Frequently Asked Questions

Do Case 650G and 850H blade pins fit a Case 650K, 750K or 850K dozer?

In most cases no, because the G/H series and K series use different pin and bushing part numbers. For example, the rear C-frame mounting pin R53254 fits the 650G, 650H, 750H, 850G and 850H, while the K series uses 405608A1 on the 650K, 750K and 850K. Some parts do cross over, such as the D33635 rear C-frame bushing, which fits both G/H and K series machines. Always confirm your series and match the part number before ordering.

What size cutting edge kit fits a Case 850G dozer blade?

The Case 850G uses the cutting edge kit for a 104 inch blade, SKU CS-650G-CEK. That same kit also fits the 650G, 650H, 650K, 750H, 750K, 750L, 850H, 850K and 850L. Older Case 650 and 850B through 850E dozers use the 102 inch blade kit, SKU CS-650-CEK.

Does the Case 650K blade angle cylinder come with bushings?

No, the hydraulic angle cylinder 412359A1 for the Case 650K, 750K and 850K is sold without a bushing. The blade angle cylinder tube swivel bushing 407539A1 is offered separately and fits the 650K, 750K and 850K, along with the L and M series. The G/H series angle cylinder 190595A2 is also sold without a bushing, so call (800) 909-7060 if you need help matching the correct bushing to your machine.

What C-frame pins and bushings fit a Case 850H dozer?

Broken Tractor carries the R53254 rear C-frame mounting pin, the D33635 rear C-frame bushing, the D40243 blade C-frame bushing and the D43940 upper C-frame bushing for the Case 850H. The R53254 pin also fits the 650G, 650H, 750H and 850G, as well as the 1150E, 1150G and 1150H. Matching the part number from your old part is the most reliable way to confirm fitment.

Which Case dozers use the blade slider blocks and wear plate blocks?

The blade slider block 346626A1 and the blade wear plate block 117836A1 fit the Case 550H, 650G, 650H, 750H, 850G and 850H. The 117835A1 slider block fits the 550H, 650G, 750H, 850G and 850H, so check your model and part number when choosing between them. We also offer a steel bushing driver tool for removing and installing blade bushings.
