The Honda CL 175 is a classic motorcycle that is well-loved for its versatility, simple design, and reliability. Like many pre-owned motorcycles, a bit of care and restoration is what they need to remain rideable. The front forks are one of those parts that more times than not need a little help. Of course, overhauling a fork will not only result in a much better ride from a comfort perspective, but it also helps to ensure that your Honda CL 175 rides as you want it to with better safety.
Rebuild The Forks On A Honda CL 175 | A Simple Guide (This guide shows you step by step all of the processes to rebuild the forks on a Honda CL 175.) From seasoned mechanic to DIY enthusiast, this breakdown will give you everything needed to theoretically revive that front suspension on your bike back to its glory.
How to Rebuild Forks on a Honda CL 175
First released in the late ’60s, the Honda CL 175 fledged its way into the hearts of dual-purpose aficionados. They can however wear out, contributing to poor performance, leaking oil, and sub-optimal handling over time on this classic bike.
One of the steps in restoring your Honda CL 175 is rebuilding the forks. That consists of renewing seals, springs, and fork oil, and cleaning and checking components for damage and/or wear. An appropriately overhauled fork means your bicycle will ride smoothly, corner well, and look like a motorcycle.
Why Rebuild Your Forks?
Front forks work to soak up bumps in the road, help to keep the bike stable and keep the ride smooth and comfortable. Eventually, things like seals, springs, and bushings will wear out, and this means that:
• Oil Leaks: Oil seeps through worn seals leaving you with less suspension.
• Damping Loss: Fork oil loses its shock absorption qualities, leading to a jittery ride as the fork hastens towards Jello-like stiffness.
•Corrosion and Pitting: Weather can destroy fork tubes and their function.
• Sagging Springs: Over time, springs break or lose their tension and cause a sag in the suspension.
A fork rebuild fixes all these problems, with your Honda CL 175 handling and riding like it should.
Tools and Materials Required
Get your tools and supplies ready before you start the rebuild for a smooth and easy rebuild.
Essential Tools
Socket Wrenches: For removing bolts and securing components
Lallen keys: They are sometimes necessary for the de-installation of some components.
Fork Seal Driver — To install new seals without damaging them.
Rubber mallet: To tap components into place without damaging them.
Drain Pan: in which one drains old fork oil.
Torque wrench — For tightening bolts to specification
Pliers: Circlip removal + small parts
Materials
Fork Seals; Worn seals can cause oil leaks.
Fork Oil: You can use fork oil of recommended viscosity for the CL 175 (typically 10W or 15W).
Spring Replacement (optional): Upgrade if the old springs are worn.
Tools Used: Rags, brake cleaner & parts washer to give stuff a good cleaning.
Grease: For lubrication of seals and other moving components.
Disassembling the Front Forks
Rebuilding starts with the disassembly of the forks. Follow these steps carefully:
Step 1: Secure the Motorcycle
• Jack the front-up motorcycle jack or stand the front wheel up
• Make sure the bike is firm right before and after.
Step 2: Removing the Front Wheel and Brake Package
• Remove and put aside the front wheel.
• Detach and safely hang the brake assembly so the brake lines are not bent.
Step 3: Loosen the Fork Bolts
Unloosen the pinch bolts on the triple clamps and slide the fork tubes out •
Step 4: Drain the Fork Oil
• Find the drain bolts on the bottom of the forks and unbolt them.
• Drain the used oil into a pan until empty.
Step 5: Disassemble the Forks
• Unbolt the fork caps with a socket wrench with spring pressure being cautious.
• Remove the springs, spacers, and inner bits.
Inspecting Fork Components
Carefully check each part for damages or wear that needs replacing.
What to Look For
Fork Tubes: Look for corrosion, pitting,g, or bends.
Springs: Examine for signs of sagging or loss of tension.
Seals and bushings: Change them if there are cracks, wear, or oil leakage.
Fork Oil: Look for dirt in the oil, suggesting a blown seal.
Replace vs. Repair
• Change any parts that are excessively damaged.
• Thoroughly clean reusable components before reassembly.
Seals, Springs, and Oil replacements
The rebuild itself centers around replacing essential parts.
Replacing Fork Seals
Clean Out Old Seals: pull out old seals with a pick or flathead screwdriver.
New Seals: Add a thin layer of grease to the new seals and use a fork seal driver to seat them evenly.
Replacing Springs
• If changing springs, make sure they are the correct Honda CL 175 length and tension.
Refilling Fork Oil
• Add the appropriate volume of new fork oil to each fork leg.
Compress the fork as many more times as possible till no air bubbles come alive, then seal it.
Detailing Fork Legs
Cleaning and polishing fork tubes | increases performance and aesthetics.
Steps to Clean Fork Tubes
Clean off old oil and grime using a parts washer or some brake cleaner.
Sharpen the tubes with detailed sandpaper or a sprucing compound, to just take out the slight, sponge-like scratches.
Protective Coating
• Keep it protected from re-corrosion
Reassembling the Forks
The last step in the process of a rebuild is reassembly.
Step-by-Step Reassembly
Put the clean and new parts back into the fork tubes.
Torque the fork caps and bolts to the torque specifications of the manufacturer.
Install the forks back into the motorcycle, paying attention to the alignment.
Suspension Testing and Tuning
When reassembling and windowing the suspension, proper performance should be tweaked and verified.
Testing
• Press down on the forks to test for compression and damping.
• Test ride the bike, feel the weight, and adjust as needed.
Adjustments
• adjust preload and damping settings (if applicable)
How To Care For Your Forks – Fork Life Maintenance
It takes you to some new forks but with regular maintenance at least!
Fork Seals: Look for leaks when doing a simple maintenance check.
Fork Oil Change: Replace oil every 10,000–15,000 miles or as recommended.
Wipe the tubes down regularly to avoid debris accumulation on clean fork tubes.
Use Storage Garage: To prevent corrosion (put away the motorcycle in a completely dry, covered area)Related Reading: How to Maintain Your Motorcycle Over the Winter.
