timing TO-35

mrjrwj1 · Mar 3, 2018

I just bought a 1955 TO35 and the timing is off. I have the number one piston in compression stroke but when I look in the
bell housing inspection hole you can't see the timing marks at all due to awkward position. The steering linkage arms are in
the way. Do I need an optical bore scope to look in that hole? Help, what is secret to see timing marks so that it can be set
to six degrees BTDC?

they did not make it easy,
I use a rifle bore light to look inside the hole.
have someone else slowly turn the crankshaft bolt until your proper number comes up,

when you identify 6 degrees, take a Q tip with a little paint thinner on it to clean the mark area.
let it dry then use a tooth pick and some white paint to mark the desired degree.

after it dries, it should be much easier to see the mark as it comes around.

but you are right looking in that timing mark hole is no fun, you have to have a very good quality timing light (bright) to see your mark.

that is the way I did it and its worked for many years.

Yeah. Ain't that fun? looking int a little peep hole at an angle while standing on your head?
So align those marks to 6 degrees or what ever.
Now, what I did was to get a flat file and clamp it the front axle bolster put one end of that file about 1/4 inch from the front pulley and dab a spot of paint on the crank pulley and the end of the file.
Congratulations. Those are your new temporary timing marks.
Get your timing light, fire it up and adjust the dist so the paint marks on the file line up with the pulley paint marks.
Your not dizzy and falling over and the machine is properly timed.
If your like me, you will forget to remove the file for a few days...oops.
Don't do that. Pull it off once it is set.

My crank pulley has a notch and a corresponding mark on the block for TDC.

It sounds redneck but I time mine by sound. Its so much easier than lying down and peering in that hole.

Thanks. A great idea.
