My flywheel has no timing marks, just a 1/4 and a 2/3 mark. I want to know how the marks are to align with the piston position. It would seem that the 1/4 would be in the 12 o'clock position with Cyl no. 1 at TDC.
Is this correct?

Don't understand how you can have a flywheel with- out the UIC and a 25degree mark. Keep in mind that the flywheel can be installed on the crank at 6 different positions. Are you looking on the correct side of the flywheel? Does it appear that the old teeth have been turned off and a new ring-gear installed?

I agreed with RAY. I have not see a flywheel with- out the UIC and a 25 degree mark. This pictures show the correct position of the flywheel / crank. ![[Linked Image from img100.imageshack.us]](http://img100.imageshack.us/img100/7589/svinghjul0031vd.jpg) Arvid :)

Thanks for the response but, the early 1927 and earlier 4 cyl cars had no way to use a timing light on the flywheel, no hole in the bell housing etc. I have two flywheels that are bowtie models that have no timing or tdc marks. Also the marks that I do have are not on the face or the wheel but on the broad side.

Flywheel #344099 shows an application of Sup., U, C, N (Series K, M, R, V, X) Decypered, that means, all 4-cylinder vehicles from the introduction of the flat clutch, 1925, up to and including 1928. 361054 is the part number of the clutch housing and the application is Sup., U, C, N. (Series K, M, R, V, X). Nomenclature is: Housing with Timing Pointer. Any possibility of you posting the part number and date from your flywheel?

Probaly, no window was provided for use of a timing light because the timing light had not been invented in 1927!
if a window was provided the window could have been provided for an edcuated eyeball timing mechanizum.
How many of you are familar with the unique timing mechanizem used on the MODEL "A" F0RD engine?

Probably, no window was provided for use of a timing light because the timing light had not been invented in 1927! You may be correct about the timing light, however the cover had the view port and was equipped with the pointer. Otherwise you would have no reference for timing the engine. Those of you that were around when "School is in Session" probably remember that the relation of the flywheel to the crank was established for the purpose of alining the timing gear and the crank gear. This had absolutely nothing to do with the TIMING of the engine.

Actually the timing light had been invented. It was not the type with the triggering circuit that we think of as a timing light today. It was a bulb with a wire that lit when the points closed. If the bulb lit when the pointer was opposite the ball then it was in time. Same principal as setting the pointer on the ball (or # 1 piston at top with valves closed or other timing position) and then adjusting the points so they just begin to close.

Actually the first timing light was a candle that lighted when the attached sparkplug wire set it on fire, then there was the flash in the pan device, which only gave you one chance to observe the mark in the window. Chipper actually is old enough to have used one!

My flywheel is part no. 34100. I can't find it in my Chevrolet Parts manual dated 1947. Nor can I find the Clutch housing. Mine has Chevrolet cast into it and is part no. 34549. No hole for timing and no pointer.

I was asked for date code from the flywheel and forgot in the last two messages. The clutch housing only has one other number that the part no. and that is 14 The flywheel has two other numbers cast into it one is GL-2 and the other is B 11 7. Hope this helps.

I have several of these clutch housings with no hole or pionter. (for 26) I have not looked at my flywheels. The 26 manual says to use a screwdriver in the number one spark plug hole to find top dead center. I have been using a 28 clutch housing and flywheel with the markings. It's easier to time.

Gaby Did you know that there was a very early brass spark plug branded Gaby? These are extremely rare and even the President of the spark club in USA hasn't seen one. I can send you a photo if you wish. Chris

Hi my name is dave and i just joined this chat room. I'm still not sure on how to use it, but I have a question about a 1929 chevrolet pickup truck that I'm restoring at our body shop. Right now I'm working on the cab and starting to replace all the wood that holds the outside sheet medal on. So I'm hopping that some body can give me some answers. I would like to now if the inside of the panels are painted or are they just primer? should the wood be coverd by some decrotive style cardboard? Does the wood need to be painted? Also what kind of nails are used to hold the medal to the wood? We got the wood kit from Kc wood manufaturing in Willis Virgina. Any answers or help would be great. Tanks Dave

Dave, Welcome! You have come to the home of vintage Chevrolet experts. If you or your client are a member of the VCCA then the information is given freely. If not, some feel that it is a disservice to those that pay to support this site to give out all that technical information to those who don't contribute.
That being written, the wood was originally coated with a wood preservative. A minimum of interior trim was used. There is debate on the interior surface of the metal. There is little evidence to support the panels being painted black, more for primer and probably little to no coating also probable.
