Savedfromscrap Posted May 11, 2013 Share Posted May 11, 2013 Hello, Just before I take the CAV starter motor on the sv2s to bits trying to find the problem... has anyone got any ideas why the motor shaft on will not pull into start position? With it all connected up and the starter button pressed a contact pulls in and looks like it is trying to move the shaft forward but doesn't quite manage it. The unit has worked a couple of times very slowly but needs sorting out. It has been sitting unused for a long time could it simply be dry grease/oil or may it be something else? Any advice would be very gratefully received. Kind regards Ryan Quote Link to comment Share on other sites More sharing options...
Gerry275 Posted May 11, 2013 Share Posted May 11, 2013 As she has sat for a while, how good is the earth lead- is it getting warm/hot. this was the prob with my 6v jeep earth- it was so slow. A better lead sorted the cranking speed. Quote Link to comment Share on other sites More sharing options...
Savedfromscrap Posted May 11, 2013 Author Share Posted May 11, 2013 The connectors are okay- it turns over lovely if someone pokes the pre selector in manually it's the pre selector side that id the problem, sorry should have said in the first place but good idea Gerry that was the first thing I checked Quote Link to comment Share on other sites More sharing options...
paulbrook Posted May 11, 2013 Share Posted May 11, 2013 It is said that only two items are needed in any toolbox - duct tape and WD40 (other releasing fluids are available) If it moves and it shouldn't - duct tape If it doesn't move and it should - WD40 I think this is in the latter category. My advice would be get it off, get it on the bench, get is soaked (with whatever releasing fluid you prefer) and work it manually till it remembers what it should be doing when you give it some volts. Oh and sometimes if it's an electromagnet that engages the pinion the core can get rust on it which hinders movement, so worth applying rule 2 to that too.

Niels v Posted May 12, 2013 Share Posted May 12, 2013 I would remove it firstly and check it on the bench to see if its moving freely. If so then check connections. Quote Link to comment Share on other sites More sharing options...
Savedfromscrap Posted May 12, 2013 Author Share Posted May 12, 2013 Thanks for that chaps, and great to see the exploded diagram! Dead right on the WD40 & Duct tape theory- left overnight standing on end with a drip feed oiler dropping a mixture of gear oil & paraffin down the shaft has worked wonders :-D Cheers, Ryan Quote Link to comment Share on other sites More sharing options...
