Oil filler caps for C series.

[johnboy]

Hi,
Does anyone have a spare chain oil filler cap for a c-51 please.
or can someone tell me what other make chainsaw oil caps will fit?
I might even have to make up a bolt for it, so does anyone know the size and thread I would need to do this!

I am also looking for the dog teeth to go on the front of the saw.

Also I would need it posted to Ireland, but can pay via PayPal to anyone who can help.

Thanks.

If I'm not mistaken,any of the oil caps from the C series saws should fit.If you can find an oil cap from a C5,C7,C52,C71,C72,C9,or C91 it should work.Rather than use a bolt,if need be you could use a plug for plumbing.Be careful not to bugger the threads in the saw's tank.

A bolt is the last resort, I have a whiskey cork in their at the moment, but buying whiskey to keep replacing it when it falls out, could get expensive!!
So really I should be asking for a c series oil cap. I will change the ad title if I can
Thanks for the information.

Here you go,& the seller ships worldwide.

Edit:you'd better hold off on ordering this oil cap.I checked the C51 IPL & it takes a different part # - A64454.All of the C series saws may not all take the same oil cap!

Edit:OK,I checked it out & it'll fit your saw.I also found a cap that our administrator (Leon)has:

That link lead me to a oil check valve bolt, I need the chain oil reservoir cap.

I think your chain oil fill cap is SAE 3/4-16 thread .  The caps for my Super 1050 , Zip B , AXL AO and XL-12 are all 3/4-16 and fit one another EXCEPT : the cap for the S-1050 is vented 
and the caps for the Zip , SXL OA and XL-12 are solid . I don't know if the C series oil tank are vented or requite a vented cap . Look at the IPLs and see if a duck bill valve is in the cap like 
it is in the S-1050 or any other vent like a SXL AO and others 

Charles

EDIT :  SAE hydraulic  -8 fittings are also 3/4-16 thread ,  a Parker 8PNTX is a solid plug

The original link I sent to you was for an oil fill cap Part # 58339 with a check valve.If you use a 3/4 in.pipe plug as Charles suggested you'll have no vent unless you drill a very fine hole in it (as far as I know).

 Some Oil Filler Cap part numbers to help Chainsawlady with the search ;

 A-64454 - Cap
 A-64310 - Cap
 56509    - Cap

 58396  - Bumper Spike


 Here is one that would have been used on a bow bar model ;

              www.leonschainsawpartsandrepair.com/apps/search?q=56580


I've also seen a plastic oil fill/dipstick cap utilized, from an older Briggs & Stratton lawnmower engine, 
as an Oil Filler Cap on a C-Series saw , just cut the dipstick portion off .

[charles]

Do not try a 3/4 PIPE plug , totally different thread size !  The chain oil fill cap is 3/4-16 straight thread , where 3/4" pipe is a tapered thread and much 

larger .  Only thing to determine is whether the plug needs to be vented or not .  

Charles

UPDATE :  a IPL for a C-52 shows the cap to be vented and looks like #58807  ( The IPL was very blurry ) and the S-1050 takes # A-63717-C 

and both are vented caps .  

EDIT 2.0 :  Looking at more IPLs  , Homelite made a change with the C series saws , earlier versions have a check ball vent in the tank and the later ones 

eliminated the tank vent and used the vented cap .  You can use a vented cap for all versions , but only a vented cap for the later ones .

Thanks all for the information.
I will hit google here in Ireland and see what I can come up with.
Hopefully someone will have an original one I can get posted to me.
I was thinking of the dipstick idea, and now I know what to look for I might be able to find something that’s better than a cork!
