Car wiper blade arm hard to remove
The wiper blade arm on my car is very hard to remove from the motor
spindle, possibly because that part of the arm is aluminium and the spindle is steel. Would greasing the spindle be wise and would it make much difference waht grease I used? -- Michael Chare |

Would greasing the spindle be wise and would it make much difference waht grease I used? Are you talking about once off? The problem is that they need to be held on there firmly as any small movement that starts will very quickly get worse. I guess you could use a drop of Copper grease to stop the water getting in but I'm not sure if it would be recommended. It also might mean you could fit the arm tighter as the same torque setting on the retaining nut might result in a tighter fit on any taper and so might make it even more difficult to remove in time? I think I have used Copper grease but only in instances when it was very obvious that there was a reasonably sized spline and both faces were in good condition. If not, something like Plus Gas would help you remove it but you may also need a puller. Cheers, T i m |

Before that it's not going to make the slightest difference. Neither will all the releasing agents under the sun. -- Leave first - THEN negotiate! |

Neither will all the releasing agents under the sun. It can be used in the dark as well and whilst no release agent is going to make such a thing just fall off, it *WILL* make a difference re how easy it is to pull off (even with a puller). You could ask me how I know, if you didn't have all the answers already ... Cheers, T i m |

Unless it is positioned wrongly, normally the only time you have to remove them is if you are replacing the motor (or possibly getting access to something behind it). I'd always change blades "on the car". But yes, penetrating oil such as Plus Gas or WD40 should help, also a puller. Then wire brush to remove corrosion products.

Think that chap shouldn't be allowed near a car. Any grease used on brake pads shouldn't get near the calliper. It goes between the piston and pad, and only the merest of smears. Neither of which is ally. Just the calliper body. If a grease is required for the calliper mechanism and may come into contact with the body, you used the correct stuff for that job. I've used copper grease between wheels and hubs for many a year. If it caused any problems, would have been rather obvious. BTW, pure aluminium won't last 5 minutes in salt water anyway. -- *When companies ship Styrofoam, what do they pack it in? * Dave Plowman London SW To e-mail, change noise into sound. |

Tighten and tap (on a track rod type balljoint, not a wiper arm, although you can if you are careful). ;-) I can remember years ago we had a puncture on a boat trailer tyre and Dad got me to get the car scissor jack out to lift / hold it up. I started to apply some pressure but felt it was 'wrong', the scissors were too flat and it wasn't starting to open so I stopped and expressed my reservations re going any further. Dad took over, carried on turning when we heard a loud 'bang' from the welds on the jack and that was now broken. To be fair to him, I was just a lad but he was more of a carpenter and I probably had more 'mechanical sympathy', even then. ;-) Cheers, T i m |

Again, normally pot metal, if a casting. But to remove the arm you'd lever against the nut holding it in place. Protect if needed with some thin steel, etc. I have never had any problem with copper-slip and alloys though. Indeed, I have used it in a number of places where I had difficulty removing an item, but have had no difficulty there after using it. Quite.

The body of the arm is more likely to be 'pot-metal'. Sorry - I sort of thought it referred to the spindle body. The actual spindle is steel on every one I've seen. The taper spline has to be harder than the arm body it fits to. Fitting a new arm cuts a spline into it when you tighten it. I have never had any problem with copper-slip and alloys though. Indeed, I have used it in a number of places where I had difficulty removing an item, but have had no difficulty there after using it.

Specifically, if the arm has ever slipped before or the splines are *very* fine then I might err on making sure it *doesn't* slip over being able to get it off easily next time (which might be never). Older cars used to have clip on arms. Usually a parallel spline with a matching one in the arm. So you could only adjust by the width of the spline. Most of the modern ones I've seen use a taper spline. Which sort of cuts into the arm. Allowing fine adjustment - at least when the arm is new. I've played with wipers perhaps more than most. The old Rover had a Lucas motor which was marginal, torque wise, even when new. So I've fitted a Valeo motor which is a similar physical size, but a ceramic magnet so lots more torque. -- *Don't byte off more than you can view * Dave Plowman London SW To e-mail, change noise into sound. |
