Hello:
I am in the process of rebuilding an Emglo K pump, and need to replace one of the two pistons; I purchased the piston (pt # 150-1150) and the connecting rod (610-1441) and piston pin (150-1005).

I notice that the when assembling the piston, pin and rod the pin slides smoothly through the piston and the rod. I thought I was going to have to "press" the pin into place. I did not see any kind of clip that will keep the pin in place.

Am I missing something?

Thanks,
Duncan

Yes, I have those... thank you.

One more question: When installing the connecting rods am I correct in assuming that the "2 dots" on the rod cap and the rod should be on the same side, and they should point to the front when installed?

Thank you, this is helpful

Another question:

The piston rings don't seem to have any sort if identifying marks to indicate which side is the top. (no dots). Can you clarify how to properly install the rings?

The oiler rings (located at the bottom of the piston) I understand

The scraper ring (located in the middle) has a groove around the outside with a bevel on inside... does the grove face up or down?

The compression ring (located at the top, near the face of the piston) has not grooves or bevels; but the ends have a "stepped" edge that seems to interlock (creating a slight gap). It doesn't look like it matters which direction this ring is installed.

Any help would be appreciated.
Thanks
