Torque Specs

Before you I get blasted with the "if you had a shop manual"... I don't have one, sorry. :grin2:

I'm not sure if they matter from year to year, but my engine is a 302 out of '71 Mustang. I need the following torque specs:

Oil pan
Intake manifold
Timing cover
Water pump
Oil pump
Flywheel (Manual transmission)
Bell housing to block
Transmission to bell housing
Harmonic balancer
Driveshaft to rear pinion
Main caps (Replacing rear main seal)
Fuel pump
Fuel pump eccentric (cam)

I'm also replacing the valve stem seals, so are there any specific torque spec to tighten the rockers down to? They are just stock rockers.

Did I miss any? The only thing I am not doing is pulling the heads.

Thanks!

On a 71 they should be 'positive stop' rocker arms/studs. Should be 17-23 ft lb

Did I miss any? The only thing I am not doing is pulling the heads.

Thanks!

OK, So you don't have a shop manual, is there a reason for that, financial or whatever ? You know you can order one thru Amazon pretty easily.

If you can't afford one, (I've been there) PM me and I'll buy you one.

I understand helping out with these kind of questions, but it's my beliefs that peope learn more by showing them how to help themselves. (Yes I know that attitude might make me a dinosaur.)

Z,

I've just never gotten around to it, however, this site is such a great tool that supplements or even supplants a shop manual, that the answer to everyone's questions should not always be, "look in the shop manual". That's not an attack on you or me trying to be a smart *****, but that saying is so cliche' like "use the search function". If everyone has a shop manual, what would be the point of this site? Funds are not an issue with a $250k salary, but thank you for your kind gesture. You have been very helpful to me in the past, Z, so please don't take my response personal... I get what you are saying.

Guys like you, Bart, Paul and others have many shop manuals stored in your heads and are a wealth of knowledge and always a great help to guys like me on this site. My Dad was old school as well while he was alive and had every Chilton or Haynes manual for every make, model and year car ever made. He made his living with his hands, which to me is some of the hardest work on the planet. To say that I am slaving away for my salary is a shot in the dark, knowing that you have no idea what I do for a living. I did almost 22 years Active Duty Air Force (Special Ops) before I retired last year and I am an engineer that works in my office, from home, and travel when I need to. I wake up when I want, play with my 2 year old daughter for a good portion of the day, as often as I like, and come and go as I please, happily. There are no shackles or chains in my life and going to work in my PJ's all day long is the furthest thing you could compare slave labor to. :grin2:

If I am ever in your neck of the woods, I will glad to share a beer or two and a conversation or two with you. Your generosity and willingness to give the shirt off of your back, just like I would for others, goes a long way in a world where not much of that is left and is very hard to find.

:cheers:

Don't take it so personal, I don't need to know what you do or did for a living to say you are slaving away for the salary. It's just an expression , not an indictment. I'm glad to be retired. You're glad to be working . Everybodies glad, YEA !

PS the offer still goes for the shop manual, would love to put you on my Christmas list. Giving is the best high.

zray, I'm broke. Wanna' buy me a shop manual?

No, just kidding. So far, I've gotten by with excerpts that I've found Online... pieces specific to whatever part I'm currently working on. For me, this is just a stop-gap solution as I know that I must eventually squirrel away funds to buy a manual (and I will, I promise).

I never said I wouldn't buy one, and I even apologized for not having one from the get go. I'm sorry I went against the 10 Commandments of VMF and asked a simple question about torque specs that Bart so easily answered (and very quickly I might add), without having a shop manual in my hand.

This site is great for asking questions, even if you don't own a shop manual. That's what all of these sites are for, to get questioned answered. So yes, the peanut gallery is a little late to the party this time.

Oh, and guess what... I got all of the info I needed, all without buying or owning a shop manual. :pirate:

You are missing the point, Pete! I acknowledged that from the very beginning, and I'm not denying that having a freaking shop manual isn't going to help me, even though my car will be the furthest thing from stock when I'm done with it. If my car was completely stock or concours, there wouldn't be a better manual to have. That's not ignorance, but your comments show you don't read very well.

Tim,
some of us are proposing additions to the VMF format. There would be a checklist before an inquiry is allowed into the reply field.

1.) have you tried the research field ?
2.) have you googled, giggled or tweeted?
3.) do you have a shop manual, tried borrowing your friend or neighbor's manual?
4.) have you spent years figuring out how to find/follow a procedure in the manual?
5.) swear to buy a shop manual and learn to use it before your next inquiry.
6.) fill out at least a little of your profile so we know where to find you to beat you with a wet noodle.

Swear to enjoy the hobby,
Slim

Slim,

I understand all of those pertinent questions, but this is not a one size fits all. Most of the time people need information on the fly or very quickly and people have no problem producing the answer, on the fly and very fast. How are you going to rid people of answering yes to all of those questions, with no way to verify. I've seen this over the years all different forums and it never works out the way they though it would.

Is the concern that there are too many posts and questions, and over time these take up storage space on the servers that VMF is hosted by? I have no problem paying for a subscription that I am going to use on a regular basis, just like I pay for this site because I appreciate the knowledge fountain that people bring to the table. Throwing up some funds to maintain something I use is no big deal. I like to be able to tap that resource as well when I need answers.

If people feel this place is a job, answering questions, then they should find something else to do with their time besides post here and complain about people not having a manual or using the search function. I'm not saying that is what you are referring to, and this is not directed at you, but this site is the best around and sometimes people take the fun out of our hobby with petty remarks and responses. I am always very appreciative of the responses I get to my questions, and the professionalism and willingness to help others from the people on this site is what brings me back and makes me want to help others as well.

All this because I didn't have a shop manual... :shrug:

This brings up a pet peeve..... I just wish that people would do TWO things... 1. Fill out where they reside in their profile and, 2. Put a brief description of their car (year, body style, engine, trans) in their signature. This would eliminate a lot of extra questions or guessing.
