Installation of 2in Drawbar Pins UTBK-01 & UTBK-100
May 3, 2024 3:11 pmIntroduction: The correct installation of the drawbar pin WT1201D and WT1101HD plastic lined bushes is required for the drawbar hinge kit to perform as designed. The main function of the hinge kit is to perform as an elasticated joint and there should be no metal to metal contact of the RTB12 and 14 brackets.
Scope of this Bulletin: This bulletin refers only to the WT1201D pin in relation to the Transpecs universal drawbar hinge kits – UTBK-01 and UTBK-100. Other suppliers may have similar products that interchange but that supplier will need to provide any information in relation to their products.
Certification: The UTBK Hinge Kits supplied by Transpecs carry a certification for new installation. This certification provides for a maximum service wear limit of 5% of the original dimensions and profiles, after this the components must be replaced. If non elastic movement is found, the components require inspection and replacement of worn items. The certification is void if the installation instructions have not been followed or parts other than the original equipment items stated on the certificate are used.
UTBK PIN & BUSH INSTALLATION
Installation of Pin & Bushes:
Ensure the bush mating surfaces on the RTB12 and 14 are free from any oil or other contamination. Install the rubber bushings “HT1101HD” through the outer RTB14 bracket to the inner RTB12. Lubricants are not recommended. DO NOT USE ANY PETROLEUM BASED LUBRICANTS.
Ensure the gaps between the RTB14 and the RTB 12 are kept equal throughout the procedure as illustrated in Image A. This is essential for correct installation.
