Hi Everyone,
My fork truck has been giving trouble for some time with it's drive. The level is showing fine on the dip stick but the fork truck struggles and sometimes doesn't move forward. The truck works fine in reverse and even some days will work going forward but it's then as if there is a filter or strainer gets clogged up and that then stops it from going forward. I have changed the drive oil recently (oil came out very muddy coloured) but I cant seem to find any filter or strainer to clean, does anyone know where I may be able to find it?

Thanks
