Your Essential Pre-Ride Checklist: A Step-by-Step Guide
The most important maintenance you can do is the five-minute check you perform before every ride. This is one of the most crucial 2019 can am defender 800 best practices to adopt. Catching a small issue here can save you from a major headache on the trail.
Grab a flashlight and run through this list. Think of it as a conversation with your machine.
- Tires and Wheels: Check the air pressure—refer to the sticker on your machine for the correct PSI. Look for any cuts, punctures, or embedded objects. Give each wheel a quick shake to check for loose lug nuts or bad wheel bearings.
-
Fluids, Fluids, Fluids: This is non-negotiable.
- Engine Oil: Pull the dipstick (located on the passenger side of the engine), wipe it clean, re-insert it fully, and pull it out again. The level should be between the marks.
- Coolant: Check the coolant overflow reservoir level without opening the radiator cap. It should be between the ‘MIN’ and ‘MAX’ lines.
- Brake Fluid: Visually inspect the master cylinder reservoir. If the fluid is low or looks dark and murky, it’s time for a closer look and possibly a flush.
- Controls and Brakes: Hop in the driver’s seat. Test the throttle for smooth operation. Squeeze the brake pedal—it should feel firm, not spongy. A spongy feel is a classic sign of air in the brake lines.
- Lights and Electrical: Turn the key to the ‘ON’ position. Test your headlights (high and low beams), taillights, and brake lights. This is a critical safety check.
- Air Filter Inspection: The air filter is your engine’s lungs. Pop the cover and take a look. If it’s caked with dirt, clean it or replace it. A clogged filter robs your engine of power and efficiency.
Common Problems with the 2019 Can Am Defender 800 (And How to Fix Them)
Here at FatBoysOffroad, we’ve seen our fair share of these machines in the shop. While incredibly reliable, there are a few common problems with 2019 can am defender 800 models that pop up. Knowing what to look for can save you time and money.
Squeaky or Sticking Brakes
The Symptom: You hear a high-pitched squeal when braking, or you feel the brakes dragging slightly after you let off the pedal.
The Cause: This is often caused by dirt, mud, and debris getting packed into the caliper and around the brake pads. The caliper slide pins can also become corroded and fail to move freely.
The Fix: A thorough cleaning is the first step. Use a quality brake cleaner and a stiff brush to scrub the calipers. If the problem persists, you may need to remove the calipers, clean and lubricate the slide pins with high-temp brake grease, and inspect the pads for uneven wear.
CV Boot and Axle Issues
The Symptom: A clicking or popping sound when turning, or you find grease splattered on the inside of your wheels or suspension components.
The Cause: The rubber CV (Constant Velocity) boots protect the axle joints. A tear or puncture from a stick on the trail allows dirt and water in, destroying the joint quickly.
The Fix: Inspect your CV boots regularly. If you find a tear, replace it immediately. Kits are available, but it can be a messy job. If the axle is already clicking, it’s best to replace the entire axle assembly. Don’t delay this repair—a failed axle on the trail is a day-ender.
Shifting Difficulty
The Symptom: The gear selector is hard to move, especially between Park, Reverse, and High.
The Cause: Most often, this is due to a misadjusted shift linkage cable. Over time, the cable can stretch slightly, throwing off the alignment between the shifter and the transmission.
The Fix: You can adjust the linkage. The process usually involves loosening a lock nut on the cable near the transmission and turning the adjuster barrel until the gears engage smoothly. Refer to your service manual for the exact procedure—it’s a simple fix that makes a world of difference.
Smart Upgrades & Performance Mods for Your Defender
Stock is great, but making a machine yours is half the fun. These are some of the most practical and effective 2019 can am defender 800 tips for upgrades that enhance capability without breaking the bank.
Wheels and Tires
This is the single best upgrade you can make. A good set of 8-ply rated, all-terrain, or mud-terrain tires will dramatically improve traction, durability, and puncture resistance. Match them with a quality set of aftermarket wheels for a stronger, more reliable setup.
Skid Plates
The factory protection is minimal. A full set of aluminum or UHMW (Ultra-High Molecular Weight) plastic skid plates is a must-have for anyone tackling rocky or wooded terrain. They protect your frame, engine, and drivetrain components from costly damage.
Lighting
Factory headlights are adequate, but an LED light bar or a set of pod lights will transform your nighttime visibility. This is a huge safety and confidence booster for early morning hunts or late-night trail rides back to camp.
Clutch Kit
If you’ve added larger tires or frequently carry heavy loads, a clutch kit is a wise investment. It recalibrates your CVT system to work more efficiently with the added strain, improving acceleration, reducing belt slip, and extending the life of your drive belt.
Sustainable & Eco-Friendly Best Practices for Your Defender
Being an off-roader means being a steward of the land. A sustainable 2019 can am defender 800 is one that’s not only well-maintained but also operated with respect for the environment.
Proper Fluid Disposal
Never, ever dump used oil, coolant, or brake fluid on the ground or down a drain. Collect all used fluids in a sealed container. Most auto parts stores and local recycling centers will accept them for free. This is a core tenet of being an eco-friendly 2019 can am defender 800 owner.
Wash Smart
Wash your rig on a grassy area or at a designated car wash if possible. This prevents oily residue and mud from running directly into storm drains. Use biodegradable, phosphate-free soaps to minimize environmental impact.
Tread Lightly
The best way to protect the trails is to stay on them. Avoid creating new paths, stay out of muddy areas when possible to prevent rutting, and cross streams only at designated points. Pack out everything you pack in.
The Ultimate 2019 Can Am Defender 800 Care Guide: Key Maintenance Intervals
Following a regular service schedule is the key to longevity. This 2019 can am defender 800 care guide is a general overview—always consult your owner’s manual for specific intervals and procedures.
- After Break-In (First 10 Hours / 200 Miles): This is the most important service. Change the engine oil and filter, and change the transmission and gearcase fluids. Check all bolts for proper torque.
- Every 50 Hours / 600 Miles: Inspect and clean the air filter, check brake pads for wear, inspect CV boots, and lubricate all grease points (zerks) on the suspension and driveline.
- Every 100 Hours / 1,200 Miles: Perform a full service. This includes changing the engine oil and filter, replacing the spark plugs, and inspecting the drive belt for cracks or glazing.
- Annually (Regardless of Hours): Change the brake fluid and coolant. These fluids absorb moisture over time, which can cause corrosion and reduce performance.
