Husqvarna 235 is leaking bar oil really bad

No, the oil pump is fixed and driven by a gear behind the sprocket, on the bottom of the crankcase is a large alloy screw with a slot in it, behind here is a filter for the chain oil, this should be cleaned out periodically to keep the oil flowing to the oil pump.

There is always going to be some oil under the saw, the pump is a constent loss system, oil onto the bar and chain and away, there is a lot of areas in the crankcase and chain brake for oil to get caught and drip out once the machine is set down, if the oil loss is not excesive i would say yjere is nothing wrong here.

if you tighten the panel for the bar and chain too tight it pulls the bolts out slightly out of the chassis of the body. that is why it isnt oiling properly. i had a 235 and that is what happened to mine. what you could do is file down the raised plastic where the bolts enter the body and that might help.

There is no oil adjustment on the 435 and these saws have bad oiling systems( leak oil badly when not is use and don't put out enough when running) , bad enough that it damages the bar and chain. The only solution is to use 30 weight engine oil ( bar oil is to thick). Crummy design.

You cannot just rotate the pump shaft and expect it to pump, it has to have a throw, this is done by an acentric groove in the nylon pump gear working on a steel pin in the pump cover, the bigger the throw the more oil is pumped, the biggest problem with the early model was the oil went down the side of the bar and not onto the chain, there was a later delivery/pick up pipe to solve this.

You may have gotten some saw dust particles inside the oil resevoir that got sucked into the delivery tube, thus clogging up the oiler...you can drain the oil out of resevoir and run some seafoam thru the oil resevoir to see if you can get it unclogged

With saw running and high speed hold saw close to a piece of wood and check for oiling. If still no oil, then use air pressure at hole in bar to clear.

oil pump failure, common on husqvarna

take the bar off and make sure the oil passages are clean. Then start the saw with the bar off and see if oil is coming out of the port. If not then you need to check the tube in the oil tank. If that is okay then you have a bad oil pump.It may have a bad diaphram in it.

try using thinner oil
