I recently replaced all three motor mounts and the two radiator mounts on my 825 Bobcat/Perkins 4-108. Any way all 5 mounts from McMaster Kar supply company were less than 30.00 and I had them the next day by UPS. They were a perfect fit and I ordered them in the harder durometer, hoping for good long life service. All this stopped that clunking noise, and the drive coupling mis alignment and the vibration that it caused. The previous owner had opened the exhaust hole in the rear cover to about 6 inches in an effort to offset the sinking engine and to keep the exhaust exiting the engine compartment. The radiator mounts stopped the fan from hitting the shroud. Like running a different machine now. Hope this helps others because the mounts are pretty standard and McMaster has good coverage. Jeffco
