Title: Dimensions for KS Bush 67-3151, See Photo, Pse?
Post by: Peter Gee on 29.08. 2019 09:32

Hi guys, will probably have to have one of these turned from cast iron.

Can someone please  give the dimensions of this bush inc the flanged end so I may instruct the turner?  Thanks

Hi PG.
You should give the bloke who's doing the machining both the K/S shaft & housing so he can measure both.
The hole in the housing often gets enlongated & if so will need to be bored round again ( oversize)
The shaft also wears & may need to be replaced.

 And while you are looking there, check the clutch actuator arm hole.

 You might want to get that bushed too.
