the second something breaks, having a solid supply of dewalt 733 planer parts available means you can keep this thing humming for decades.
Whether you're just swapping out dull blades or doing a full overhaul of the drive system, take your time and make sure everything is aligned. There's a certain satisfaction in taking a machine that's vibrating and screaming and turning it back into a smooth-cutting beast. Just remember to keep that model number handy, grab a set of hex keys, and you'll be back to making sawdust in no time. It's all part of the craft, right? Keep the rollers clean, the knives sharp, and the belt tight, and that 733 will probably outlast half the other tools in your shop.
