TR6 Front suspension fulcrum pins


Country flag
I'm in the process of disassembling my front suspension for a complete rebuild and was surprised to see that my fulcrum pins did not have holes drilled in the threads for cotter pins. The nuts were slotted/castled however, so before disassembly I just assumed the previous owner had omitted the pins. So..are these aftermarket replacement fulcrum pins that lack the holes for cotter pins or what?

And on the subject of fulcrum pins, I was wondering about the orientation. The curved webbing faced inboard with the more flat side facing outboard. I've read differing descriptions on this and with this car, I don't take anything for granted. My car is a 1973 TR6.

Not 100% certain about the cotter pins. IIRC mine didn’t have any. The orientation you describe is correct. The more flat side faces the wheel; if it’s the other way you won’t be able to align the wheel properly.

If running car hard on track or personal curve road time, pins would not hurt. Just a safety item.

Thank you all. Both the Moss Motor catalog detail and the Bentley manual show cotter pins and in fact the Moss photo of their fulcrum pin does have a hole, but I'm with you - probably not original production. Thanks for confirmation on orientation.

My two books shows cotter pin. My guess is to lock nut without over tighten bushing. Safety first Madflyer ( I check my 1973 TR 6 and I have cotter pins there small )

When I did my 1973 I had all front end parts powder coated 27 years latter still cleans up like new. I do not show my car much any more she did her time in the ring with awards. The new guys need to get them now reward them for their work and love of LBC's. I pass the torch. Madflyer

I seem to remember (something I don't do very often any more), that at least one of the major front end rebuild kits I've helped install had nylock nuts rather than castle nuts and cotter pins. I switched the nylocks for a castle and drilled the pin. The nylock is probably adequate, but, sometimes I'm a belt and suspenders kind of guy (it's a fashion statement).
