Have oversize Volvo pistons for my b230ft build.
23mm wrist pin size and new bushings installed in the rods.
Question.
The Green Volvo Manual i have, the dealer one, says they should be a slight thumb pressure to insert the wrist pin into the rod. Well mine go in great. but i think the machine shop might have opened up the new bushing a little to much. Also states that there should not be any noticeable play. i wouldn't say that mine is noticeable but with one person holding the piston down and one moving the rod around, we THINK we feel a slight movement, not sure. (and not the rod sliding on the pin towards the piston)
My measurements are as follows.
wrist pin=23mm
new re-sized wrist pin bushing in the rod=23.05mm (This is the biggest one)
Difference between Bushing and pin=0.05mm i didn't think this was bad?!
Machine shop says this difference is a general standard they use.
I trust the machine shop but want to also see what the turbo brick family has to say about this.
Thanks. Any positive input is gratefully appreciated.
