Honda Odyssey Crankshaft Bolt Torque Help - Torque + Angle conversion to Torque

[dnschmidt]

Agreed that the Techangles are nice for what they do. But they don't appear to go up to 350 (only 300), and are $790 list. I was more questioning how often it comes up for the higher upper end, with the note that the usual response of why people NEED angle is swing room, and if that is true in those examples.

My point simply is there may be a market for a 350ft/lb wrench, either click or digital, depending on price. Hence why I said:

Again, not saying it will be the "empirically best" solution, but if it can meet a given need at a lower price point, then it has a market.

Mostly in response to this

Digital in this case has a disadvantage to a conventional clicker. The digital can only be read from one direction whereas the clicker is faster and you can tell when it's broken over from any position. When I need precision and have something on an engine stand I use digital. When it's in the car, exception being head bolts, I'll normally use a clicker. And that's from a guy that sells digital torque wrenches.

Not sure you read the description for this one, as it says "Audible Beep and physical buzzer" for the digital.

Again, I am not saying this will be the best answer for everyone, but "useless" due to eliminating the angle seems a bit too much, especially if it keeps the price lower due to that.

So I see what everyone is saying, just torque it to the specified angle, and the eyeball the angle.

I'm however very bad at "eyeball" method, so I was hoping a digital torque wrench that does angle would work for me. If I get one that can do up to 100 ft lb, and can do angle as well, would this be to small to use for my application?

You’re not building the space shuttle here. So long as you’re not Stevie Wonder, do your best to approximate the angle spec and you’ll be fine.

I really don’t think you‘ve read this thread. This isn’t the only thread you’ve started that I got the sense you didn’t read.

Non angle digital torque wrenches are far from useless. They’re faster to set, can have a larger accurate range, and a light and buzz are easier to see or hear in a loud environment. Obviously, angle and prevailing torque are useful additions, but saying something without them is useless is just Dennis’s snobbery leaking through.

"how do I convert 48 ft lbs + 60 degrees, to a final torque "
You don't. Post #5 covers it well.
My anecdotal experience with dampener bolts is put a bar on it and crank the bejeezus out of it to tighten. Haven't had one come loose yet.

A 350 ft-lb digital torque wrench without angle is completely useless. What's the purpose of the digital version if all it does is show the torque setting digitally? Craftsman had this **** 30 years ago and it was a bad idea then. Chris has had many great ideas but this doesn't seem to be one of them. The ad doesn't even mention if the units can be changed from ft-lb's to N-m which is what 80% of the specifications for modern machines use. The 91350 seems OK to me but the digital version I feel is a non-starter.

It does have N-m and other units.
It vibrates and progresses light colors to signal torque. You don't have to watch it.

You're correct that the 1st 1/2" anyone's made that can do a range up to 350 ft-lbs doesn't offer angle features, the goal was for someone who sometimes needs values in the 270's, 300's, 320's to not have to buy and store both a new 3/4" torque wrench and now 3/4" sockets too, using their existing 1/2" instead on those applications and lug nuts with the same tool.

It will be well priced, similar to many standard 250 ft-lb wrenches, while allowing for rechargeable use with 18650's too. If we priced this into or well into the $200's or something we would have failed at our motivation to make it.
We're not an Asian manufacturer adding tooth count to a USA made wrench and calling it the next best thing - not sure how that came up here as well, these were made to my drawings and materials requirements because of actual requests, for the above reasons. If you don't find yourself considering whether you need to pick up a 3/4" torque wrench and sockets you're likely not the target customer, but luckily no one is asking anyone to turn in their current useful torque wrenches - there won't be a marketing campaign implying you NEED these.

I resent that. My snobbery is clearly displayed at all times and doesn't need to leak through as it is readily apparent.

I welcome a discussion on the NEED for the digi tq wrench fron Astro. Like a PN.

Not a gotcha question, just curious. What passenger vehicles require 300ftlbs fastener torques?

I can imagine heavy equipment, big tractor trailer trucks etc. What is the application this tool was intended for?

 

[dnschmidt]

I don't think it's a matter of being able to go to 350 ft-lb as I can't think of anything not made by Kubota or Caterpillar that requires that much torque. BUT, THE EXTREME LENGTH of the tool is appealing because if you work on any diesels you're often dealing with 200+ ft-lb and normally sized torque wrenches (particularly if they are made by Precision Instruments) actually don't have enough leverage to easily work at that kind of torque.

As said before, the front wheel bearing nut on my F-150 ('04 RWD) is torqued to 265ft/lbs. Just as one example.

 

[Callelle]

Other than wheel ends, I can't really think of much that requires >250 ft lbs but also falls in <350 range. Most of the engines I work on, things that need to be torqued are often either in the 40-100 ft range, or if it's higher, it almost always has an angle requirement. Even if they had an angle feature, it might put it beyond it's range. Headbolts on an A26 for example is 230 ft lbs + 90 + 90 + 90. Older stuff like a MaxxDT is 176ft lbs + 90 so probably within the range of a normal 1/2". I like the idea of it, but the features seem to be in sort of a dead zone.
