IMPORTANT:
49-tooth UPPER idler gear in the PowerTech 4045/6068 timing gear train. Helical cut. Do NOT confuse with lower idler RE56369 (43T) — different tooth count, different position. Both must be installed correctly for proper valve and injection timing.

Used in JD 5415-6420 tractors and 7210-7520 series. The upper idler transmits rotation between the crankshaft gear and camshaft gear. A worn idler causes timing drift, rough running, and potential valve-to-piston contact. Inspect bushing bore and shaft for wear.

⚠️ UPPER idler (49T). Lower idler (43T) is RE56369 — NOT interchangeable.
