Hi,what should the gap be on the disys points,is the A14 & A15 the same.What should
the dwel angel be on a A15,and the timing.Could anyone please help me?

Thanks CCG

Contact breaker point gap 0.45-0.55 mm
Distributor dwell angle .49-55 deg
Ignition timing at idle speed 7 deg btdc in neutral

That's the same for A14 & A15

Will there be any catastrophic effects if your dwell angle is 58 degrees? or am I just a tad paranoid?

Nah....it's only how long the electrical connection is made between the spark plug and the coil - 1 degree is nothing. I was trying to start my car with the timing 180 out....fire in the intake rather than the exhaust...that was a little bad.

Timing I'd say is worse to get wrong than dwell.

thanks.

LOL, I've done almost the same thing. rotated the sparkplug leads one point to the left or right(my memory sucks at this time of the morning) and got a new understanding why pre-ignition is also called ping. Made the same sound as a submarine hehe. Luckely no engines were damgaged in the making of the sound.

Quote:If you use a dwell angle meter [prefered] then set the points to 49 degrees. As the rubbing block on the cam wears, the dwell will move through the range towards 55 degrees & your timing will slowly retard a little.
If you start at 55 degrees, you are already at the wrong end of the scale & it will quickly go out of spec.

I reset mine last night & it came out at 48 degrees. Close enough,....... but always recheck the timing whenever you adjust or replace the points.

Thanx for the information! Im in SA,and the people at Nissan tels me,that the old nissan sentra box shape disy fits in my A15 with out any mods,its a electronic one. Im not sure,what should the intake and out specs be of the valve clearence? The DAt now have a 5speed box and a A12 dif with the A15.

Valve clearance (hot):
Inlet 0.35 mm
Exhaust 0.35 mrn

Cold set to .25mm

Here's some other stuff you might ask for...

Spark plug type:
N.G.K. . . . . . . . . . . BPSES, BP4E, BP6ES, BP7ES
....... Hitachi L46PW, L47PW, L45PW, L44PW
........................ Spark plug gap 0.8-0.9 mm
. . . . . . . . . . . . . . . . . Spark plug tightening torque 20 Nm
............ Contact breaker point gap 0.45-0.55 mm

Engine idle speed:
.................. Manual transmission 650 rpm
................ Automatic transmission 750 rpm
.......... *Compression pressure (nominal) 1245 kPa
........... Compression pressure (minimum) 980 kPa

Fan belt deflection 8-12 mrn

Enjoy - jealous of the 5 speed too - a little rare in Australia.

Thank You 4 the information!its useful to me.Set the timing,and dwel and hopefuly the points wil last a bit longer.I have a A14 Nissan ute jear 2005 Mod.The people here in SA say that the A14 Nissan ute is going of the market,they not going to make it any more?There is plenty of spares for A12 A14 here in SA,as the A14 Nissan is the same as A12 Datsun.Maybe you must try and inport a 5speed box?

Your welcome.

All the info came from a Datsun Sunny workshop manual - you could pick up one one ebay - or download this one that I have text recognised as well.
