How To Check Harley Motor Mounts
Alright, let's talk motor mounts! On your Harley, those trusty little (or not so little) bits are what keep that awesome engine bolted to the frame. They're kind of like the unsung heroes of your ride. But, just like any part, they can wear out. And trust me, you don't want them failing on you mid-ride. Imagine that rumble turning into a rattle... not cool.
So, how do you check 'em? It's easier than parallel parking a '67 Panhead, I promise!
Visual Inspection: The Eyeball Test
First things first: give 'em a good once-over with your peepers. We're talking a serious stare-down here. Look for anything that screams, "I'm broken!" This means:
Must Read
- Cracks: Obvious, right? Big ol' splits in the rubber or polyurethane. If you see cracks, it's like spotting a wrinkle on a celebrity… not a good sign.
- Tears: Rips and tears indicate some serious stress. It’s like your mount is crying out for help (or maybe just a replacement).
- Dry Rot: This looks like cracking and crumbling. Think of it as the Mount equivalent of a bad sunburn.
- Oil Soaking: If they look excessively oily, it means the mount material is breaking down. Oil and rubber usually don't mix well, unless you're talking tires, of course!
- Deformation: Is it all squished and misshapen? It should have a fairly uniform shape. Think of it like a perfectly formed… marshmallow! Unless it's misshapen then it's a botched marshmallow.
Pro-tip: Use a flashlight to get into those hard-to-see spots. Sometimes, the damage is hiding. It's like playing detective, but with motorcycle parts!
The Rock and Roll Test: Checking for Play
Okay, this is where things get a little more hands-on. We want to see how much the engine moves relative to the frame. And no, I don't mean starting it up and watching it vibrate, that’s normal!
Here’s the drill:
- Stabilize the bike: Make sure your bike is secure, either on a jack or a lift. Safety first, always! We don't want any accidental motorcycle naps.
- Grab the engine: Find a good, solid place to grip the engine. Preferably somewhere that won't burn you. (Ask me how I know...).
- Rock it: Gently try to rock the engine back and forth, side to side. You're feeling for excessive movement. A little movement is normal, but if the engine feels like it's doing the tango with the frame, you've got a problem.
Important: Pay close attention to the motor mount areas while you're rocking. If you see a mount flexing excessively, or if you hear clunking or squeaking, that's a sign it's time for a replacement.
The Bolt Check: Tighten Up!
While you're down there, give the motor mount bolts a check to make sure they're properly torqued. Use a torque wrench and consult your service manual for the correct specifications. Loose bolts can cause all sorts of problems, including premature wear on the mounts themselves. Plus, a loose bolt can cause vibration that no Harley rider likes! (Except maybe the guy who invented the vibrating seat... but I digress.)
When in Doubt, Replace!
Look, if you're even slightly unsure about the condition of your motor mounts, it's always best to replace them. They're relatively inexpensive, and the peace of mind is worth it. Plus, riding with worn-out motor mounts can lead to all sorts of other problems down the road, including frame damage. Think of it as preventative maintenance. Like flossing…but for your Harley!
Checking your motor mounts is a crucial part of keeping your Harley happy and healthy. And a happy Harley means a happy rider! So, get out there, give those mounts a once-over, and enjoy the ride! You’ve got this!
