Hardline Products® Inductive Hour Meter

Description

The Ultimate Precision Maintenance Tool for Gas-Powered Engines

Take the guesswork out of engine maintenance with the Hardline Products® Inductive Hour Meter, the industry standard for tracking service intervals on gasoline engines. Designed for power-sports enthusiasts and equipment managers alike, this surface-mounted meter provides the accurate data necessary to maximize the lifespan and performance of your machinery.

Unlike mechanical meters that rely on vibration or internal gearing, this solid-state digital meter utilizes advanced inductive technology to track engine runtime with absolute precision. Whether you are managing high-performance 2-stroke or 4-stroke engines, this device is the key to a successful preventative maintenance program—ensuring oil changes, valve adjustments, and spark plug replacements happen exactly when they should.

Key Features & Benefits

• Universal Compatibility: Engineered to work seamlessly with any gasoline engine, regardless of cylinder count or displacement. It is fully compatible with both 2-stroke and 4-stroke engines, including modern fuel-injected models equipped with “pencil” coil ignition systems and older generation ignitions.
• Advanced Trip Tracking (TM1 & TM2): Features two independent, resettable trip meter modes (TM1 & TM2). Much like the trip odometer in a car, these allow users to track specific intervals (e.g., time since last oil change or duration of a specific ride) without affecting the total accumulated engine hours.
• Effortless “Peel & Stick” Installation: No complex wiring, grounding, or external power sources are required. The patented one-wire inductive hook-up simply wraps around the spark plug wire. The unit mounts securely to any flat surface using the included industrial-strength adhesive.
• Extreme Durability: Built to withstand the harshest environments, the unit is 100% epoxy encapsulated, making it fully waterproof and shock-resistant. With an IP-68 rating, it is impervious to dust, dirt, and water immersion, making it ideal for marine, off-road, and industrial applications.
• Always-On Digital Display: The modern LCD screen is readable whether the engine is running or turned off, allowing for easy logging of hours in the garage or shop.
• Maintenance Log Book Included: Every unit comes with a hard-copy log book, facilitating organized record-keeping of all service performed based on the meter’s readings.

Frequently Asked Questions

Installation & Compatibility

Q: How do I mount my hour meter? A: Our hour meters include two-sided tape and two serrated screws for mounting. You can use the tape and/or the screws. The tape alone is enough to hold the meter in most applications. You can mount your hour meter anywhere except on exhaust manifolds or mufflers. High engine heat temperature will not affect the meter. Vibration and water will not harm your meter either. Choose a location that is easy to read but out of the way from moving parts or an area where meter could be struck or scraped off.

Q: Why is my screen always on? is this killing the battery? A: Our screens always stay “Lit” so you can glance at the meter anytime to read the hours. This does not affect the 10 year battery life of your meter.

Q: How do you install an inductive hour meter? A: Installation is simple with our patented one-wire inductive pickup. Just wrap the wire around your spark plug wire—no cutting, splicing, or hard-wiring required. It works seamlessly on any 1 or 2-cylinder gas engine.

Q: How do I know my meter is working? A: When installed correctly the “hour-glass” icon on the left hand side of the meter will flash when the engine is running. Remember it will take 6 minutes of running before you see “.1” on the screen for total hours.

Features & Operation

Q: What is an inductive hour meter? A: An inductive hour meter tracks engine runtime and RPMs by sensing electrical pulses from the spark plug. Our meter automatically switches between a tachometer when the engine is running and an hour meter when off.

Q: What is TM1 and TM2 at the top right side of the screen? A: If you bought an Hardline Products standard hour meter (p/n HR-8063-2 or HR-8061-2, HR-8062-2,) and you see TM1 or TM2 when you push the button, you have an hour meter that includes two trip meters. Just like the trip meter on your car you can reset the trip meters when ever you desire or leave them to accumulate. Use the TM1 and TM2 function for air filter changes or top end rebuilds. Total hours accumulated will not be reset. To reset hold button down to scroll to TM1 or TM2. Release button and then hold down until trip hours reset to 0. Do this for each “TM1” and “TM2” modes.

Durability & Lifespan

Q: Is the Hardline hour meter waterproof? A: Yes, it features an IP-68 waterproof rating. The meter is 100% epoxy-encapsulated, making it completely resistant to complete water submersion, heavy dust, shock, and extreme vibration.

Q: Does the hour meter have a replaceable battery? A: No, the unit features a sealed, internal lithium battery designed to last for 10 years. This completely sealed design ensures maximum durability and maintains the IP-68 waterproof rating throughout the meter’s lifespan.

Q: Is the hour meter I get been on the shelve for 2 years and now I only have eight years of life left? A: No, your hour meter is typically 2-3 weeks old, that’s it! We are the largest manufacture of hour meters and we can’t make them fast enough!

Q: How do I get a longer wire on my hour meter? A: Our wired hour meters include a 12″- 14″ pick-up wire. If you need a longer wire we offer 5, 10 and 15 foot lengths on our website. https://www.hardlineproducts.com/product/wire-for-hour-meters/ you can also use 18 or 20 gauge automotive wire from the auto parts store. Use one continuous piece with no splices or connections. We suggest testing the length of wire before you plumb it. We have had success up to 14 feet long pick-up wire length.

Q: I purchased your hour meter for my new four stroke and the coil must be built into the plug cap as it doesn’t have a spark plug wire. Is there another way to connect it? A: The newer four-strokes engines and motorcycles (YZF, CRF, KXF, etc..) have the coil mounted right on top of the spark plug, thus there is no coil wire running down to the plug like the old days! No problem, our hour meter will still work. Wrap the wire around the circumference of the boot or the round epoxy case that covers the spark plug. A few revolutions around the boot or coil head will suffice. Call us at 888-413-8315 and we will try to help.

Q: I have a pen-stick coil and wrapping your pick-up wire around the outside of the coil but the hour meter will still not record time A: Sometimes the coils are very insulated and you have to remove the coil and push our pick-up wire down into the hole where the spark plug is, then reinstall the coil and test again.

Motorcross Action Magazine MXperts Column: “Dear MXxperts what can I do to catch problems before they ruin my day and my bank account?” -Hour Meter. It’s not a matter of if your four-stroke will blow but when. With proper service, your four-stroke can easily last three years—or 100 hours, whichever comes first. The key is regular maintenance. Consistently pull the top end down to measure what your rate of wear is. Personalize a maintenance baseline based on your own rate of wear.
