Hi folks, I've got an issue with my Dolmar 133s. It's not oiling so I removed the clutch for a look. The two retaining screws were missing from the pump housing for a start and the feed pipe was disconnected.

 

I put new screws in and connected the pipe but when I fired it up I can see the oil seems to be coming from behind the pump rather than out from the hole it's supposed to be coming out of

 

Do I need a puller to remove the clutch hub? I'd like to get the pump off and check theres nothing broken or blocked. I'm also not 100% sure how the oil gets from the pump up to the oil hole normally, if someone could give me a simple explanation I'd appreciate it

It looks like you are missing a pipe to take the oil from the end of the pump to where it goes into the hole in the bar. I'm not familiar with Dolmars but is there a cover plate under the clutch side as well ?

Not on the bench but on the floor! Had a wire rope jam up in the 1t tirfor,

Had to totally dismantle it to cut the wire, then couldn't remember how to put it back together again!!! so got the 3t out just to make sure! All working fine now!

This should help you hopefully

Look at Page 6 Item 8 (pipe seems longer in the ipl possibly as been said?)

I think the clutch centre needs to be just pulled off using a puller or slide hammer using the 3 m5 holes. if I remember rightly it just sits on a tapered shaft.

Finally got the sparkless 026 running. Still no idea what it was:

 

3 coils, all with very similar resistance across primary and secondary.

 

2 flywheels, both seem fine.

 

All wiring torn down and tested/replaced.

 

Only one coil will produce spark, but test results show virtually no difference between this coil and the other 2.

 

Funny. Oh well.

Try cleaning around the screw holes on the saw body the coil bolts on to with a bit of emery paper so it can earth well on the mountings not just by using the screws. Ive seen it more than once although normally on the bigger husqvarnas where bad earths fail to give spark or you get just a weak spark.

Many thanks for the advice guys. I'm still not sure if the pipe with the plastic elbow takes the oil up to the bar hole. I think it's the feed from the tank, I blew it with the air line and could see the tank bulge It is firmly in there as well, I tried to remove it a little.

 

I will see if I can remove the pump tomorrow, I suspect it is a tapered shaft according to the diagrams.

I think you may find it is the bar feed pipe. It is possible you've blown an airline in the end its gone back thru the pump and back in the tank the opposite way the oil feeds to the bar.

 

You should be able to tell If you look at page 3 on the ipl and the pipework 15/16/17/18 that's the feed pipe that takes the oil from the tank to feed into the oilpump. Find out where that goes to on the oil pump and it should be straight forward.

Is there any chance of a close up pic of the pump and bar feed hole?

Sort of thing I do !! I have started to take photos and write parts down and mount on strips of cardboard and it makes reassembly a breeze.
