The former 5I-7543 Plate (1) is now replaced with a new 222-8202 Plate in the 178-6519 Front Gear Group and the 212-8550 Front Gear Group. This product update is retrofitted as service replacement parts to all of the above listed machines. This improved plate is also effective with the 3066 Engine (S/N: 7JK57827-UP). The assembly and hold-down 5I-4936 Bolt (2) is also replaced with a flanged hold-down 222-8212 Bolt. Also, the 7X-0796 Lockwasher is not used with the flanged hold-down bolt. See table 1 below for comparison of the former parts versus the new parts. The former plate was 4.50 mm (0.177 inch) in thickness and the new plate is redesigned to 6.00 mm (0.236 inch) in thickness. The effectivity and adaptability for the new front gear group is listed in table 2.
