Hi, Been here a few weeks but have spent the last week reading all about the brand new 2020 French Blue GTV from 1750GTV. The advice was to do a unique thread for each car so here goes....

My 1750 GTV Mk1 Chassis 1451545 was first delivered 16th Jan 1969 to Lady Miranda Guinness since having 3 further owners. My intent is not to do a 1750GTV restoration but just to do a visual tidy up for my taste. Mechanically it's absolutely sound as last owner was the premier Irish Alfa Specialist. Visually and body wise pretty good too.

I have had a problem with the passenger door closing and the lock and the door closing led to the disastrous situation of a broken window. While I'm at the door, I'm going to fit a new lock barrell and tweak the door position and generally look at how I can get it to work with a light touch.

I've taken the handle off and my first problem is now trying to address that the handle only activated the lock when it was almost fully pulled.
This could be the reason I feel in that the bolt that screws into the handle has huge clearance to the lock because it can't be screwed down. I can replace it very easily but of much greater concern is the threaded hole. It does not go straight through the lever but at a very significant angle. Is this normal to maybe get a perpendicular action on the lock?

The angle of the adjustment screw is correct (not due to a hung over machinist). Its probably angled to center the screw’s contact point on the latch. If yours is bent, it’s due to door/latch misalignment and excessive force on the handle to open the door.

Hi Ken, So the "misalignment" is as I thought. To get it perpendicular on the latch. That's good. I get what you say on the force and it was my first thoughts too but the bending is on the head side of the arm, not the latch side where the force is applied. I don't think I'll ever think of a reason why bending would occur on a part that has no force applied.

Yes. Even though the handle shows its age. It's original. Just have to find a Hex bolt now 😁.
I was lucky I bought two lock barrels from CA. The first had the diametric hole through the locking plate drilled twice, the first hole looked like the drill broke and the second hole in the same part was off centre and useless. The second barrel I ordered was missing the roll pin. Not made in USA or Europe I guess. Some Graphite in the lock and its working well now. Just need to clean up the latch and reinstall after I find the bolt.

Having found it impossible to get an M4 x 20 Hex Bolt this morning, I decided to replace the hinge pin bushes while waiting to reattach the handle and lock which have had all the dirty gunk removed and new barrels and springs added.

The bottom hinge is incredibly stiff and the top I can feel a load of rock so I'm glad I made the decision. Of course I couldn't get the pin to budge so despite all the warnings I felt I'd no option but to carefully mark the hinge and remove it to tackle the hinge pin on the bench. I'm assuming a bit of "brute force" is required. The hinge does not look straight though and I wonder if the shape is by design? Am I better leaving it or trying to straighten it and then having my carefully marked hinge position redundant.

Andrew, It’s not clear which hinge and what part of the hinge your picture is showing. What part of the hinge are you thinking is bent?

Are the hinge mounting surfaces flat and true relative to the hinge pin? Are they parallel to the opposing face or twisted?

Hi Ken, This should explain better. The door flap is sitting flat on the table top here. To me it shows the hinge pin boss sitting proud of the table. I don't have a twist. Tbh I'm happy to leave it as is. Everything was sitting square beforehand just the door wouldn't close so I'm attaching the shim to the door to move the door back away from the tightest pinch point on the seal. Along with now using the dremel as Rossano advises to split the hinge open.

Just found this??? It could be from the latch, the handle or equally from a Canon camera my son was working on.

The door half certainly looks tweaked and hinge pin side bent from forcing the door closed.
