How To Install a Clutch Kit on a 2015 Honda CRF50F
Shop parts for a 2015 Honda CRF50F Dirt Bike.Why replace the clutch on a 2015 Honda CRF50F?
The CRF50F is a youth trail/motocross-style 49cc fourstroke that uses a wet, multiplate clutch operated by a cable. Typical reasons to replace the clutch include slipping under acceleration, dragging or poor disengagement, inconsistent lever feel, hard or missed shifts, or a lever that develops excessive free play from cable stretch. Because the CRF50F is ridden in low speeds and tight conditions, repeated slipping from aggressive starts or clutch abuse accelerates wear.
Tools & consumables
- Basic hand tools socket set, metric wrenches, screwdrivers
- Pliers and snapring pliers (if applicable)
- Clean drain pan and fresh engine oil suitable for wet clutches
- Clean rags, mild degreaser, and a small brush
- New clutch kit (friction plates, steel plates, springs, pressure plate if included)
- Replacement gasket or RTV for the clutch cover
Preparation
Park the bike on level ground and secure it with a stand. The CRF50F's clutch sits in the engine's right case; depending on how dirty the bike is, clean the outside of the clutch cover to prevent contaminants entering the case. Because this is a wet clutch, you should drain the engine oil if you prefer replacing oil with the clutch service removing the cover can leak oil. Capture drained oil for proper disposal and have fresh oil ready for refill.
Removing the clutch cover
- Loosen and remove the clutch cover bolts in a crisscross pattern to prevent warping. Keep bolts organized by length.
- Gently pry the cover free. If it's stuck, tap lightly with a soft mallet; avoid bending the cover.
- Set the cover down on a clean surface and inspect the inside for metal debris or heavy contamination a small amount of metal is normal on highmileage units, but large particles indicate other problems.
Disassembly springs, pressure plate, plates
- With the cover removed, note the orientation of the pressure plate and springs. Take a photo if needed for reference.
- Loosen the clutch spring bolts evenly, a little at a time, to relieve pressure gradually. Remove springs and the pressure plate.
- Slide out the friction plates and steel drive plates one by one. Keep them in order so you can compare old parts and confirm correct reassembly order.
Inspection what to look for
Inspect each component closely:
- Friction plates check for glazing, uneven wear, saturated or broken linings. Deep grooves or worn linings mean replacement.
- Steel plates examine for blueing, discoloration, or warping. Slight color change is common; warping or severe heat spots warrant replacement.
- Clutch basket and hub look for notching on basket fingers where plates engage. Notching can cause grabbing and poor release.
- Inner hub splines and thrust washer/pushrod ensure splines aren't shredded and pushrod moves freely. Replace any parts that show heavy wear.
- Clutch springs compare free length with new springs; weak or sagging springs reduce clamping force and mimic slipping.
- Clutch cover interior check for burrs, gouges, or lodged debris that could interfere with smooth operation.
Preparing new plates and parts
Because the CRF50F uses a wet clutch, soak new friction plates in fresh engine oil for at least 10-15 minutes before installation so they don't starve for lubrication on first start. Lightly wipe steel plates clean they don't need soaking. Replace springs in matched sets and ensure any included pressure plate or thrust washers are installed as supplied by the kit.
Reassembly plates, pressure plate, springs
- Install plates in the same alternating order as removed friction plate, steel plate, friction plate, etc. Make sure friction plates seat fully in the basket and engage the hub splines correctly.
- Reinstall the pressure plate squarely on top of the last plate.
- Install clutch springs and tighten spring bolts progressively and evenly. Tighten by hand in stages so the pressure plate compresses uniformly avoid tightening one bolt fully while others are loose.
- Confirm the clutch pack is flush and there's no binding when rotating the clutch hub.
Reinstalling the clutch cover & oil
- Clean the cover mating surface and install a new gasket or apply a thin bead of appropriate gasket material. Seat the cover carefully to avoid pinching the gasket.
- Reinstall cover bolts and tighten evenly to secure the cover.
- Refill with the recommended oil grade for the CRF50F. Proper oil keeps the clutch plates lubricated and prevents overheating or accelerated wear.
Clutch cable adjustment & checks (cableoperated specifics)
The 2015 CRF50F uses a cable clutch proper cable free play is essential. Before heading out:
- Set initial free play at the lever per a comfortable, responsive feel enough movement to disengage fully but not so loose the clutch slips.
- Inspect the cable along its routing for binding, fraying, or kinks that can mimic clutch problems. Lubricate the cable if binding is evident or replace if damaged.
- Confirm smooth lever travel and that the bike shifts through gears with the engine idling. If engagement feels inconsistent, doublecheck plate seating and spring seating.
Breakin and final checks
After installation, run the engine to operating temperature and cycle the clutch through several gear changes in a safe area. Avoid heavy loads for the first few miles to allow new plates to bed in. Proper installation restores crisp throttle response, efficient power transfer, and predictable shiftingespecially important for tight trail or youth riding where clutch feel directly affects control.
Common causes of premature clutch wear
- Repeated slipping during aggressive starts, sand or mud that increases friction surface abrasion
- Heat from heavy use or wrong oil choice
- Neglected cable maintenance causing partial engagement
- Riding habits that hold the clutch partially engaged in technical sections
Final notes
Take your time inspecting mating parts replacing the clutch kit without addressing a notched basket, weak springs, or a binding cable will only repeat the problem. When done correctly, a new clutch kit on your 2015 Honda CRF50F brings back smooth engagement, improved throttle response, and reliable lowspeed control for trail and youth riding.
