Repairing a 394 saw case

[Brewz]

Hi Folks.
Looks like I have picked up a rebuild job on a 394.
Owner tells me there is a hole in the oil tank where the dog has rubbed through.
Apparently JB Weld works for a while but does not last.

Has anyone got any tips on repairing a hole in a case half...... or a decent clutch side 394 case half they would part with?

Cheers

Only have a good flywheel side to spare

Could you do JB weld and put a stand-off under the dog so that it can't rub the case any longer?

It might be tough since it was already JB welded, but may be worth a shot. The case half would be the right way obviously.

Have it TIG'd and re-drill/tap.

I dont have it yet, but my assumption is that if it keeps rubbing through, there is no bolt holding the dog off the case.

I wont make any plans untill I have it but just thought I would put out a feeler for repair techniques (TIG weld???) or the preferable option of a better case half.

The 394 clutch is working wonders on the 2100

A skilled welder can fix it.

Actually worked out it was from a partner k950 concrete saw

Its sounding like welding is going to be the best bet.

Depending on location, round hole out and use an interference fit grommet?

I've welded damage like that before. Hopefully you can find someone in the down under that can weld it up.

I have been lied too

Fits perfect though and looks good after a good tumble in my case cleaner and 3 new springs
It certainly takes up every bit of available space in the 395 clutch drum

A grommet?

Duct tape?

Partner k950, jonsered 2095 are based on the 394/5 for want of a better description. Though cylinders are same for k950 & 2095 but 395 has a different footprint.

A grommet?

Duct tape?

A grommet. As in an insert made of rubber, metal etc. Perhaps even a plain old rivet. Like I said very location dependant.

Dammit! Like a welsh plug. That's the example that escaped from me.

A grommet?

Duct tape?

Maybe in the big woods as a temp fix yes.

end of story

I do repairs fir a hobby/pocket money and like to do stuff properly, hence why I asked.

The owner or the saw has been bogging up the hole but I don't like using putty for much more that thread repair on non load bearing screws or filling pitting in on a case or chain cover.

I have a mate with a Tig, but just thought I would ask the question

I have a MS 200T case in my friends welding shop now I can post some pics of the repairs he does some good work. It has a hole in the oil tank and a broken mount.

Myself, I would try and source a good used case half... Tig welding would be my second choice.

Sorry I don't have one to sell, or I would.
