Gauge Wheel Bearing Conversion:Subject: Wheel Bearing Conversion kit P/N 00769940 is designed for heavy duty conditions byallowing a larger bearing to be used in gauge wheel. This is an option that can be installed and will not beused in production. This conversion is not a warranty item (with exception of special arrangements madewith the factory sales office in advance).Service : This wheel bearing conversion kit P/N 00769940 is designed to convert one wheel, a kitwill be needed for each wheel converted1. Remove wheel from caster fork.2. Remove grease fitting and any weld on wheel

O.D. Adapter press on to install.3. Press adapter item number 1 onto wheel until

seated against wheel center. Before pressingitem 2 onto wheel look at grease hole in adapterand grease hole in wheel, they will have to bealigned before pressing adapter on. If Greaseholes are not aligned you will not be able togrease wheel. Make certain both adapters havebeen pressed on until seated against wheelcenter.

4. Screw Grease fitting item 3 into adapter, now isa good time to try to make sure grease can beput into the center of the wheel through greasefitting. If it cannot holes are not aligned andremoving adapter to realign will be difficult. Ifgrease will enter continue to next step.

5. Press bearings item four into adapters until theare seated into adapters.

6. Install wheel into standard caster fork, discardthe two spacers that were used with the oldbearing.

Spindle Adjustment:Subject: Spindle Assembly P/N 00766532 Bearing pre-load adjusting procedureService:1. Remove Belt Shields, loosen and remove belts from spindle on drive pulleys. Leave belts lying loose

on deck for later reinstallation. Raise mower up high enough to get under it, support mower on standsfor safety do not get under mower unless supported securely on stands.

2. From under mower grab each end of blade and push on side while pulling opposite side. Alternatethis action back and forth to determine if there is end play in bearings.

3. IF END PLAY IS PRESENT, loosen nut on top end of spindle. Using a thin 1-7/8" to 2" open endwrench, or adjustable locking pliers, tighten adjusting nut 1/4 turn. If wrench or pliers are not availablea wrench can be made from 3/16" thick material using supplied dimensions. (See Figure 1). Checkend play again (step 2), continue doing this and turning adjusting nut 1/4 turn until end play is removed.Correct bearing pre-load should be 5 to 14 in. lbs of rolling torque. Tighten Top Nut while holding Bladeso spindle will not turn. The bearing pre-load can be check with a inch lb. torque wrench or by sharplypushing on back side of blade giving it a spin, blade should rotate 1 to 3 turns.

4. IF TIGHT AND NO END PLAY, Loosen nut on top end of spindle, the procedure is the same as it isin step 3 except you will loosen nut to put end play into spindle then use step 3 to take it out. In somecases the bearing fit snug enough shaft will have to be tapped to loosen bearing, if this happens usecaution not to damage threads on shaft or the grease fitting in the end of shaft.

5. Removal of bottom bearing if spindle needs to be disassembled can be made easier by drilling two5/16" hole through dust cover of spindle as shown.

Models: All Models using Single Acting Hydraulic Cylinder Date:Apr. 8, 1996

Bulletin No:040896


Oil Leaking from new single Acting Hydraulic Cylinders:

There have been numerous cases of the dealers and customers replacing single actinghydraulic cylinders on new machines due to oil leakage out of the vent plug in the cylinder.

In many of these instances, no defect could be found in the cylinders. Further investigationhas revealed that he manufacture of our cylinders is leaving oil in the cylinders after their testing. TheOil is left to help protect the interior of the cylinders during storage. When the cylinders are fullyactuated, they are forcing this oil out the vent plug, causing what appears to be a leaking cylinderthrough the vent plug. Even the oil is cleaned off the cylinder after testing there is enough oil still insidethe cylinder to bleed out when used.

If you have a New Cylinder that appears to be leaking from the vent plug, The oil should becleaned off and unit ran for a few days to a week to determine if the Cylinder is leaking, or if it is theoil that was left in the cylinder to protect it. It has been found that in some cases it has taken as muchas a week for this to appear that it is not leaking.

If after running and cycling the cylinder during operation and the cylinder continues to leak thenthe necessary repair should be performed.

Cylinders that are attracting dust around them is not considered to be leaking. This dustcollecting around them is considered normal.

All Cylinder that are returned as leaking will be pressure tested for leakage to determine thecondition of the Cylinder and its components.

Bulletin No:050697(old # 050697A& # 043097R)


Springless Slip Clutch Adjustment Procedure:In order to avoid damage to the mower or clutch assembly, it is important that the clutches

slip when an obstacle which creates a load that is heavier than the clutch setting is encountered. Inorder to ensure that the clutches are properly set the following adjustment procedure must befollowed. Make note, step 3 must match the type clutch, 2 disk or 4 disk type.1. Loosen all of the 8 clutch adjusting bolts until they are loosely in the clutch. While you are doingthis it is a good time to inspect the clutch to make sure all the friction disk are in good condition andare not stuck to the pressure / drive plates. See the operators / parts manual for more detail.2. Gradually and evenly tighten the bolts to the correct initial setting. To achieve the properinitial setting. Gradually tighten all of the bolts in an alternating pattern (See Figure 2) until the bolthead and nut comes in contact with the clutch outer plate. Continuing tightening the nuts only untilthe point at which the bolt and nut can be rotated in the housing using 5 to 10 inch lbs. of force. Severalcycles of tightening may be necessary until this hand tight point is reached.3A. 2 Disk Clutch: If your unit uses a 2 disk clutch, use the proper size wrench to gradually tightenthe bolts in sequence (See Figure 2) from 7/8 to 1 full additional turns more to achieve the final setting3B. 4 Disk Clutch: If your unit uses a 4 disk clutch, use the proper size wrench to gradually tightenthe bolts in sequence (See Figure 2) from 1-1/8 to 1-1/4 full additional turns more to achieve the finalsetting

Bulletin No:102398


Clutch Disk Linings, Using Will Fit Substitute :Evidence recently revealed indicates a general attitude of many dealers to provide "will fit" or

non OEM clutch disk linings as replacement parts for the Alamo Industrial standard disk lining.

Many of these substitute disk are constructed of a material which exhibits a low pH and are,therefore, acidic in nature and tend to attract moisture. These characteristics result in a mild acidicreaction or electrolysis and corrosion of the metal components. Testing has reveled that thiscorrosion will result in adhesion of the disk lining to the metal plates in as little as two weeks time. Infact , in some cases, it was required to chisel the lining from the metal plate with a hammer and chisel.

Typical modes of failure which result from this adhesion of the lining involve many mechanicalcomponent failures to mower as well as tractor.

Clutch lining exhibiting this characteristic can be identified as being dark grey or black in color,and are available from many "will fit" suppliers. The current Alamo Industrial clutch Disk lining materialis formulated with a pH of 12 which indicates a very basic or alkaline material. In addition, the materialis impregnated with brass to provide a smooth slipping characteristic and lubrication during clutchactivation. Zinc is also impregnated into the material to provide for corrosion resistance due toelectrolysis. These standard disk are identified

Figure 1

as being tan or light brown in color, and appearto be more dense in structure than the "will Fit"disks.

Warranty claims for components fail-ures when these "will fit" disk linings are used tosubstitute for Alamo Industrial replacement partswill be subject to denial pending investigationinto the use of these. If it is determine these "willfit" disk are being used all warranty on failure ofany of the drive components, Drivelines, Gear-boxes, Blade Carriers, Clutch, Clutch Compo-nents or the Tractor itself will be denied.

Clutch Coil Spring Kits :

Subject:During September of 1996, utilization of a "springless" design 2 and 4 disk slip clutch (figure 1)

was implemented for use in several mower models. This design was used to replace the original externalcoil spring design (Figure 2), and provided equal levels of durability and safety along with a cleanerappearance. However, the difficulty involved in adjusting this clutch, along with its lack of acceptance bycustomers, has necessitated the discontinuation of the new clutch, and a return to the old design.

Service Required:Convert the new internal spring (Springless) design clutch to the old coils spring design using

the conversion kits listed. 2 disk clutch use kit P/N 00773222 & 4 disk clutch use kit P/N 00773224.The Spring Kits will include pressure plate, Bolts, Nuts and Springs (Kit will not included clutch lining)1. Remove the clutch from the gearbox. Disassemble the clutch assembly and remove thepressure plate along with the nuts and bolts.2. Reassemble the clutch using the diagram and parts breakdown located in the parts section ofthe Operators manual. Install all the parts, pressure plate, springs, bolts and nuts.3.
