Hi everyone we have had the babbits done on the engine and are now putting it back together we have followed the punch marks on the timing gears but it doesnt seem right , the story with the car is that the engine had been apart before we bought it so the punch marks may not be in the right place, is there any help you can give me please?
As you can see in Ray description of the location of his wonderful write up, it is in the Members Only area of the VCCA's web site. Meaning, you need to be a VCCA member to access those Technical Articles. There are many, many good reasons for joining the club. Here are a few:
Only members can use the site's search function
Get access the member roster online (to get an individual's contact info, for example)
Access technical articles
Post photos on the site
And, a bunch more.
As for your original question, I'm not familiar with the 1925 repair manual, but the '27-'28 repair manual gives a good description for determining the orientation of the cam shaft gear to the crank shaft gear. This description does not rely on the 'markings' on the gear, but gives you the procedure for figuring out the correct orientation.
Cheers, Dean
Dean 'Rustoholic' Meltz old and ugly is beautiful!
thank you we have (in theory) everything as it should be we have used the timing marks and tried it with no luck so we have tried it using tdc and setting it up but nothing seems to work, Im not a member so cant see the school session unfortunatly.

[/quote[quote=AntiqueMechanic] That is a problem that we run into occasionally. If you will follow the instructions and go to my "School is in Session" that subject is addressed.
Here's the path to find it: VCCA home page -> Members Only -> Technical Articles -> scroll down to 4 Cyl Engine Rebuild - School is in Session
Some interesting reading when you get there.
thanks ray unfortunatly im not a member at the moment so I cant see the article.
For 1925 determine the top travel of the number 1 piston after the intake valve has closed. This will be the top of the compression stroke. Remove the spark plug and put a screwdiver in the open hole to determine when the piston is at the top. Set the points so they just begin to close with the retard lever in full retard.
Attached are two pages one from a Repair Manual and the other from Service News. They relate to the cam shaft timing for 4 cylinder engines. I have helped several people correct the timing problem stemming from incorrectly marked gears. It must have been a real problem at the time to have made it necessary to put it in the Service News in 1928.
Hope this helps you and others. Too many think the problem is in their carburetor. The odd thing is that two of the people helped were in Hemet California. Go figure?
