Hello fellasLet me communicate you all that I am a newbie into the RV world, and buying my 1993 Safari Continental has been a journey. Since I bought the rig I've been fixing a number of things (mostly maintenance, and inside the couch stuff) right now I am faced with a problem since the motor harmonic balancer has an abnormal movement, and needs to be changed, however, my most trusted shop has been having difficulties getting that part of the motor (harmonic balancer) because we can't find the serial number.I would highly be appreciated some help with two things:1.- someone that has the same RV could provide me with the engine block serial number, please.2.- some insight on knowing where the serial number of the motor hides?Again the goal of this request is to be able to know the engine block serial number so parts department can track it correctly and get the appropriate piece for the motor.SpecMade: Safari ContinentalYear: 1993I believe it is a Cummins 8.1, 250hp diesel pusher with Allison transmission.Thank you, thank you thank you in advance and looking forward to your responses.
