Model T Ford Forum: Forum 2013: Timer and Fan belt conflict - no idea
Top of pagePrevious messageNext messageBottom of page Link to this message  By Michael Velling, Germany on Monday, May 06, 2013 - 03:49 pm:

Hello, now i have started my rebuild engine yesterday and it runs. But the timer rod hits the fanbelt when the lever is in a lower position (advanced). I have a andersson timer in there. What is a solution for that? Is the "eye" for the rod at the wrong position at the timer?









I have set the ignition at a little bit after TDC very correct and now this?

Kind regards

Michael

Michael,

You were not the first, and I'll bet that there will be more later.

Hard to tell from your pics but it can help if when you tension the belt you move the eccentric toward the drivers side.

Looks like your timer is set correctly---you probably need a new fan belt to allow you to set the eccentric on the fan over just a bit( more vertical) and clear the timing rod. (good info on the threads referenced, above). Paul

There are two directions you can turn the eccentric which holds the top pulley. Put a wrench on the square part in back of the eccentric and pull down on the wrench. That will move the belt away from the timer rod as you tighten the belt. Also you might be pulling the spark lever too far down when you run the engine. You should have 3 positions for the spark lever travel. One all the way up, one about 10 o clock and the other about 4 o clock of the spark lever. If you pull the lever beyond 4 o clock position using magneto, it will not advance the spark any more, so it is not necessary to pull it down any farther.

Thanks a lot for all tips. First i will try to turn the excenter in drivers direction and have a look.

@Norman: 10 o clock i understand but 4 o clock? This is at the side of the throttle lever? Do you mean 8 o clock?

Try a smaller fan belt( I know there are different sizes)

Norman, by the picture it appears Michael has the early 26 fan adjustment without the square on the rear. It is a worm screw adjustment and clamp bolt on the bottom.

It looks like the washer on the rod is rubbing the belt also. Take the washer off of the timer rod that will give more clearance.

I should have said 7:00.

The engine front cover is for a pre 26 engine and I think the timer rod was shorter for these earlier setups with a tensioner pulley. The 1926-27 timer rod's were longer I'm pretty sure.

Maybe some could say how long the 26-27 timer rod is ?

Fred

Okay I found one of my 26 timer rods. The measurements from center to center of the 90 degree ends is 13 3/8" or 34 Centimeters. Also Michael put your spacer behind the timer ear that's where it is supposed to be. This should solve your problem...Fred

Fred,
The timer rod length is controlled by how the timing is set. A person would not want to install or change the timer rod length without checking the timing.

That said in Michael's case if he set the timing when the spark lever is fully retarded at 15 ATDC rather then just after rather then "little bit after TDC" he would gain some clearance between the belt and timer.

I set my timing just past TCD and had the same problem. My solution was to use a timer that the timer rod fitting was relocated on the timer to provide more belt clearance. It works well and I believe that there are advantages to setting the timing just past TDC rather then 15 ATDC.

Jim

Yes the timing is set 15 degrees after TDC. So the position of the timer is fix. Another option is to change the rod ear at the timer to another position. Or another timer. I will have a look how the other timers i have are made.

@Steve Tomaso: In germany i eat no pizza. They are not so good and are very thick. We are going to italy and there are the original pizza. Very thin and cross.

Will place some pictures from italy pizza - smile
