THIS IS HOW YOU TITLE A SPECIFIC QUESTION DAMMIT. When someone tries to search for an answer, you type your best guess into the search bar. I like to use "titles only", simply cause searching the entire post is retarded. So, needless to say I've searched for the answer already and only come back with 3 pages of "hi flow or standard pump" threads. GEZZZ:doah:

Did I read the torque on the oil pump mounting bolt correct? Does 65lb ft sound right?

Thanks
:waytogo:


(ps) with a title like this, the next person SHOULD have no problem finding the answer IF THEY SEARCH! Pissy mode off :D
 
I have always torqued the oil pump bolt to 50 ft/lbs. I have never seen a spec in any book for it and I would be interested to know where someone seen it in a book.
 
50ft lb is what Ive always found and used.65 would be a head bolt spec or main cap bolt.
 
I have the Chilton's for Full-Size GM Trucks 1980-87

Book # 28622

It's on page 3-52
 
I got the Chilton 64-71 version and it doesn't specify the oil pump torque spec.I have seen 50lb several times from different sources and that's what I use and never had a pump fall off so Ill stick with it.Who's info is correct?:dunno:

I'm bettin' that's a typo.
 
I have the Chevrolet Shop Manual #ST-330-85, PAGE 6A2-39. It's brown and has Chevy logos all over it. Mine calls for 65lbs.

PS> The pump I pulled out was a M55HV. The pump I put in is a 10553, but the body is still stamped M55. However, the 10533 is the thicker body and bolt area. Strange though, both looked damn close in size, even though one was a HV pump. Dunno
