Newguys Sprint Conversion

[2F45T4U]

Looks good in primer

[newguy]

When i went for my alignment the tyre man pointed out to me that the tierod bushes were Stuffed.

I sort of knew this so he did my toe in so i wouldn't chew the tyres and advised me to see to it straight away.
So i went to Repco, And got their Nolathane Book out found the part i needed and ordered them.

When i got them i pulled the Struts out One was very badly worn so i replaced it with a good one for the 1850, and also put the anti roll bar off the 1850 onto the sprint as the bushes are still firm and in new condition. My sprint One was stuff rubbers were oozing out the side etc.

Now feels alot tighter and less bounce in the car it has really tightened her up alot.

So i haven't got my car in to town again as i have needed the work van at work.

What i have been doing.

Changed the Thermostat cover for one that does not leak out of the Expansion Bottle Hose Connector thing. It feel out when i pulled it apart, I am going to Tap it out and fit a new fitting.

So now im not loosing any coolant for there anymore, it was squirting all over the bonet, carbs engine etc. Big test will be tomorrow after a good long run.

Checked the plug gaps again as it is sometimes missing and spluttering etc.
They seemed to be fine so i wound the carb needles right out so its running nice and rich and the problem has gone, Sounds smoother aswell. Goes alot better also.

SO i also advanced the timing a bit and i think it come forward a bit more also.

And i also Waxed the Primer paint job to protect the underneath a bit better in our wet season we seem to be having.
Actually came up quite glossy.

Smells like cherry's aswell!!!!

[newguy]

Well i went and got my Chassis Number fitted this morning so the car is 100% legit!

Yaya

Have just Clicked over 500Miles so im guessing its time for a oil change, re torqued the head the other night
Everything was nice and firm.

Also have modified my thermostat cover to stop it from leaking.
The car seems to run 2 needles behind half now not just one.
But if you stop it comes up to half but after about 50metres it drops straight back down!

Also good without coolant spraying all over the engine and bonnet.

Will reveal to you all tonight.

Really thinking i should do a oil change and do a good long days driving

I didn't rub the wax off to well there is smudges of residue everywhere.
ahhh well atleast its protected.

Wheels and tryes look sooo good at night time under low light.

Did 120Miles to my sisters to visit my new nephew with the Gf car went well except i sprung a zaust leak where i had repaired it with some zaust repair stuff, started to smell when i had to climb a mountain (kiamis for anyone in NZ) to get there.
Went well over it though it is quite a good long climb up from our side i just sat in 4th, i was passing cars, trucks, over heating cars aswell. On the way home the climb is quite step and windy so i was just in 3rd clicking in and out of OD.
We passed alot of cars, and it was a good test for the temprature which did not get a needle off half way.

Getting the zaust fixed properly once ive fixed the oil leak. New rear end of zaust pipe with a good 2nd hand resonator with no cracks.

Should fix the last of my smells, Startd to miss fire on the way there i was about 5 Km away.
It didnt do it on the way home.

I think it maybe over fueling, was spitting and missing etc etc.
I have ATF oil in the dashpots now also.

Did a oil change before i went, hopefully i can get the oil pump out without taking the filter off.

One bold on the pump seems to be ultra tight for some unknown reason, i am going to have to remove my electric fan to jack the motor up far enough to get clearance which is a bit of a bum.

Ahhh well pics tomorrow

I might also be loosing a little bit of water somewhere.......... HMMMMMMMMMMMM

Did another trip this weekend 250 Odd Miles

Used the car all weekend, Sat in heavy traffic etc.
Never went a needle over half way in temperature.

Pretty sure the Zaust leak was more oil coming out of the Rocker cover Head Backing plate and dribbling onto to the box.

Only a couple of drips of oil after a overnight sit.

Picked up some new carb mounts off Geoff Sparks which was cool, and broke a fuel line on the way home in the dark.

I also adjusted the jets and leaned it out a bit which stopped the spitting and farting around in the 3-4000rpm range, but after 4000rpm
it would spit and hesitate a little bit. Geoff suggested it could be worn needles.

Might pull the carbs apart tonight and check.

Any things to watch while changing the carb mounts?
Whats the best way to take them off?

I see the early 1850 tachometer is fed differently to the Sprint one.

Are you using electronic ignition on a 12V system?

Regarding the coil, the wiring colours are the same for 1850 and Sprint, that is white wire with yellow trace goes from starter motor solenoid to +ve side of the coil and white/blue goes to distributor from -ve side. If you are using the Sprint tachometer (as it appears you are from your photo) the feed wire is from the -ve side of the coil (wire is white/slate). (The 1850 wiring loom won't work the Sprint tacho as the feed is from the +ve side of the coil.) This white/yellow wire gives a full 12 volts when the starter is operated as it bypasses the ballast resistor (whereas the resistor reduces voltage to 6V while engine is running).

For the 1850 wiring, the white/slate wire goes from the tacho to the ballast resistor (then the +ve side of coil), so without the 1850 tacho in place the wiring won't work. It should be possible to bypass this by connecting the white wire from the ignition switch to the white/grey wire which is then connected to the +ve side of the coil (doing so without a ballast resistor gives 12V). Now if you are using a 12V electronic ignition system then you are set. If not, this is where you need to wire in the resistor.


Hope this is helpful, Stew.

Im back here again, i changed the dash around tonight. To my good one with no cracks etc.
And wired the relay for my fan up.

In doing so i have no power at the Coil and therefore no Spark.

When i changed the 1850 Wiring i dont remember what i did.


This is how the wiring is i think.

12volt + side of the coil has a wire that i have put in that goes to my tacometer, and another cable that i do not know where it goes.

On the - side i have a cable going to the distro and another going some where else which again i do not know.

I have no voltage on either side of the coil.

Where should i have power with the key off and where should i have power with the key on.
And where is the power coming from? Im guessing the coil power must be coming straight off the Ignition switch?


I need the car tomorrow night so ill be getting up in 6 hours at 6am to check here to see if anybody has had time to explain and then hopefully fix the problem.

Cheers Guys/girls Stew


If all else fails can i just feed 12 volts to the plus side of the coil? to test everything is working?

[triple tango]

white / yellow from starter to coil pos
white / pink? ballast feed to coil pos
white / black coil neg to dizzy
white / back coil neg to tacho

early type tacho is wired in-line on neg side of coil (not pos), so coil neg goes to tacho then tacho goes to dizzy

to test ign very briefly, pull all wires off coil, fit dizzy wire to coil neg, battery to coil pos, it should run like that but dont do it for long if you have a ballast type coil.

[Jon Tilson]

Okay there could be a few issues with the older 1850 wiring...if you had the dash out you will have disturbed the multiplug connector to the ignition key and that is likely where the leecy has gone awol...
So check all the wires on the plug to the ignition key...

Also on an ealry 1850 (strombergs, coil on the inlet manifold) you have no in loom balast resistor...its seperate oblong block thing by the coil...

In all cases the tacho wiring and the feed to the dizzy conme from the minus side of the coil. The tacho feed is white and grey but will probably have faded. The other side is white and black....dunno where Roy gets yellow from but I suspect his wires have discoloured. Mine are all black and white....dirty creamy white but there you go...and come from the key switch...On later cars this is the end of a resistance wire which drops the coil voltage to 6 or so...on early ist just 12V and should go into the sqaure resistor thingie...
.
The ballast bypass feed which comes from the starter is white with a red trace..this comes via the gerabox multiplug and can get lost in this but more usually falls off at the starter...

Very late UK dollies have a funny dangly wire with a socket on it that conects to the dizzy from the coil -. My early ones the wire goes direct coil to dizzie...

Problems are that you have lost the ignition switch feed or put the tacho on the wrong side...or the ballast bypass has gone as well, which will make starting iffy even on a warm motor...

To solve this you really need a decent multimeter to find the right volts and where the breaks are...
To get you going get a 12V coil of some Jap tat scrapper and take a single wire from non fused but ignition fed side of fuse box...spare spade oblingingly provided by Mr Lucas...to the coil plus, connect the dizzy to the minus and off you go no worries...

Alright guys i figured out what i had done.
Stupid Stupid me.
I have now labled the cable i disconnected and put back in the right place.

Your right the wiring is up the poo on the 1850 to swap it to a sprint etc.

After i got it going and running for a while i heard hissing again.
Bloody oil filter has come loose again!!!!!

So im off this morning to get a new cartridge for my cartridge type and fit that for the weekend.
I have no idea how it came so loose!!!! Again i did it up so tight with my hand as i could.
And it seems to happen after a long sit in the garage.
Doesn't happen while im out driving.

Anyway Fan and fuel pump wired up separately so the fan ain't running all of the time.

So new connectors on the Coil Connections, New Filter and oil AGAIN and i should be away.


it wouldn't be such a fun thing going in the Van!

I have missed posting in here and tinkering with my car like i am.
Though i am almost swearing my head off after i have sorted the problem i feel so good Hehehe


Cheers For the help guys Triple and Jon

Much appreciated.

[newguy]

I made the trip a ok.

Found that the spin on filter was bottoming out before it sealed up tight it was only just touching. I now have the right filter.

Though when i was on the motor way the car ran hotter without the fan running.
If i turned the fan on the temperature would come down very quickly.

Going to try and direct more air through the radiator for he next trip.

Looking at how much work putting the Dellorto 48s on with the downsizing 45mm inserts for a bit of fun.

Well done ..looks really great after so much hard work .
Shame of course that it will never be a genuine sprint .Still as long as there is no attempt to pass it off as a factory original --who cares .
Good work done and in progress mate.

Yea it basically is a sprint.
There ain't anything different except the Rust Creating vinyl on a sprint thats not there.
It does have Sprint Motor, Sprint Box, Diff, Driveshaft, Dash, Seats,Petrol Tank, Number Plate, Chassis Number.
It is genuine just had a new body.


I Will pass it as a sprint if i want.
Though i call it a sprint because in my mind it is, it will out run a 1850 so its a sprint.


In other news i did a 450Km trip this weekend that really was not planned at all.
Car did not use any water or oil, went great but the misfire that started again.
And Picked up a brand new water pump that i got for $140NZ, that has a good shaft, Impeller etc.
As my jack shaft is in such great nick i do not want my worn water pump doing more damage than good.
I also picked up my new gasket so i can chew out the dollortos manifold to match the head.

Will post some pics tomorrow or so.
