| I believe by 1970 they Changed to a solid adjustable Bracket. You could upgrade To that. Those floating Brackets were bad news wore Out fast. Bob Haag On Mar 30, 2022, at 12:19 PM, John Grady <jkg@xxxxxxxxxxxxxxxxx> wrote:
This is factually a really bad design , bad idea they dropped soon after , —original idea was pull of belt self tensions it = no adjustment needed at factory . But it constantly bounces around with tension changes in belt or change in speed of engine . Then , the hole in steel bracket at hinge wears egg shaped at the front , this tilts the axle of pump down , you can plainly see the plane of the pulley is wrong ( put flat edge on pulley , pulley is tilted ) belt runs in at angle , can slip , but wears crazy on one side etc ( can’t have tilted pulleys on a V belt ) To attempt to stop the bouncing they put a rubber wedge in there , it get soft often gone . Whole idea is no good.
First thing I fixed on the first F I got about 1969 , essence of fix was to drill all the holes oversize in line and straight , a close fit for a long shoulder bolt acted like a controlled OD pin , then put a pipe spacer between tabs so you could clamp it solid like god wants a ps pump mounted . And what the rest of world did before and since , tighten the belt and tighten clamp . Done . No more bouncing motion there That May have been overkill ,—- just go up to larger long bolt and the pipe spacer . Like alternator is mounted , or two oversize bolts with nuts that are a good fit . You can also add a small bolt across the gap in the two piece mount by drill and tap to act as an adjuster— to be sure it can’t loosen up —-but a tight big bolt is ok too.
I Once made a little kit for this , some original members may remember it … Also made SS springs for generator brushes back then , the other aggravating problem on these cars ,the plain steel brush spring rusts , brush sticks in the holder . Instead of new generator and a dance with generator experts and 500$ , just tap back end of generator with dead blow hammer . Instant charge again . Or reach in abs move from back with screwdriver Then one day take off, clean brush holders and put in good springs . I had 100 stainless springs made can’t find the box , 50 years ago .. good repro project , both of these issues .. john Sent from my iPhone On Mar 30, 2022, at 11:47 AM, RICK AND DEBBIE CLAPHAM <rixpac@xxxxxxx> wrote:
