Preparation

1

Remover qualquer bucha para eliminar desgaste futuro entre bucha e olhal de montagem.

2

Reparar qualquer estrutura danificada ex. Trincas ou olhais tortos.

3

Suavize irregularidades na superfície dos furos dos olhais.

4

A diferença entre diâmetro min. e max. no desgaste do olhal deve ser dentro de .06” (1.5 mm) para o correto encaixe das luvas.

ATTENTION! If the worn lugs diameter at any point is 2 mm (.080”) or more over original lug diameter contact your dealer or Expander System. You will need oversized sleeves. 

Installation

5

Engraxe as luvas e eixo com a graxa disponível, de preferência graxa grafitada. NÃO ENGRAXE AS ROSCAS.

6

NOTA! Se aplicável: posicione a saída de graxa a 90 graus para forçar a direção para minimizar a concentração de estresse na saída.

Assemble the mounting tool and bolt for mounting tool using the allen key screws. Insert the axle and position it in the bores. Install the sleeves, then the washers and fasteners. Tighten the fasteners with recommended torque.

7

Remove the allen key screws and mounting tool. Mount the stop screws.
