How to Install a Shimano HG or IG Chain

Removal and installation of a Shimano HG or IG chain pin.

In this tutorial, we will learn how to remove and install a connecting pin on a Shimano HG or IG chain. These type of chains always require a special replacement pin that has larger peens.

Tools

For this job you will need a Shimano compatible chain tool such as the Park CT-3, and a set of pliers for breaking the connecting pin after installation. You will also need a black Shimano replacement connecting pin for 6, 7 or 8 speed chains, or a silver pin for 9 speed super narrow chains.

Chain Pin Removal

The first step is to break your chain using a chain tool. If you have previously used a replacement connecting pin, do not disconnect on that pin. The replacement pins can only be used once. Break the chain on any previously unused pin. When you push the pin out, it may be difficult as it will widen the plate holes on its way through. The replacement pins have wider peens to make up the difference. Once removed, discard the old pin.

Chain Pin Installation

When installing a chain, always place the chain in the chain tool grooves furthest from the handle. See the tutorial titled “How to use a chain tool” for more detailed instructions.

Push the replacement pin in with the narrowed end first, then tighten until the narrow end is fully exposed on the other side. The wide end should protrude equally on both sides of the chain.

Now using your pliers, break off the narrow end of the pin. If the link feels stiff, place the chain on the inner grooves of the chain tool closest to the handle, and tighten it just a bit until the link rotates smoothly. For more tips on loosening stiff links, see our tutorial titled “How to loosen a stiff chain link“.

I just registered here to ask for help. I have this bike; https://www.bikepedia.com/QuickBike/BikeSpecs.aspx?item=91408 Which I rescued from the trash. I know how to do the basics, like changing a tube or tire, but I don't have a lot of experience replacing parts, or doing much bike maintenance in general. To be honest, I'm not a hardcore cyclist. To me, the bike is mostly just a way to get pla...

Shimano's gearbox patent

Lastest post 3 days ago

So I read about Shimano filing a patent for bicycle gearbox both for MTB and road bikes. What are your thoughts about it? They must be serious about it and definitely have the R&D capacity compared to the existing bicycle gearbox manufacturers. Looks like an ebike motor. I've always been (and probably will be) a derailleur boy though. https://patentimages.storage.googleapis.com/ac/c6/46/60b59...

Chain wear to 0.75 too fast

Hi, got a fresh new KMC chain back in August for urban commuter bike. Have lubed it twice during this time, and weekly I cover around 30 miles on the bicycle. Measured chain wear yesterday ... it's worn already until the 0,75 mark. Isn't this too early for a chain to be done??...

Inner Tube Issue

Lastest post 1 month ago

In the spring I installed a new Fenix 26 x 1.90/2.125 inner tube on my year old mountain bike front wheel. It has been fine all summer until my last ride this fall. The following day after my ride both front and rear tires were flat. I thought that they might have lost air due to the cooler temperatures. But that was not the case. The tubes had failed. The tubes were inflated to the recommended 50...

Walmart bikes are better. Seriously! I knew that it would need some work because you do...

Oil can spouts

Lastest post 2 months ago

Years ago, oil cans had long spouts. Even the throw away cans had long spouts, but makers started putting little nubby spouts on the cans which makes it hard to get into some places such as my bike derailleurs. To oil those I have to pour oil onto a screwdriver blade and let it run down. The cans of '3 in 1' oil I used as a kid, on my bike, had a long spout. So after digging around I found cans w...
