Dia-Compe 287 V lever installation?(10 posts)

Dia-Compe 287 V lever installation?sfrider

Has anyone installed these levers before? I am probably being an idiot, but how do you tighten the mounting screw to the bar when the lever is in the way? Do I need to punch out the pin to the lever and remove it so I can mount the hood?
Depress lever, insert 5mm hex.Alex-in-Evanston

When you depress the lever a little channel opens up that is just big enough for the 5mm hex. Feel around for the bolt head, it's in there. You need a hex wrench that is only 5mm wide for at least the last two inches or so of its length - i.e., not a pedro's wrench that is coated with latex and only tapers to the 5mm at the tip.

When you're loosening the lever to remove or adjust, be careful not to thread the bolt all the way out - it's an enormous pain to get back in.

doesn't line upsfrider

that's the problem. i tried depressing the lever and the bolt doesn't line up wit the space where you can insert the wrench. It can only be accessed at an angle. If I tighten it like that (with a ball-end hex wrench), I run the risk of stripping the bolt and or not getting it tight enough.
...what were they thinking when they designed this!
Did you remove the black plastic cap?The Walrus

The black cap that's kind of a rounded triangle, that screws into the top front of the lever; once this is off, you can swing the lever all the way down, and swing up that block through which the cable passes. Slip a
i four
mm (I just checked it) Allen wrench between the lever and the block, as in the photo (pay no attention to the ugly wrench...) and go to work.

If this is the lever that I'm thinking of, there's a hole in the front of the lever right?

Well that's just big enough for a hex wrench to go into to cinch up the binding bolt. I don't remember the hex size - maybe it's 3mm?

Hope this helps. Good Luck

Make sure the brake lever not depressed, and you need a long 4mmGlowBoy

I have these on my 'crosser and have removed and installed them several times this summer in my quest for the "perfect" handlebar.

Make sure the lever's all the way back in its "rest" position or the allen bolt inside will be blocked. I'm pretty sure it's a 4mm instead of the 5mm you use for most of your other bolts.

As mentioned, you'll need a wrench that stays narrow for at least a couple of inches in from the end. As with many things in life, finding the hole properly can be tricky the first time and occasionally problematic even after you've done it a few times. I sometimes shine a small light in there so I can see what's going on.
That's the trick...but tough to fully tighten.sfrider

Thanks for the advice, I was trying to do it with the lever depressed. Now the only problem is that it's hard to get leverage to fully tighten the bolt down with the long end of a skinny allen wrench.
Allen wrench tricksDale Brigham

I know a few tricks to increase torque (leverage) on the short "L" end of an allen wrench, which follow. Tricks 1-3 start with allen wrench inserted into the allen bolt on breake lever.

1) Get out your set of combination wrenches (open end/closed end). Put closed-end "loop" over short end of allen wrench. Try different wrenches to find one that fits so that you can use it as a lever to rotate (torque) allen wrench and tighten bolt. You'll figure out how it should be oriented to make it work (wish I had a pic here!).

2) Grip short "L" end of allen wrench with Vise-Grips or other grabby tool. Use that as your lever. Done carefully, this should not chew up (too much) the allen key.

3) Find a length of pipe or sturdy tubing that just fits (close fit good!) over short end of allen key. Use as lever.

4) Go to Sears tool department. Purchase set of Craftsman metric allen "T"-wrenches. Bask in glory of having perfect tool for this and many other jobs (these are nice T-wrenches!).

Good luck!
