New parts fitted, all seems good. Thanks to all for advice. A

Yup Heard last night, FRJones,,, Oh well. It wasn't a massive parts order.

still waiting for the parts,,, Does anyone (also) think that there maybe a shortage of Husky 550 Mk2 plastic work drives for some weird reason?

pump assembly and worm wheel ordered

💡 Lol. Going to admit I didn't take it apart but took the saw to FRJones who broke it down until he found the cause and then ordered the bits. Very helpful.

It was the oil pump assembly, this plastic plug thingy was welded on, once off crank turned as normal. replacement bits ordered, thankfully only £20 or so. Design fault?? That drive sprocket is the original from new. Not exactly worn out??

Thanks everyone. Turned motor over by hand, then defeated the hood safety switch, gave the starter a tap and bingo! All good, very grateful. Just bent jockey wheel mounting point to sort and we are good to get out there,,, A

450hrs, regularly serviced but not been used for a while is due its annual service in next week or so. Battery fully charged (but it is the original battery from new, must be 4+ years old). Diesel 3 cylinder Lombardi engine. Go to start, glow plug light glows and then goes out after about 10secs as normal and then I turn the key. Just get a click, nothing else. Belts are disengaged (tried tensioning and untensioning just to be sure). Tried with a 500w lithium Halfords battery booster; made no difference. If "we" cannot find a way to get it going, does anyone know a dealer or mobile chipper mechanic near Sevenoaks Kent (J4 or 5 M25)? JASWilson want me to pay £500 up front before they will look at it plus 5x£33 travel extra if they need to go away and get more parts (wtaf!!!) Cheers Andrew

Thanks all, (spudulike) the chain/bar/ side casing are all off and the clutch still cannot spin the drum/sprocket. The melted oil pump drive gear sounds most likely since I have been greasing the crank bearings and the usage is not huge on this saw. Will delve deeper and let you know,,, A

Thank you. So definitely that and not the oil pump? If so, is it a dealer workshop job to swap seized bearing for new? Cheers Andrew

Hi, Scratching my head at this one. Just over a year old 550 Mk 2. Starts and idles fine and throttle picks up but chain will not spin, as if the chain brake is on. Removed bar and chain, and side casing off still happening. Grease point at clutch regularly greased, not done hundreds of hours. Unable to turn clutch/sprocket housing manually,,, Could it be the oil pump has seized? Thank you Andrew

"Guilford or Leatherhead", it appears, having googled Lawinds,,,

Hi Whereabouts in the "south east" please? Cheers Andrew

It would be great to see an installation diary if you could find the time. I think lots of pepes on here would be vvvv interested. It would give you a record of it as well and maybe make potential problem solving easier, if you needed it?
