Fitting a new 025905205af distributor - rotor arm alignment?

Post by bikerbriggsy »

Hi Chaps,

Maybe an easy one for you guys due to my newbiness & lack of experience, I've seen some hits online about ftting new bosch distributors being aligned to piston no #2 ? as opposed to my old one to no #1 ?
and wondered what to do in this case?

My 1987 2.1 petrol with the DJ engine code (This engine was taken from a 1990 model) was previously converted from a 1.9 petrol after it blew up years ago -

Last night I swapped the new distributor into the old ones position (which had a very badly warn rotor arm & has 2 vacuum connectors but only 1 is connected to the carb) & once the new distributors drive peg engaged into the recess (in the right orientation, leaving the car in gear!) ... when I pushed on the rotor arm I noticed it is pointing to a different position as compared to the old one (from the photo I took of my old distributor) ... is that because the new distrib is aligned to piston #2 ?!?

What do I now need to do?, before even attempting to fire the engine up - from the haynes manual it says remove plug #1 & turn the engine until you feel compression in piston#1 and re-align to the pulley marker (outer U notch?); do I need to do the same BUT for piston #2 !?! ... I didn't forsee it being that much hassle in line with JK's comments just plug + go (expecting it to align in exactly the same posn) when I purchased it :( :(

Is it worth me leaving this to my local garage since I haven't got a strobe do you reckon?
I can always re-fit the old one.... btw I haven't snipped the existing ignition connector wires (semi-circular ended plug) and changed these to the junior power timer plugs (rectangular plug) yet! ...

Any advice appreciated!
Thanks
Rich.

PS I paid £149.95 for it from JK (got this discounted by 10%) for the distributor; 025905205af for the 2.1 petrol DJ model (which is now out of stock on JK's website)

... but looking on ebay this one fits the bill for half the price and appears to have the correct (original) connector ...

Oh well which one shall it be, or shall I return it to JK and say it's the wrong one?!?

See the difference in alignment between the new and original...

Could it potentially require a distributor for the original 1.9 engine as identified in the ebay item (especially if ignition coil is the original?!?) am stuck!
I will call Just Kampers in the morning to see what they say!

Morning,
You are not getting many replies here are you?
I can only say what I have experienced, which is JK stuff hardly ever fits a t25 .
I run a DJ engine with a carb, and I used the original DJ distributor Just using the advance , With the retard port blanked off .
You really need to speak to someone who understands the advance retard curves .
Personally I would return that to jk, and speak to brickwerks .

Thanks for the advice Steve, will do...

Just order the correct one from these guys - very good and they confirmed it was out of alignment on the phone...

And it fits, the seals the correct type also (regtangular cross section as opposed to circular) .. just had to tap home with a bit of soft wood + hammer and its alignment is spot on - sorry JK you must have sent me the wrong item!
