Hi guys, quick question, does the hinge rail motor have a clutch on it, i have one that refuses to lower from vertical with the slightest of pressure against it. if it has, how do you adjust it, never had this problem before, so before i go in and badger it up, i thought i would ask

Yes. You need to strip it out the hinge then take the motor apart but it’s not the best fix as once you adjust it it will need to be done again at a later date. Have you checked the battery in the hinge box?

Yes i have checked the battery just to make certain i put a 7.2 Ah on temporary, i know these motors have a bit of slip resistance, from vertical it will not lower, if you just start it lowering just the slightest of resistance against it and it slips through the clutch, get the hinge down to about “10 o’clock” and everything seems fine plenty of drive

As Nsl says you need to get inside the gearbox, which usually means taking the whole hinge arm off of the rail. Once inside there is a very simple clutch mechanism with a 10mm nut which alters the strength of grip – use common sense and don’t just graunch it up “tight as”. There’s a reason that it shouldn’t take much effort to stop its motion.
I take that it hasn’t recently had a new pair of gas springs? I have found in the past that a brand new non-adjustable pair can be too strong causing the motor to slip, or it could have been that the supplier sent down some which have been gassed up to the incorrect pressure.

it still has the original gas struts fitted, the remote for the track lowering is working, but from the upright position it will not start to lower, if you assist it it will start but you only need a feather touch to stop it, once it reaches about “10 o-clock” position it starts to react normally with the correct force needed to drive down, it raises perfectly well, it’s just the initial start to lower that is the fault.
thanks for the replies guys

If the hinge is coming up fine it is unlikely to be the motor. Have you got all your small hex bolts fitted that hold the motor shaft to the rail frame? I have known recon rail where the hinge goes beyond vertical which makes it hard for the rail to lower.
