Trigger wheel


Recommended Posts

I had material removed from the pulley and the wheel let in, no change in width that way.

Balancing the pulley shows the step for the trigger wheel.

Mine is from  http://trigger-wheels.com/store/contents/en-uk/p5.html

Wheel is opened up on the lathe to meet the step on the pulley.

I used the same wheel Andeas, I then had my pulley balanced after it was fitted.

Yes, pretty much the same except mine has three bolts, yours six....

Must be the correct solution. :-)

 

Anything to push the bill up I imagine :-)

Morning,

 

I'm putting a megajolt on my 76 TR6.

Going to machine the crank pulley as below.  Where is the sensor mounted for this setup and does anyone have any pictures of the sensor mounting for the missing tooth in this position please?

 

Thanks

 

Jonathan

Is there not an issue in years to come if the rubber bonding between the hub and pulley flange deteriorates that timing scatter may occur?     I would have thought fitting direct to the hub would be error proof way to ensure the trigger wheel remained timed to the crank.

Very much agree, BlueTR3!   And although removing material and then adding the trigger wheel may be not add up to a great difference in the mass of the trigger wheel, it won't be the same as when it left the factory.  The change in resonance could affect torsion vibration damping. 

Attach a trigger wheel to the hub!

Suspect there will still be some scatter as the timing chain wears even if the damper remains sound. A cam sensor would help but how to fit it would be problematic?

Down the hole where the distributor used to go?

 

Would you have two pickups.  One crank and one cam and get the software to work out the mean?

There's an episode of Project Binkie where they modified the distributor to have a Hall Effect sensor, for just the above purpose.  Can't remember which, it's in one of the engine episodes, but you would find searching fun.
