When fitting semi-floating piston pins, it's essential to ensure proper alignment and clearance between the pin and the piston as well as the connecting rod. The pin typically fits tightly in the piston but is allowed to slide within the connecting rod, facilitating rotation and reducing wear. Care should be taken to maintain the correct tolerances to prevent excessive play or binding, which can lead to engine inefficiencies or damage. Proper lubrication during assembly is also crucial for optimal performance.
Yep!
Yes, wrist pins can cause knocking problems in an engine. If the wrist pins are worn or damaged, they may allow excessive movement of the piston, leading to improper alignment and increased clearance between the piston and cylinder walls. This can create a knocking sound, often referred to as piston slap, especially at lower RPMs. Additionally, if the wrist pins are not properly lubricated, it can exacerbate wear and knocking issues.

You need a special brake piston tool to do this. Here is a link that shows what this tool looks like: http://www.lislecorp.com/tool_detail.cfm?detail=416 Basically, you put this on the end of a 3/8 inch drive, then use the side of the tool where the pins match your brake piston. Engage the pins from the tools into the piston slots, press in and turn clockwise. It will take a lot of turns to move it back in the bore.
can you tell me if rear caliper piston screws in
There are three types of piston pins they are, Stationary pin Semi floating pin Full floating pin
Remove the two pins going through the pads. Pull out the old pads, push in the piston and install new pads, replace pins with the clips.
If you have all the parts out and clean. I have see it done. Freeze your wrist pins. heat your piston rod. Assemble quickly. This is the only way I know how with out a press.

To keep the rings from rotating on 2 stroke engines. You will not see this on 4 stroke engines.
The number of pins at the bottom of the stick. Some ddr's have 184 pins, some newer models have 240, starting with DDR2.
Calipers do not have a grease fitting. The only fitting is a bleed value and this is for brake fluid to come out of when you bleed the brakes. I bet you are trying to lube the caliper pins. Simply remove the pins holding the caliper on and use the appropate brake lube. You can pick up the correct lube at you local parts store
