Wrench Tip: Torquing Unreachable Fasteners

by Nikita Rushmanov

Have you ever looked at your service manual for a torque spec, only to curse, “What the hell were those engineers thinking?” We certainly have, but there is always a way to get things done by the book. The perfect example of an impossible torque spec is the driveshaft to differential flange on a 240sx. In this case, it’s impossible to get a socket on the nut because there is not enough room between the flange and the differential housing. Additionally, the hex head of the bolt on the other side is jammed against the flange, so you can’t torque that either. As a result of this, a lot of 240 owners we know never actually use a torque wrench on their driveshafts, instead opting to torque to “2 uga ugas” with an open ended wrench. To compliment this, we’ve also seen a few 240 driveshafts rattle loose, or in some cases come off completely, punching holes in the floor pan.

So what’s the solution? Let us show you!

MotoIQ Wrench Tip - How to Gap Piston Rings

by Mike Kojima

Setting the gap on your piston rings is an important step to building an engine that performs at its best.  Getting your piston rings to have the optimal seal is perhaps the most critical aspect of good engine building.  Of course you want to spend time assuring that your machine work and cylinder wall finish is correct for the type of rings used but a lot of people neglect blueprinting the ring gap.


 

Wrench Tip: How To Fix a Faulty Key Fob

by David Zipf

If you drive an older car with keyless entry, you will notice over time that the buttons stop working.  The general solution is to simply replace the battery.  But sometimes that doesn’t actually fix anything.  Other times only one button isn't working while the rest are.  If this is the case, the real problem lies deeper and fortunately, it’s an easy fix with some simple tools and about 5 minutes of time.


 

Wrench Tip: How to Fix a Bumper Cover

by David Zipf

Fender benders suck.  Even a light knock can craze paint, crack light lenses, and put holes in bumpers.  While the damage usually isn’t structural, replacing all those plastic bits can be a real hassle and it gets expensive fast.  And then there’s paint: not only do you lose your car, but a respray is never quite as good as the factory paint.  Surely, if you have been in a minor parking lot scuffle, there’s a better way of dealing with plastic damage than to chuck the bumper and start from scratch?  Luckily enough, there is.


 

Wrench Tips #31: Cardboard Aided Design

C.A.D. - Cardboard Aided Design

by Dan Barnes

It was an epiphany when I walked into a race shop and saw the interior tin work of an under-construction Rolex GT car mocked up entirely in white illustration board, clecos and blue tape. I made a mental note: I can do that! I can even afford that! Now my projects turn out better with the use of old cereal boxes, scissors and tape.


Wrench Tip: Get a Jewelry Cleaner

by David Zipf

Cleaning small parts can be a real hassle.  If you’re rebuilding, say, a carburetor, with lots of little jets, needles, and pins and screws, it can be very easy to break or lose something.  Some parts refuse to come clean, even when scrubbed with strong solvents (brake calipers are a great example of this).  So what’s a car guy to do?

Wrench Tip: How To Remove a Bolt From Plastic

by David Zipf

I had the recent displeasure of being rear-ended in the Vehicross.  Luckily, the accident wasn't too bad (and we will get into it more in a later project installment), but the bumper cover did need to be replaced.  We decided to replace our damaged bumper with a used one.  The used bumper was in good shape, but we found a number of the mounting bolts were rusted onto what was left of the bumper support.  We would have to remove these bolts without damaging the new cover.  This would require a delicate mix of power tools, cleverness, and a basic understanding of heat transfer.
