316 no hydrolics

[jake651]

i recently replaced the engine and the mower sat for two years. it sat with the lever that allows for manual push, that releases the pressure, down from when i pushed it in the shed. now i took out the release vavles and checked them and they seemed fully functional. i turned the engine on and pressed the release vavles with the engine running and i noticed the one left of center depressed slow than the right of center. so any help? ask any ?'s if you have any

:welcome:

So is the problem/question that there is a difference in the speed of the two valves?

Or after checking them for 'function', the 316 will not move forward or back when moving the control to forward/reverse?

Any other history of things happening that might be related? Transmission fluid change, filter change?

Hope we can get some good answers for you.

i put a 3 cylinder cat diesel engine in the lawn tractor, i reomoved the wiring harness and the computer, i don't think it would but is there anything stop it from working?

 

[jake651]

it will not move forward or backwards and the deck won't go up and down

Ok.
Sounds like you are going to have to get some pressure checks to see if the charge pump is producing pressure. And I don't know how to do that on the 316.

I haven't searched TBN for hydraulic info on the 316. It may turn up something helpful.

Anything ring a bell that may contribute to this when you exchanged engines? Same engine size, etc. ?

Any movement problems before the engine exchange?
Was this tractor operated by you before the engine exchange?

it worked well before the engine blew. absolutely no problems. the new engine is a 3 cylinder inline 1.1l. so i need to check the pressures from the pump?

What way did you mount the new engine? A 316 as are most lawn tractors is driven from the blower end of the engine. If you mounted the new engine so that your driving the pump from the flywheel end you have the input rotation to the pump wrong.

 

[jake651]

your serious? the new engine rotates counter clockwise. when the engine blew i scrapped it soon after. then 2 years later which is now i put the engine in. so i figured 50/50 chance. any way i could change the pumps position to make it work?

Hey Jake

the new engine rotates counter clockwise.

Man what are the odds of that happening! Anyway,I know with the Onan being that it rotates CW,if you happen to install the charge pump housing 180 degree out it won't pump. Being you're rotating CCW,and you put the housing out 180 (upside down)..well who knows. Wouldn't hurt to try.

The plot thickens.
Let's hope for an easy fix.

You say you put a Cat 1.1 in it. You would have had to contect the drive shaft to the end with the fan and waterpump. If you look at a Cub or a Kubota with the diesel engine you'll see that they all drive the trans from the front of the engine. Actualy even the gas engine you took out was doing the same thing. I just hope you didn't run it very long the way you have it or you may have fried the pump from running it backwards.

If it had an Onan,which I assume it did. The driveshaft is connected to the flywheel. You're saying that is the front of the engine?

One other thing I forgot to mention, if you rotate the charge pump and it works you have a very slow forward but you'll go like H--L in reverse. If it was me I'd pull the engine and turn it around. Post some pics of what you did and I'll see if I can help you out.

 

[jake651]

thanks, i will look into it and see what i can do. if i have to i will build a gear box.

i didnt run it very long at all but knowing my luck i burnt it out in just a very short time lol

No, not at all.

If the engine is turning the wrong way you need to turn it around.
