Snap-On Techangle Torque Wrench / Heads
#16
Is there an "insiders" place to buy snap-on tools where you don't pay retail? E.g., I see there's 1/2" Snap On Techangle Electronic Digital Torque Wrench on ebay going for $196 with a day of bidding to go and another BIN for $449. I don't doubt their quality, but prices are incredible.

I never get a price break.

You could use a breaker bar and a angle measurer thing you put on the wrench that has a little arm to hold it in place. But why not have a really cool torque wrench to make it perfect. I was able to get within 1 degree with my Techangle. Figured that was close enough. I don't know if you could get within 5 or 10 degrees with one of the add on things. I had very learned people who have built many engines advise me to not use one of the add on angle thingys.
I wonder what tolerance is on this 90*? I bet within 5* is good enough.
I can get within 5* just eyeballing with a breaker bar.

From page 15-116e
1st stage 20 Nm (15 ft. lb.)
2nd stage 90* torque angle
3rd stage 90* torque angle
From page 15-117
1st step 20 NM
2nd step 90* of rotation
3rd step 90* of rotation
4th step 90* of rotation
From page 15-118
1st stage 20 NM (15 ftlb)
2nd stage 90* of turn
3rd stage 90* of turn
Which of these is correct?
And, if 1 = 15 ft lb, 2 = 90*, 3 = 90*, a torque wrench should not be required for 2 & 3, correct?

Here's my reading ot it....
For 16 valve motors, the studs are done by torque in 3 stages to 90 Nm OR 20Nm followed by THREE x 90 IF the stud is galvanized yellow passivated. See WSM volume 1, section 10, pages 03-04. [LATE EDIT: There is disagreement between this and the 1983 Service Information Tecnik which says only TWO x 90 degrees after the initial 20 Nm for the yellow studs. BUT there is a tech bulletin in 1987 that calls for 3 x 90 degrees and is said to supersede all previous specs.]
For 32 valve motors, STUDS are 20Nm followed by THREE x 90 degrees, while bolts are 20Nm followed by TWO x 90 degrees. See WSM, volume 1, section 10, page 07.
WSM section 15, page 116e is for BOLTS (so, correct at 20Nm then 2 x 90 degress).
Page 117 is for STUDS (so, correct at 20 Nm then 3 x 90 degress).
Page 118 is back to BOLTS (so, correct at 20 Nm then 2 x 90 degrees).
If the studs versus bolts were a misprint, it would have had to have been misprinted in all 5 places above as well as the Technical Specification book for 85-89 and all the Service Informantion Teknic books for 86, 87, and 88. They are all consistent with above.

May very well be true Bill.
I think this is backwards. First and third ones are for bolts.

Who knows for sure? I've been massively incorrect many times before. But how about the guy that runs a 928 shop who told me after we found 28% leakdown and oil leaking from the heads on a 90 S4 motor his shop rebuilt, "It's 80 Nm, isn't it?"

Sometimes you may see items sold by students who get a lot of the truck brand items offered to them at half price, but they aren't supposed to sell them.
Industrial reps can apparently cut any deal they want.

Thanks! I figured the 3/8" wouldn't quite fit the bill for the head bolts. I'll probably go with the 1/2" like Jeff has since the 3/4" is showing up at almost $1,200 on the SO website . Even with "justify-any-tool" logic, I'd have a hard time coming to terms with a $1,200 tool that only saw very limited use.
As for eBay, I personally only buy tools from sellers with 100% positive feedback and a track record / background in selling tools. I've noticed that the 1/2" usually sells for between $290 - $320, and the 3/8" goes for $225 - $275, though a very nice one sold for around $320 last night. Not seen any 3/4" models listed. The guy looking for $450 for a 1/2" may be reaching a bit. Something I haven't been able to confirm is wether the warranty and free calibration on the Techangle is for the original owner, or the tool. If its the owner (and doesn't carry over for subsequent owners), I'd need a serious discount compared to new retail to cover the added risk / possible cost of ownership over the life of the tool.

I did some looking on the Snapon site and could not find the warranty period for the techangle, but I would be VERY surprised if calibration passed to the second owner or was free beyond the first year or so.
Snapon says the accuracy is +- 2% CW and +-3% CCW and good for 5000 cycles or 6mo whichever is shorter.

I noticed Amazon has quite a few snap on tools too. A 1/2" torque wrench (non-digital) and from 20-150 ft-lbs was around $150. Which seems like a much easier pill to swallow. Sorry for derailing the head-bolt topic. When I did it on the 84, I did it with paint marks and a craftsman torque wrench...

This is the 1/2 torque wrench that I use. I think its goes from 75-250 ft/lbs
not my pic by the way, of the net.

I've got one of the 3/8 techangle wrenches - very handy for almost everything on the 928, but when I need to do head bolts/studs I'll get a 1/2" one. Whilst its rated to 100ftlbs, the 3/8 one didn't inspire me with confidence the one time I tested it on a wheel nut, so I only use it in the 7-60 ftlb range (i.e. M6 up to the brake caliper bolts).
I picked mine up off ebay with a recent calibration (2 months) certificate for about $250 - but I was watching the ebay sales for about 3 months before my snipe won an auction. I'll be the first to admit that I won't get it re-calibrated until its at least a year past the last one (which will be in June) - but I'm a home user, and it lives in its case when not in my hand.
Any concerns/regrets about the price vanished the first time I used it - they're a great tool, and I will get the 1/2" one too when I have a need for it.
Oh - also, on the topic of how many 90 degree turns.. read this thread from cover to cover:

PS - Brad, can you remove or resize that insanely large image? Even with a 30" monitor its overly large.
