MEP002A - MEP003A Timing Button for Onan DJ Series, Ambac M50 Injection Pumps inc. 50-2/4A-80A-9540A
MEP002A - MEP003A Timing Button for Onan DJ Series, Ambac M50 Injection Pumps including 50-2/4A-80A-9540A. Both new and most rebuilt pumps are sold without the timing button since each engine/pump combination must be individually timed and will require a unique button. You can find free manuals on our website to show you how to time your engine/pump as well as install the pump. Look under "Manuals" in our menu and then select "AMBAC M-50 FUEL INJECTION PUMP: 50-2/4A-80A-9540A MANUALS".
Note: You MUST choose one of the 16 button sizes based on your engine/pump's timing requirements. Note that the # value is NOT in order of thickness! The order of thickness, from thickest to thinnest is the following:
#16 = .134"
#15 = .131"
#14 = .128"
#13 = .125"
#12 = .122"
#1 = .119"
#2 = .116"
