Installing the Sleeves

The cylinder sleeves in my 4A are coming out with light tapping from the bottom, using a brass drift.

How hard is it to fit new ones back down in?

I've been slamming them down with a five pound contractor's grade yard hammer from Grainger, and they're still not moving much. I missed once and hit the block.

OK, not really. I'm just gently tapping them down by using a piece of hard oak as a buffer. Any other suggestions--it's getting tight. I keep fearing I'll realize I'm an amateur.
 
Should tap in easily. The hard oak should do quite well. I generally use a brass hammer, but it doesn't (shouldn't) take much, just gentle taps.

The liners are pretty tough. As long as you don't hit them with hardened metal (like a steel hammer or drift), they aren't likely to break. I've beat on them with my brass-faced "liner punch" (length of 1" water pipe with a brass cap on one end) plus a BFH and never chipped or broken one. But that's only to get them out, they should go in much easier.
 
when I get this all back together I'll soak up the bearings and cam with cam lube and turn the motor over without spark to make sure things get really lubricated.

I suppose my oil pump won't register until I'm up and running.

I've noticed two imperfections I'll ignore. Piston No. 1 crank pin is scored slightly due to junk in the bearing. I'm putting new bearings on. One cam lobe has a scratch I can feel with a finger nail.

Any suggestions on startup precautions? Would you pull the cam over that scratch--or just to have it checked?

If you leave the plugs out, you can spin it with the starter and see the oil pressure come up. Not really necessary, but might give some peace of mind.<div class="ubbcode-block"><div class="ubbcode-header">Quote:]One cam lobe has a scratch I can feel with a finger nail.

Would you pull the cam over that scratch--or just to have it checked? [/QUOTE]Depends a little on where the scratch is and how it got there. If it's on the peak of a valve lobe, then chances are that it will get worse fairly quickly. Meaning I wouldn't put it back together that way unless I wanted to just drive another month or two and then pull it.
But anywhere else probably won't be a problem.
 
When I re-built the engine in my 1958 TR3A last spring, I put the figure of 8 seals into place and the liners dropped right down to the corner stop. I didn't need to do any banging, thumping or whatever. They sealed nicely and since then I've driven about 6,000 miles without any issues. Except for the ethanol issue, but that's another topic.
