A lot of our customers want to know what the steps are in our repair process. (Click here to go to a photo gallery)
The first thing we need to do is to give the cylinder a reference number and log it into our computer system. That makes it possible for us to keep track of where a cylinder is and what we need to do with it next. We also write the same number on any pistons or studs etc so that we can keep track of them too.
Most cylinders that come to us have had a hard, dirty life.
Before we start any serious work on a cylinder, we must clean it thoroughly so that we can REALLY inspect it for damage. We use a variety of cleaners and bead blasting techniques to clean cylinders.
If cylinders come in for repair with any studs, power-
Once the cylinders are cleaned and all the non-
After the cylinders are stripped, they must be sorted to go to the correct next operation. The three common choices are:
• Send for welding
• Send for boring
• Send for honing
If a cylinder is cracked, gouged or damaged any other way, we can usually repair it by welding and re-
Before we plate a cylinder, we want it to be a specific diameter. The boring operations are not accurate enough for this task, so we treat those as “roughing” processes and we hone the cylinders to our required pre-
Now that the bores have been made straight, round and the right size, we can apply our new electroplated coating. The cylinders are treated in a variety of chemicals to condition the surface before having anodes installed and connected, then the plating process is started. The plating time and current are calculated by computer and, after the time has passed, the cylinders are rinsed, dried and bead blasted to really clean them up and make them look like new again.
Once plated and cleaned on the outside, cylinders face a three stage honing process. “Pre-
Once the cylinder has been cleaned, we must next inspect it visually to confirm that everything we have done is to the correct standard. If everything is ok, it goes to the shipping department with a Quality Control tag that has been initialed by the inspector.
We carry out a final check that the correct work has been done, that it’s to the correct standard, that any pistons, studs etc are being returned with the cylinder, and that the completed package is well protected against damage during delivery.
