Hi Vint_mow, you want to try changing the drive belt on a G model Deutscher. To replace the belt you have to remove the pulley on the gearbox. Only problem is you also have to remove the wheel and that just took me 2 and a half days and several people giving it a go with the 10 ton puller. This is why some machines go to the scrap. Maybe the belt you listed might help but there is no adjustment on this belt so you would have to pack the motor up with spacers
