Door Drop Glass Tr5/250


Recommended Posts

Hi All

 

I've had my car for nearly two years now and, believe it or not, have never put the hood up, or raised the door window glass (in my defence, it has been in the workshop for over 17 months though).

 

The old hood was shot so I've now fitted a new one. Once fitted, I decided to see how well the door glass "sealed" against it and therefore raised the window glass. The off side fits really well, but on the nearside there is nearly a 25mm gap. The hood is fine, but the glass just doesn't go high enough. I've got to remove the door trim to fit new, but would like to be prepared for what I might find and therefore wonder whether there is any adjustment? I've never known it on any other of my cars but just wondered. If not, I guess I will need a replacement mechanism if anyone has one please?

 

Secondly, having raised the glass, it looks as though someone (not me!!) in the past hasn't lowered the glass far enough and has either sand blasted the top of the glass, or sprayed an etch primer, which wont come off. Its very noticeable and not to the standard I like my cars finished so, just in case I ever do raise the windows at some time, I'm wondering if anyone might have a spare they would like to sell? I assume the glass for a 4, 4a or 6 would also fit??

 

Cheers all

Hi Martyn,

the 4/4A glass has a different angle on the bottom edge. It fits but is not good.

 

The 5 and 6 are the same.

 

When your window is wound down is it still proud of the door.

On the 4A if you adjust the bottom (down position) to be flush with the door then the top will be in the correct place. Not sure how TR5/6 achieve this.

Hi Roger

 

I spoke to David earlier who, as you will see, has several door glasses available. David believes he has both types, but is not certain which is which. Would you happen to know how we can tell for certain which is the correct glass please (measurements etc).

 

Kind regards

Hi Neil

 

Sorry to be vague, but I just need to know how to tell the difference between the glass for a 4/4a and a 5/6.

 

I've looked on the Moss site and both look the same, although mirror image, but must be different as the 4/4a are a lot more expensive??

 

Cheers

Hi Martyn/Neil,

the only difference between the two types is the angle of the lower edge where it sits in the regulator channel.

 

I will pop into the garage shortly and see if I can find the correct shape.

When I fitted a TR6 glass to my 4A in the 90's I had to raise the front of the glass to give clearance at the front windscreen.

the glass will fit all cars 4/4a/5/6. the winder mechanism and the steel channel that is fixed to the bottom of the glass is different between a 4&4a and the 5&6 . adjusting the stop will allow the glass to raise higher.

Sorry but the shape of the glass is different between the two as well as the mechanism.

On a 5/250 there is an adjustable stop inside the door frame, sometimes the holes do need elongating to get the correct fit.

The holes for the stop are here.

Thanks everyone.

 

I now just need to locate the correct parts!

I have a nos one in the study :o not for sale let me know what measurements you require.

Neil,

 

Is yours a TR5/250/6 door glass, or a TR4 door glass? It does not matter which it is, as long as I know which it is.

 

Could you take some measurements from each end of the bottom section where the metal strip to fit the glass onto the winder mechanism fits (I'm talking about the long straight horizontal section between the ears at each end which pint downwards when the glass is fitted)?

 

What should help significantly is to know the exact measurement from each end of this straight section to each top corner of the glass - 4 measurements in total. For completeness, could you also let me know the length of the bottom straight section, and how far each end of this straight section is from the edge of the glass, when measured in the same plane as the straight section itself.

 

With this information, and of course knowing which door glass you have measured, I should be able to establish exactly what door glasses I have.

 

If you'd like to PM this to me, I'll happily convert to a drawing which I will place on here for the benefit of all.

 

Thanks - I could do this by taking a glass out of a known door, but your measurements will be better as you know what glass you have (I do not know if the correct glass is fitted to the door) and this will then make life easier for many others too.

 

Let's do the job once, and properly!

I have a 4 glass and a 6 glass here and I will get some pictures up in a bit, there is a distinct but subtle difference between the two and you can see why they wouldnt fit correctly from one to the other, measuring may not show the difference accurately as its more to do with angles than anything else.

Thanks to everyone for your help in this, I never thought it would be so complicated!

 

David and I are trying to sort this in time for an old mate of mine to collect from him on Saturday morning en-route to Twickenham, where I will be meeting my mate to "hopefully" enjoy a good England performance, we will need it!!

 

Cheers

Right here you go some picture of the glasses, in all these pictures the one on top is a TR5/6 one (The one with the black sealing strip along the base) One underneath is a TR4 one.Interesting to see a very slight difference in length though I think you can ignore this and just shim the slides accordingly.

Stuart - any chance of reposting a nice TR5 vs TR4 window glass photo? :)

PM me your email and I will send you the set of pictures I have as they are too large for here.

Stuart.
