If I use a perkins from a 550 massey combine will the injection pump from the tractor engine (354u64443) bolt on with no issues?
 
Maybe if you had the same vintage 354. I tried using a pump from a 74 510 and the drive was differen't. The 1850 used a quill shaft and the 510 had the updated drive..
 
The 550 engine will be the uprate drive, while the 1850 will be the small spline UNLESS it's been updated to the uprate drive too. Some uprate drives would still take the small spline shaft also. You will want the 1850 pump hydraulic head as it's 9MM, the 550 is 7.5MM plunger size.
