case ck engine tear down

[tom sullivan]

I am dismanteling my 430 ck engine to be rebuilt, gas engine I believe 149 cu, how does the front crank pulley come off to get the timing cover off my goal is to strip the block down have it boiled, magnafluxed,then rebuilt on the front center there is a squire drive "nut" is it right or left hand threads thanks

Tom, That square drive is the nut, it is a RH thread and sometimes they are very hard to break loose. I have had to heat them red hot on rare occassion. How soon will you have the sleeves out of that block? I would like the measurements of the outside of the sleeves for an engine project in the near future. If you or any one has those specs Would you please post them for me!! mEl

Do you want an old sleeve? Send me an email. Lee

Vac, The reason I want the dimensions is that the detailed spec sheet that I got from Case with block dinensions show that the 148-159 share common bores for the upper counterbore, upper pilot and the lower coun terbore, if this were correct the 159 sleeves would be a drop in for a 148 block. I do not believe that the detailed spec sheet is correct so I wanted to get the exact dimensions off a used sleeve to compare and correct my info. I do not want a sleeve to use. If you have or have access to a dial caliper a quick measurement of those areas I previously mentioned would be appreciated. Thank you for your trouble if you do. mEl

I was offering one so you would have it to measure. The VA, 200b, 148, and 148b engines share the same outside sleeve/block bore dimensions.
Upper flange 3.912 x .250
Upper body pilot 3.778
Lower body pilot 3.718

I do appreciate the offer, but you have given me everything I need without the shipping! I will compare this with the dimensions given in Case's detailed dimensional data sheet which I feel is incorrect as it gives identical data for the 159!! You have been so helpful and I do so appreciate it, thank you again. I did put a 148 kit in a VAC years ago, it was a leftover M&W I believe and although the pistons were down in the bore the increase in displacement still gave me a 26 HP VAC, not bad. mEl

Mel, Several years ago I bought a used 148 for my 300 it ha a 3-7/16 kit in it but was worn bad I checked with napa shop here and they found that continental used a piston that size with same pin and pin to top distance 20,40,or 60 over available, so I had them bore the sleeves 20 over and put those pistons in I did not trust going 60 over because I thought sleeves would get to thin at orings. Should be about 155ci makes 46hp@540 just my experience. wouldn't mind talking my emails open, Jim H.
