Slave cylinder
Posted: Sat Apr 25, 2009 8:17 pm
Anyone interested in knowing how to convert a 3/4" 105E girling slave cyl. bore to a 7/8" bore s/c as used on the Lotus Cortina, etc.
Start by obtaining a 7/8" cylinder from a Cortina MK2 s/c or a simular s/c installed on other EnFo/BMC models.
Cut 1/4" off the frontal piston area then cut 3/8" off the stem.
Chamfer each end.
Bore out the 105E s/c housing to 7/8". Locate a girling kit SP2204
or find a 64673020 seal. These seals were used on 7/8" bore wheel cyl.
brake/clutch/slave cyl. Better yet is to find a rear wheel cyl. kit with qty (4) 3020 seals. Generic covers for the s/c rod are easy to find.
I've converted a few of these now and it works fine.
Cheers,
Peter
