First Start - D46U - Puffs of blue smoke

Are you sure the pony pinion is engaged? The way to test is to engage the pony clutch (do not touch the pinion engagement lever) and then turn the pony crank by hand. If the main engine turns, then it's engaged. If it is, then ways it could become engaged are:
- it already was engaged but the clutch starting dragging, causing you to notice it
- pinion throw-out spring broken and pinion gear drifted into engagement (seems unlikely given that the spring would not only need to be broken but also mostly absent to provide enough space for the gear to move into engagement)
- pinion engagement lever operated (the obvious way but you would remember if you'd done this I'm sure)

Hi Neil,
Thanks for your reply
Now that you have explained it, I may have used the pinion engagement lever erroneously. (Rookie error)
Is there a way to disengage the pinion gear to disconnect the Pony from the main engine?
Cheers
Anthony

Your post seems confusing to myself. It almost sounds like you have equipped your tractor with direct electric start also? Why the need for 2 12V batteries?
Did you mean the pony is spinning fast, or the main?
Clarification please? It would help some here offering advice. Thanks. JM

Anthony, there's a little round cover on the bell housing/transmission case, to the left of the pony flywheel as you're sitting in the operator's seat. Open that cover (don't lose the bolts) and peek inside. You'll see the end of the pinion assembly, which contains two latches. If you squeeze them together, the pinion will unlatch. Do it with a screwdriver or other bar gently so that you don't hurt your fingers. When it unlatches, the pinion end will shoot backwards and disengage the pinion gear from the flywheel. Confirm disengagement by turning over the pony flywheel with the pinion clutch engaged and verify that the pinion shaft turns but the main engine does not turn

Hi Neil,
As we say in Australia, “You bloody beauty” 
I remove the small oval cover as you said, and with much tongue poking and body twisting, I got the pinion to disengage. I then used a bit of Aerostart up the air cleaner, and after god know how many years of not running, it burst into life! It caught us totally by surprise! So a big thank you from down under. We now have a running main engine. We monitored the oil, fuel pressure and water temp and all looked good. Only the beginning I know, but the smiles on our faces this afternoon said it all. 😊
 

Good on you Meeks, well done! Very satisfying to have it running again isn't it. Anyone on this site would have offered the same info, that's what's great about this club
