I've got a square bush replacement bearing coming as part of the group buy... The genuine Toyota one isn't a great concept... They start wearing from day one... Obviously trying to keep costs down. I love the idea of a proper bearing replacement
IMO that square bush is the best design for the job, cheap and easy to replace too.
On my '90 model NA I simply loosened the starter (no need to remove it) to access the bolt underneath to loosen the assembly enough to pop the square bush out.
If it hasn't been done already, simply rotate it 90 degrees, grease it and put it back.
"a proper bearing replacement"You can buy an enclosed ball race that is supposed to do the job.
However I tried to fit one to my car but found it useless.
With the NA OEM bell crank assembly design, there was too much slack for it to ever work properly .
