How many bolts hold pump on CAT 289D?

[FLYWHEEL PRIME]

The reference photo is from engine removal instructions for my 289D (thanks Nige). How many bolts hold the pump on? I can only find 1 on the "driver" side (if you're looking forward in the machine, on the left). Is there another identical 12 point 14mm bolt on the "passenger" side? I can't see a damn thing that far back even with my flashlight on, maybe I'm an bigger moron that I thought.

2 x 12-point head bolts (ref #3) - 1 each side. You need that special wrench extension adapter mentioned in the R&I procedure in order to access them.

I've got that tool, just typical shop manuals, 3 hoses I'm gonna have to remove on the hydraulic tank to access the right side. Took machine to dealer to clear codes last week and one of the mechanics "accidentally" left the OEM tool in my cab.

And for anyone in the future looking to pull the motor in these, shop mechanic said they don't disconnect anything on the pump. Leave all the hoses on, get the bolts out, ratchet strap the pump towards front of machine. Yank engine and be done with it. The hoses and everything will support the pump just fine, put a block underneath it just for grins though

I'm probably gonna need OEM tool on other side, but this worked as an emergency setup.

Stubby 12 point 14mm ratcheting wrench. Short length 3/8" drive ratchet with a 1/2" drive adapter. Put the 1/2" adapter in the open wrench end and use as a leverage point. Required cussing is 7/10.

I use a torque adapter.

Yep its a PITA. Repairing those machines will either teach you patience or make you want to throw stuff around the shop.
