I have used one of these in the past.....if I am replacing the old bearings with new. No need for heating/cooling, and the taper of the tool gentle eases the bearing from the crank. Just grease the side touching the crank weights to avoid any damage, but it really doesnt need it. https://www.redboxtools.com/product/draper-14159-fork-type-ball-joint-separator-19mm/ Oh...and dirko goes everywhere...particularly your fingers, which then get spread everywhere you touch on the engine and it's bastard stuff to remove from the bits you don't want it on. wd-40 is your friend when it comes to wiping it off.

There's a good, used crank currently on 'the bay' for £40. It's a decent seller...used them in the past. Item number 336306838952.

I would pay good money to watch it in action.

Manufactured november 2024, so if the serial number has been ground out, but the silver label on the chainbrake lever is still there it will state. 11.2024

Not sure if this is any help, but the 4510 only came with a choice of 16" (66 links) or 18" (72 links) bars from factory. Both using .325" x 0.50" chain. Efco (emak) part number for the 18" bar is 50230059R, and the 16" bar is 50062014R.

Mark. The part number i supplied earlier on for the op, for the non soft start flywheel is also the non mtronic one....but yes, they need to be careful if buying used parts

Yes....would need to change complete recoil assembly and flywheel as a matched set. That soft starter is shite anyway.

Yup....if we get a saw in with a 1/4" chain, we just replace and return the old one back to the customer with the saw if they want to have a go manually themselves. Like i posted earlier a pro grinding machine isnt suited great for sharpening 1/4" chain, and for us to manually sharpen one whilst the saw is in for a service isnt cost effective. I am referring to domestic users here...if it were a pro user we would ask them if they want a new chain fitted first.

Dan. I agree, but the C-BE models were pretty rare. Let's be honest it's a pro saw. So none I know needs a 'comfort' model saw. Very popular option for the home owner weekend warrior type saws, but pretty rare option on a pro saw., and even rarer for a homeowner to buy a 261..there's a few, but few and far between.

The recommended file diameter for filing Oregon 1/4" chain IS 4.0mm (5/32") it's only Stihl that recommend 3.2mm for 1/4" chain.

Yup....unless you do it manually, don't bother trying with an approved grinder like we have in the workshop.....takes too much meat off in a pass, so at the end of it you may get one more sharpen out a chain thats needs its first sharpen after dulling off...plus the locking guide on the machine is quite proud, so you actually take a knick out of the guide with the wheel on its way down to meet the cutting tooth edge. For that reason we don't bother offering a sharpening service for 1/4" chain. Either sharpen it manually yourself or replace as and when with new..they're not dear

The flywheels are different between the standard recoil and the c-be 'soft starter' which like you say, should never be dropped started due to the twin recoil spring system. Probably no help , but the part number for the standard recoil starter flywheel is 1141 400 1200, and the complete standard recoil starter to fit it, is part number 1141 080 2104. Ironically you CAN buy the outer recoil housing without the guts of it, only for the standard recoil system, but NOT for the CB-E soft start (twin spring recoil) Part number for the soft starter flywheel is 1141 400 1202, and part number for the complete soft starter recoil assembly ready to bolt straight on is part number 1141 080 2103, with a rrp of of just the starter alone is (wait for it.....) £144.00 inc vat!!

The problem with battery stuff is theres little to no warning before it stops working. Its like a light bulb you can have it lit all day, then next it will fail....no warning. This is what i am finding with pro users who are starting to realise that is very much the case. At least with a petrol machine there is a degree of pre warning there is an issue before it finally packs up meaning the issue can potentially be addressed overnight before another 8 hours of work the next day.

Have you checked and set the valve clearances, and if so, did you do it on the correct stroke?

The c doesnt necessarily mean it has a primer. Got 3 in at the moment and none have.....the cb-e model is the 'comfort model with the primer, ergostart and tool less chain adjustment
