The Arctic Cat Alterra 700 is a hard-working 695cc utility quad built around the same H1 single-cylinder engine family you’ll find under the hood of the brand’s Prowler 700 side-by-sides. On paper it is a strong trail and work machine, but owners on the Arctic Cat boards are quick to name two recurring headaches: an intermittent P0336 crankshaft position sensor code that keeps coming back, and a CVT belt that slips under load when the machine is worked hard or fitted with a big-tire clutch kit. In this guide I walk through the problems that actually show up in real owner threads, plus the causes and fixes that hold up in practice, then close with a used-buying checklist and the maintenance habits that keep the 695cc single alive.
P0336: the crankshaft position sensor code that keeps returning
The single most-reported engine complaint on the Alterra 700 is fault code P0336, which points at the crankshaft position sensor. One 2017 Alterra 700 XT owner documented the full cycle in the “New 2016 Arctic Cat Alterra 700 issues” thread: the machine went back to the dealer on a P0336 code, came home after an ECU update, then threw the same code again after a 200-mile ride and a bout of belt slip and a rear-end oil leak. On the third visit the dealer kept insisting it was loose battery connections, then a different story about revving in park. The owner said he never revved it in park. He also found the tell: if he started the quad and let it idle for about three minutes, the engine would stumble and the code would pop. Start it and ride, no code.
That pattern is a classic intermittent sensor or wiring signal, not a mechanical failure. A sensor that reads dirty under the slight heat-soak of a three-minute idle, or a harness that loses continuity when the bike sits and vibrates, produces exactly this on-and-off behavior. If your Alterra 700 tripped P0336, inspect the crank sensor connector and the pins, then verify the harness routing for chafing before you pay anyone to replace parts. Clean the connector, confirm the pickup gap, then check for damage where the harness crosses the frame. A steady, repeatable P0336 can also be a bad crank sensor or its tone ring, but the intermittent stumble-after-idle symptom points more often to a connection.
Because this code kept recurring through multiple dealer visits with no lasting fix in the thread, treat a new-to-you Alterra 700 that throws P0336 as a bargaining point. You can read how the 700’s close sibling, the Arctic Cat Prowler 700 XTX, handles its own set of engine and drivetrain gremlins in our separate breakdown.
CVT belt slip under load in mud and four-wheel drive
The Alterra 700’s belt-driven CVT is the same basic package Arctic Cat has used across the 700 family, and under hard use owners report the belt giving way. The clearest account is the “Belt slipping 2016 700 alterra” thread: an owner running 28-inch Silverback tires and an EPI mudder kit said the bike felt sluggish and the belt would slip under load in mud and in 4WD, and felt gutless riding two-up.
Before you blame the belt, work through the clutch. The same owner took the assembly apart and freed the primary rollers that were sticking, then confirmed with Arctic Cat and other owners that the OEM stick belt is the better choice over aftermarket options. He also discovered the EPI kit had shipped him the wrong secondary spring, built for a utility clutch rather than a mud clutch. Swapping to the correct spring helped, but slip did not fully disappear until a shop looked at machining and setup. So the sequence is: clean the clutch faces, free any sticking rollers, verify the secondary spring matches your clutch style and riding, then judge the belt. A clean, correctly-tuned clutch rarely slips a new OEM belt.
The takeaway for anyone serious about big tires and mud is that the stock drivetrain needs matching clutch work, and parts can arrive mislabeled, so confirm part numbers rather than trusting the kit. This is the same CVT architecture that gives the CFMoto CForce 600 its power delivery, and that machine has its own clutch quirks worth knowing before you buy.
Clutch tuning after big tires and a lift kit
Alterra 700 owners who lift the quad and mount oversized tires quickly discover that the stock clutch was tuned for the factory 25-inch rubber. In a companion thread, the same owner running the EPI mudder package reported the kit engaged at around 2,500 rpm with 14-gram primary weights, a white secondary spring, plus stiffer wet-clutch springs. He never measured the stock engagement before the mod and the dealer could not tell him, which left him tuning blind. The lesson: log your RPM at engagement and your full-throttle shift before you change anything, so you have a baseline.
When a big-tire machine bogs or slips, check three things first. Rollers that stick in the primary are a known cause of inconsistent shift and are cheap to free and clean. The secondary spring that does not match your clutch type changes how early the secondary opens. And a shim in the primary changes the starting ratio, which some owners add to keep a heavy tire turning from a stop. None of this needs a new clutch; it needs matched parts and a clean assembly. Keep your own numbers so the next tune is an adjustment, not a guess.
Oil in the belt housing and rear-end leaks
Threads across the 700 family mention oil finding its way where it should not, and the Alterra is no exception. The owner with the P0336 saga also reported a rear-end oil leak and belt slipping within the first 200 miles of a brand-new machine. On these belt-driven Cold War-era layouts, oil in the belt housing usually comes from a seal or a one-way bearing behind the clutch shaft, with the belt often slipping soon after. If you open the cover and find oil, you do not get to just clean it and move on; you have to chase the entry point or the slip comes back.
On the 700 side-by-sides, owners have replaced the one-way bearing and the clutch-shaft o-ring only to see the leak persist around the outer seal, so do not be surprised if it takes more than one seal. On the Alterra, check the clutch-shaft seal and the case vent first, then confirm the CVT breather is not routed so it siphons. The same engine and drivetrain family is covered in more depth in our Prowler 700 XTX problem guide, including the belt-housing leak reports.
Specs that matter: what the official sheet actually says
Arctic Cat’s own Alterra 700 spec page lists a 695cc SOHC, 4-stroke, 4-valve engine with EFI, a 102 x 85 mm bore and stroke, liquid cooling with a fan, plus a 28-amp alternator. It is a single, not a twin, driving through an automatic CVT with engine braking, Hi/Lo range, neutral, reverse and park, with 2/4WD plus an electronic front differential lock. Suspension is a double A-arm at both ends with 10 inches of travel and 11 inches of ground clearance, wrapped in 25×8-12 front and 25×10-12 rear Duro Kaden tires.
Two things are worth pointing out because they contradict what shows up in older write-ups. The official dry weight is 734 lb rather than the 699 lb some reprints claim, and the wheelbase is 52 inches rather than 50.5. Fuel capacity is 6 gallons. The official page does not publish horsepower or a top speed, so any exact figure you see online is an estimate, not a factory number; call this engine a solid mid-size work single rather than quoting a power guess.
Ask the seller: a checklist for a used Alterra 700
When you are looking at a used Alterra 700, the P0336 story above is your first red flag. Ask whether the current owner has ever seen that code, because the intermittent version is easy to hide and just as easy to ignore. Pull the battery connections and confirm the charging system holds a decent voltage; a healthy alternator and a clean battery are cheap insurance, and a battery maintainer keeps the quad ready when it sits between rides.
Check the belt housing for oil residue and ask when the belt was last changed and with what belt. Owners consistently prefer the OEM stick belt, so a bike running an obvious aftermarket belt deserves a closer look at the clutch faces and the rollers. Look for evidence of big tires or a lift that was removed before sale, because a returned-to-stock quad may still carry incorrect clutch parts from its modified life. Test the 4WD and the front differential lock on the spot, and confirm Hi/Lo both engage. Finally, a clean title and service records matter more here than a shiny fender, since the machine’s history drives most of its future problems.
For perspective on what other mid-size quads do right and wrong, our Yamaha Grizzly 700 guide and Can-Am Outlander 570 guide cover two popular neighbors of the Alterra.
Maintenance that keeps the 695cc single happy
Most Alterra 700 problems trace back to neglected basics. Keep the CVT cover clean and open it for an inspection when you do the major services, then wipe the clutch faces and free any rollers that feel sticky. Use a fresh OEM-style stick belt when it is due, and check the secondary spring and its orientation each time the cover is off. An improperly seated secondary shoe can open the clutch almost instantly and cause the exact barking and slip owners describe, so never assume it is right after reassembly.
The engine is liquid-cooled, so flush the coolant on the schedule in your manual rather than clinging to the classic “when it looks brown” habit. The 28-amp alternator covers a winch and accessories easily, but a quality CVT belt from a known source still beats the cheapest option. The EBS engine braking means the belt pulls real load on descents, so spend on a belt built for that duty instead of the lightest one on the shelf.
Keep grounds and the main harness clean and well-routed, because the intermittent sensor symptoms on this platform often come from a poor connection rather than a failed part. If you are shopping for replacement parts, use the Grizzly and Outlander builds above as a reference for how other owners approach maintenance on comparable utility quads.
Bottom line. The Arctic Cat Alterra 700 is a capable, comfortable utility quad whose 695cc single and belt-driven CVT are reliable enough on the whole, but two issues show up again and again in owner threads: the recurring P0336 crankshaft sensor code and CVT belt slip under load. Neither is catastrophic if you catch it early. Keep the clutch clean and correctly tuned, verify sensor connections before replacing parts, and inspect the belt housing for oil when you buy or service one. Do that and a well-kept Alterra 700 will earn its keep for years.
