Marcos Maniacs

Hi Marcos Maniacs,
I just got back from a British car meet in San Juan Bautista, 
California.  We had 3 Marcos cars in attendance.  Mark Petrinovich 
from San Francisco, Don Lattimer from Willits and I had my car from 
Los Altos, California.  Don and I arrived on Saturday to take part in 
the car tour.  Mark arrived on Sunday in time for the car show. 
Since we had three cars the organizers decided we were a "seperate 
class" and awarded Don a trophy for 1st place. The weather was 
wonderful and we all had a great time.  I have posted some pictures of 
the event for your enjoyment.

Thanks for posting the pics Mike.
Looks like you guys had a blast! 
I still can't believe that you actually got THREE Marcos (Marcii?) in
one place!
 
Also, congrats to Don for his 1st place!

Hi All,
I finally got my replacement wiper motor in this weekend, but am not
sure that it is quite right.
It moves fairly slow and almost grinds to a halt on a dry windshield,
and the "high" speed is even worse and can barely move.
It acts OK with the wiper arms off or on a wet windshield, but I still
wonder if it is right.
I used a replacement motor that was sent to me. It looked the same, but
the origin of the motor is unknown. The only real difference I did
notice is that the main gear in the original has 120 degrees stamped on
it and the replacement had 105 degrees. At first I though this was a
position marker for the gears, however the more I think about it, I am
lead to believe that the number indicates the arc that the wipers will
follow.
Now, if this is the case, would the 120degree gears have more torque and
cover more of the windshield than the 105?
Or, could it actually be a weaker motor even though that part looked
exactly the same?
I am leaning towards changing the gears because I wouldn't think that
they (Lucas) would radically change a 14W motor for each application.
 
Can anyone add their opinion/ knowledge/ experience?
 
I'd really like some second opinions before I go ripping the whole lot
back out to change the gears.
 
Thanks,
Jeff Caraway

Jeff,

I have been looking for the correct wiper motor for my car also.  I 
broke the park sensor mounting tab which means I have to manually 
turn the switch off at the correct time.  That is they will not go to 
rest position when you switch them off.  No big deal, I can do that.  
I have found listings for a Sprite wiper motor but that moror is 
physically smaller than the one in my car.  I think it being smaller 
would mean less drive power also.  I have not tried one of those 
motors, even though I have several of them.  The 120 degrees is the 
actual sweep arc of the wipers and 120 is what is in my car.  The 
actual sweep drive gear is bout 3.5 to 4 inches in diameter.  Is that 
what you have now?

Come to think of it, I didn't see one of those on this motor either. If
there is a park sensor on it, it isn't working because I also have to
turn off the switch at just the right time as well.

Thanks for clearing that up! The gearing in there right now is the 105
and that's why I'm concerned.
Not only is the arc not quite enough to completely cover the windshield,
I think that the 105 is possibly the cause of my problem.

Another point about British wiper systems is that the leadscrew that 
drives them usually only runs against half of the gear on the wiper 
post.  Over the years the gear teeth can become worn and sloppy.  It 
is possible to position the drive gear in each wiper post to use the 
other half/side, which should be in excellent condition provided the 
wiper lead screw cable and wiper motor have not been removed and 
reinsalled by a previous owner.  Remove the wipers from the 
windscreen then from inside the dash remove the two screws that hold 
the rear plate on the wiper post.  You should be able to pull the 
leadscrew cable and cable tubes out enough to spin the wiper posts 
180 degrees then reassemble.  Its worth a try?

My experience with the Sprite/Midget wiper systems has taught me that 
they are not worth the junk they are made from.  They, IMHO are to 
small and not built heavy enough.  The average wiper on a Sprite is 7 
inches long and are very light, and about a 90 degree arc.  The 
Marcos has a longer leadscrew, and larger/heavier wiper blades and 
arms along with a heavier tension spring to hold the wipers against 
the windscreen.  I think I will stick witht the manual system of 
shutting off the wipers until I can identify and locate the proper 
degree wheel for the motor in my car.  When I go to British car shows 
I always look at the wiper motors in the various cars and to date 
have not seen the type of motor used in my car.  The closest I saw so 
far was in a Jag 12 cylinder sedan Series 3.

Hi all, 

sorry I didn't respond sooner. Changing jobs - long story.

Anyway, the pre-73 V6 cars had a CORTINA Mk2 GT axle (or ocassionally 
as Salisbury diff one). Many of the post-80s cars had a Capri axle 
which, as someone else mentioned, should be shortened to fit within 
the standard V6 coupe shell (that's why Mantulas have slightly flared 
rear arches), but often people skimped and the wheels will sit 
slightly proud of the rear arches when viewed in plan.

The problem is that even some early cars have been retrofitted with 
Capri axles, as they are easier to find. Bottom line really is that 
you'll need to find out what the axle in YOUR car is NOW. Somewhere 
they'll be a part number which you can match against Ford UK 
catalogues.

On the issue of bump steer and handling kits, I've no experience of 
these although they sound good and I know a number of people have 
devised their own bump-steer solutions. 

Cheers,

Mark

Mark or anyone,

The # on my rear axle is FoMoCo # 105E 4025B.  On the opposite side 
(left hand side) are the numbers N12 and OE27.  All 3 numbers are 
cast in the housing.  I can't seem to find the Ford UK catalogues on 
the internet.  Does anyone have access to them??  If so, what rear 
end do I have??

Hi Don,
I don't know for sure but I bet that the British Ford people used 
the same rear end casting for all the ratios. (actually there are 
several castings that are slightly different on the outside made 
apparently for slightly different applications but with no relation 
to the ratio inside that fit the Cortina rear ends.  Why don't you 
jack up one of the rear wheels, put the car in neutral, rotate the 
wheel in the air 1 full turn and count how many times your 
driveshaft/pinion flange goes around.  The available ratios are far 
enough apart that you should be able to tell which ratio you have. 
Dave Bean Engineering list the following ratios that would be 
candidates for your car... 3.55 (3 and 1/2 turns of the pinion), 
3.77(3 and 3/4 turns of the pinion), 3.90 (almost 4 turns of the 
pinion) Of course, you could always pull the rear end apart if you 
are really courious ;)

Hi All,
Just thought I'd give everyone an update on my wiper mess.
I spent a LOT of time this weekend, but it is finally fixed!
I ended up taking out the entire wiper mechanism to get it to work
though.
It seems that the tubes the leadscrew runs through were a bit bent. The
middle one was tight enough as it is, so the bends didn't help much.
After some straightening and much greasing (of everything involved!),
they seem to be working like a charm now.
BTW, the 120 degree gear is very important, as the wipers now cover the
correct amount of windshield and the automatic wiper park works.
 
So, for the record I now know that Marcos wiper systems contain:
Lucas 14W motor (motor internals are the same no matter application)
A 120 degree gear (special for Marcos-don't know of any other
applications at this time).
 
I also became very intimate with my dash, dash wiring, switches, gages,
and other odd bits I accidentally broke along the way!
Anyway, I was able to get her on the road a little, and I must say.
Marcos are not like anything else I've ever driven!
 
Now. on to the reverse lights..
 
Happy Marcosing,
Jeff Caraway
#8052 1984 V6 GT (now with working wipers!)
