rob7 Posted April 22, 2019 Report Share Posted April 22, 2019 Hi it’s me again now to sort out the trigger wheel where I can get one also has anyone who has fitted one got any pictures Rob Quote Link to post Share on other sites
marki Posted April 22, 2019 Report Share Posted April 22, 2019 Hi Rob. Hope this is useful, trigger wheel was from Emerald. Had it fitted to the rear of the damper by a local engineering firm. cheers Mark. Quote Link to post Share on other sites
harrytr5 Posted April 23, 2019 Report Share Posted April 23, 2019 I machined mine like that Mark, then put a step in it, as I was concerned that the magnetic sensor would pick up the damper being the same level as the trigger wheel. EFI is great. Regards Harry TR5 Nutter Quote Link to post Share on other sites
rob7 Posted April 23, 2019 Author Report Share Posted April 23, 2019 Hi Mark thanks good picture been on emerald site will find out what size I need and order one thanks again for your help Rob Quote Link to post Share on other sites
marki Posted April 24, 2019 Report Share Posted April 24, 2019 Pleasure Rob. You won't regret it. Quote Link to post Share on other sites
rob7 Posted May 6, 2019 Author Report Share Posted May 6, 2019 Hi again got a trigger wheel put it on the back of the damper but it catches timing case how do I get over this problem thanks Rob Quote Link to post Share on other sites
iani Posted May 6, 2019 Report Share Posted May 6, 2019 I had material removed from the pulley and the wheel let in, no change in width that way. Quote Link to post Share on other sites
TriumphV8 Posted May 6, 2019 Report Share Posted May 6, 2019 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. Quote Link to post Share on other sites

I used the same wheel Andeas, I then had my pulley balanced after it was fitted. Quote Link to post Share on other sites
TriumphV8 Posted May 7, 2019 Report Share Posted May 7, 2019 Yes, pretty much the same except mine has three bolts, yours six.... Must be the correct solution. :-) Quote Link to post Share on other sites

InfinityJon Posted March 25, 2023 Report Share Posted March 25, 2023 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?

BlueTR3A-5EKT Posted March 25, 2023 Report Share Posted March 25, 2023 (edited) 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.

john.r.davies Posted March 25, 2023 Report Share Posted March 25, 2023 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! John Quote Link to post Share on other sites
PodOne Posted March 25, 2023 Report Share Posted March 25, 2023 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? Andy Quote Link to post Share on other sites

One crank and one cam and get the software to work out the mean? Edited March 25, 2023 by BlueTR3A-5EKT Quote Link to post Share on other sites
InfinityJon Posted March 25, 2023 Report Share Posted March 25, 2023 Great input but any chance of seeing the Hall effect sensor mounting as requested? Quote Link to post Share on other sites
BlueTR3A-5EKT Posted March 25, 2023 Report Share Posted March 25, 2023 Sorry! Quote Link to post Share on other sites
john.r.davies Posted March 26, 2023 Report Share Posted March 26, 2023 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. John Quote Link to post Share on other sites
