Fireman049 Posted August 24, 2017 Report Share Posted August 24, 2017 Hi Camilo ~ Thank you for that. Sorry but I'm afraid that I am not conversant with that equipment. Tom. Quote Link to post Share on other sites
qim Posted August 24, 2017 Author Report Share Posted August 24, 2017 Thank you Tom But where do I point the gun to, if I can't see the timing mark in a 3A? Quote Link to post Share on other sites
Fireman049 Posted August 24, 2017 Report Share Posted August 24, 2017 Hi Camilo ~ You need to find the TDC mark on your crankshaft pulley. (This is normally a 'slot' indented on the pulley). Mark it with white paint then when you shine your timing light on it with the engine running then it will show up, then you can adjust your timing. Hope this helps ~ Tom.

qim Posted August 24, 2017 Author Report Share Posted August 24, 2017 You need to find the TDC mark on your crankshaft pulley. (This is normally a 'slot' indented on the pulley). I've seen it with the car dismantled, but can't see it now... Is it possible to see it in a 3A without taking things off? Quote Link to post Share on other sites
Fireman049 Posted August 24, 2017 Report Share Posted August 24, 2017 Hi Camilo ~ Yes it is. I did it on my 3A but I've got an electric cooling fan fitted to the front of the radiator. If you've got the original cooling fan on then it's a little difficult but not impossible. Better still ~ bring your TR over to Bangor and I'll gladly sort it out for you!! Tom.

Peter Cobbold Posted August 24, 2017 Report Share Posted August 24, 2017 Camilo, Be very careful working around the fan with the engine running. No long sleeves, no tie, they might get caught in the fan. Best not to work alone just in case.... Peter Quote Link to post Share on other sites
Fireman049 Posted August 24, 2017 Report Share Posted August 24, 2017 Peter ~ Do we really need to point out these obvious safety precautions to people? How the hell did I and others possibly survive working on our cars for all these years?? Tom. Quote Link to post Share on other sites

How the hell did I and others possibly survive working on our cars for all these years?? Tom. Tom, Its the ones that did not survive intact we should be concerned with. Camilo is new to working on engines, and plenty others reading the forum too. It might not be obvious to them. I once had fan blades detach from the hub while revving the engine stationary. One cut halfway through a tubular steel bonnet frame, the other emedded itself in the top of the radiator.. The fan is more a hazard than it looks.

How the hell did I and others possibly survive working on our cars for all these years?? Tom. Safety is not measured by the number of accidents, Tom -- it's measured by exposure to risk. You know that from your time in the fire service, I'm sure. Camilo is the first one to discuss his inexperience (or long forgotten experience) with the mechanical issues around our cars. Peter's note about high-energy rotating equipment didn't seem out of place. Quote Link to post Share on other sites

Quicksilver Posted August 24, 2017 Report Share Posted August 24, 2017 Hi Camilo, you have found "Macysgarage" see post #94 , timing mark is on picture. Marcel. Quote Link to post Share on other sites
qim Posted August 24, 2017 Author Report Share Posted August 24, 2017 Hi Don Thank you for the advice. At my age I often forget the obvious! And Tom, I do take up your offer. I am busy looking at a map to see the easiest way to get to Bangor. I take it that a few drinks are included... Now, back to the timing mark: thanks for the photo, but seeing that my car does not have wooden planks underneath like yours... I seem to have things on top that block the view. Anyway, let me have another good look to see if the mark is visible from any other angle. Camilo Quote Link to post Share on other sites
qim Posted August 24, 2017 Author Report Share Posted August 24, 2017 Marcel Let me have another look. Thanks Quote Link to post Share on other sites
Quicksilver Posted August 24, 2017 Report Share Posted August 24, 2017 (edited) this is the original setup the dot in the pulley is TDC cylinder 1 mark bot with white paint or nail polish so you can see it better with the strobe light. marcel Edited August 24, 2017 by Quicksilver Quote Link to post Share on other sites
Don H. Posted August 24, 2017 Report Share Posted August 24, 2017 Marcel Let me have another look. Thanks The drilled hole in the back flange of the pulley must be there, Camilo. How on earth would you be able to set timing without it? Get a bright flashlight and you'll easily see it. Quote Link to post Share on other sites
Paul Down Posted August 24, 2017 Report Share Posted August 24, 2017 Camilo, As Peter points out be very careful around the fan area especially using a strobe light. If you are not accustomed to Strobes they can effectively feeze the motion of moving parts so it is quite easy to stray into danger areas if you are not aware. I have witnessed some nasty accidents using strobe lights where the user became blasé and completely unaware. Not on TRs but the same principles apply. Quote Link to post Share on other sites
qim Posted August 24, 2017 Author Report Share Posted August 24, 2017 (edited) Thank you, Paul I'm back in one piece! I found the pointer and there is a white mark, although I cannot see if it is in the exact place of the hole. Anyway, now, I need to go back with the gun and assuming that I have to use the angle choice (see image above #102) do I zero it and then point it at the timing mark from a distance? Then, what? I take down the reading, which shows me the number of degrees past the TDC? Edited August 24, 2017 by qim Quote Link to post Share on other sites

RobH Posted August 24, 2017 Report Share Posted August 24, 2017 Well according to the user manual you illuminate the pulley with the strobe and use the +/- buttons to align the timing mark with the pointer and then read the advance angle from the display. Quote Link to post Share on other sites
qim Posted August 24, 2017 Author Report Share Posted August 24, 2017 (edited) according to the user manual Hi Rob I don't have a User Manual; just a simple leaflet that came with the gun and does not explain too much... I've been wondering what the rpm button is for and came to the conclusion that I am supposed to adjust the tickover to a certain rpm, but which? Or do I set the rpm in the gun to the actual tickover of the car, before I change to the angle button? Makes more sense.. Edited August 24, 2017 by qim Quote Link to post Share on other sites
RobH Posted August 24, 2017 Report Share Posted August 24, 2017 There are instructions of a sort here : http://dorsetmmoc.co.uk/wordpress/tech_articles/Accuspark_instructions.pdf You use the rpm readout to set the correct engine speed then do the advance angle measurement.
