Eveything you wanted to know but were too afraid to ask.
After a few increasingly lethargic efforts, the step refused to engage. Not catastrophic, but a nuisance, so in the glorious weather of today I decided to have a go at it.
3 bolts released the device from the frame, tho one sheared in the process. It was filthy.. just in front of a rear wheel, it is effectivly located in a wheel arch. Ridiculous, another point of proof that Germans have a sense of humour after all.
Anyway, 2 torx fittings release the motor from the gearbox. As it is a worm drive, I split them by unwinding the gearbox off the motor armature.
Once free, the motor spun happily on the switching, so on to the gearbox. It was completely jammed.
I found an 11/64 socket fitted perfectly onto the gear drive cog, so with a big wrench I ground the thing free.
Perhaps naughty, I tipped some engine oil into the gearbox and continued turning the stiff shaft. After a while it freed up enough so I put the motor back in position.
*NOTE* as it's a worm, you have to 'screw' it back in... it would not go fully home, so I applied the electric, [the up switch spins it up the right way] and it wound in perfectly. Manually it was just not working for me at all.
I ran the motor for a few minutes in both directions, knowing that there was oil present that hopefully in theory would work it's way into the shaft. It sounds like it did when we first got the bus, so I reckoned it was good enough to go.
Re-mounting the assembly was straightforward, and now the step is working fine again.
As an aside, it looks like the gearbox is locked shut with some weird riveting process that I really did not want to start messing about with. Effectivly a non refurbishable item.
Thanks to Bjorn I've managed to fix Herman's electric step
A great practical video mate...The best kind
Brilliant!! No better feeling than when you manage to
Fix something like that and save yourself a shed load of cash ! Well done you!!
great video , mines been playing up for a while now , i know what my job is this Sunday , hope i have the same success !
Good luck, Lee. Let us know how you get on.
Great fix :-)
Well done! you just made a step in the right direction Ads LOL! The challenge now of course is to keep it that way with preventative maintenance in stead of reactive.
True but I don't think there is a way of maintaining it
My advice is.The mechanism seized up probably due to the elements getting in & you freed it up with penetrating oil so give it a good drenching all round occasionally which should help. You could invest in an aerosol tin of Waxoyl from Halfords & give all the gummings a good coating to help stop water ingress around the cog shaft too.
My step motor doing the same thing. It’s relatively new as well (1year old) so will try this and let you know how it goes get on. Hymer 534, year 2000
Good luck with your step, @03Timm. Yes, let me know how you get on 👍👍
Good job saved a lot of cash .
Great video, learned a lot about how to fix a jammed step, thank you and well done for the end result you achieved
John
Thanks John. Glad to be of help. Do you have a problem with your step?
Yes Herman
The step is jamed in the out position. We did everything you where advised to do, ie- bang it with a mallet, vibrate the step ect ect, but to no avail, so had to drive reluctantly with step out, so need to get the motorhome high enough for me to get under, to try removing motor, ours is at the back of the steps out ofreach like yours 🤔
Could you try driving head on up a curb to give you clearance? A car park should have plenty of room and curbs
I will use the 2 levelling ramps i use when parked on uneven land, that should lift it at least 6-8" up, then put blocks underneath just incase to make it safe, to get under the vehicle, will let you know Herman when iv had a go at it, 👍
Excellent John. Just so you know Herman is our moho. I'm Ads 👍👍😉
Thanks, very usefull
Glad it was helpful, Oscar!
Loved it watch out Ed China
I used to love watching Ed China fixing up cars. I always thought that the show never went deep enough
