Attempting to rebuild a roller vane PS pump off a 1964 4 cylinder 4000. On the pump body there is a pin called the cam retaining pin #25 in diagram pic.. my IT manual shows it, but the NH/ford web manual does not (see pics.) anyhow mine is on its last leg See pic. just a little nub sticking out. any ideas on how to remove it and anybody know a size for it . I 'm thinking either to drill it and a small easy out or heat it and try pulling it out or am I SOL any ideas or input will be appreciated. 2) in the last pic there is a tube in the reservoir inlet hole. is that suppose to be like that or is it part of the reservoir and came off.

Thanks for the reply. I'm sure it is a pin of some type but don't think its the typical roll pin as the center is solid as far as I can tell. pin dimension would help but I can probably figure it out by measuring depth of hole in body after I get it out and measuring depth on cam ring. wouldn't happen to know a part # for a seal kit? Had another thought on removal. Drill and tap with a 2-56 tap put a screw in it and see if it will pull out. Again thanks for the reply
 
I think the pin is an alignment pin that is meant to keep a part in a particular location and is likely to be extremely hard. It is unlikely to be worn, you won't be able to drill it out as it is harder than most drills.
 
It a pin that keep the cam ring from turning.Take it out like you said and make one, nothing special.
 
Thanks for the additional comments. The pin is soft as I was able to drill it and tap it. now just a matter of getting it out.
 
That pin is shown in the parts drawing for the HD Industrial version of the p/s pump for the 4 cylinder 4000. It's labelled #12 in the drawing. Part number is 370903S, but it says "No Longer Serviced".
