Gentles,

Another rainy day!

Went to get injection pump and the injector from Bosch lab. This time payed only with friendship.

Sorting bits from basket, had take measure to the small end bush, and it indicates about 0,15 mm of lash on vertical axis. Let's see if new bush will be needed.

2 pics to the show.

Gentles,

The CD got it kart to move side to side to be erected.

Passed tap on threads to tuning them.

Found some sand pockets in the crankcase... ence they paint it with filler.

Give a very fine paper sand (2000 and 5000) at big end.

And found a original stamp on top of crankcase.

A dew pics to the show.

Original Lister Cs Engines / Lister CD - Iron down to rebuild
« on: April 25, 2025, 03:26:35 AM »
Gentles,

The kart is free of the CD.

All iron is downtown to start rebuild.

Last bit of crankcase was the liner, and it ends up to be a smooth operation.

A few pics to show off.

Gentles, AdeV

I use MS Picture manager with win7 64.

Giving one more push to the CD, today put my eye in the oil pump.

But going back a few days ago I was suspicious about the shape of pinion teeth. They seem to have chewed "something" at any time of its life.

Looking at the intermediate oil pump pinion, and the oil pump pinion it self, for sure something got to be there between the teeths.

And also I noticed the pump pinion was wobbling on its spindle, and take out the tapered key. Take a look at it. Just incredible!

Take a look too to the oil pump wheels teeth's shape and you can imagine how many thousands of hours it has.

A few pics to the show.

Gentles,

The CD is almost striped and so some bits already got one hand of primary paint.

In the other hand started to search for some parts: Rocker bushes, crank oil seals, governor bearing.

Made an inquiry about main bush bearings, and valve guides, but nothing so far.

Meanwhile, start to prepare bits and store in baskets.

Push out the crank oil seals, and surprise - at anytime of engine life they put a metric oil seal, hence why they have a wrap of tin foil, because casing is imperial (2.3/8x3.3/8x1/2). But you can see they put in M 60x85x12.

A few pics to the show.

Cheers.

Gentles,

While raining outside and after supper, give a few more kicks in the CD.

Flipped to side, finally toke oil pump off, after that the sump - take a look at that gunk and slurry!

Pull out long head studs and crank after that.

Intermediate gear of oil pump too, and crankcase support brackets.

Almost all stripped. Next task pull off compression operating shaft.

A few pic to showoff.

PS: Please can anyone tell me why crank casting date - following Lister's mode of dating cast iron - shows 15JAN1920, but CD only start to be made at 1933.

Gentles,

Another trick to pull off crank pinion.

Got to make extenders to my ugly puller. It ends perfect as I wanted.

Pulled out woodruff key too.

Now got to take out long head studs that goes from top to bottom.

A few pic to the show.

PS: I give up! even pulling out EXIF data, no joy to show the straight pic.

Gentles,

The toy is going slowly.

Today managed to drill and tap M5 hole to put a set screw in order to prevent or stop(??) the bearing to spin inside its housing.

Remember I pulled easily the bearing?

Lets see how it goes.

This trick was - once again - one advice of my friend Mr. Pedro, from VEICOMER (https://listerengine.com/smf/index.php?topic=9555.msg111186#msg111186)

PS: image without properties still rotate.

AdeV, Gentles

Many thanks for your time, and stubbornness (bien entendu!).

The catch is: Before was all ok! why change what was ok? (nº 1 rule of computer science engineering - my humble degree).

But, I can see you are at Linux (was there 20 years ago), so Ill follow your lead. 1st rule here is to share good info with our forum members.

Keep the good work! Covid took us a few Master minds of stationary engines.

Gentles,

More than 150 days,  in 4 mouths, of rain makes everything idle here.

A few roof edge tiles fell down with Martin's storm.

Meanwhile, a few more bits off the Lister CD. All wheels of kart are finally off.

And a new  ;D ;D (2nd hand from 80's) field cultivator to my micro farm.

2 pics to the rant.

Cheers

AdeV,

Indeed!

But there some pics (above) that the thumbnail now is horizontal because I edited the image and rotated it -90º, and so when you click it the resize will show it as I intended to be seen.

I mean I cheated the resize tool in order the pic be shown "right".

See below pic showed with the hint on original, and after in the one edited.

Many thanks for your replays.

When I say autorotate it can be anything that the software used manipulates an image to change original post.

AdeV, I underline I got the most respect to you and the outstanding work you do supporting this forum - Peter & Rita Forbes just disappear because there was no redundancy.

You can see my all images got 800px max wide, in order to to avoid any horizontal scrolling.

Yes, please disable the resize, because when image "rotates" the detail of image will be harder to get after reading the sentence that pin points it.

Bronco, my images are all edited before upload - there is none upload raw, neither the attachments allow such size.

Just my 5 cents for the improvement.

Cam shaft is out, but stupidity stoke again.

Forgot the gear wheel have taper pin AND woodruff key. So hammer drove woodruff key agaist cam bushing.

2 pics to remember.

Meanwhile exhaust is clean and painted, fuel tank dents are straightened, and rings out of piston.

Cheers
VP

PS: DAMN AUTOROTATE!

Gentles,

Started do note measures about wearing to see how bad thing can go.

Already told outer #1 bushing  - that I suspect it spun inside crankcase end cover. See dimensions at pics 1 and 2.

Pic 3 and 4 the #2 outer bushing and crank journal.

And 5 and 6 the the #1 bushing ID and crank journal.

More....
