Rod Miles Posted March 27, 2020 Share Posted March 27, 2020 Ready for the re-build of my 1928 Buick straight six standard. A clear stamp is on the crankshaft gear for lining up with the cam gear. However the cam gear's marking is not evident. Advice on properly lining these up with-out the second gear stamp for timing purposes?

Guest Posted March 27, 2020 Share Posted March 27, 2020 Any time I disassemble an engine, clutch, transmission or differential I always punch mark everything. Factory marks are great provided you know how they correspond to each other and someone has not been there before you an messed something up. After eighty, ninety or more years who knows what may have been done by someone who thought they knew better than the factory. Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted March 27, 2020 Share Posted March 27, 2020 (edited) Rod, Here is some information for you to review. Timing gear marks were quite confusing when I went thru my engine. If what you are looking for is not here, please respond back.

Rod Miles Posted March 27, 2020 Author Share Posted March 27, 2020 Thanks, Tinindian. I didn't disassemble the engine but am doing my best to get it running well for the cars' restoration. Link to comment Share on other sites More sharing options...
hidden_hunter Posted March 29, 2020 Share Posted March 29, 2020 I haven’t looked at the Buick shop manual recently, but the cad’s of the vintage has the procedure for aligning everything, though from memory its a bit of a choose your own adventure where you have to find the first component then at the end it will tell you what to do next Link to comment Share on other sites More sharing options...
Oldtech Posted April 7, 2020 Share Posted April 7, 2020 If it has the fiber timing gear the mark can be hard to find. It should be an "0" stamped by the tooth if I remember correctly. If no luck put the crank at TDC and find the spot where either 1 or 6 is just closing the exhaust and starting to open the intake. ( with the gear all the way in so the bevel is correct) Hope this helps🛠️ Link to comment Share on other sites More sharing options...
Rod Miles Posted April 8, 2020 Author Share Posted April 8, 2020 Yes it helped, Oldtech. Thanks a lot. I found the "O" stamp and it is a fiber timing gear. Cam is set in place, mains are tightened and off to oil pump and piston installation. I appreciate your assistance. Link to comment Share on other sites More sharing options...
