1 TECHNICAL SERICE BLLETIN RAFNA RAILGEAR ISSE DATE: June 17, 2013 TSB NMBER: TSB-190 Rev 0 HAZARD / RGENCY RATING DANGER - Physical harm is possible if TSB is not observed or followed WARNING - Equipment damage is possible if TSB is not observed or followed CATION - Essential issue affecting operation, service, parts or installation INFORMATIONAL - Advisory which may be of interest APPLICABLE EQIPMENT: R290 Railgear SMMARY: Wear at the Inner Guide Tube Axle Guide Tube Pin area on the Axle has been found at various degrees of wear depending upon age of unit and amount of Maintenance performed on Railgear. IMPACT: Excessive wear in this area can lead to an axle failure. ACTION: Inspect this area as follows to determine the amount of wear acceptable before axle change is required: Primary method of Inspection Inspect vehicle as close to actual use by means of, rail, alignment rack, two by fours or steel tubing. Deploy railgear and observe or measure axle movement at the Axle Guide Pin Location. You can have 1/8 of wear in both the up and down direction from center line of the Axle Guide Pin. This would be a total of 1/8 up from center and 1/8 down from center, for a total of ¼ wear. If the ¼ wear is all up from center or all down from center, then this would not be acceptable. If axle is out of specifications replace with Axle R Pin should show no wear. If pin shows wear replace with P/N, R990KIT 353. Alternate method for inspection Lower Railgear until it is resting on the ground without any load being applied to it. Remove 5/32 cotter pin and slide bellows out of the way, then remove Guide Tube Pin. Now inspect axle and pin for wear. Replace pin and cotter pin and proceed to other end of axle and repeat inspection process. Inspection process for pin wear and axle wear is as follows: If pin shows wear replace with P/N, R990KIT 353. se Alternate Method of Inspection drawing which shows limits of wear for slots and holes. se appropriate measuring tools to perform the required measurement. Measuring tools will vary from location to location. If Axle is out of specifications replace with Axle R 2930.

2 Rev 0 If Axle is out of specification replace with Axle R If Guide Tube Pin, P/N R 2949 has any wear replace with R290 Axle Repair Kit, P/N R990KIT 353 Attached to this TSB is a revised copy of G&B Specialties FRA Inspection for R290 Railgear. This revised FRA Inspection form is issued to insure that the (Rafna) G&B Specialties R290 Railgear is inspected and serviced correctly. Items of concern which can create premature wear and failure to the axle in the area of the guide pin, but not limited to, are as follows: Improper over center adjustment of the Railgear, over center must be 2 ~3 Max. Hi Rail wheel loads should be set at 450/550lbs. Min/750lbs. Max. Wheel wear must be checked using P/N S ; wear on wheel must fall within specifications called out on Wear Gauge. The GWR of the vehicle must be maintained to insure that the R290 is not overloaded.
