Clutch arm removal

[Jimmy james]

Ok another update.

Been digging.

I will change the rubber black sleeves seen in the photo and bearing. But the metal ring at the top’of the piston seem like there is movment. Is that normal? Also where the piston is anchore to the gold looking part there is about 4 mm gap as seen in the photo. i’ am guessing it’s normal...

Getting there.
The bearings seem ok but the black sleeves are well shagged. I will changed the 4 set piece

The sleeves are called oil seals. The ring at the top of the piston is called a piston ring and yes its supposed to spin when its not compressed and there's a locating pin in the ring land for the gap in the ring. The gap at the crank where the rod rides on the bearing is equal when it gets centered in the cylinder. The gold part the piston is attached to is the connecting rod and below that is the crank shaft...your description of these parts makes me believe you have not one clue at what your looking at or doing here.

Thats just my opinion and they usually suck so don't be offended

 

[Jimmy james]

Cheers for the info. But you get me thats the main thing.

So all is sorted.

 

[Rep732]

Yep I got you... how does the bearings look? There pressed into the case halfs

 

[Jimmy james]

Thé bearing seems ok spinning normal, but full of the rubbers sleeves stuff well used the Sleeves me thinks.
I will get all new anyways

 

[Rep732]

That bearing is trashed.

not trying to sound negative mate, but your engine looks to be in a really bad way,
might be better option just getting a complete new engine ,
couple of things, is it a 2 bolt or 4 bolt engine ?
and what does the inside of the cylinder/head look like ?
looks to be more than just seal material floating around the bearings,

I also agree id start fresh with a zen engine also Its a cy engine so its ok to let it die and move to a better engine

buy a longblock from ddm

Inside the cylinder head seem ok, it was working fine until I noticed movement of the clutch arm.

I will give it a try with the new parts.

Best make sure you clean everything up really good mate.

Dude did u even clean that before the surgery, can’t let one spec of dirt scratch up ur cylinder

 

[Jimmy james]

I will give it a good clean when I put it all back together.

Im pretty sure your engine is more worried about you blowing it up then getting some sand in there

 

[szaki75]

when buying bearings make sure they’ll be C3, so clearance type.

Yea but imagine rebuilding it to just ruin it again

 

[Rep732]

I can definitely 100% see that junkie

 

[Seandonato73]

I think a long block may be in order here. Often till your done buying all the components your pretty much at long block cost. Noting your inexperience with engines this may prove to be the best option.

 

[Jimmy james]

Come on it can’t be that hard to have it super clean. iam à joiner by trade but is a new ball game. I will look into the long block.

Nah more of a time and money in vs what a complete unit costs. Your not porting it, so I just see the long block as the way to go. Just don't want to see you miss something and have to start all over again. No, it's not hard at all to put these things together. Quite simple animals really. If the cranks good, get a decent set of bearings and seals. Clean everything up real good. And slap her back together.
