Hi does anybody no why i dont have holes in my new shells, the ones i have taken off have a hole in centre.!

[Mark M]

Mike, this doesn't sound right. How's the oil going to get in? What bike is it, a Crusader I think?

Hi Mark yes 250 clipper i got the new shells from our hosts so would of thought theyed be correct, they not open till monday so can,t find out.

The holes are only needed if there is a little end feed in the Conrad and then you only need one hole which you can drill with care

Bugger this iPad I continually make typos on it!

The oil will get in via the crank journal. So no feed hole in the conrod no hole in the bearing.

Different shell makers have different ideas, some have holes some have a grove all round the middle some have both some have none, the holes and grooves help to spread the oil around the bearing, this was fairly inportant when using monograde oil, modern multigrade is thinner at start up and fills the bearing without slots and grooves.


The shells are fine but use a muligrade oil.

Mike, I was having a brain seizure when I wrote my first reply, your shells should be fine. Some manufacturers used shells with holes for pressure relief especially on multi cylinder engines but on the Crusader it'll be fine.

Turn off the predictive text options on your iPad and presto - at least 40% of your typos will vanish! I did this on my Playbook - predictive text drives me insane...can't think why anyone would want it...
