The upper face of a piston assembly is called?
Crown
How is the piston pin installed in the piston and rod assembly?
Some are pressed in and others use a floating pin held in by retaining clips on each end.
What is the purpose of gudgeon pin?
I believe a gudgeon pin is what the British call a connecting rod pin (or wrist pin or piston pin) in a reciprocating assembly, (piston, connecting rod, crank ) It connects the piston head to the connecting rod.
How do you rebuild a cr500 motor?
Two stroke engines are very easy to rebuild. The transmission component is not. The typical rebuild of a two stroke engine consists of removing the cylinder and replacing parts on the piston assembly. Before you order any parts, inspect the cylinder wall for wear and marking. If the cylinder is damaged you will need to get it machined and then order an oversized piston and ring to go with it. If its not damaged, order a standard (or performace) top end rebuild kit wich comes with a piston, piston ring, piston pin, piston pin bearing, and gaskets. So, for your standard rebuild of the top end you would remove one of the snap rings on either side of the piston pin. This will allow you to push the piston pin out from the opposite side. Once the pin is out the piston will come off the connecting rod. Take note of the piston orientation for assembly. The piston pin bearing will now be accessable (you will find on the connecting rod where the piston pin attached the piston). Minor assembly of the piston prior to installation makes it a bit easier to assemble. Place the piston ring on the piston and align the gap with the small pin you will see in the ring groove (turn the piston ring until it falls into place). Install 1 of the snap rings in the piston where the piston pin slides through it. The piston is now prepped for installation. Place the new piston pin bearing in the connecting rod with some assembly grease to hold it. Place the new piston onto the connecting rod so the hole in the piston matches the hole on the connecting rod. Slide the piston pin through the piston, connecting rod, and into the other side of the piston until it contacts the snap ring you installed earlier. Install the last snap ring into the piston to hold the pin in place, cover the outsides of the piston in assembly grease and lower the cylinder onto the piston. If you don't have a piston ring compressor you can hold the piston ring tight to the piston with your fingers. If you encounter any resistance when your putting on the cylinder you can LIGHTLY press the piston ring into the piston with a small slot-head screwdriver. Once that is together you should look up the torque specs for your make/model or if your not that picky just tighten them up at your discretion. If your looking to do anything on the bottom end of the motor or in the transmission I would HIGHLY recommend getting it done at a shop. Unless you know what you are doing you will have a puzzle of gears and springs to put back together.
Why all piston in an engine must have same weight?
You will have a smooth running engine when the rotating assembly is balanced.
How does a flushometer work?
By discharging a predetermined rate of flow and GPM using either a piston assembly or diaphragm
How do you compress the caliper piston on a 1985 Nissan truck brake assembly?
If it is the front brake use a "C" clamp to retract piston If it is the rear and the parking brake is used by this caliper piston is threaded and a special tool (not expensive) available at Sears or auto parts to "screw" piston into caliper body
What r391 dowty propeller component translates piston and shaft movement to vary propeller blade angle?
The fadec sends a signal to the pcu which in turn ports oil through a beta tube into the cylinder to either the front or backside of the piston to move the blades. The piston is connected to a crosshead assembly inside the propeller hub which slides up and down with the piston to move the blades
What is a jug on a dirt bike Honda Cr 125?
I have always heard the Jug being referred to as the Cylinder and/or piston assembly including the cylinder.
How do you change Piston Ring on a Kawasaki Bayou 220?
1. Remove the front cowling. 2. Removbe the top engine mount and exhaust pipe. 3. Remobe oil tube on the right side of head assembly. 4. remove cam tension assembly. 4. Remove cam chain cover on left upper side of head. 5. Remove cam shaft bolt, cam gear and chain assembly. 6. Remove the 4 large head bolts and 2 smaller head bolts on left side. 7. Remove head assembly. 8. Remove cylinder from block assembly. 9. Replace piston rings. 10. Reverse order of assembly. 11. Install cam chain with piston at Top dead center, cam gear notch up.
How do you replace Front Brake Pads on a 1996 Mercury Cougar XR7?
I remove the two (2) hex head bolts that hold the caliper assembly onto the brake shield assembly. The entire caliper assembly comes off the rotor and you then can remove the inner and outer pads and replace them with new ones Pop out the old pads and put the new ones in ( but remember to push in the brake piston carefully an slowly, making sure that the master cylinder cap is loosened enough to let back pressure out from compressing the piston. I use a large C-Clamp to push in the piston. You may want to use a small piece of wood between the piston head and the head of the C-Clamp, that protects the piston from scratch/gouge damage Removing the backs should be about the same except the pistons have to be pushed in by turning them clockwise by inserting a special piston compression tool (Ford Part # T87P-2588-A) and turning the piston slowly clockwise. Some use a pair of Needle Nose pliers but be careful as the sharp ends of the pliers can damage the rubber piston shroud
How do you change the rear brake pads on a 1998 Honda Accord?
The back brakes on my Honda Accord are disc brakes. After removing the brake cylinder assembly you will see the brake cylinder piston end has a slot in it. The short pin on the back side of the inner brake pad fits into this slot, but also it is used to 'Turn' (clock-wise) the piston back into the cylinder so you fit the assembly back over the new 'thicker' pads. You can not 'press' this piston back into the cylinder.
