Ms 291

[Mark_Skyland]

A customer brought a bit of a battered 291 in a couple of weeks ago with an issue. I had a chance to look at it this week, I think he's had his moneys worth out of the clutch drum to say the least.

 

It was a bit of a job to get he drum off as it had ripped to bits and was well and truly jammed up in the cashing and the brake band. This was the state of it.

 

 

 

The big problem was getting the clutch off, the drum had taken the end of the worm wheel spring so tit had to come off. I usually just use an impact wrench to whizz clutches off but his time it was having none of it. I tried penetrating fluid which didn't help then tried the old piston stop and big socket bar and that didn't move it so I tried a windy gun and still nothing! The only options I thought about where to cut it off with a grinder or give it some heat. These machines are just made of plastic, plastic pump, plastic casing etc. I gave the heat a go to save the clutch but not loads of heat and it actually worked, usually you have to heat stuff up to cherry red to get them to move but I think the oil from the day before may have helped. I still had to wind the air gun up but it did pop off first spin.

 

Not got it back together yet as we didn't have the worm wheel in stock but it should be up and running next week.

 

If I come accross this issue again I think I will tap one of the mechanics up in the next unit for their snap on wrench.
