Triggerhappy Posted February 14, 2018 Share Posted February 14, 2018 I'm working on an ENDT676, engine was out of framed a year ago. It developed a cracked head so we pulled it apart to fix. Found 2 sleeves that can be moved by hand. The question I have is, are the sleeves supposed to be interference fit, or how tight should they be? The block was cut for .010 over sleeves, 4 of them are tight but two move. Azny help would bed appreciated. Have had no luck so far finding what the block bore should be compared to the sleeve outer diameter. Thanks!

kscarbel2 Posted February 14, 2018 Share Posted February 14, 2018 My friend, a used TS442 manual would be superb investment, in support of your project. https://www.ebay.com/itm/Mack-Highway-Vehicle-TS-442-Service-Manual-Chassis-Components-/351086937912 Quote Link to comment https://www.bigmacktrucks.com/topic/52505-need-help-with-endt676-sleeve/#findComment-391947 Share on other sites More sharing options...
turckster Posted February 14, 2018 Share Posted February 14, 2018 The spec for liner fit in the bore is .002" loose to .001" tight. Liners moving while rotating the engine is nothing to worry about. If they do move, make sure no debris or crud gets under the liner flange.

If you are concerned clean and dri the bore , I have put a small amount of lock tight at the very bottom of the bore however I also would not be too concerned as stated 00,2 is still ok don't forget the liner will likely swell as the engine warms , It ran before it will run again! Just sayin! 2 Quote Link to comment https://www.bigmacktrucks.com/topic/52505-need-help-with-endt676-sleeve/#findComment-391997 Share on other sites More sharing options...
