Proper way to tighten oil pump bolt w/removed Balance shafts?

[SnowBird]

Yeah, the shafts are gone so the pump gear is just gonna wanna spin and I have the pump packed with grease, so to keep it from free spinning and throwing all the grease outta the pump how can I keep it stable?

I was gonna wrap my old timining belt around the gear and have my buddy hold the belt tight while I tighten it, (if you can picture what I mean). Other than this I am clueless.

I'll tell you how I did it, however, the best way would be with the proper tool.

Put the oil pump timing belt sprocket on and snug the nut. Place the shaft of a regular screwdriver against the right side of the oil sprocket timing mark (small piece of metal that protrudes out, left of the bolt you are trying to tighten and just above and slightly to left of oil sprocket) then put the tip of the screwdriver into a groove on the sprocket. As you tighten the bolt, the sprocket will turn to the left and the screwdriver shaft will jam up against the protruding timing mark so you can tighten the bolt.

I would do this with the oil case already installed on the engine. You need to be careful that the tip of the screwdriver doesn't slip out of the sprocket groove when tightening the bolt. Not only could you scratch the oil sprocket, but you could hurt yourself. I have done a few like this without problems. Don't over torque the bolt. You could possibly break off the protruding timing mark.

I hope I was clear. If not, let me know and I will see if I can take a picture and post it for you.

By the way, this is the same method I use to torque the sprocket nut, except the screwdriver goes on the opposite side of the timing mark.

^^That is how I did it, but like the poster said, be careful. When I was taking it off the donor motor, I snapped the timing mark right off. It was a junk case, so it didn't matter, but you can bet that I was much more careful when assembling it on my motor.

Ummm... don't you just hold the back of the stubby shaft with a wrench or throw it in a vice and tighten it down? That's what I did. You have the front case off, correct?

If you do the free mod like I did (cut off the rest of the shaft with a hacksaw), you don't have anything for a wrench to hold on to. You can't even use vice grips because you will scratch the smooth surface where the oil rides.

Ah, gotchya. No wonder I was so damned confused.

I used a chain wrench and a rag (and card board) around the sprocket. I had a friend hold the chains wrench while I tightened the bolt...

Take an old timing belt, wrap it around the sprocket and hold while someone else torques the nut. Or . . .

snug the nut up . . . install the timing belt . . . use a breaker bar on the crank pulley bolt to prevent the whole assy from moving and then torque the nut on the oil pulley.

I'd not recommend using a few teeth on a new belt to hold the torque. Use the old one, most of the way around. Use Vise-Grips as a handle. Blue Loc-Tite.

Thanks to all. I should have put it on when I had the case off months ago. I mess around with it and use some blue loctite, thanks to everyone for throwing some new ideas at me.
