TWJM Posted February 25, 2015 Share Posted February 25, 2015 Hi, let me start that I'm new to this....I have a question on liner installation. How tight are the liners supposed to be when installing?? We are using a 5# plastic dead blow hammer and they seem to be awfully tight....is this normal?? The manual never said to lube the upper portion, that seems to be where it is really tight (last inch). We beat and beat, about .010 difference between 3 cylinders....ran out of time. I'm assuming after the silicone sets that you would not want to disturb it "try and knock the liner down a little more the next day"?? Are you supposed to lube or has anyone had this happen to them? Deck height seems to be a little high also but wouldn't the liner only go so far down anyways?Any help would be appreciated. Thanks!!

br549 Posted February 25, 2015 Share Posted February 25, 2015 We put them in with a bottom rubber spring pad and a small sledge hammer. You could put in freeze and they go in easier. I would want them to be bottom out before the silicone set's up. I think you need a bigger hammer.

TWJM Posted February 25, 2015 Author Share Posted February 25, 2015 So, since I have 3 already installed that need to be adjusted a little more...silicone is set up now, be wise to pull liners back out or tap down a little more?? Has anyone done that and is it ok to use some lube to install??

TRH Posted March 6, 2015 Share Posted March 6, 2015 Exclusively use coolant (I believe? Check manual if you need me too) to lube them for install. They don't like incompatible fluids and will cause the seals to swell and make them goddamned near impossible to install.I don't remember silicone being involved but it's been awhile since I was that deep in an e7, too busy with MP8s 1 Quote Link to comment https://www.bigmacktrucks.com/topic/39064-1997-mack-ch613-e7-cylinder-liner-help/#findComment-281642 Share on other sites More sharing options...
