I build racing engines for a living, and perhaps went a step further than was necessary. Regardless of any hearsay, the dyno speaks truth. Archie /////////////////////////////////////////////////////////////////////// I have built racing engines too. In fact I built one that won the Firecracker 400 at Daytona back in the mid 80's, before it was called the Pepsi 400. I have also worn out several dyno's so I didnt just fall off the turnip truck either. I did call Lycoming and politly asked for the specs and their response was " we don't have that kind of information". That's the main reason N801BH has an all aluminum 347 cu in Ford in it. Those guys at the certified end of aviation are shooting themselves in the foot faster and faster. Detroit diesels 71/53 series have had roller lifters since the late fourty's. Just last year one of the Lyc clones announced they had a breakthrough and now incorporate roller lifters in their premium line of engines. Geez...... they are only 50 years late !!!!!! I am sure Archie has wondered too why they didn't come up to speed decades ago. Thank god for the homebuilt movement and alternate powerplants. I will take the feedback from one of the posters and ca ll Lycon, I am betting they will have the numbers I am looking for to degree the cam and check the compression. Thanks again to all who have answered my post. do not archive Ben Haas N801BH www.haaspowerair.com ________________________________ Message 2 _____________________________________ Time: 11:03:52 AM PST US From: "Mike Larkin" Subject: RE: Engines-List: Accessory Case Removal --> Engines-List message posted by: "Mike Larkin" Use a rawhide mallet or rubber hammer.

I took out all the bolts but the gasket is holding it together pretty good. Does anyone have any techniques for causing it to separate without scoring the mating surfaces?

If you have a rubber or rawhide hammer hit the case on the flange all the way around, and hit it with good strong blows...

I didn't hit it very hard for fear of cracking the housing. I figured I should ask the experts before pounding away like a cave man. I was wondering if there was a secret kung-fu pressure point to aim for. Or maybe a Lycoming pry apart tool #2o02587a9sa87.... . My next attempt would be to try to delaminate the gasket with a single edge razor blade. Any suggestions? ----- Original Message ----- From: "James Ochs" > > I don't know the specifics of that engine, but on others I've been able > to tap the part gently with a soft mallet and break the gasket loose > once the bolts are completely out. > > James > > Joe Healy wrote: > >I am trying to remove the oil sump and accessory case from a Lycoming 0-235. -- -- ________________________________ Message 4 _____________________________________ Time: 07:51:52 PM PST US From: "craigw" Subject: Engines-List: Rotax Motor problems --> Engines-List message posted by: "craigw" I am working on a Steme motor glider with the Rotax 914 f engine, The problem is that on start up it with full choke it will just die after warmup when the choke is pulled off. After it warms up it may start without the choke but does not develop full power. I only seem to get about 75 percent in climb Does anyone have any expert advise on these motors? Thanks Craig
