OLIFANT Starter Drive Bendix for Polaris ATVs 17-Tooth CCW (39mm) — Direct-Fit Replacement, OEM-Equivalent

OLIFANT Starter Drive Bendix is a direct-fit 17-tooth, counterclockwise starter drive engineered to replace worn starter Bendix units on a wide range of Polaris ATVs and Rangers.

This replacement starter drive is made to meet OE fitment for many Polaris models—including Sportsman, Scrambler, Big Boss, Magnum, Xplorer and Trail Boss—covering years from the mid-1980s through 2014. It restores reliable engagement between the starter motor and engine flywheel when the original Bendix wears out, reducing starter slip, grinding, and intermittent starts. The part numbers that correspond to this unit include OE references 3083647, 3085394, 3087030, 3089255, 3090034 and aftermarket codes SM1329850 and SMU5003.

Which Polaris models will this starter drive fit?

This OLIFANT Bendix is compatible with many Polaris ATVs and utility machines. It’s intended as a replacement for models that originally used a 17-tooth (39 mm OD), counterclockwise starter drive. Double-check your OEM part number or tooth count before ordering to ensure proper fit.

• Sportsman: 335, 400, 450, 500 (years up to 2014)
• Scrambler: 400, 500, 400L — 2x4 & 4x4 (1984–2012)
• Big Boss & Magnum series: multiple 250–500 models (1989–2006)
• Xplorer & Trail Boss line: common 250–500 models and variants

How does this replacement Bendix improve starter performance?

Replacing a worn Bendix restores proper mechanical engagement between the starter pinion and the engine ring gear. That eliminates common starter issues such as slipping or grinding and helps the starter motor deliver consistent torque to crank the engine.

• Correct 17-tooth pitch and 39 mm outer diameter for precise meshing
• Counterclockwise rotation matched to specified Polaris starters
• OEM-equivalent part numbers for straightforward swap-in replacement

What should I check before installing this starter drive?

Verify the tooth count, overall diameter, and rotation direction against your old Bendix or factory service manual. Also inspect the starter housing and flywheel teeth for damage—replacing the Bendix won’t help if mating gears are excessively worn.

• Confirm 17-tooth, 39 mm OD, CCW specification on the existing unit
• Compare OE numbers: 3083647, 3085394, 3087030, 3089255, 3090034
• Check starter shaft fit and clean mating surfaces before installation

How do I install this Bendix and what tools are needed?

Installation typically requires removing the starter motor from the ATV, disassembling the starter to access the Bendix, and swapping the old drive for the new unit. Basic hand tools and a torque wrench are usually sufficient; consult a service manual for torque specs and disassembly steps.

• Common tools: socket set, screwdrivers, snap-ring pliers (if applicable)
• Follow starter rebuild instructions or professional service guidance
• Test engagement before reassembling and reinstalling the starter

Who is this for: This OLIFANT starter drive is intended for owners and technicians maintaining Polaris ATVs and Rangers who need a reliable, OE-equivalent replacement Bendix specified as 17-tooth (39 mm OD) with counterclockwise rotation. It’s well suited for routine starter repairs, midlife rebuilds, or restoring dependable starting performance on legacy Polaris models from the 1980s through 2014.
