I have succesfully repaired (striped rack) the right hand window winder and is now in full use. I then went to do the same to the passenger winder and all seemed well until it was all fitted back in and then I found that you could push the window down with your hands, not easily but you can. Can't at the moment find out why and have the window jammed up with a piece of wood until I get more time to work on it. Any experiences of this would be a help in working out what is wrong. Cheers Colin

Its the spring tension that needs increasing

You have probably got the spring position incorrect? (wrong way around?), when the winder cog box and the first tooth of the quadrant meet to start winding the spring should be under tension and this continues to tension as you wind up the window.

Inside the mechanism on the opposite end of the shaft to the square section is a coiled spring. Until the handle moves and winds up the spring it is contact with a circular housing and the friction holds the window so it cannot be pushed down. These springs can break. As you turn the handle you should feel a bit of slack before the spring is engaged. I have an old unit dismantled somewhere I will take a picture if I can find it.

I have done the two front winders and it's only the passenger side that you can push down by hand. I actually repaired the rack on the driver's side with welding and filing and then after I got it back together realised that it doesn't have to be repaired but have the rack turned end for end and re-secured with a new screw fitting. A couple of pictures. First is Driver's side damage, 2nd is the repair to rack by turning it around and re-fixing with drilled and tapped screwing and the third is the passenger side which was not bad and only had to clean it up and grease. Still confused about the "looseness" of the windows though. Car is in use at the moment but will have another look later after I get the Cossie back on the road. Cheers Colin

Colin, I repaired my window also and did the following things At pos4 i welded in a small bush as the original "bearing" surface is very small. I had several winder mechanism and found that some rear door winders had a cupper bush fitted The shaft in pos2 was pretty worn so i welded that up and asked a friend woth a lath to machine it to the correct diameter again On some of the mechanism the shaft near pos1 came loose from the bracket so i put a small weld there. After the welding, i cleaned it and got it zinc coated. some of the looseness could also be caused by worn teeth. I had winder mechanism from both LHD and RHD cars so picked the mechanism from the passenger side from both cars as these are less worn as the driver side. Regards Peter

You can see that Peter has taken out the three rivets that secure the housing,the spring I refer to is inside that. It acts as a sort of brake,I found that when the mechanism is getting a bit tired that oil getting inside the housing can reduce friction enough that the window can be pushed down with the flat of he hand from outside the car.

Ahhh, I didn't strip that bit down but what you say above is probably the cause of the "loose" window. I will reconsider the situation after I start on the Rover again. Thanks for the pointer. The problem with having a 40 year old car is not having electric windows !! Ah well Can't say it's any more inconvenient than that though as I am finding the car a good every day runner, as I did my first one - a 3lt Cheers Colin
