which would cover torgue specs for metric bikes?
You need a small one like 0-200 Inch pounds for cam cap and cover bolts. I also have a 0-50 ft-lb and 0-150 ft-lb. I have both beam type and clickers.which would cover torgue specs for metric bikes?
And the reason to use an inch/pound torque wrench for all but the biggest fasteners. The torque for everything from 4 mm up to 12 mm fasteners falls right in the good range of a 3/8 drive inch/pound torque wrench. All else falls in the range of a 1/2 drive foot/pound torque wrench.On a beam wrench it's also a matter of viewing accuracy: If you have a full scale wrench of 100 ft-lbs, an error of even 5 ft-lbs is very small in terms of visibility while using. Hence not wanting to use one for a torque value that is a small percentage of the full range.
16.5 ft/lb is 198 in/lb (16.5 ft/lb x 12 in/ft = 198 in/lb). Most in/lb 3/8 drive wrenches are up to 300 in/lb, so you see the reason for the in/lb wrench for most fasteners on a bike.The first thing I have to do is remove/reattach an engine mount bolt (to install an engine cage), which requires 16.5 lb-ft of torque. To be honest, I'm kinda' scared to remove it (for fear of my bike falling apart, LOL), but I'm thinking that if I buy the right tool, read all the instructions, use the tool correctly, trust the tool, then it should be alright.
I sure hope this works out, or else my bike is going to fall apart.
It depends on where the bolt is. Some are at a funny angle which puts the scale where you can't see it easily. I have both types of torque wrenches.If a beam style torque wrench seems difficult to use either an optometrist need be consulted or there is a question of skills needed to work on a bike. How hard is it to look at a needle on a scale? .
Harbor Freight sells clicker models, both in.-lbs., and ft.-lbs., for around $20 a piece. The maker claims 5% accuracy. For me, and my v-e-r-y occasional use, they work fine. I primarily use them on the oil drain bolts, and the filter bolt. Been using them for almost 6 years, no issues yet. The instructions did say to slowly apply pressure until it clicks, then apply pressure again, until it clicks a second time, to ensure proper torque. YMMV. Cheers!
