Thank you. At least thats the homework done on price, Mine wore down the original spur sprocket to an absolute V, until it jammed. They offered up various refreshments on original design. New sprocket from L&S and this time cupped washers worked, rarely binds but saves the sprocket if it does. 2nd hand gears few and far between but it survived this. 4137 120 0600 will check this. Best wishes

Got a HL75 polesaw, which despite much attention only starts from cold with L screw tight in, idles ok with L screw being released to steady tick over, then bogs down immedeatly on throttle. Confounded 2 strokes! Amazingly, time to time over a month, it will start with no choke or throttle first time as if by magic, and once warm time and time again.Familiar? Is it a carb diaghpram problem? As far as I remember any 2 stroke starting and idling fine is not a seal or leak issue? Any help be so grateful for....

Hi Thanks for reply, I've emailed L&S direct now, hopefully they will source as no option to add the above to cart in shopping ff diagrams. Have milled existing studs but front one is dethreaded as is mount hole for it (now past any helicoil type solution as its rounded out to around 10mm and not much casing left around it anyway). Hence am going to use the alternate stud holes on the casing and drill the clutch cover in pre existing spots to suit. 99% sure the oiler holes will line up with existing bar or will have to drill out new hole on bar also. All possible. Thanks for the motivation, wish I could afford a newer Husky but like for the old 9010 is still a battleship.

Thanks all for contributions. L&S site showing not available, but yet to call: I need: 1 x 965404761 (Rubber Buffer) 1 x 024111031 (Alternate Pattern to fit rear studs Oil Guard/Guide Plate) 1 x 024232040 Guide Bar Stud 1 x 024111050 Chain Catcher Anybody help?

And in fact does anybody know if this pump cross refs with any older Dolmar models eg 116 etc

Been searching for an oiler pump for a Makita DCS9000 or 9010 same as Dolmar PS9000 PS9010 to no avail, anybody know of one out there or a supplier who can source? The beast is asleep without it

Can anyone shed any light upon the above? Will need to do if required. I can't find any info online and thought this was only an experienced based recommendation as opposed to regulation?

Thanks Paul, thats helped me clarify, i asked the Q in relation to the fact that for the sake of RFS Cert Arb for instance (as I learn today) the LANTRA Brushcutter Cert is not recognised as being on the QCF framework i.e. a 'licence' to operate as such, see... RFS - Cert Arb compertance awards I hope that this might be reviewed and as such it will go on to the QCF (or RQF 'Regulatory Qualification Framework as I learn today it now seems to be evolving in). The course was 2 days and intensive, I have spent some years on all brushcutting operations prior and trainer was very thorough and didnt spare anyone on the finer aspects of assessment. I have emailed LANTRA today to see whether this might be.

I had reply from RFS today which read pretty much as follows: (We) require a total of 8 practical tickets, 4 compulsory (see Table 1) and 4 from the optional lists (Tables 2 and 3). To achieve the 4 optional tickets you can do 3 from Table 2 and 1 from Table 3, or 2 from Table 2 and 2 from Table 3 , 1 from Table 2 and 3 from Table 3. Any of these combinations would meet our requirements that there should be at least 1 from Table 2 and 1 from Table 3. Currently we do not accept awards or certificates that are not listed on our website. .......I was hoping to have LANTRA Brushcutter cert recognised, see other thread (the LANTRA cert is not recognised on RFS Tables, NPTC is). Have approached LANTRA on the status of this, it seems that it might be likely there will be a cross reference between NPTC and LANTRA regarding this qual in the future , not sure if can be 'backdated' as such though if it should happen.

Just resurrecting this thread on a tangent, but with relevance if anybody might answer?? Not quite sure why there is no NPTC cross reference for LANTRA Brushcutter Maintenance and Operation: Code is CLMC08X The course was over 2 days, full (and thorough might i say!!) H&S training as per NPTC, practical, theory, maintenance, operation and importantly stringent assessment. In my ignorance am not sure why it doesn't have relevant NPTC crossover? Is it something to do with QCF? Be grateful for any enlightenement and clarification of how the above works?

I think that's the way I read it too, am going to be in touch with RFS soon so will keep you posted. The confusion seems to arise in the second part of the statement Quote: 'Four optional tests must be completed including at least one from Table 2 (Level 2) and one from Table 3 (Level 3)' which suggests you only need 1 ticket from table 2 and 1 from table 3......arghh taking things literally this suggests you might possibly gain another 2 tickets elsewhere possibly at RFS discretion to complete the 4 'Optional' units. If you see what I mean, the reason I mention is they used to include Tree Planting ticket as part of the optionals I believe. I have this ticket. Anyway, without wishing to confuse I have a day or two away this week so am going to clarify for myself, I will update, think it best to confirm with RFS to avoid disappointment. Well done on the tickets Adam, and well done on getting on with the course, are you doing it through Myerscough? Thanks for your replies

Glad this thread has been Rejuvenated. Reason being followed by Question? as follows. I undertook ABC awards Level 2 Cert via Myerscough online a couple of years back. I did it mostly at own cost with some limited funding (which i doubt would be available now) I found it extremely rewarding knowledge wise, and very engaging most modules being relevant to work i was undertaking at the time. One important point, I have undertaken various NPTC practical certs alongside again at my own cost since, it has taken me some time to earn and pay for these in the hope of gaining full RFS Certification. FULL RFS Certification as I understand, with the entitlement to put RFS Cert Arb after ones name if inclined requires a ABC Awards Theory Pass at Level 2 AND a full suite of NPTC tickets amounting to 8?? in total it seems from the tables provided: see: RFS - Cert Arb compertance awards I forgot about this all for a while thinking it was going to cost the earth, but now rejuvenated I find I have: CS30.1, CS30.2, CS31, CS32, A06, PA1, PA2, I also have a LANTRA Cert for Brushcutter for which the table states there is no crossover? I cannot for the life of me work out whether i'm even halfway to sending certs off to RFS yet can anyone explain how the RFS determine mandatory units from optional and 'four of each' of this and that? I emailed RFS but never did get reply?

Thanks all for replies, that has put things in perspective. Thumbs up to Shavey for the hope of a future Heavy Duty Air Filter kit.

Ok Thanks Sawchip will do, any clue on the piston diameters?

Hi all, I am still looking for definitive re. Makita/Dolmar pistons. I just bought a 7900 with problems...can't decipher the millimetres....is it 50mm for 6400, 52 for 7300 and 54 for 7900? Also has anyone found a UK supplier for heavy duty air filter kits for these saws? As per Baileys US?? Thanks, Marty

Hi all, been looking through older posts and came by this one. I am still in the dark re. Makita/Dolmar piston sizes. I just bought a 7900 with problems...can't decipher the millimetres....is it 50mm for 6400, 52 for 7300 and 54 for 7900? James did you find what you were after? I have a couple of old cylinders and trashed pistons from these saws if any good to you, sometimes alternate combos work if you're really stuck (I'm in Pembs also). Has anybody found a uk supplier for the aftermarket heavy duty air filter kit for these saws?

well, after various discussions on cutting appropriate size pipe to house clutchside spindle on outside of case, therefore allowing clutch itself to be tightened on thus effectively pulling the crank and case into place....I found that heating the case, freezing the crank (and fly side of case in which it sat) and thereafter torquing down screws in a uniform pattern, all seemed to sit in place. the bearing was proud on the interior by a fraction of a mm i would say, or it seemed to be. The new seal sat over everything nice and flush, it seemed, as it should be. Time will tell after I have given it a run out i guess.

Hi NJM you mean when reassembling the case? I foresee problems in this case as I have fitted in reverse (as it was clutch side of case cracked by chipper, only superficiallly but spoiled front of case) hence i pulled bearing and crank from clutch side and fitted new clutch side. As i remember i wasnt happy that bearing didnt sit flush on inside of case it wouldn't pull in tight, case sits tight and is airtight on both lower crank area and oil housing (so far). If it was anything less it wouldn't tick over so good. I shall expect problems if the above is the case. oh dear, it's been an enlightening experience nevertheless

Aha, may have solution (after 3 nights pain). Looking at pics of replacement worm gears, i think i might have worm gear, insert and washer reassembled incorrectly> Fingers crossed and thanks for the encouragement Arbtalkers

managed to get an original Husq replacement crank side to case, i think bearing seated aok since it's ticking over as it always did, it revs out aok, just oiler binding with clutch? hence if i engage brake it stalls. do you think an ill fitted crank or bearing seated too lightly would mean it might 'pull' the clutch on to the worm drive? it's plausible i guess if it means there was too little thread exposed clutch side and hence nowhere for clutch to go but on to worm drive. If it's this i won't pull it apart again being as it's tuning fine and no air leaks, i might just file off some of the crank (clutch) thread. everything else seats fine so. Sounds extreme i guess. Thanks for the response, got me thinking outside the box.
