Shorrocks oiling pin

[racetec@voicenet.com]

I am finishing the assembly of an XPAG engine fitted with a Shorrocks blower and I am in urgent need of the oiling pin and spring for the engine pressurized oiling system. I have tried to contact John Bibby in the UK but have not been able to reach him. I understand these pins were supplied in diameters of .308-.310 in half thousands increments. Can anyone tell me the details of the pin? overall length? is it stepped for the spring? what material? The same with the spring, OD, length, wire dia. and material. Any help would be appreciated. thanks, Dave E'nama Warminster, PA 18974

Dave, just for the heck of it, contact Mike O'Connor at Oconnor Classics mike@oconnorclassics.com If I were looking for that pin, he's the first guy I'd contact, even if he didn't have it (but I'd bet he does) I'd be willing to bet he'd know exactly where to get it. best of luck, sam

Note that the following only applies to the systems fed from the engine oil pressure; I don't know anything about the earlier (?) gravity / air pressure fed systems. You are correct on the outside diameters; mine runs on a "C" pin (this is stamped on the end) which is 0.309in OD which is probably a good starting point. I made up some of different diameters to see the effect but the original "C" seemed fine in the end. The length of the main body of the pin is 1.030in where it is then stepped down to 0.185in OD for a further 0.150in in length to hold the spring. The original pin is some kind of steel; not sure what; I used silver steel. The originals have fine ground finish (which I could not reproduce). I cannot give details of the spring until I take it apart again. However, as a guide, the ID of the spring gripps the peg on the end of the pin, the OD obviously fits within pin carrier so is less than 0.308in and the length, from memory, is about 3/8in. Its a fairly weak spring; I am not sure how critical the spring is since it must spend must of the time fully compressed; maybe it is just to stop the pin sticking. Hope this is of some help; let me know if you need anything more. Good luck with setting it up; its worth it once it goes properly! Regards James Mumford

James, Thank you for your response on the oiling pin, I will use your dimensions to machine a pin and search for a suitable spring. I agree that the spring pressure would seem to be fairly non critical. I have been told it was only there to assist in pushing the pin out during normal service and replacement. Thanks again, Dave E'nama
