All, Snap-On makes the M11-1.0 mm collet,, it is special order. (i got one) (Note; the gap of tool numbers in the Snap On list in the catalog.) Edwardo
All, I'd be willing to loan my Snap-On M11.0 1.0 mm stud puller,,,, if I can borrow a liner puller? (please?) Edwardo
Thanks sounds like a deal. I'll be making up a liner puller in the next day or 2 and as soon as I pop mine out I can sent it along.
Mark, Just checked with Bertocchi, he's a 30-year F* technician. He said that the 400 series blocks are 'half-wet' liners. They are shrunken into the blocks. To remove them they do 3 things: 0) Insert a puller down thru the cylinder, the bottom plate needs to cover the liners end (see #2). 1) Heat up the block 2) Pack the cylinder full of dry ice 3)Use the puller to pull the sleeve out. The top of the puller is a plate that sits on the studs on each side of the hole (the ones you've been removing?). Bertocchi is going try to find a picture of his puller. I didn't ask about the puller's bottom, but I expect it's like other sleeve pullers I've seen. ie: a disc with the OD just slightly less than the sleeve's OD, and a step down to the cylinder's ID to keep it centered in the cylinder.
Verell, Aren't the 2V 308s 1/2 wet too? The QVs definitely are and I though Id read the 2Vs were too??? Im going to finish connecting my exhaust fan in the shop so Lana doesnt feel the need to kill me then see is 4 or 6 heat lamps and fiberglass insulator will get the block hot enough to make a difference with the liners and studs. Im thinking I should be ably to get 350-400F out of that set-up which should make even a pressed in liner drop out.
mark, I PM'd you. I believe that 308 liners are "Wet," not half wet. We have O rings for sealing, thus, our liners shouldn't be as tight as the 400 guys. (maybe?) Edwardo
At Verell's request I have photographed the puller I divised for liner removal. The first photo is of the disc with a shoulder and a relief for the offset of each liner. The O.D. is slightly smaller than the sleeve OD and the shoulder is slightly smaller than the bore. The puller is standard Snap On issue and the inner hole of the disc is threaded to match the threads on the puller. I diagonally stradle the bore using the cylinder head studs w/nuts the secure the puller. A stack of washers or machined spacers is also needed. THE DISC ALSO RETAINS THE DRY ICE FILLING THE LINER.

Actually now that I really think about it, how does your puller work? It looks like both the plug that goes in the cylinder base and the top braket are threaded so when you turn the bolt nothing happens??? Is there maybe a custom top braket missing in the picture?
I machined a puck with a shoulder to fit the bottom of the liner, turn the block up side down, place a brass rod square on the puck, give it a huge whack with a BFH (big effing hammer) and it slips right out. I will lend you the puck, if you send me your address.
Was this 400 or a 308 they just knock out of? Thanks for the offer, but I already started machining the puller parts. I'll be ready to give it a try tomorrow or maybe Thurdays day so I have plenty of time to get some heat in the block.
Took so much force to get mine out that I had to upgrade my puller assy with a thrust bearing . . . . I think it works best to load it with the puller and then shock it with a hammer/drift . .. repeat, etc.
Washers stop the stand offs digging into block deck. Duct tape was to accomodate larger bore sleeve Bigger thread would've helped but 1/2-13 is standard milling hold downs . .. got 'r done. Other pic is my sleeve boring fixture that mounts on my lathe . .. bored and honed the sleeve in the background yesterday to check the dome cc for the latest engine build . .. aaaah . . . nirvana Image Unavailable, Please Login Image Unavailable, Please Login
The wonderous uses of duct tape never cease to amaze me.......lol My motto has always been "to accomplish a task by ANY means available", that even includes 20lb sledge hammer.
Here's creative use of a blown golf cart rear end and old battery when I ran out of fill Actually I can't take credit for this one . .. had this stuff kicking around the shop and my helper came up with it Call it "using every club in the bag". Image Unavailable, Please Login
Cool! Those studs don't stand a chance now. I've been spraying with the kroil everyday since saturday too. I wasn't really thinking the other day and posted the liner removal pics in the v12 thread. I 1/2 finished my puller then decided to just throw the engine in the press. Fast and easy. It would have been even easyier with a sesond set of hand helping, but even without it was less than an hour job and very little effort. After reading the storys of pullers and then doing it in a press, I'm sure pressing liners out is best done in a press if you have access to one.

Nice set up, me? ,, , Nope, no press yet, I have access, but I want to DIY. Hey, that's a 400 engine, or 365,,, I am working on a 308, ,,,,, is my liner i.d." smaller...? (I don't believe the 308 liners are in as tight.) Edwardo
It's a 400...what on earth would I be playing with a silly little v8 for The bore is the same on the 400 and 308, 81mm
That would be cool, but no. It becoming a 5.5 liter and going in the 308, how did you miss this thread? http://www.ferrarichat.com/forum/showthread.php?t=170171
