rooferboy03 Posted April 7, 2010 Share Posted April 7, 2010 Hi All Have just started a strip down on the air suspension compressor and have a couple of questions. 1) What size allen key do i need for the grub screw that holds the crank in place. 2) Is it normal for the comutator to wear to a groove where the brushes come in to contact with it and if so can i have it machined flat,or is there no need to worry about it. 3) Which is the best seal to use.The reason i ask is that there seems to be a couple of different types ie Teflon and one from Holland which is said to be a re-design with teflon & fibre glass.(on ebay) Cheers RB Quote Link to comment Share on other sites More sharing options...

geoffbeaumont Posted April 8, 2010 Share Posted April 8, 2010 Commutator doesn't sound good, but hard to say without seeing it - it's either seen a lot of use (would be surprising given these motors are reputedly comfortably good for the life of the vehicle) or it's had some grit in it. I've had similar with an alternator on a car (Skoda Felicia - it was exposed at the bottom of the engine so didn't lead an easy life) - I cleaned it up as well as I could and fitted new bushes but it wore the bushes heavily and I had to replace to the alternator.

33chinacars Posted April 14, 2010 Share Posted April 14, 2010 Hi 1: ? 2: ? 3: just fitted New seal & cylinder from Goswin ( Holland ) So far so good no problems. Gary Quote Link to comment Share on other sites More sharing options...
geoffbeaumont Posted April 14, 2010 Share Posted April 14, 2010 Gary, David has told you where to look for allen key size (or why not just try them till you find the right size?) and I've given you my experience of trying to get more life out a worn commutator (albeit not getting it machined - I don't know if this is possible but given how much metal it would leave I'd spend the money on a new motor). So why "?"? Quote Link to comment Share on other sites More sharing options...
sotal Posted April 21, 2010 Share Posted April 21, 2010 So why "?"? I think Gary was just answering the original posters questions, he didn't know the first two so just put a ? by them, then answered the last one with his experience Quote Link to comment Share on other sites More sharing options...
geoffbeaumont Posted April 26, 2010 Share Posted April 26, 2010 Think I was a bit tired when I posted that - I read Gary's post as being by the original poster and thought he was saying his questions hadn't been answered. Sorry! Quote Link to comment Share on other sites More sharing options...
