Default Engine Rake

I am in the proccess of building a test stand for Model A engines. I am using the Gleaner combine mount as mentioned before. I was under the impression that these had the proper rake in them, but prior to welding things up I discovered that the deck of the bare block is dead level. I do not have a manifold here at the house, besides the one on the delivery which I do not want to remove at this time. Does anyone have any measurements or degree that would help? Thanks Rod

3 degrees, although I have measured a winfield aftermarket manifold at 2 3/4 degrees. That should get you into the ball park

Thanks, that helps a bunch and saves on a 50 mile round trip out to the farm. I had planned on going out there this afternoon, but my plans changed so work in the instead. I wrongly assumed in this project that the combine mount had this engineered into it using the twin disc clutch to keep things lined up and square. Rod

Just shim the front of it up until the carb is level.It will take less than you would think.I cleaned up a nice manifold I had taken off an engine,bolted it to an exhaust manifold,sent it out,had it planed,and stuck it on my truck.My carb headed downhill,and the choke rod hung out in midair.I had used an industrial manifold from some old engine I had stripped.When the scrap boys here see what they think is A stuff,they stop by with it.They would rather sell me a scrap A engine for $20.than haul it 15 miles to the scrap yard to get $25.

Like I said I am using a bare block, flywheel hsg and the twin disc clutch, so no manifold or carb to level off of (they are in the parts barn). Still in the fabrication stages of this project. Possibly will post pics tommorrow evening. Using a vinatge four wheel cart to keep it portable also. Guesse some pic's will help you see what direction this is heading. Rod

Somebody--maybe Kevin in NJ?--recently posted about an industrial engine that was mounted level, with an intake manifold that had the riser at 90* instead of raked. Maybe your combine mount was set up the same way?

Could be, but it will be using common A manifolds on any engine I test, and will at some point to see if there is any difference in the industrial manifold angle. Spent the last 15 minutes refreshing my trig skills abit and the measurement is 1 1/64" diference in height front to back. Rod

Rod, I made mine out of 2 pieces of 3" channel I think and used a stock front crossmember and stock rear mounts. This will make the motor sit at the 3 degrees required. Sometimes keeping it simple is the best way. If you need some pics I can get some tomorrow.

The unique thing about the A chassis; from the front of the crankshaft thru the engine to the ring and pinion in the banjo housing, if everything is correct, forms a straight line. Sorry I don't know the degree of drop.

Plain Bill had the info, was planning on calling my buddy Mike and borrowing his gauge for setting pinion angles, but he is still in Boone, Ia. for the IMCA Nationals. Will grab a manifold while out at the farm tommorrow. For some reanon when I set it using my fuzzy math it did not look right. 1 1/64" looked to be too much. Rod

The angle is 3 degrees as measured on my car, sitting on a level floor, with a Starrett angle gauge.

Thanks Joe, I never doubted the 3 degrees, just my rusty math when figuring it in inches using the deck length and known angles. Set it to those measurements and it looked like too much. so I did not cut the angle iron to those measurements. Wish the delivery were sitting on level ground right how to dnoble chack myself. Rod

If that's for a distance of 20 inches, you're very close.

Figured at 19 1/4, which is the deck length. Rod

It is best to not breath the fumes when welding galvanized metal --grind it off where you plan to weld

I started to build a "test" stand, it evolved into a smiths compressor mounted on a rambler axle, I started with a Worthington tractor frame.
