The Techno Double step on our Autocruise Starblazer recently stopped working in the up position. Suspect 12V electric motor as it had become lazy in retracting fully, needing a knee up to retract fully.
Stripped step & motor down and it's fitted with an Italian UNUS International Macri PM32 Gearbox motor.
Further stripping down motor, it looks as if the armature sprung brushes have worn out.
Can you buy these as spares in UK??
Second question.
Had to split the step from rear fixing bracket as one of the retaining bolts was turning and not unscrewing.
How do you get to the heads of these bolts??
I believe CAK tanks keep parts.
Unfortunately I think all the pivot bushes have worn out on mine and no one lists replacements.Not a good product me thinks
Motor brushes can be quite common between different motors. I'd take a brush to a vacuum cleaner/electric drill repair specialist, probably fine something alike or RS catalogue.
Thanks for info, was going to try electrical motor supplier in Derby for brushes.
There aren't any bushes in step pivots just 13mm across flats nyloc nuts & bolts which have a square taper and a domed head. Between the moving arms of the steps are plastic washers.
It's easy to remove one, just unscrew nut then knock out with a plastic mallet or piece of wood to protect thread end.
be careful to make sure you get both plastic washers & steel washer, per pivot point.
Check if there is wear, grooving on bolt, replace if necessary.
You should be able to source them and washers from any good
engineering/hardware supplier.
When you re-attach use new nuts and tighten up then back off a little to allow them to hinge.
Cheers, I'd assumed the plastic washer was a bush but now it's clear it's not so well made If the bolts have simply worn a groove that's an easy job but if the holes in the brackets have worn it is less rosy barring fitting 10mm bolts.
We only use our step on arrival and departure until we put a floor standing double step in place. This is because the chassis mounted one acts like a big lever when stood on and rocks the van.
Don't think it's feasable to fit wider bolts as you are restricted to the
square cut out in one of arms to stop dome bolt turning.
have tried loads of places for motor brushes but most people just want to sell me a complete motor for £126 + shipping.
Lot of brush supliers say they can probably match them up if send a sample.
Another avenue is to look for a cheap Fiat, Peugeot, window motor on ebay which use similar 12V motors.
