can someone help me ?I might have mixed up waterpump bolts on removal of my 1994 460. Does anyone have a length and bolt locations. Eleven bolts thru to engine block. thanks for any replies

 

Starting from the top and going clockwise: short, long, long, short, long, short, short, long, short, long, long.

I'm looking at a spare timing cover I have to tell you this. I can't quite remember, but I think there might have been two different lengths of the "short" bolts.

 

Thank you so much,Peter, for your reply. On mine, two of the longer bolts were 1/4 inch shorter.

Do you know where these shorter ones go? Can I install these 11 bolts and thighten them before putting on all the brackets for the AC, tensioner, ALt, power steering and air pump? I don't quite remember the exact sequence. Thank you again. Bill

 

So there are two different "long" bolts... I can't remember where they go though. I think if you just test fit the pump you should be fine. I don't think either accessory bracket shared any bolts with the water pump, but maybe I can't remember that either.

Don't forget to install that water pump backing plate.

 

Thank you, you helped me. I did have two bolts switched. I tried measuring depth of holes in block plus thickness of pump ad backing plate. If there were only two sizes, 2 1/2 and 4 1/4, it probably wouldn't be a problem, but two were 4 inches. Now, I have to wait for the pump to arrive. Most of these bolts were tough to get out. I was very converned about breaing them off in the block. I P B blasted all bolts. That stuff is great. Thanks again. Bill

 

can someone tell me the torque forbolts mounting waterpump on my 1994 460 engine? thanks for any replies
