Probably best to return it to the manufacture for repair.
Trigger, cocking lever, Spring, Piston tube around the spring. BB loder and barrel
that's so you can pee on them without any difficulty
It depends on the model. Some manufactures will sell you one or replace it if it is under warranty. Or check the web for "air gun repair", there are shops that make a living repairing airguns.
In a 2 stroke engine the piston itself is the intake/exhaust valve, instead of having separate valves as in the 4 stroke. The odd shape of the piston is the location of these valves.
In most cases, no, however if you are having issues getting the piston into the caliper, it may be seized, or it may be a turn in caliper.
8 dollars each to press new rods on pistons.
One of the parts in the piston are the piston head,
If I'm correct you're having trouble retracting the piston on the caliper. If I'm not then don't read anymore. You need to turn the piston clockwise while applying pressure against the piston. The easiest way is in a large vise with a socket against the piston while using channel locks to turn the piston. This is if you don't rent the special tool for this specific task. Don't feel bad I got the answer the same way you did. good luck
Piston never rotates. Piston moves up and down or to and fro. Pistons in some marine diesel medium speed engines (500 - 1000 rpm) have rotating pistons. Instead of having a gudgeon pin like most 4 stroke engines, these pistons have a spherical bearing. Inside the piston skirt is a circular ratchet system that rotates the piston as the connecting rod swings on each stroke. At 500 rpm, the piston rotates at about 10 rpm. Advantages are less wear, better lubrication and hence longer life.
Signs of bad piston and rings in a lawn mower engine include excessive smoke from the exhaust, particularly blue smoke, which indicates oil burning. Additionally, you might notice a loss of power or difficulty starting the engine, as well as increased oil consumption. If you hear knocking or rattling noises during operation, this may also indicate issues with the piston and rings. Lastly, check for oil leaks around the engine, which can signal worn rings or damaged piston components.
A bent engine piston is a reference to the piston rod. The piston cannot be bent, but the piston rod can be bent.
The piston rings create a seal between the piston and the cylinder wall.
