Motor mounts for my 825

[jeffco]

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.

Good to hear you had success finding cheaper parts. Its amazing what new engine mounts can do. I found that oil leaking that pools or sits around the mounts make them turn soft and they sink like yours did.

I bought from McMaster Carr. My motor mounts appeared to be original and unmodified even though they are equipped with a spacer which is listed in the parts book so these mounts were an excellent fit for my 1980 825 with a 4.108 Perkins. Motor mount part number is 6309K3 and I used 65A durometer, you will need 3 at 5.95 each with the super heavy duty flat washer included. These mounts have a 1/2 inch hole for a 3 1/2 or 4 X 1/2 inch grade 8 bolt. I also replaced the radiator mounts to stop that pesky noise from the fan hitting the shroud. Radiator mount part number is 6309K2 and I used 45A durometer, you will need 2 at 5.70 each with the super heavy duty flat washer included. These mounts have a 3/8 inch hole and the radiator studs are 3/8 so perfect fit. A little shipping and you are all set for a little over 30 dollars, what a deal!! Good luck, jeffco
