Not a chainsaw, but does anyone know where to buy these? They are from a 1973-1979 for bronco or f100?
Thanks

Have you tried here?:http://broncograveyard.com/
 
I'm surprised there isn't a fill line, that old gear drive Poulan I got had an oil fill line.
No fill line...
I think it has to all come apart. There's thick tar-like sludge all over in the gearbox. Don't see much oil in there either... I think the bearings need to be replaced too.
Uggh.

Well today has been a long day, and somewhat frustrating lol. This evening I removed a little rotten storm damaged tree and was quite excited on using the ms361. I was smart and brought the 017 and wouldn't you know, the little gremlin 361 wouldn't stay running! So the 017 did all the work again lol. Definitely carb issues and probably fuel vent also.
I learned a bit about notches now also. I cut it at too shallow of an angle, so when I tipped the trunk over it hung up for me. Oh well, learned lots tonight, best of all with a low risk factor.

Update: no gear oil AT ALL! [emoji32]

Also, I bought 100ft of .404" x .058" chisel chain, and found one drive link that measures .063"

What would you do? Sand/file on the thicker link till it fits in the bar, or splice and repair the chain with the correct link?
 
Getting deep in this Poulan 3300 build.

It's getting ported with a 2 piece head, Poulan pro dual thin ring piston, full size countervibe clutch, 3/8-8 rim, obviously a healthy muffler mod, and I'm going to try to track down a big intake and carb off a later model saw like a 3450, 3750 or something.

Clutch mocked up for fitment.

Clutch cover windowed to clear clutch.

Junk head cut down to test fitment.

New head is 2/3 finished.
 
Pulled the jug off the 5200, nice and pretty inside and piston looks good. The piston rings are just as thin as the oil control rings on a Chevy small block. Hard to believe rings that thin can build up compression. Going to clean up both p/c tomorrow at work in the vate and do some polishing on them .

Haha, I'm getting there with that Mac 250. In order to get the carb box/handle off; the oil tank needs to come off which means you also need to take the gas tank apart. Seems logical lol! Well at least I will get to inspect everything while I am at it.
Hey Mac ---Let us know what you use to reseal the 4 shouldered bolts and 3 screws in the gas tank with. What have others used to make a leak free tank? I have one apart on the side and would like to put it together only 1 time. Need to make up all the gaskets also--Thanks David

I'll let you know, I haven't searched much yet. Thinking motoseal at the moment.

I'm also surprised it doesn't have a fill line. All of my gear drives (4) have a sight window for oil level. You could likely clean it out with varsol or kerosene, but all of my saws had a pretty thick layer of sludge built up.

if there is no fill line, then I would say fill it no more than about 1/3 of the way full. That seems to be where the fill line is located approximately on my saws. As long as a portion of the gears are immersed then when its running it will be fully lubricated.
