The
list below is intended as comprehensive check list to
help you and/or your mechanic keep your Morgan running throughout the
year trouble-free. It is
intended as
an annual or 10,000 mile 
servicing but will reap benefits whenever it is done.
Of course, it should be mildly modified to reflect each particular models differences. It is a work-in-progress
and will become more interactive over time with more links to detailed explanations.
Any contribution you feel is missing will be welcome and merit a credit.
The GoMoG Manual sections will supplement this guide, especially with specific issues to be repaired rather than maintenance per se. This effort is primarily a big dose of preventative medicine.The goal is to reverse the marque's current reputation, developed as much from a lack of owner effort and knowledge as current build quality and design. You can stagger the work over time if you so choose.
We remind you of the safety aspect when carrying out this work if you are unfamiliar with the good practices required to avoid any injury. While working around the car, one should also inspect the condition of the chassis and bodywork for damage or corrosion. We also work with a set of spanners and screw drivers at hand to test bolts and screws as we go.
No list is completely exhaustive, but long experience shows this one has an excellent chance of keeping you far more trouble free than others. If you do not choose to do it every year, get a price from your mechanic to do it. It should take a capable professional two days to complete. We suggest you print these pages and check off each task as it is done. If you have a question, have yourself or your mechanic click the task where you have a question..and send it on to GoMoG!
