Mep-002a shakes is this normal?

[dstang97]

Got a mep-002 a while ago and I was wondering if it is normal for the genset to shake. Its bad enough where it is hard to read the gauges up close. All of the isolators look good. I also removed the covers and ran the genset to watch the blower and it looked fine. So how bad does yours shake or move?

 

[dstang97]

All filters and oil were just done, everything looked good. ~700 hours.

short answer...they shake, rattle but don't roll...hopefully.

It's only a 2 cylinder, the more cylinders the smoother the engine

Is it hitting on both cylinders? One dead cylinder will make a good shaker. Check exhaust temp at the ports to find out.

its hard for me to compare I have not really seen any others run.

 

[phil2968]

Get a infrared thermometer to check it out.

where would be the best place to shoot it at?

 

[phil2968]

Right where the exhaust bolts to the head. Or where it comes out of the shrouding.

 

[dstang97]

wouldn't a dead cylinder create a lot of smoke unburnt fuel?

 

[phil2968]

Not if it is not injecting fuel.

dstang97,

There's discussion of this same vibration problem in this thread. Maybe something there will give you some ideas. Seems to be a common problem with no sure cure.

Where do you have the set mounted? If you have it on the garage floor try standing on the ends and see if it rocks at all side to side, end to end. If you have it sitting on concrete or asphalt try moving it to a different spot. Try putting it on a level part of your lawn. I had one that would vibrate so bad you couldn't read the hertz meter, put it on the lawn and was fine. Then I bolted it down on the trailer and it seems ok there also.

I have it mounted on a m116a2

all the 002s ive had shook quiet a bit, nature of the beast. you can tweek the valve adjustment and inj. pump timming. also check the isolator mounts on the control box ive replaced these before. be sure both cyl. are hitting.
