What is the crank bolt size ?

Actually is the round exagonal head bolt that holds the crankarm to the BB.Usually an 8 mm hex head that pushes the arm into the square tapered bb.

It is the old school small bolt, the new style larger allen bolt on the shimano hollow bottom bracket will not work.

A Retrospec Crankset has a crank arm length of 165mm. No need to worry about pedal strikes!

They appear to be 152cm (doesn't say specifically, but there is a marking of 152 on the back of the crank and it measures close to that with a tape).

There are different bcd (bolt circle diameter) for different cranks. If yours is a four bolt pattern it is most likely a 74 bcd and this one would work. However, there are many five bolt patterns such as 110 for compact road and 130 for standard road. So find the bcd for your cranks and you will have your answer.

Hi Nick, I am not 100% on the bolt your talking about. However, I believe you are referring to the bolt underneath the black plastic stub in the middle of the handlebars directly in front of the seat. If so, a 7/32 inch hex/alan key fits it nicely. You'll want it tight too because I almost had an accident at how loose it was when it arrived.

I am using my engine for a custom built hydraulic log splitter. There are two bolt mounting patterns. One recessed around an inset circle and fits standard hydraulic pump brackets perfectly. The other is a square bolt pattern 'on top' of the circle. Those are I believe 5.25" on center, but I can't measure at this point because the pump bracket is mounted. I believe the documentation noted their size. Based on the bracket I am using, I would guess they are a very standard size because mine worked flawlessly...

they fit crank arms with 9/16 " threads which are the most common. one piece cranks have 1/2 " threading I think. So what do you mean by they don't fit.

Pedal bolt size should be universal; whatever pedals you buy should work. Just make sure you put the left pedal on left crank arm and the right pedal on the right.

They are 9/16". This is the standard size for all bicycles. I have mine mounted on a Shimano crankset on my Dawes road bike.

Look if the manual of your bike or the crank arm specifies the size, or if the size might be stamped on the existing pedal.If DIY no documentation available: Measure the hole diameter on the crank arm (at the inner side, opposite to the pedal) or take one of the original pedals off your bike and measure the threaded part, you'll need a caliper for that. (That's how I did :-)Hint: Clerks at (small) hardware stores and of course bike shops or fellow experienced bikers also could help with that.

I purchased a kit last year. There is no Crank bolt. The chain has three distinct colored links

what size time-set would I need for a 1982 chevy 350 motor crankshaft bolt hole thread

It says in the picture: English thread, 68mm(what the other guy quoted was his axle length that he bought to go along with it, and that needs to be selected according to the crankset you are getting, for proper chainring clearance and straight chainline)

Check your bolt size requirements in the owners manual. These are 20 in and 400 grain including a 100 grain head.

Look on the back side of your factory crank arms. They should have the length in mm (170, 175 etc). Also just make sure your new crank set will fit the splines of you bottom bracket.

9/16"-20 is the standard for bicycle pedal threads, left hand thread on the left side to prevent backing out under precession. These follow that convention.Old one-piece steel cranks sometimes have 1/2"-20 threads.Most pedals use 15mm open end wrenches to install. These do, and also take a 6mm allen wrench (although the recess looks a little shallow for putting a lot of torque into it, it is still nice for an on-road tightening, if necessary.

Pedal spindles come in two measurements: 1/2" and 9/16". It may seem similar but when you hold them side by side it makes a big difference. The good thing is that most Shimano cranks have 9/16" ports for pedals. This one should be 9/16"
