Technical notes
The 194-4897 is the exhaust valve used in the cylinder heads of Caterpillar 3500-series diesel engines, covering the 3508/3508B/3508C, 3512/3512B/3512C and 3516/3516B/3516C families in industrial and marine ratings. It carries a 2.205 in head, 8.622 in overall length, 0.495 in stem and a 45-degree seat angle, with a Stellite-faced valve seat to resist the high exhaust-gas temperatures and seat recession typical of heavy-duty marine duty cycles. On the 3512B specifically it serves as a direct OEM-numbered replacement; distributors commonly cross it with companion exhaust valve 468-8825 and supply it per valve (often in sets of eight for a head). It is a diesel-engine part, not for the spark-ignited G3500 gas series.
