Gooday l am looking cat 422E servive mannual.
There are different Service Manuals depending on the Serial Number prefix of your 422E. For MAW & DSK-prefixes the Cat Publication Reference is KENR8835. For HBE-prefix machines it is RENR6470. A suggestion. Open a 30-day free trial subscription at scribd.com and see if the manual is available there. There are a number of backhoe manuals but it requires a subscription to see the full list of documents that are available.
