Torque wrench for rebuild

[Sawbladz]

I'm looking to buy a torque wrench for the rebuild I have planned but I don't know what range of torque capacities I need. I would assume the head torque would most likely be the highest but I don't know how low it needs to go. I was hoping to only need one wrench but will get both if need be.

A Snap-On 1/4 inch torque wrench ranges from 40-200 inch/lbs.

The 3/8 ranges from 15-100 ft/lbs.

The 1/2 ranges from 20-250 ft/lbs.

Snap on 3/8" drive. 15-100ft lbs.

/thread.

Yea, i think the 3/8 will do you just fine.

 

[Mr.PFloyd]

get a mastercraft 3/8 or 1/2 even. I have them both and they are just as accurate and durable as the snap ons.

Just guessing here, but I'd say the crank bolt has the highest torque spec, not the head bolts .

I've got a 1/2" drive Craftsman torque wrech that goes to 250 ft/lbs and a beam torque wrench for the lower torque ratings needed for the smaller things

 

[isnms]

^Yep
Crank bolt = 195 ft/lb

 

[Sawbladz]

Ahhh...knew I forgot something. Thanks.

<nodding> was just about to mention the Crank bolt

 

[Jeff Lange]

The obvious answer is get both.

I have a 1/4 drive one for small things and use the big one for everything else

 

[annoyingrob]

I use a 1/2" one for everything. If it's too low for the 1/2", it's one of those "It's tight enough" things.

Rob: Cam Caps
(something below the range of a 1/2" and close enough ISN'T acceptable)

 

[Sawbladz]

What is the torque on the cam caps?

 

[IJ.]

14 ft/lbs and have to be tightened in specific order

my big wrench starts at 20 ft/lbs.

wouldnt it be cheaper to buy a 3/8 and rent a 1/2 for the few things you need it for?

I love my precision instrument one. it's a 3/8. 16-100

I purchased mine when i was 19 but there cheaper now.

I have 2 of the big ones, one I got as a Christmas present when I was 15 and one I inherited from the Old guy that taught me motors.

I leave the older one in the car for the lugnuts

Good tools last pretty well forever if you look after them and it's nice having the correct tool for the job at hand anytime you need it.

That's why I have a beam torque wrench .
