Hello everyone!
New user on this forum here, greetings to you from Norway.
I recently got my hands on an old Fiat Allis FR12 from 1985. It's not much to look at, but im hoping to make it a reliable tool here around the workshop for those tasks that are just to heavy for the forklift.
There is one issue though, that i need to sort out before i can dare to start investing any more of my time and money on it. It has a very weak drive, even in the lower gears it is struggling to pull itself up my not-so-steep driveway. The same is true for every gear, back and fourth. The engine revs up as if was in neutral, hardly needing any effort at all.
The seller told me that it tends to get better when the transmission is hot. I have not had it at the 60-90 deg celsius operating temperature yet, because im hesitant to drive it around much untill i know im not damaging anything, but from what i can tell it seems to be a little stronger when lukewarm than when cold. But not by much.
When i start the machine cold, the transmission pressure takes a good 10 seconds before it comes up. When the pressure is up, its right at the upper end of the green scale. When shifting gears the pressure drops to zero, and takes about three seconds to climb back up. This goes abit faster as the transmission heats up.
I am waiting for a new transmission filter, when i get it i will replace the filter and the oil. I have not drained or inspected the oil yet, because i might need to move the loader around while im waiting for that effin filter. Access to parts are a bit slow up here... But i have atleast topped up the oil to the correct level. The oil looks fine on the dipstick.
I have been struggling to find good manuals on the gearbox, but am i right in that the converter is bolted directly to the engines flywheel? And the bell housing is wet? That's what my research has led me to, and it shure looks like it when im peeking into the machine from the outside. The reason im asking is because i found a missing lid on a bellhouse inspection hole today, on the left side of the engine below the starter motor. Looking through the hole i can see the flywheel, and reaching in with my fingers i can feel the teeth of the starter ringgear. And there's not a drop of oil to be seen, the back of the flywheel is bone dry even when the motor is running. That's... wrong, right? I would have expected there to be a fountain of oil gushing through that hole.
As you can probably tell im not very experienced with torque converters. So if anyone would like to brainstorm this issue with me, i would very much appreciate it.
Also, on an unrelated note: The loader has a nameplate on the left side that says 580FR10, why would that be? It is definately not an FR10, all the other nameplates says FR12, and the scales on the semi that brought it here measured it to be roughly 12 tonnes.
Thank you, i wish you a very nice day.
