Timberwolf CH30DH Roller Spline Drives.

[treediver]

My old backup Entec 30dh from 97 has identical top and bottom rollers spline drives in the rollers. Can I swap out the bottom spline drive to the deeper 46mm one as at the moment the hydraulic motor sits proud of the roller box using what looks like a 6mm shim  due to the drive shaft being to long for the motor to fit in the recess on the roller box.

Im not sure if that was the original design but I need to replace the bottom worn spline drive and just think it would be more secure and supported fitted in that recess.

Thanks.

Morning, yes you can upgrade to the new longer spline drive but will need to have the roller blades and body replaced as well (some early models had non-removable blades)as the blades slightly overhang the drive. The shim and motor is a separate issue , you probably now have a Parker motor fitted that replaced a White motor at some time . This replacement required the shim as the seating of the white motor in the box was different. But yes new set will fit better. Gareth of Green Plant , 01483 235111, www.shop.greenplant.com
