BOLT THAT HOLDS BAR ON FELL INSIDE CASE OF MODEL 435

Yes and no. First you will need to be able to have enough room to drill the center of the broker bolt. Then it depends on if the bolt broke because of stress or seized in the hole. If you can drill the center of the bolt then you can get a easy-out tool the can extract the bolt . May need to use an anti seize spray to help. Heat may also help you retract the broken bolt.

Most all brands of chain saws will except one size smaller and one size bigger than what came with the saw. You just have to make sure the bolt holes and the hole for the adjustment pin match the origional bar.

You need to empty it out through the oil filler hole, drain the rest of the oil out, a tool with a magnet will aid puting it back through the the filler opening and back through the crankcase, as there is a square on the back take care to make sure it ligns up with the moulding on the inside of the crankcase.

The bar bolt should be an interference fit in the crankcase, if it has fallen out there is now a tollerence issue with the composit crankcsae, start by removing the oil tank filler cap, drain out the chain oil, now shake the machine until the bolt falls out of the filler opening, you now need to increase the diameter of the bolt where it fits into the crankcase or it will just fall out again, take a good centre punch and punch the shank of the bar bolt where it fits into the tank ( this will help to hold it tight in the crankcase ) now mark the threaded end of the bar bolt so as you know where top dead centre is ( you need to do this because the bolt has a square on the back which must fit into a squre socket on the inside of the oil tank ) there is a number of ways to re align it back into the bar pad, a magnet on a rod fed through the oil filler hole, or feed a lenght of thin wall tubing through the bar pad hole and out through the oil filler hole, push the bar bolt thread into the tubing, now pull it back through.Once the thread comes through use the bar nut and a spacer to pull it fully home, remember to get the top dead centre mark you did earlier at the top before pulling the bolt fully in, or the square on the back will not sit into its socket .

You do not tell us which model Poulan, that limits how much help we can provide. The head is probably in the oil tank.

Post 6 in this thread is quite good. I have seen a post that required repair of the casting (with photos) to repair. I was not able to find it. Look closely at the old one, once removed, See if it has some sealer applied
The IPL for your saw can be found here:

The 2 closest one are A & B on the map on this link

Yes, no problem

had same! was set to release the max amount of oil to bar, but the thread is only so long and will drop out of seat, send it for service and note the bar feeder srew, its faster and cheaper! good luck p.s great saw!

The fuse is bolted in to the power buss-bar in the fuse box. You have to remove the fuse box center section from the outer section (pull it up) to access the 8 or 10 millimeter bolts that holds it to the buss-bar. No other way to do it.

What has happened is the poorly designed clip that holds the pull bar to the handle has snapped causing the bar to fall out. Take the interior panel off of the inside of the door, using 2 pairs of pliers twist the end of the bar around and simply insert it in the hole it fell out of, I have had to do this to all of my doors and, unless you slam the door really hard it will stay put.
