ons 17 maj 2023, 08:01#801408Hello, first of all sorry for bad english. I have a few questions about forwarder valmet 828. Maybe someone knows how to turn on high gear? I don't have a manual and I can't find where to buy one, so its hard to understand about this forwarder (plus a big mess in the cab). Second question, is it true that valmet 820-828 have problems with transmission oil overheat while driving on the road? My work place is about 7-9km away from me, so i'm thinking will I be able to drive that distance (not every day). One more time sorry for bad english, I'm looking for help here because in my country no one knows about this valmet models.

If there is a mechanical high/low gear it must be located in an inter-axle gearbox, the same gearbox that the hydrostatic motor is connected to. If you can find the shifter in that gearbox then you can follow a cable wire, hydraulic hoses, and/or electric wires back to a lever or electric switch. That's how we solved problems like this before the internet was available...

thank you very much for the answer. I tried to move that lever, but it was difficult ( maybe previous owner
did not use it 😀 ).

If the brakes are applied while trying to shift the gear there can be a lot of tension between the gears if all-wheel drive is activated. Try it with brakes released and the engine idling with the hydrostatic drive in neutral

What about max speed? google says its about ~30km/h, is it true? Does this valmet model have common problems, which i need to check?
