'84 1150 rebuild

[dorkburger]

Agreed with Londonboards. I stripped one. It was shockingly easy, even for this weakling. You may want to spring for new seals for the bolts also. Im under the opinion that perhaps the rubber compresses over time and the bolts bottom out on the shoulder at the cam caps before they seal. Most of mine were leakers.

[wyly]

??? my cam cap bolts don't have seals.

[dorkburger]

Sorry, I was referring to the valve cover bolts that screw into the cam hold downs.

[wyly]

ah right, at 32 yrs old mine aren't looking too good I may replace them at some point

At the level of 8lbs you are better off going by feel.

I would never trust a torque wrench at such a low level. Trust your fingers

This is a CROCK, some of the WORST advice you could give someone!! I build engines EVERY DAY & use a Snap On, inch pound torque wrench to do ALL cam cap bolts, & even cover bolts with it, all between 7-10 ft. lbs, or 84-120 inch pounds. The cam caps torque spec is CRITICAL!!! DO yourself a favor & don't take advice from someone that doesn't know what they are talking about.

I agree it's a very critical area Ray, too loose or too tight can't be a good thing when the part you're fastening is in contact with cams that spin around as fast as they do. This isn't like tightening the bolts on a static crankcase cover.

I'm waiting for my digital wrench to arrive and if that doesn't work I'm not sure what I'll do, I certainly can't afford a $500-1000 for a professional quality torque wrench. I've looked for local rentals and there none to be had, and people that may have them aren't keen to lend them and I understand why. I don't trust my torque wrenches at the best of times thinking of doing this by hand worries me.

A Snap On torque wrench isn't 500-1000 dollars. I have 4 of them, an inch pound torque wrench, 2 of the same 5-75 ft. lb., & a 25-250 ft. lb. I USED to use the 5-75 lb for cam caps too, with NO issues, but recommend the inch pound for anything under 15 ft lbs.

You guys with your fancy tolerances.. kidding of course. I have an inch pound and a foot pound wrench, but ive never used them for engine covers and such. Ray, guess I proved your point or I wouldn't have stripped one......

[wyly]

I don't know where you buy your tools Ray but I looked up Snap-on a 1/4" was listed as $440USD, once converted to canadian funds that's about $520 then there's shipping, tax and customs charges...

The one I found was $150 tax and shipping, hopefully it'll do the job.

my head reassembly still on hold while I wait for my torque wrench to arrive ...so I wrestled the carbs into position today, very glad I purchased new rubbers for the carb/head that would've been near impossible with the old petrified rubbers.

[londonboards]

You need the right tools:

[wyly]

lol! yeah that would've been my situation if I hadn't bought new rubber.

The battle of removing the carbs was still fresh in my mind, the rubbers were as hard as hockey pucks, it was a beast of a task. I assumed putting the carbs back in with the petrified rubber would be many, many times worse so I bought new air boots for $100. It took me only an hour to install and hook up the cables using only my hands and a screwdriver, no hammer or wood required.

my torque wrench should've been delivered to my door today but the lazy arse mailman couldn't be bothered and left a "failure to deliver-No one was home" notice at the community mailbox down the street I was watching him from my driveway and he never came to my house...so now I have to go to the depot to pick it up tomorrow.

[steve murdoch]

Canada Post to the rescue again.
New carb boots are such a treat.

[wyly]

YEEES! I have my 1/4" torque wrench....and it works! now I can get back at it...price works out to about $7 per torqued bolt, ouch, better than a trashed engine I guess.
