Suspension Service - why, when, what & how
Why Service?There are two simple reasons to service suspension. To fix problems or prevent problems. These horrible problems can be split into two groups:
These can also be easy to spot (oil leaks) or impossible to spot until the fork has ground itself up internally and things get expensive. Longevity problems are best picked up during periodic service.
• Change lubricating oils within 3-6 months. This is to flush out any debris left over from manufacture, assembly and break-in.
• If it's leaking or feeling bad, then it's due.
• If you race, train or ride often then at least once every 12 months.
• Clean the sliding surfaces.
What? (Types of Service)
• Most important when forks are near new, to check factory oil levels, flush out debris and find any problems early.
• Rear shocks too. Removing the air-can, cleaning and lubricating will extend seal life.
• Protect your investment. Keeps your forks/shocks sliding smoothly to minimise wear and maximise performance.
• Replacement of all fluids and any seals or components showing abnormal wear.
• Resetting of any internal pneumatic valves (SPV, Boost Valve etc).
There are two options for this: Shop service or Shockcraft Service. We support both, supplying the parts and tools to get it done in your workshop, with our expertise and fully equipped suspension workshop available when you need it.
Shop Suspension Service:
What can be done in a basic, but clean, workshop?
• Periodic maintenance of suspension forks and rear shocks (lower leg bath oil, air piston lube, rear shock air sleeves)
• Fork oil changes & level checks
• Full service of the simpler suspension forks
• Fork seal changes
For basic servicing you will need:
• A wipe clean work area
• A decent set of tools (including oil syringes to accurately dispense, measure and height set)
• Work stands to hold the fork upright and inverted
• Paper towels to wipe the stanchions and lowers clean
• Drain trays to collect oil & a way to dispose of the old oil
• Trays for the parts you remove
• Assembly grease (Shockcraft stock both Prep M and Slickoleum)
• Depending on the specific fork you may also need:
• Fork oil for the damper side
• New crush washers for the lower bolts (we have 8 & 15 mm in stock)
What requires a specialist with a fully equipped & clean workshop?
• Anything you don't want damaged
• Fork cartridges that are highly pressurised (not common)
• Rear shocks which are highly pressurised (most of them)
• Forks and shocks that require special tools for disassembly and reassembly
• Parts over-tightened or damaged (aka muppet wrenched)
• Bushing replacement
• IFP pressure measurement & depth calculation
• Oil viscosity measurements
• Performance problems not fixed by a periodic service
• Major repairs & Engineering repairs (heli-coil, machining etc)
