MGB – MGA – MG “T” Lower Control Arm Fulcrum Pin
The lower control arm pivot (or fulcrum pin) is often in bad shape…
Installing new control arm bushings involves removing the nuts and washers off the ends of the fulcrum pin.
Sometimes a simple picture tells all..
This picture shows the two ends of the same fulcrum pin.
You will need to undo the nuts and washers off the ends of the fulcrum pin to replace the control arm bushings. Often the control arm pieces need replacement too (because the outer bolt holes have worn oval).
When you go to undo the nuts on the ends of the fulcrum pin, if you aren’t careful, the threaded ends of the pin will break off…. Douse them liberally with penetrating oil first!
If you are successful in getting the nuts off and the old bushings out, it is very common for one end of the fulcrum pin to be severely rusty. One end is usually nice due to the motor oil dripping down onto it from above. (A leaky engine is good for something!).
Usually the other end is a rusted mess. There is commonly anywhere from 1/16” to 1/8” of metal “missing” from the surface due to rusting. You can just imagine what happens when the control arm bushing has to contact this area of the fulcrum pin. The rusted surface of the pin will tear away at the bushing, quickly ruining it. The only real solution is to install a new fulcrum pin.
Fulcrum pins used to be crazy money. In years past they were well over $100 eachand you often need 2 of them.
We just got a new supply of them shipped in from England and they are on sale now…
Fits any MGB, MGA, or MG “T”.
Two needed per car.
