extra parts

jsmoke · Nov 25, 2014

I took a Roosa Master DBGFC 637-52AF injection pump apart and after soaking it found these extra parts in the sink,a 1/8 " steel ball,1/8" steel rod 1 and 5/8" long and a steel piece 1/4"diameter round and 3/16" long with a 1/8" hole thru it in the center the inside looks to have an oil groove like it might be a roller. One deisel place said the 1/8" rod went in the hyd head of pump under little plug as I had suspected but neither they nor I have any clue as to where 1/8" ball or 1/4" roller is suppose to go and none of my or their photos show such parts. I looked at hundreds of online photos and none show these parts yet they came out somewhere. Please if anybody has photos or info about these i need your help

If you had all the parts rolling around in a sink
I wouldn't re-use them. These parts are highly
machined to very very close tolerances. So any
scratches they may have received while in the sink
may prove them un-useable. Injection pumps are not
to be taken apart by us that are unskilled or in a dirty
atmosphere.

I'd say you also ought to be real careful, what got lost and went down the drain?? Might pull the sink trap, check whats inside.

Depending on what style return fitting you have the ball may have come from there. It might even be from a fitting that has already been replaced but the ball remained in the pump.

As far as the little roller, might be the fuel pressure adjuster. A new one usually comes in the seal kit. The original might have been steel. The replacements are a composite material, usually tan in color.

Ball came out of the return line fitting. Pretty sure roller with a hole in it is where the spring hooks on one side.

Ball in return fitting on Roosa-Master JDB inj. pump was glass not metal but in DBG the ball may be different material.

hanks for the input I inspected return fitting after your reply and it is intact but has a ball like the one found so might have come from a previous one as this pump had more stuff built up in it than any other i have seen in many years. Looking under magnifying light at 1/8" rod found, i noticed one end has shiny smooth indentation like it might have been wearing against a ball so i really would like to find a photo showing what all goes in pump head under the plugs under the end after the the flex drive, cam ring, and rotor shaft are removed. The little roller i found before i soaked the inlet pressure regulator in the soak sink and upon examination the roller does not fit it. All pieces in governor area and fuel inlet area were coated with varnish removed only by rubbing after being soaked and this little roller was shiny without being rubbed. thanks again for your help and it may turn out that ball was from old return parts replaced before i got tractor
