daveoman1966 3,762 #51 Posted March 16, 2019 Mind did not have any such 'scratch' in the block. If you are concerned about it, I'd mix a tiny bit of JB WELD and fill the scratch...CAREFULLY sand it smooth and move on. CAUTION..don't let the needle bearings drop out...mine did. Find a ratchet socket or two to hold them in place while working. ps...the is NOT a gasket or O-ring for this, although it looks like one is missing. Did you also make a LOCATOR mark before taking off the gear cap??? 2 Share this post Link to post Share on other sites
gt14rider 797 #52 Posted March 22, 2019 (edited) Does anyone know where to get the copper washers for the pump bolts, and the small orings, what dash # Edited March 22, 2019 by gt14rider Share this post Link to post Share on other sites
daveoman1966 3,762 #53 Posted March 22, 2019 (edited) You will have to buy some COPPER SEALS at NAPA or maybe Fastenal....that's what I did. buy 6 or more, just a little bit over OD then turn them down to correct OD. I put 6 of them on a 1/4" bolt ...tighten them with a nut, then put bolt in pistol grip drill to turn rapidly on a file that is clamped in my bench vise. aka...poor man's lathe. I MAY have a set of O-rings in shop...willl be back in am to advise... Edited March 22, 2019 by daveoman1966 Share this post Link to post Share on other sites
gt14rider 797 #54 Posted March 22, 2019 Thanks, I have an assortment of copper washers, with too big of o.d. didn't think of the drill to turn them down. As for the orings, went to a hydraulics shop, said I could use round orings for the pump, but if I can get the right ones I would rather. Share this post Link to post Share on other sites

gt14rider 797 #68 Posted March 28, 2019 Hay got some stuff done on the bathroom, and t ranny. Put in bearings on trunnion shaft and input shaft, installed seals skf 6757, don't seem to sit flush, if you put on oring and triangle spacer its flush, small side same, but seal has two lips, the outer one just sticks out enough, (pics) any thoughts Share this post Link to post Share on other sites
gt14rider 797 #69 Posted March 28, 2019 (edited) More pics Edited March 30, 2019 by gt14rider Wrong seals Share this post Link to post Share on other sites
pfrederi 17,879 #70 Posted March 28, 2019 Hydro gears didn't use seals they used O rings. The piston to piston used a seal WH#103461 CR 6763 which is thinner than what you have Share this post Link to post Share on other sites
gt14rider 797 #71 Posted March 29, 2019 Aldons gt14 restomod showed this seal skf 6757 So thinking I need 6763. Or ya think with oring it'll seal tight, with cam block and ser# plates Share this post Link to post Share on other sites
