asquaddie Posted August 31, 2013 Share Posted August 31, 2013 Had problems starting my machine lately which has been very rare so had a close inspection. Found very small bits of silver metal around the engine. After close inspection found the starter motor cog has been wearing the sprocket out. There is about one third missing on the sprockets now!!!!! Never taken this side apart yet - so I guess I need a new sprocket first. Not sure about the starter motor, because I can't see it clearly. Then replace it by attacking it from the prop end. I have just changed the back plate so I am guessing that it was never lined up when I bolted on the starter motor!! 1. Do you think I'm right? 2. Is it straight forward to replace the sprocket (anyone got a spare?)? 3. How do you make sure it is lined up with the new one? 4. HELP I'm not mechanic and don't want to cause any more damage, which I think I cause here............. Cheers guys. Quote Link to comment Share on other sites More sharing options...

( put it on and if it is not on far enough you will have to fettle the tapered hole until it goes on enough to line up) 4.

tommcb6016 Posted August 31, 2013 Share Posted August 31, 2013 I had to replace mine last year as it had partially worn the same as yours it seems As PeteB says you need to get it off first. Not easy I made a puller and had to heat it too and it still didn't want to come off! Quote Link to comment Share on other sites More sharing options...
asquaddie Posted September 2, 2013 Author Share Posted September 2, 2013 Well this is the first time I've heard Pete say 4. HELP (NO Must be getting old..... Tom - Still think I caused it when putting it back together. Phoned up Parajet and was told £67 + VAT for part and 30 minutes for labor if I take the machine down there.

tommcb6016 Posted September 2, 2013 Share Posted September 2, 2013 Probably a good move taking it to Parajet then if it's not too far? Took me a lot longer than half an hour Quote Link to comment Share on other sites More sharing options...
tommcb6016 Posted September 2, 2013 Share Posted September 2, 2013 From memory I don't think there is any adjustment between the starter ring and the starter motor. Quote Link to comment Share on other sites More sharing options...
asquaddie Posted September 2, 2013 Author Share Posted September 2, 2013 Only 90 minutes away, worse part is wasting half a days holiday. Tony Sent from my iPhone using PMC Forum mobile app Quote Link to comment Share on other sites More sharing options...
Guest Posted September 2, 2013 Share Posted September 2, 2013 Get them to send you the part dude, then just take it to a garage / eng firm. The job is a case of the correct tools. SW Quote Link to comment Share on other sites More sharing options...
pete_b Posted September 2, 2013 Share Posted September 2, 2013 From memory I don't think there is any adjustment between the starter ring and the starter motor. Correct it fits on the taper on the crank so if it is not fitting right then one or the other taper is out. Quote Link to comment Share on other sites More sharing options...
pete_b Posted September 2, 2013 Share Posted September 2, 2013 I can change it if you want tony but it will be a bit longer than 1/2 an hour. Quote Link to comment Share on other sites More sharing options...
