WLA Indian cases

Post by steve » Fri Feb 19, 2010 3:29 pm

On Indian and WLA cases there is a web in which the con rod passes through just below the barrel. What is the purpose of this web and what are the negatives if it is partially or fully not there?
I have heard conflicting reasons for its use. One is an oil scraper to keep oil in the crankcase away from the bores. The second is to keep oil up the top of the motor to lubricate the bores and the little end. They can't both be right.
The second question is why don't new engines have this feature?

Thanks

Oil sits on the web and splashes onto the skirts and rod. Modern engines don't have then as the oiling systems are better now.

Neo
If I have a set of cases without these webs or I remove them to reduce pumping loses can I modify an old oiling system to overcome the need for the webs? If so what do I need to do?

Dunno if it's a big deal. I'll find out though.
