Truma Motor Mover

[JohnM20]

Hi All
I have a question that I'm sure someone will probably have the answer for, possibly Damian.
I've just been looking at the space between the chassis and the motor mover assembly on my caravan with a view to fitting shock absorbers. The space looks very narrow. In checking I noticed that the roller of the motor mover only engages with about three quarters of the tread width of the tyre but that there is also about a quarter of the roller not touching the tyre at all on the inside end of it. Surely this is not correct although it is how an approved Truma agent / Approved Workshop fitted it in the first place.
It looks as though it is a fairly simple job of slackening the bolts on each side, including the cross actuator, and sliding the units outwards by the required amount. Is my assumption correct and if so should the bolts be to any specific torque? It doesn't look as though it needs any separate spacers adding in anywhere.
By doing this I would get a better contact area of roller to tyre and also gain the space needed to get the shockers in.
Any help would be appreciated.

It should be possible to relocate the mover outwards slightly, it is simply a matter of slackening off the clamp bolts and the motor to central bar lock bolts and sliding each unit outwards a little.
The thing you must ensure is that when the rollers are engaged nothing of the mover body or protrusions touch the tyres, the only part which should be in contact is the roller on each side.
You need to allow about 10mm free space allowance to the nearest solid part of the mover assembly.
The gap between tyre and roller when not engaged should be 20mm.

Torque figure for the clamp bolts and centre bar lock bolts is 40Nm

Hopefully the original fitter has left the motor cables with enough slack to allow movement,,,,,

Hi Damian
Many thanks for your reply. I'll have to check the cables before I do anything more.

I fitted a Powrtouch mover to my previous Pageant and then two years later when I wanted to fit shockers, I had to loosen off the motors and move them outwards 1/2" or so to give sufficent clearance. Quite easily done. Bolts are torqued to 40ft/lbs.
