Older Stihl 034 Clutch Cover

Hope this bar picture is ok...

Oops, it a Windsor...

There is your problem right there, the oil holes go straight through the bar, there is no outer plate to block it so it freely flows out the hole. The outer clutch cover will not seal tight to the bar, a Stihl bar will seal because it has oil delivery holes only on the side against the oil flow from the pump.

That 034 has a channel that runs from the Oiler hole down the the slot for the bar adjuster.

It needs the bar plate and clutch cover WITHOUT the side adjust hole.

Then bars with or without the Oiler hole drilled thru will work fine.

I "fixed" one of these saws with an oilng issue by tearing off the oil pump, cleaning it out, blowing through the tank breather with an air compressor and running 2 stroke gas through the oil tank and pressurizing the tank through the breather and slowly adding bar oil as it went through it.

I'm assuming that the oil pump is just worn but if it stops oiling the particular saw has holes already there for an adjustable oil pump.

These seem to be exposed to an incredible amount of debris, due care really needs to be exercised to keep it clean or regular flushes done. Got out water and a couple tablespoons of debris before going on a very frustrating adventure of not being able to get the saw to oil.

No, that is not the oiler feed slot. that is the oil tank air vent. Shouldn't be any oil coming out of there.

Not necessarily. The problem as I and @pioneerguy600 suspected is the oiler hole that goes all the way through the bar. Mark the bar and the clutch cover in the correct position while on the saw. Now remove the bar and realign it in its original position on the cover and see where the hole goes. If it is blocked by the bar cover it will oil the bar. if not it will mostly oil the backside of the clutch cover. Plumbing 101. You have a leak.

Then bars with or without the Oiler hole drilled thru will work fine.

I don't think so. Its the bar and not the cover. Get the correct bar without the through oiler hole. Problem solved.

My sorry, yes, the oil tank vent.

Why not put the bar on without the chain, tighten the bar nuts directly on the bar without the side cover, then spin the clutch with a drill and see where the oil is flowing? You would have to use a bar with oil holes in one side only.

And what kind of bar oil are you using?

Got an 034 in my shop I'm rebuilding and a parts one .... Just live outside of Duncan, probably not that far from you.

I did this too but used solvent instead of gas/oil and compressed air through the vent. The pump appears to be working, just the oil delivery is the problem.

I'll give this a try tomorrow. Bar oil is Lordco summer blend.

I'm on the South side of Cowichan Bay so ya we are practically neighbours.

Oh, and I have a what might be an 034 or could be an 036 parts saw too. Mine is missing top plastic, clutch cover, and bar & chain. Its the side adjust model. The ID plate on the recoil starter is warn off so I cant say for sure what model it is.

 

[Totembear]

Yeah, I didnt see what a hole for a side adjust chain would have to do with the oiling. I bet the oil is flowing straight through the bar, into the grooves on the cover, straight down the cover to the bottom.

Have you had the plastic cover off that surrounds the clutch? It looks like there is a ton of oil around the clutch - I am going to guess a split hose or a bad grommet behind the oil pump. Has the oil hose ever been replaced?

Yes, I have taken the pump out and inspected the suction line/screen as well as the discharge line and all looked fine. The oil you see is going into the cover surrounding the clutch is coming from the outside of the cover not the inside.

Have you bothered to READ the previous posts? Bar oil ain't your problem!

???? Lighten up! He was asked about which oil he was using. Woulda been inconsiderate not to respond.

Funny, I looked at that and started to send a message then wondered if I was starting a new public conversation. I'll give it another go and thank you for the assistance!
