Default ch23 oil pressure

didn't find anything in repair manual saying what oil pressure should be . i have 40 psi while cranking. the problem i'm having is the lifters are holding the valves open and therefore has no compression. i removed the lifters and squeezed the oil out of them and the first 2 revolutions had compression then nothing . the valves are free . and function as should . i put air into the cylinders with the rockers off and have no pressure leaking by the valves . i removed front cover to inspect oil pressure relief and all seems ok . i'm stumped

What you are describing seems confusing....but I'm wondering if you have valve seats, and if you do, has it moved?

I'm not familiar with that engine, but if the cam-to-crank timing has moved you will not get compression but you will still see the valves moving.
it would not be too difficult to turn the engine over with your hand or a wrench with the plugs out observing the valve operation.
as the engine comes up on compression to top dead center, both valves should be closed.
and as the piston comes goes back down, then just starts back up you should see the exhaust open.
also make sure you are turing the engine in the correct rotation.
and remember it is a 4 stroke so you need to be looking at the compression
stroke to start, not the exhaust stroke.
Excuse me if you know this, as I have no idea of your knowledge.

Well that makes sense, kind of figured that.
Glad you found it, thanks for letting us know as it helps others.
Hard to believe they didn't key things so that don't happen.

I'm curious, is the gear and crank marked in some way?
In other words, with no key, how can one tell that the gear has shifted from its original position?

This is a situation that could drive you crazy if the gear moves just slightly but yet the engine could start and run, but not run right.


Edit: Found this video on YT. It's worth a look....

no markings other than the timing dot mark , i had another crank here that i looked at and seen the problem . i pulled the gear off lined up best i could with keyway for pto clutch and the casting mark on the counter weight . i cleaned it up put red loctite on the crank and heated gear and installed back onto crank. might not be perfect but it seemed to run good today

If that new gear is hardened, I don't think I'd be hearing it up cherry red.
more like *350 in oil, would be my choice to preserve the hardness of it.
-----just my un solicited opinion.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
