Caterpillar D2 D4 starting engine main bearing std nos
New old stock, Caterpillar starting engine main bearing part # 4F9417 (STD size) to fit all older D2 and D4 crawler tractors . This is the main bearing for the flywheel side of the starting engine...... Check your parts books to see if this vintage part fits your needs..... These are very pricey from Cat.
