Replacing the follower gearbox drive belt on a Bobcat S175 skid-steer loader is a critical maintenance job necessary for making certain appropriate cooling system operation. Failure of this belt can result in overheating and possible engine damages. This procedure needs mechanical capacity, adherence to security procedures, and the appropriate substitute belt defined in the machine’s service manual. Always seek advice from the main Bobcat solution literature for the most precise and updated info particular to your maker’s serial number. Continue just after acquiring the essential tools, consisting of ideal wrenches, sockets, and the new belt.

Focus on security. Park the machine on a firm, level surface. Engage the hand brake safely. Fully lower the lift arms and attachment to the ground. Shut down the engine totally and eliminate the ignition secret. Enable the equipment adequate time to cool if it has been running recently. Use suitable individual protective devices, consisting of shatterproof glass and handwear covers, throughout the treatment. Failure to comply with these steps can cause extreme injury or death.
Accessibility to the follower transmission drive belt is obtained through the rear engine area. Open up the rear door or eliminate the rear gain access to panel according to the specific design of your S175. This normally includes launching latches or removing a number of fasteners. Meticulously established the panel aside in a safe location. With accessibility granted, situate the fan gearbox setting up installed near the leading back of the engine compartment. Determine the belt directing course diligently. It is highly recommended to picture or sketch the existing belt’s path over all wheels (crankshaft pulley, gearbox pulley-block, tensioner sheave) prior to continuing. This aesthetic document is important for correct reinstallation.
The belt stress is kept by an automatic tensioner wheel. Using the appropriate size wrench or outlet, rotate the tensioner pulley arm against its springtime pressure in the instructions defined in the solution handbook (typically clockwise or counter-clockwise). This activity releases stress on the belt, permitting it to end up being slack. Do not require the tensioner past its made traveling. Very carefully slip the old, used belt off each sheave, following the noted transmitting course. Check all pulleys for too much wear, damage, debris, or imbalance that might add to premature belt failure. Tidy the pulley grooves if required. Contrast the brand-new belt with the old one to verify it is the proper length and type prior to setup.
Transmit the brand-new belt precisely according to the formerly taped course and layout in the solution manual. Ensure the belt is properly seated in the grooves of all pulley-blocks, beginning with the crankshaft wheel, then the transmission pulley, and ultimately the tensioner sheave. Confirm the routing versus your referral picture or sketch. When the belt is appropriately placed on all pulleys, gradually and carefully launch the tensioner wheel arm, allowing the spring device to apply tension to the brand-new belt. Avoid squeezing fingers throughout this step. Validate the belt is fully seated and focused in all pulley grooves.
With the brand-new belt installed and tensioned, manually revolve the engine crankshaft slowly utilizing a wrench on the crankshaft sheave screw (adhering to the normal rotation direction). Observe the belt for a number of full rotations to confirm it tracks correctly without jumping off any kind of wheels and that there is no binding or disturbance. Re-install the back gain access to panel or door securely, making sure all bolts are tightened properly and any kind of latches are engaged. Do a final aesthetic evaluation to verify no devices or particles are left in the engine compartment.
Start the operational test. Reinsert the ignition secret and begin the engine. Enable it to idle at first. Listen very carefully for any unusual noises such as squealing, chirping, or grinding emanating from the belt drive location. Aesthetically examine the belt via the back grille or access while the engine is running (workout severe caution near moving components) to confirm smooth procedure without extreme resonance or wandering. Screen the engine temperature scale carefully throughout a quick low-power functional test to make certain regular cooling function is recovered. If any kind of abnormalities are discovered (sound, sliding, overheating), promptly shut down the engine and re-inspect the belt setup, stress, and routing.

Successful belt substitute restores essential cooling down system feature. Preserve a document of this solution, consisting of the date and belt part number mounted. Regular examination of the belt problem and tension, as component of regular maintenance, is important to avoid unanticipated failing and costly downtime. Constantly refer to the main Bobcat S175 solution manual for exact torque requirements, detailed representations, and any type of model-specific variations.
