TR2/3/3A Help!! how do I get the liners out of a TR3 eng.?

Share this page

Hey Stig,....don't want to Hijack the thread, but when watching "Top Gear" the other evening couldn't help but notice your girlfriend in the background. It was hard to get past the bikini, but I saw nothing to indicate a need to cover her face with a helmet.
Are you REALLY Martin Brundle?
Take care Bob

I got out my three pound sledge and a long drift and started hammering. If you are replacing the sleeves, don't worry about damaging the side. Try to loosen each side. They will come out especially using the 3lb sledge. I did this with the engine still in the car. Had to get it high enough to use the hammer.

Has anyone ever tried filling the cylinder with dry ice and shrinking the thing out? And, no I'm not Martin Brundle (nice guess)....the mystery continues!

That might help, but I would try jacking them out from the bottom with the fat girl first. Just turn her crank until you get a clear shot. You might try some solvent too because it sounds like they are not rust in, but the glue from the permatex or whatever was used is holding them in. I would get all the water out and put the solvent in from the top. You might have to use some strong stuff like lacquer thinner, so watch out for the paint job.

I went to my buddy's machine shop to make a tool, but the machines are set up for a job he is doing. I'll have to wait a week. In the meantime I looked more carefully at the crank throws and its not good. The combination of oil, antifreeze and water wetter have turned beautifully polished crank throws into something resembling the grooves on a 45. (ancient music storage device). So on my way home I picked up a cherry picker and am now in the process of clearing some space in the spare bedroom to store car parts.

Nice looking car Stig. I knew you couldn't be Martin Brundle - he works for ITV not the BBC!
 
Re: Help!! how do I get the liners out of a TR3 en

So that's sittin' over in O-town, huh?

I'll be over on Friday afternoon. :smile:



I'm for genteel persuasion. Too easy to nick/scar the block bores the sleeves fit into. Just my penchant for trying to ~not introduce~ more problems.

This sounds to be turning into a BIG case of the "might as wells". But the car looks to deserve the proper (complete) treatment.
 
Re: Help!! how do I get the liners out of a TR3 en

What is a crank throw? Are you sure that it needs to come completely apart? If the motor has such short time on it, I would make sure. It is a tractor.

The lumps th' rods 'n mains are attached to. He's referrin' to the shiny bits where the babbetting touches.

Groovy!

Can’t you just get a little fat girl to sit on the bumper and then put a floor jack with 4x4 on the sleeve and jack them out from the bottom?
Click to expand...
The exposed lip of the sleeve is very thin (especially if you have the 87mm liners, even more so with 89mm). It will just cut into wood, rather than forcing the sleeve through the block.

Don't have to pull the liners to remove the crank ... but as long as you're in there ...

My brother came over to give me a hard time. and with a little chiding...THEY'RE OUT!!!

With th' mill in situ you've done remarkably well. What's th' plan for th' crank?
 
Re: Help!! how do I get the liners out of a TR3 en

The bearings took the brunt of the abuse. The center journals are still perfect. Number 1 and 4 show a very slight scratch. I think at this point a set of bearings from BPNW will do fine. Since I couldn't on a lathe or mill to make a tool, I drifted the liners out. The process caused a small amount of chipping at the bottom of the liners. They are .040 over and a bit thin at the bottom. It looks like I can remove 1 or 2 hundred thousandths from the bottom of the liner to clean up the damage and still be able to reuse the liners. I cannot believe that little bit of shortening would cause piston binding (l over d). Also, I removed the lifters, the cam is fine but 1 of the new lifters obviously was not hard enough, starting to mushroom. also a couple of others were not rotating. I think some of these aftermarket lifters are of dubious construction/quality.

One more thing, I miked the figure 8 gasket at .016". I have several gasket sets around and all the gaskets are .016". Is there a source for some .020" figure 8's?
 
Re: Help!! how do I get the liners out of a TR3 en

The chipping is why I made a brass-tipped drift

Mordy can make fig-8 gaskets almost any thickness you want :

Not sure of the price, tho, since I opted to go a different route (adding fire rings to the head gasket). Also make sure you really need that extra .004", as too much is almost as bad as too little (oil & coolant leaks).

The lifter problem is well known; the only solution seems to be to have all new lifters tested for hardness. Someone posted to another list that all the lifters they got from BPNW were hard enough, but I'd still have them tested.
 
Re: Help!! how do I get the liners out of a TR3 en

What about these hot-rod lifters that are shortened a drilled? Are they of better quality?

I'd pass.
Hap posted a lifter source here recently. Search "Rockwell tested lifters"

APT was the source.
 
Re: Help!! how do I get the liners out of a TR3 en

Went to APT website, they only list lifters for spits and 6's.
