Installing sleeves in a M Crawler

[JACK V]

I would greatly appreciate it if someone could give me some Pointers on installing sleeves In my 1938 M crawler.

Do I need any type of sealer around the two O-rings? And if so what type ?

Also do I install them flush with the block or let them prtrude slightly ?

Take care and Have a Great Weekend

you wire brush the block were the orings and top of the sleeve set--- over and over. THen take the sleeve and set it in the hole without the o-rings. It should basically drop in the hole. IF not, wire brush more. AFter everything fits, you put the o-rings on the sleeve, put a little soap or vegetable oil on them and "push" them in the hole. Dont twist, just push. THE sleeve will s tick up a few thousands and the head gasket will crunch it down and seal. I put a very small bead of RTV inder the top lip of the sleeve prior to install. Some do this, some dont.

You need to make sure that area where your o-rings are installed needs to be thorouly cleaned.
If there's a counter bored area at the top of the block where the sleeve sits it need to be cleaned too. I don't have a manual on your tractor, but I see some of these wet sleeves protrude from .003" to .007" above the block. You should check your manual to see what it recommends. Hal

In my manual it doesn't give a height, just says the sleeve will be slightly higher than the block.
