Firing Order 009

Just fitted new Bosch Brazilian Blue, HT leads and plugs. Sounds, runs and starts better but feels a little lacking in power. Just want to check… firing order 1432. On an 009 looking at the dizzy from the top is cylinder 1 bottom or top right? I have it bottom right.

Thanks for your help - I know this is a basic one but I just read that 009 it’s top right.

 

It depends if the distributor drive has been out in its life, firing order is the same.

 

009 is generally 90 degrees different to a SVDA. TDC will point to either #1 or #4, mine points to #1, if that helps?

As others have said 1432 is the firing order, good luck.

 

If it runs then they are almost certainly in the right order. The lack of power is probably because (a) it's an 009 and there's no vacuum advance and (b) the timing might be slightly retarded, at least at low engine speeds.

 

It wouldn't run if you had it wrong, but you might have a couple of leads crossed and be running on 2 cylinders if it's really sluggish.
As said above, unless you know the distributor drive shaft has been correctly fitted it's pointless thinking about where the leads go in terms of bottom right etc.

 

I think I remember Svda cylinder 1 is bottom right 5 o’clock and 009 was bottom left 7 o’clock. 90 degrees different. 1432 in clockwise direction

 

Isn’t tdc pointing to 1 or 3

 

As Zed said, you can’t be sure the dissy driveshaft has been fitted properly, so all a bit random.

 

On my 009 the rotor points to #1 when the engine is at TDC, pulling the dizzy, but leaving everything else unchanged and slotting in my SVDA resulted in a 90 degrees anticlockwise shift, this is all relatively fresh in my mind, only done last weekend.

My distributor drive seems 180 out to some engines I've seen, but it all works out, if you follow the firing order.

 

Yep, same for me same experiment same 009 and Svda results. One place out

But at tdc any dizzy will be either pointing at 1 or 3?

 

Could be, but as Steve and Snotts said you can't be sure the dizzy drive shaft is not 180 different to the way the factory intended. Given the 009 is 90 out to the SVDA, doesn't that make it "a bit of a lottery"?

 

Oh well, maybe. Here’s my 009 pointing to no 1 at tdc:

 

Yep, that's where my 009 points too its kinda logical whereas the SVDA isn't, in my thinking.

 

But @AndyBcountry has his one train station before at 5 pm

 

Pointing at #2, in other words?

 

It would have been with both of ours

 

On my T1 1600, the #1 with an 009 was at 5 o'clock, and when replaced with an SVDA it went anticlockwise 90' to about 2 o'clock. Well, about half past one really. Golly is that the time.

 

Not quite, the drive shaft has a lot of teeth, it could point in any direction around 360 degs and not matter. I think the hang up is back from some early distributors where an oilway needed to face a window in the case to oil the distributor. There's a huge thread on Samba about it which comes to the conclusion that the distributor will get oil whichever way the body is orientated.

Tis true that you can take a distributor apart and fit the drive dog 180 degs out though - maybe you're thinking of that?

The short answer is of course get yer engine rotated to TDC firing stroke no.1, rotate the distributor body so it looks pretty, put the cap on and stick no.1 HT lead where the rotor arm points. Where that is is irrelevant other than you might prefer the leads not to cross over each other in a bunch of knitting.

 

Ah well suppose all you can do is turn engine to tdc and establish if it’s no 1 or no3 firing. Turn until it’s definitely no1 then that’s your no 1 plug. 1432 from there clockwise
