Clark Equipment Company (CLARK) has warranted to the Distributor (Seller) who, pursuant to agreement with CLARK, hereby, on its own behalf, warrants to the Buyer each new CLARK product to be free from defects in material and workmanship under normal use and maintenance as herein provided.
Distributor‘s sole obligation under this warranty shall be limited to repairing, replacing or allowing credit for, of Distributor‘s option, any port which under normal and proper use and maintenance proves defective in material or workmanship within six (6) months after delivery to or one thousand (1,000) hours of use by Buyer, whichever shall occur first; provided, however, thot (i) the product is placed in use not later than one year after shipment from CLARK‘S plant; (ii) that notice of any such defect and satisfactory proof thereof is promptly given by Buyer to Distributor; and (iii) such material shall have been returned to Distributor, with transportation charges prepaid and found by Distributor to hove been defective.
This warranty does not apply in respect of damage to or defects in any product caused by overloading or other misuse, neglect or accident, nor does this warranty apply to any product which has been repaired or altered in any way which, in the sole judgment of Distributor, affects the performance, stability or general purpose for which it was manufactured.
THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES (EXCEPT OF TITLE), EXPRESSED OR IMPLIED, AND THERE ARE NO WARRANTIES OF MERCHANTABILITY OR OF FITNESS FOR A PARTICULAR PURPOSE. IN NO EVENT SHALL DISTRIBUTOR BE LIABLE FOR CONSEQUENTIAL OR SPECIAL DAMAGES.
This warranty does not apply to parts or trade accessories not manufactured by CLARK, or attachments not manufactured or sold by CLARK. Buyer shall rely solely on the existing warranties, if any, of the respective manufacturers thereof.
IMPROVEMENTS
It is CLARK’S policy to constantly strive to improve its products. The right therefore is reserved to make changes in design and improvements whenever it is believed the efficiency of the product will be improved thereby, but with- out incurring any obligation to incorporate such improvements in any product which has been shipped or is in service
The axle assembly is a full floating spiral bevel type with further reduction provided by planetary gear set within the wheel hub.
PRIMARY REDUCTION
The spiral bevel pinion and ring gear transmit power through the center differential pinions and side gears to the axle shaft. The spiral bevel differential assembly is mounted on tapered roller bearings which are adjusted by positioning of the two threaded adjusting nuts mounted in the differential carrier cap assembly. The tapered roller pinion bearing preload is adjusted and maintained by a hardened and prevision ground spacer positioned between inner and outer bearings. Spacer is selected at assembly.
SECONDARY REDUCTION
In the wheel hub, a self-centering sun gear is spline fitted to the axle shaft and drives three planetary pinion gears. These gears in turn mesh with and react against a rigidly mounted internal ring gear. The planet gears rotate on needle roller bearings mounted on hardened and ground pins located in the planet carrier which in turn drives the wheel hub. Positive lubrication keeps all moving parts bathed in lubricant to reduce friction, heat, and wear.
Broke assemblies are hydraulically operated and are mounted within the brake drum. Hydraulic pressure is provided to the wheel cylinder by a brake master cylinder actuated when pressure is applied to the brake pedal mounted in the floorboard of the operator’s compartment.
