Makita dcs4301 clutch drum

[pieandapint]

Hi folks, long time lurker first time poster. I'm having trouble finding a 3/8 LP clutch drum for my dcs4301 and was wondering if there is anything else available that's compatible? 

 

Is this due to makita no longer manufacturing chainsaws? 

 

All the clutch drums I can find seem to be missing the tabs on the back which drive the oil pump. 

 

Is it possible to convert to a splined clutch drum to accept a 3/8 LP sprocket? 

 

Sorry for all the questions! 

Dave

The correct part number is 158927-9 and you can purchase here, L&S are a good supplier so don't take the "not in stock" for they can't get them in. Generally it means that they will put an order in to the main UK Makita distributor and it will be days away. This seems to be the only OEM part available : -

Thanks but that appears to be 7t vs the 6t that came with the saw. I think as parts seem to be drying up I may be better getting a splined clutch drum with separate sprocket as I'd like to continue running the saw for a few more years and sprockets may be easier to acquire. 

 

I'm just scratching my head regarding part numbers.

 

I believe I'll also need a shim for behind the clutch drum, needle bearing, and of course a 6t sprocket.

That last bit might undo your plan....not sure a 6T rim sprocket exists.

Dont forget the outside diameter of the rim sprocket is proportional to number of teeth - that's to say a 6 T rim might be too small to function on the splined clutch drum.

Happy to be proved wrong.....

Oregon 18720 i think would work

I didn't fit a rim sprocket yet as still have a few spur ones bough as spare to use up first.

 

My makita came with .325

Just realized going from 6 to 7 tooth  will incerease chain speed by 12%   so not ideal

 

 

Spur 3/8 LP 6 tooth sprocket and 325 7 tooth sprocket -  the 2 stock configurations give nearly the same chain speed .

[shavey]

if you need a 3/8 spur sprocket for your saw I have some packed away somewhere and I’ve got .325 spur sprockets

as @Stere says if you can find a 3/8 lo pro rim sprocket

you can use a clutch drum from Ea-5000 or ea-6100

 

or if no joy try your stiga dealer and get a 3/8 lo pro spur 

sprocket for a stiga sp-386

Don't worry about 7 tooth spur sprocket on 3/8 lo-pro. 2 years ago I ordered a 6 tooth from my local Makita dealer for my EA4300, which is very similar to your saw. Makita supplied the 7 tooth, when my dealer queried this he was told by Makita that they were only doing the 7 tooth in 3/8 as it worked better. Took so long to arrive I bought replacement .325 bar and chains instead.
