Halfshaft Nuts:[ 2 submissions ]
The threads cut in the nut are just too small and will not fit the half shaft. It may be that they are plated after machining. I have tried them on a lot of shafts so its not the thread on the shaft. The problem is not with just one nut.
Brake Cam Shafts:
The slot machined in the shaft for the brake lever is not in the right place and makes the lever point forward too much, i.e. about 20-30 degrees not 10-15 degrees.
Brake Cam Shafts:[ 3 submissions ]
There is no rounded edge on the flats of the actuator so it cuts grooves in the shoe foot after little use.
2 previous comments that faces are not rounded causing grooving in the steel shims. An AMCo drawing for the Girling brakes clearly shows radii, unfortunately the Archive has no drawing for the pre 1936 but Pitman drawing might suggest radii. Austin 10 cams were certainly rounded. Stanley Edge's original pocket sketchbook for around 1922 shows rounded cams. I have filed radii on my cams (use a chainsaw file as there are no edge cut faces) and there is no loss of braking as the eventual full diameter is still reached. Note that new steel shims for the 1926-36 shoes have been available in sets from Don Breakspear for several years-see Red Cross Directory.
Brake Cable Ends:
The end that is bolted over the ball has a slot in it to accommodate the neck of the lever ball. It is tapered to a point so it cuts into the ball neck. the originals were rounded. it is necessary to grind this before fitting.
Rear Wheel Bearing Retaining Nut:
Carrying on from the half shaft nut problem, I can add the fact that several new nuts as above were impossible to fit, even after a bit of fettling. The original nuts screwed on by hand no problem. Not sure of the reason, but maybe plating or just poor manufacture? (please note that the threads on the axle were fine although I carefully cleaned them with a thread file just in case).
Fabric Coupling (Propshaft):[ 2 submissions ]
P.C.D. of holes in the coupling incorrect. Two would fit over the studs but the third would have to be forced over the stud to fit (both gearbox spider and propshaft spider), thereby putting undue pressure on this stud with the result that the propshaft was out of balance. Required over an hour to fettle to make a good and easy fit.
Front Brake Rope Swivel:
Replacement swivel of poor casting quality, with brake rope fitting on one side of the swivel only (between flanges). Opposite side had to be filed out to ensure a correct/clean fit of the brake rope.
Front Shock Asborber Spring Plate:
Replacement spring plate is really not fit for purpose. Spring plate (spider washer) can be virtually flattened against the shock absorber arm/friction discs without providing sufficient force to provide efficient operation of the shock absorber/friction discs. The 6 arms of the replacement spring plate are not of the correct form which combined with the depth of the plate (effective force) being only 0.375" against the 0.5" of the original plate.
