Wonder if I could get some feed back.I have come to a halt installing a new cutless bearing to a Catalina 28 Mk 1.
The new bearing is 1 1/4 inch O/Dia with a 1 inch I/Dia -------- that is the bronze meatal tube is 1/16 inch thick.
Using best practice I lightly preheated the " P bracket " and cooled the sleeve prior to screw fitting the cutless bearing into the bracket ( threaded rod plus washers, grease between washers etc etc )
Eventually had to give up halfway into the fitting as the threaded rod had stripped it`s thread ------- yes it was that tight !! 12 inch spanner at almost limit of strength
Cut off half the four inch cutless bearing and then started to intall the two inches left over into the other end of the bracket.
Again had to give up after one inch had been inserted, with extreme force having been exerted to have got that far.
Have decided on a " time-out " ---------- it`s time for a rethink.
I`m left with half the bearing in one side, a quarter of the bearing in on the other side, and with a quarter in fresh air so to speak.
There seems to be three options.
1. Use a larger diameter threaded rod, say 3/4 inch with a less coarse thread, and just force the remaing quarter in. I am convinced that as the first half was beiing pressed in there was a distinct " bulging " of the P bracket boss as the cutless bearing tube progressively entered.This has now evened out now that the other half of the bearing has been forced into the other end of the P bracket boss. I am worried that if I continue I might just split the outer boss of the P bracket. Has this happened to anyone else ?
2. Cut off the last remaining inch sticking out and just go with three inches of cutless bearing ( two inches at one end and one inch at the other) rather the four inches as originally planned for.
3. Leave it as is with one inch sticking out. This leaves four inches of bearing material -------- five inches between ends but with one inch " in fresh air "
All responses gratefully listened to ------ sorry for the long winded explanation.
