Long 610 Injection Pump Removal

Can anyone out there assist me with the correct way to be sure when you remove your Injection Pump on a Long 610 that when I put it back in how do I verify Timing is correct? I have a service manual for the tractor but it is a little vague on this (at least to me!). the removal part says nothing about timing at all. Installing cautions to be careful and step 1 is align all timing marks in the figure that lists INIEZ/CAV so is it fair for me to guess that the timing index of the crank needs to be on the INIEZ / CAV line? then i can reinsert the pump?

I am having the pump rebuilt as it leaks and loses prime and takes forever to get engine going even after stopping for a day or two. Hoping this solves those issues. Yes fuel does leak out of it in spots. Thanks
 
If I recall the last Long pump I repaired had a tapered drive shaft, and a key for gear alignment. There's also a scribe line on one pump housing ear flange, and a scribe line on the timing gear case, those marks USUALLY are aligned. Long as the pump is removed/replaced using those lines as a reference, and the key located into the gear correctly, NO flywheel timing is needed. Some Ford and MF/Perkins use the same setup. There should also be two threaded holes in the gear if I recall to use a bar and bolts to "push" the tapered shaft out of the gear too. There are some special features on the Long pump to be resealed too during repair. That's why I bench test each pump to verify no leaks.
 
Thanks for your help. I sent you an email to see if you do pump rebuild. I am looking to find a reliable technician to rebuild my pump and also possibly check the injectors. Thank you. Email is listed if you want to get back to me.
