BBK without torque wrench?

[jcoahran]

is it possible to put a BBK in without a torque wrench if i do it carefully? i don't have a very wide range of tools :lol:

I strongly advise you to rent one from autozone, or borrow one.

Too tight will crack the rocker arm assembly (cam holder) and too loose will cause blow by. To have it right it needs to be torqued right.

You want a clicker style TW not the type with a rod

Ya, rent a $20 wrench?

if your going to use that one you might as well not use one at all
there are only a couple things i would buy from torque wrench
and thats anything that has to be calibrated sucha as torque wrenches and gauges

I always use a torque wrench for the cylinder nuts. It's important not only to use the right amount of torque, but to get it even. I dunno about even, but I tend to use too much force on small fasteners when not using a torque wrench. It's certainly possible to do a BBK without one, but parts stores will often loan them out for free. You have to pay the price of the wrench to use it, but you get it back when returned in good condition. The only thing I wonder about those is who has used them and dropped them and whatnot to throw them out of calibration. Still better than none.

Good advice!

For those fallowing mine, get a torque wrench!
Lol, i guess i should rephrase my quote. I use them, just not on my scoot.

I was given my fathers old sears pointer type torque wrench to do the heads on my 1835cc VW motor when I was 18. I have used it on every motor I have built since with no torque related problems. Using the right sequince is important too though. A race shop probably wouldnt use one but the average mechanic would have no trouble with one. A novice mechanic might be better off with a clicker though.

I don't either

I've never used 1 on all my scooter motor builds but I've been wrenching for 20+ yrs. Someday I'll get me a 1/4" torque wrench just to check my mental torque wrench.

I'm surprised how many don't use one. I even torque the nuts to spec when I am just mocking up with a degree wheel to be sure durations are right on. I'd use a computer program to figure out my porting if I wanted to guess at what's happening in the engine. Doesn't help that I've snapped GY6 studs twice so far in different engines at less than the proper torque spec. If I was going by hand and did that I'd feel like I must have over-torqued them and wouldn't realize a lot of Chinese 4T studs are kinda junk. :rant:

I think my obsession with proper procedure came from blowing head gaskets 10 times in a row on my Mustang. It wasn't at all related to install process or surface trueness or any of that, just a freak issue, but damn it made me not wanna blow another head gasket ever. That said, I still get leaks on my scooter's head gaskets doing all this extra work, so I suppose I'm the fool for spending the time on something that isn't really working. lol I guess at least I fail consistently.

Hi
My advice to you is to buy a good one. A quality torque wrench is one of the most useful and important tool's that you should have
Take care and ride safely
Yours Hank

i skipped it, i though that 1/2" torque wrench was a bit difficult to use on 10mm bolts. besides, you think the child that assembled the engine the first time used one?
