A mesh that is too tight increases friction, heat and bearing load; a mesh that is too loose concentrates load near the tips of the teeth and can produce chatter, accelerated wear or tooth damage.\u003c\/p\u003e\u003cp\u003eAfter installation, rotate the drivetrain by hand through a full revolution. The gear should turn smoothly without tight spots, binding or an obvious repeating high point. If mesh varies around the circumference, inspect shaft runout, bearing play, hub seating and mating-gear condition before operating the vehicle.\u003c\/p\u003e\u003ch3\u003e43T TOOTH COUNT\u003c\/h3\u003e\u003cp\u003eGS087 is the \u003cstrong\u003e43-tooth\u003c\/strong\u003e version. Tooth count is part of the transmission ratio, so substituting a different tooth count can change overall gearing, component engagement and compatibility. CEN also catalogs GS088 as a separate \u003cstrong\u003e39T steel spur gear\u003c\/strong\u003e; the two should not be assumed interchangeable simply because they are visually similar.\u003c\/p\u003e\u003ch3\u003eWEAR PATTERN DIAGNOSIS\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolished wear centered across the tooth face:\u003c\/strong\u003e generally indicates the mating gears are sharing load across the intended contact area.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWear concentrated at the tooth tips:\u003c\/strong\u003e may indicate excessive backlash or insufficient engagement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy scoring or discoloration:\u003c\/strong\u003e can indicate contamination, poor lubrication where applicable, excessive friction or misalignment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRepeated damage in one section:\u003c\/strong\u003e may point to eccentric mounting, shaft runout or a damaged mating gear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSharp burrs or chipped edges:\u003c\/strong\u003e warrant inspection of the complete gear train before continued use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eMATING-GEAR INSPECTION\u003c\/h3\u003e\u003cp\u003eDo not install a new GS087 against a visibly damaged mating gear and expect the new part to correct the problem. A worn or chipped pinion\/mating gear can quickly imprint its damaged contact pattern into a fresh spur gear. Inspect both gears, shafts, bearings and hubs as a system.\u003c\/p\u003e\u003ch3\u003eINSTALLATION CHECKLIST\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConfirm the transmission calls for CEN GS087 \/ 43T before installation.\u003c\/li\u003e\n\u003cli\u003eInspect the mating gear for chipped, hooked or heavily worn teeth.\u003c\/li\u003e\n\u003cli\u003eCheck shaft and bearing play before setting mesh.\u003c\/li\u003e\n\u003cli\u003eSeat the spur gear fully and squarely on its intended hub\/interface.\u003c\/li\u003e\n\u003cli\u003eSet backlash so the gears rotate freely without excessive looseness.\u003c\/li\u003e\n\u003cli\u003eRotate the drivetrain through a complete revolution and check for tight spots.\u003c\/li\u003e\n\u003cli\u003eConfirm all retaining hardware is secure before powering the vehicle.\u003c\/li\u003e\n\u003cli\u003eRe-inspect mesh and tooth contact after the first operating session.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eNOISE AS A DIAGNOSTIC TOOL\u003c\/h3\u003e\u003cp\u003eA sudden increase in transmission noise after service is useful information. A high-pitched whine can indicate overly tight mesh; clicking or rhythmic knocking can indicate a damaged tooth, eccentric rotation or excessive backlash. Stop and inspect before continued running turns a setup problem into gear or bearing damage.\u003c\/p\u003e\u003ch3\u003eLUBRICATION \u0026amp; CLEANLINESS\u003c\/h3\u003e\u003cp\u003eUse the lubrication practice specified for the transmission in which GS087 is installed. Avoid packing an exposed gear with grease simply because the gear is steel: exposed grease can trap abrasive dust and grit. In enclosed gearboxes, lubricant type and quantity should match the transmission design. Cleanliness and correct mesh are more important than excessive lubricant.\u003c\/p\u003e\u003ch3\u003eWHAT CEN DOES NOT PUBLISH\u003c\/h3\u003e\u003cp\u003eCEN's current GS087 product listing confirms \u003cstrong\u003esteel construction and 43 teeth\u003c\/strong\u003e, but does not publish gear pitch\/module, outside diameter, face width, bore dimensions, pressure angle or a universal vehicle-fitment list. GASHEAD RC does not invent those specifications. Match by the exact GS087 part number and the transmission's parts documentation.\u003c\/p\u003e\u003ch3\u003eGASHEAD RC NOTE\u003c\/h3\u003e\u003cp\u003eWith steel gears, failures are often blamed on the gear itself when the root cause is actually mesh, shaft alignment, bearing play or a damaged mating component.
