85 740 won't start

I had the pump rebuilt and it is back in the car. I am installing the timing gear now and need the tool that keeps the pump from turning when torquing the nut (5193 I think). Does anyone have a drawing or dimensions, I have access to a machine shop to make one.

About a 7/16 deep socket.

Did the shop have any information for you about the failure mode?

7/16 deep socket will work like a charm IF I can fit it between the gear and the firewall. There is just no room to do the work. What about torquing? I dont see how I can fit a big torque wrench anywhere. Of course the book shows torquing it off the car, but I didn't see a way to install the bracket bolts to the block once the pump was attached.

Unfortuantely I was traveling for work, so the wife picked up the pump from the shop. I will call them later this week and see if they have any info on the cause of failure.

This is where D24 Special Tools come in handy. You need the 17mm - 1/2" square drive dogleg wrench!

It hugs the rear of the IP pulley then bends toward the front, clearing the firewall. Torque wrench can insert from the front.
See sticky D24 Special Tools for reference.

I did this once from below, after removing the fuel filter housing. A little tricky getting the bolt started but not too bad overall!

Tranny mount shot? undo it and jack the tranny till it touches the tunnel, there will be a bunch more room.

Not too bad with a gearwrench and a stubby.

OK figured the mounting out. Now on to the timing. Is there reason I can't just use a magnetic base for the dial indicator, rather than the special adapters that thread into the pump?

[morgan1227]

well i guess i can use the mag base because it seems to be working. any tricks for installing the rear timing belt without removing the cam sprocket? thanks
