1100G low compression, burns oil.

[Redman]

I have today and tommorow to
make good progress on this……. Before other things are going to limit my time to
work on it….

started on it this morning….

realized that still had base gasket stuck to bottom of cylinders.
That took some time. Putty knifes I had were not getting it, even when sharpened.
So got a utility blade scrapper.
Okay, that better. But coming up in small pieces

Next: Onto putting pistons back on conrods. . . . .

oh, man,
big setback

dropped wrist pin into crankcase

Pics later……

Quick update: found it. Retrieved it.

so, that was a days delay, of the two days I had to work on this.
and now have more parts to
order (pan gasket, shift detention spring) and scope of work expanded (reinstall pan, reassemble exhaust).

Have updated the "dropped pin into crankcase" thread with details of finding and retrieving the pin.

Now to continue with the reassembly of engine

Once you retrieve it be sure to stuff shop rags around every hole including the one your working on. prevent the retainer clips from falling in also

Yep, not just a cloth laying there like I had before.

Hey, Okay Chuck, you mean like this

har har har

Got all four pistons on.

Got base gasket and tear drop orings on. Got the dowel pins in place.
Devised a way to suspend cylinder block in position (one tiedown strap around it, on from one end, up and over frame to other end).
Have 2 & 3 up higher. Devised a way to hold 2 & 3 piston level. (split 1x2 under piston)
Abandoned the soup can ring compressor idea. Just used hose clamps (cut off excess length so easier to remove)

Lowering cyclinder down and lining up the 2 &3 pistons was difficult. A lot of fussing with the rings.
Took a lot of fussing to get the rings started in the clyinder, and was difficult to lower cylinders.
After a while I realised the cam chain and the tensioner giude were tangled up in the cam chain tunnel. Doah, tensioner giude was infront of the chain, doah. CAn kinda see that in this pic (and the start of it in above pic). Could not get it straightned out.

.
Had to lift cylinder up to get cam chain and tensioner giude back in order. Drat.
THought I would be smart and hold the tensioner guide back with a bungie cord.
HAd to start over with getting 2 & 3 piston lined up, fuss with rings. HAd to keep a close eye on front of piston and back of piston to see that was level. Got 2 & 3 in cylinder after lots of fussing.

Had problem lowering cylinder any further. Could not figure out why, THought maybe one of 2 or 3 rings jammed or something.
Took me a while to notice that the top of tensioner guide was stuck into the tensioner hole, doah. So that bungie cord idea wasnt so good. Took it off. Had to lift up the cyclinder a bit to get the tensioner guide out of the tensioner hole.
Then I figured out that the wire I used to tie up the cam chain should have been a lot further forward on the frame, to hold the chain more forward, that would have avoided these couple problems with the tensioner guide.

Got the cylinder down just a little lower, then position crank to get 1 & 4 piston in position. A lot of fussing with those rings. But with the experience of 2 & 3 I knew to watch that the pistons were level by looking at the front and compare to back, and knew better what to look for with the ring compressor clamp. GOt 1 & 4 in a little bit easier than 2 & 3, only a little bit, still a lot of fussing and aggravation.

Here is cylinder in place.
And Me saying "There, I never want to do that again. I NEAA-VEEER want to see piston rings again."

I have seen my piston rings when I was 19 (Sunbeam Imp) and now that am almost 69, and dont want to see any of my piston rings ever again.

Note: I do not post this as a tutorial for anybody to follow. (But maybe somebody might benefit from me discovering my ignorance.)
Am posting this mostly as a story, and will have questions.

Great job! Keep going, it's all going to be worth it!

 

[Redman]

With cylinders on. And cylinders oiled. And if I hold the cam chain so doesnt bunch up, I can turn the crank (clockwize) with a wrench real easy, see pistons going up and down. But I hear little "sshhhh" sound. I assume that is new rings "seating in".
It turns easy, doesnt really coast along after I let off.

I hesitate to ask, but:
What do any of you experienced engine rebuilders say ? ?

 

[Nessism]

Sounds normal. There should be some sound of friction, since the rings are spring loaded to push out into the cylinder walls. In actual use combustion pressure pushes the rings into the cylinder walls (excepting the oil ring.)

Looking good Dave!
