Hello 1302033,

I have been trying to locate the sprocket drum size that you need for your saw, but everywhere I go and everybody I speak to tells me it is the 309410001. I will keep researching this and message you if I come up with an answer.

Question: Chain Brake Homelite 42CC

kenswansea

I have a Homlite 42CC chainsaw. The chain brake is annoying to me; it gets in the way of the handle and
it keeps coming loose on the left side. Can someone tell how I should go about removing the chain brake
handle or do I have to remove the whole chain brake? Thanks, Ken

Question: UT10580 Part

1205287

The part I need for the saw shows in my owner manual as a Clutch Cover Lock Knob. That is the only part I need. The only thing I can find on the parts list is the Clutch Cover Assembley.
Can I order just the part I need the Clutch Cover Lock Knob
WJA
Reply: UT10580 Part

WJA

Hello 1205287,

I located an owners manual for the Homelite UT10580. And I did see the Clutch Cover Lock Knob you are speaking about. Looking at the parts diagram, it looks like the part you are trying to obtain is on page C, item number 3, part number 518769001 Cover Knob.

Hope this helps,

Question: Muffler Screws

1176496

on the box my 18 inch gas homelite chainsaw came in ....it gives a model number zr10580, but all i can find on your web page is ut 10580. the first time I used it the muffler fell off. I was sawing in tall grass so I lost the 2 screws needed to secure it back on. Are these 2 model numbers compatable?
WJA
Reply: Muffler Screws

WJA

Hello 1176496,

I cannot locate any type of parts diagram on a model number ZR10580. You may want to look at the UT10580 parts diagram and compare the two saws. The part number for the muffler screws is 660612001. They are used on approximately 22 Homelite chainsaws. I would think the odds are in your favor they can be used on your saw.

Question: Carburator Kit

where can i find a carburator kit for this saw
WJA
Reply: Carburator Kit

WJA

Hello 1114452,

It looks as if the manufacture does not supply a carburetor kit for this unit. If you can look on the carb and see either Walbro or Zama and get the numbers off of it we do offer repair kits for some of those carbs. Just put the carburetor model number in the search bar @ www.ereplacementparts.com.

Good luck,

Question: Homelite Chainsaw 42CC

kenswansea

Hi, I have a Homelite 42CC chainsaw. The chain brake is very annoying to me; it gets in the way of the handle and it keeps coming loose on the left side. How would I go about removing the handle or would I need to remove the whole chain brake? The left side looks very easy with a phillips head screw, but right side I am not sure about. Thanks, Ken

Use a parts diagram if you have one and take pictures as you go. That will help eliminate most all the "guesswork" involved in disassembly and reassembly.
