Briggs Flathead / Re: Briggs opposed twin pressure lube

Thanks - I figured they were different. I havent taken it apart yet, but I assume yes it has a screen/pickup in the sump. I guess I will plan on getting it welded. I assume that the material is cast aluminum?

Briggs Flathead / Briggs opposed twin pressure lube
« on: April 13, 2018, 07:53:30 pm »
Hi I just bought a 18 hp opposed twin horizontal engine with pressure lube-oil filter. Two mounting tabs were broken off the base. Does anyone know the difference between the the base or sump between a pressure and splash lube engine? If they interchange great, but if not guess I will have to get it welded.

Briggs Flathead / Briggs 40CI to 42 CI
« on: June 11, 2017, 02:15:51 pm »
Gentlemen, I am a newbie working on a Briggs Opposed Twin 40 CI engine. I am putting it into a mower, and it will be stock from a RPM perspective but was wondering what I could do to improve low RPM torque. The model number is 402437.
1. My first thought was to increase the displacement. I hear you can put a 42 CI crankshaft and rods in and they interchange? I was looking at a crankshaft number 690639 (which fits a 422437). It looks the same as my crank, but it does have an additional oil groove on the flywheel side that my crank didn't have, and it looks like it was cross drilled for oiling. Are their any issues or other parts I should replace?

2. Any other ideas to improve torque?
