Engine ideas

[gravelymay]

Hi One
I have been thinking .
You just put it together?
So the clutches are going to be dry ?
So try shifting in low a while and High a while back and forth?
As some would say work it.!!!!
Just a through ?

Is there no longer a hi/lo range?

Is it just that the higher rpm of the new engine makes it run faster?

If you move the hi lo lever it don't change speeds?
That is the lever I am talking about.
The hi low pto lever.
Also forward and back lever.
Move them a lot to change to see if it will turn loose?
What Rpm are you running your engine?

Hi! I would try to adjust Hi-Lo bands levers .In tranny you have planetaries and bands clutchs. This ones (bands) stop or free the planetay for reduction speed. I think your HI-Lo planetary turn dont stop for reduction. Because band too loose or input shaft too tight. Good Luck ! Oldmech

Let me address some issues brought up by the past few posters. Moving the hi/lo shift leverl makes no difference on tractor speed. This is even when the engine is idling (i.e very low rpms). I pulled the planetary out to inspect it. The brass (bronze?) bushing into which the 3/4" stub on the input gear fits is scored about a half inch inside. You may remember the 3/4" stub on the gear I used was cut down to accomodate 7/16" internal hex cap screw. So the scoring is probably due to a mis-alignment of some sort. I read some posts on the Yahoo Gravely Club site that indicated worn or scored bushings can cause the planetary to behave badly. With that in mind I re-aligned the drive gear to be sure it is dead in the middle of the tranny case. Upon trying the tractor again it still does the same thing. By the way other than the bushing the planetary looked to be in good condition. The "bands" was not very worn and appeared to work correctly. In one position it stops the internal ring gear and in the other position it stops the orbit carrier.

So here are my thoughts at this point. I'm thinking the short 3/4" drive gear stub could be a problem. That stub acts as an axle for the planetary and Gravely designed it to be a certain length. Maybe cutting it off does not let it work properly. The scored bushing probably needs to be replaced. There is a 2nd bushing in the planetary which I cant see. Maybe I should ship the planetary off to someone like Richard's and have it rebuilt. Finally I wish I could measure the TIR of the 3/4" stub. Maybe my settup of sleeve and bolt is not holding it true on center. If that were the case it could rubin the 3/4" bushing.

What are your thoughts?

I am working on a C10A that has been apart for 10 years (Basket case).
I have got all the parts and a new 13 Hp Honda manual start.
except the clutch cone.( back ordered from Gravely)
Got most of the stuff painted.
While I have a engine I plan to make the 2 spacers and drill a old Kohler adapter to fit the old L transmission I already have my crank adapter.
So I am kindly slow.
If I get it done I will post Pictures
Thanks Bruce g

Well I finally got the clutch in?? from Gravely
It took 2 months.
So here is a C10A with a Honda.

Thanks
I hope to have it going tomorrow after being torn down for 10 years and laying a guy's shop all that time.
I still have to put oil in the trans and ck every thing out.

thank bruce g

Well I plan to repower a C10 .
It is like the L except it has a Kohler engine and adapter and the crank has been turned down to fit the small gear.
I'll post pictures as soon as get them
