It's a double piston arrangement (one large and one small on a shared reciprocating con rod)

The problem is releasing the con rod from the drive without damaging the con rod! It's tricky, and needs a decent workshop set up to do successfully.

If you have the drier kit give it a go as often that's all that is needed. Unless that is, the compressor has been "overrunning" due to a fault, which can seriously damage the piston seals and sometimes the motor. yµ (idµ - eAµ) ψ=mψ

I’ve been down this road and struggled to get a UK supplier for the piston seals. There is a supplier in Ukraine with detailed video’s but he may be busy right now....

There is a guy in the USA who started a thread on the same topic

In the end I didn’t want to buy a bench press for just one job (maybe one day) and went down the lazy mans route and brought a complete compressor (including the L shaped bracket FFS) for £120 from an ebay supplier in Birmingham. Certainly Chinese but 2 months later all is still fine.

Think that's what I will do
