ASV RC 30 with Cat 3013 engine...

Been a while since I been here, haven't had much to complain about, I suppose. Have an engine question, Cat 3013 (3 cyl, 31.4 HP), A/R 177-9706, Serial # 4XD00805. It is leaking across the top of the injector pump, looks like across all 3 outgoing lines, at the plate, that holds them. You can pump the primer bulb, with the engine not running, and see the leak. When machine is running, the bulb is hard, and there is just barely a seep, if it's not just leftover diesel, from it leaking, while not running.

Questions I have:

Anyone have the R&R instructions? I plan on removing, having the pump rebuilt (local rebuilder says $100/hole), and then re-installing it.

I understand this pump is timed by how many shims there are, between the pump, and the housing. Any fear of it changing the timing, just from a R&R? Machine has 2000 hrs on it.

Torque values for the bolts to block?

Any tips?

Thanks for any info, I can't find a manual for this motor, and don't trust the manual sellers (often out of the country) who want $260 for it. Cat doesn't seem to be too user friendly, on motors that aren't in their machines...:Banghead:Banghead
