If that bushing is failed and there is excessive play in the accy drive shaft that means the bushing has spun in the housing and the whole gear cover must be replaced. and possible the accy drive must be replaced as well. But to answer your question the front cover would need to be removed (Hard way )or the accy dr and pumps on the back of the housing is the easiest way to access the bushing. 132770 is the bushing part number if you want just try a bushing but i'm not sure you can gust get a bushing anymore, You prob can only get the whole cover Cummins would be able to tell you just provide them the serial number and part number to see if it is still a saleable part or if it has been obsolete .. I've never seen one work once it has spun in the cover. Please don't forget to rate/accept my service
To replace the front cover is a big job. The engine must be lifted up, the cam has shims that must be reinstalled to the proper thickness and the engine must be properly timed to name a few things.
Do you still need assistance?
