Engine ideas

[gravelymay]

I checked the clearance between the engine on a old Gravely gear and the planetary Gears there was 1/16 inch.
Also double ck the distance from the edge of the transmission
The engine stuck into the trans 1.11/16
But to the Planetary was 1.3/4
Thanks Bruce g

Thanks, Bruce. Wont be able to do much on this until next week.

Looked at the hi/low planetary today. I have an extra gravely drive pinion gear so I put it in the tranny and turned it by hand to see what the planetary would do. In one position (not sure if hi or low) the large internal gear was stationary while the planet gear carrier rotated. In the other position the planet carrier was stationary and the large internal gear rotated. As far as I can tell this is working correctly. The springs needed adjusted on the hi/low shift rod but other than that it looks good. So now I am back to the problem being either the gear on the new engine is too far in or it is not aligned properly and rubbing severely. I got a thick piece of card stock (about 1/16") and cut a new gasket out of it to use as a spacer. Will try it out this weekend.

That is about all I can think of right now.
Another thing you can do is turn the gear.shaft.
off a little if you need to shorten the crank.
It maybe only a 1/16 of a inch.
Here is a couple of pic of what I had in mind but my pictures are not clear.
But my spacer need to be thicker and I need clear pictures
There is about .090 clearance on the Kohler transmissions.
Verse .063 on the model L transmission

Thanks Bruce g

Frustrating day. Took off work a little early to try out spacers between engine and tranny. It took about an hour to mount everthing and add oil. Start up Chinese engine - it runs for 15 seconds then dies. Wait half an hour. Starts - runs for 15 seconds. Wont stay running. Engine has only ever been run twice for a total run time of maybe 10 minutes. Ran perfectly then. So now I have to determine whats wrong and fix it or see if I can get Lifan to fix it. I'm starting to think this project is snake bit...

Ck your gas dump it and refill.

Maybe the low oil shutoff is killing it?

Good suggestion along with Bruce's about gas. I did check the oil level and its good but if the sensor is bad it can still kill the engine. The engine was purchased in January so it may still be under warranty. Dont want to do anything to void the warranty so I need to talk to them about it before tearing into it.

Drained a pint of gas out thru the carb bowl. Engine started and ran fine. Wont get a chance to test ground speed until tomorrow. Thanks.

Tractor still runs fast as if hi/lo is frozen. I do not think the gear is in too far with the extra spacers, hence must be something else. Will think about this some before deciding what to do next.
