GTV/Spider 916 door check strap repair.
My driver's door started to make that annoying click so a replacement was bought from E.B. spares and that came at a very good price, with stainless fasteners and really wasn't difficult to fit. Curious as to how the old one was worn I ground away and drilled one end of the pivot pin (upper on driver's door, lower on passenger's door) and it pushed out quite easily. The culprit part is a soft metal (lead alloy?) insert in the arm that flattens thus introducing play into the hinge. Once the insert was removed I used a vernier to measure the diameter of the hole in the arm and it is 8.93 mm and I found that an M6 rivnut is also 8.93 mm (length I used was 15 mm total) and was made suitable by taking a small amount off the rim to reduce its diameter, this enabled it to fit inside the recess on the lower part of the bracket. The bracket I drilled out using a new 8.9 mm HSS drill bit and after making a couple of thin rubber washers to fill the spaces between the sides of the arm and the bracket the whole lot was assembled with some white grease. As the rivnut was very slightly oversize it was pressed in using a bench vice. The rivnut was then given a slight squeeze to expand it and the job was done.
