ArticiferTom Posted December 17, 2021 Share Posted December 17, 2021 Asking for my cousin who is starting restore . Want's to know if camshaft gear to drive oil pump is replaceable . The best way to remove it ? And where to get if available . This is on 1913 Mod 22 4cylinder . Have parts diagram . Or call me at 570 401 five eight 68 .

Luv2Wrench Posted December 18, 2021 Share Posted December 18, 2021 (edited) The shaft is in two parts and is easily separated. The bottom half of the shaft is part of the pump. The top half can only be removed (at least on mine) by removing the camshaft and then removing the casting that holds the shaft/gear. I assume that once removed you'll be able to either press the gear off the shaft or a pin/screw will be visible. I would imagine the gear would be a standard bevel gear and you could buy one or make one. Note that it appears to all be one piece but the crankcase top is cast aluminum and the casting that hold the shaft/gear is iron. A simple magnet test will confirm.

ArticiferTom Posted December 18, 2021 Author Share Posted December 18, 2021 Great pic of it disassembled . The part I am referring as bad is not this one pictured but the one on the cam that drives this one . No removal of cam has been started , yet .

Luv2Wrench Posted December 18, 2021 Share Posted December 18, 2021 OK, that's good news for you guys, just removing the camshaft is all that is needed. The gear slides onto the camshaft and is keyed. I don't have that part handy right now but I have a picture I took about 10 years ago that (sorta) shows the gear. Link to comment Share on other sites More sharing options...

Are those babbit bearing by it ? And Does anyone have a gear ? It does come out the front and I believe they are babbit but I don't have them close by to check. I would think that you'd be able to find a bevel gear to replace it. In theory I have 2 since I have 2 engines but I wouldn't want to part with the gear as that leaves one of the engines missing a key part. If you don't find a gear let me know. I might have what is needed to cut one, however time is a big concern for me right now and I doubt I could get to it any time soon. 1 Link to comment Share on other sites More sharing options...
ArticiferTom Posted December 19, 2021 Author Share Posted December 19, 2021 I have forwarded pics to cousin , thanks . We may ask for some measurements if we need to recreate, in future . You and other have been a big help . 1 Link to comment Share on other sites More sharing options...
Luv2Wrench Posted December 20, 2021 Share Posted December 20, 2021 I did find the gear and it is: 26 teeth 0.75" ID 1.50" OD A quick search at the usual places found absolutely nothing. You'll probably need to get one made. 1 Link to comment Share on other sites More sharing options...
WCMetz Posted December 29, 2021 Share Posted December 29, 2021 I dug around in my spare parts today and found a spare camshaft with the gear on it. I will dig some more as I think I may have just the gear also. I will sell the gear and camshaft as one if I don't find the gear I think I may have. Removal from the camshaft would be up to the new owner. Please let me know if you are interested. Enjoy, Bill Metz 1 1 Link to comment Share on other sites More sharing options...

Luv2Wrench Posted February 28, 2022 Share Posted February 28, 2022 why are there holes in that gear? It has been ages since I've seen my gear but I don't think it had holes in it. Link to comment Share on other sites More sharing options...
ArticiferTom Posted February 28, 2022 Author Share Posted February 28, 2022 That is where fiber ring gear is riveted to this side of cam drive gear . This setup has phenolic on both sides . We have gear at machine shop now , they think can water-jet some replacements . Fingers crossed . Anyone out there has extra 1912 reversible wheel hub or whole ,Let me know . One unit is sized in damaged out of round . Link to comment Share on other sites More sharing options...
Luv2Wrench Posted February 28, 2022 Share Posted February 28, 2022 OK, I need to take another look at mine. I might have a reversible hub, I'll check tonight. Link to comment Share on other sites More sharing options...
