MF135 Restoration #12 Fitting the Liners

[Music] well we're gonna try and drop some liners you know I've got one in there not all that tight a fit which is a good thing look at that that's nearly too loose but we've locked tight at them all in so that's okay we've washed the block took me bloodier ages took a fair was very dirty no we fitted the liners so we have them in the other side they're the I probably would have liked to see the line as a little bit tighter than they are but I'll just read anything I was doing a bit of research on it and they said the new linings a liners or more of a slip fit than the old press fit runs so anyway they're not moving they're all locked hide it in and everything yeah I would like to see them tighter like I say but they're all 680 locked hide it in all the way down so there's no chance of a moving or anything like that and we have a slight protrusion on the top here so you can feel that you can feel that the line is it just proud of the block now what happens sometimes people deck the block here they machine the top off it and when you put the new liners in the liners stick up too high I can't remember the exact measurement I will look it up probably but look that's okay I've gone across here with a wire brush and off of D bird and I've used a little buffing tool around the water jackets and all that so maybe now it looks a little stained it's it's nice and flat right I have the liners in and I I only have one a little bit of a clip where I pushed a line or in and my cameras point up the zooms plane up so anyway there's they're winning a bit too easy and I thought well in the past you don't know you know when you get the old line as our people in the past these are a press fit liner and you've put ice in them you heated the block up and they're actually a bit of a struggle to get in at times some let me I've had people break them and getting them in and they're quite a bit of an effort so you don't know what's been done to a block before you come along so I've got these new liners here and dry I couldn't get him in but with a little bit of oil or Loctite on him I could actually press it in with my hand which in my opinion is a little bit too loose so well it's looser than I've done in the past and so anyway I've got under the engine people and we've had a chat and they said that the the aftermarket liners nowadays even through perkins they're not pressed fit anymore they're actually doing him a slip fit and they're a bit of paper they gave me problem with these engines can occur if cares not exercised when fitting replacement liners many years ago the tolerance of replacement liners was changed to provide a slip fit rather than an interference fit in this little cylinder block although this is turned slip fit liners are ground to an extremely fine tolerance tariffs are sorry to provide a rather tighter slipped fit well I didn't feel mine were tight and so I followed up on that and look we're okay someone at some stage has honed this block before they put the other liners in and I felt it was too loose my liners so where the yarn about and well I've agreed to do as I've actually 680 locked I did the line as the full-length so they've been locked tided from one end to the other full-length and that takes up door knowing that aches up a fair bit anyway and and I've often put Loctite on them because if this if this little groove the the little recess where the liner sits on the top there is slightly up or slightly down well the liners can break around the top ring there around the flange and what they're known to do is they just slam the liner down into the sump and these flames line is aren't so bad some of the early Perkins stuff they didn't have a flange line it was just a press fit liner now with these flames liners they've gone to a slick fit but I believe my blocks been honed at some stage and it's a bit loose it's not what I would have really liked but with a full complement of 680 Loctite all the way it'll be fine yeah and even if something cracked or broke up here there's no chance of the bottom of my liner actually going down into the sump so what I'm what we're over here to show you is line of protrusion and I've just been through the book the Perkins the genuine Massey Ferguson Perkins book and I couldn't actually find an exact figure for this but he's up there I know I looked it feels great to me but I just thought I would show how we measure it and I've got this little gauge I made and this was just an inch by inch block of aluminium bar aluminum if you're an American bar and I cut a piece out drill the 8 millimeter hole in put a slot in it and that allows me to put a digital dial gauge in so that you can read what I'm doing so the idea is when you get it over to the side here just zero it so you're on the side and then you bring it forward up under the liner and so I've got to see our line of protrusion there that's great really then I can come around here and do the same I don't know if you can read it here and come along on the back here now that's just on - just follow here make sure he's on the zero it's on half zero again they touch you these digital meters 2.5 there so we're all are we starting on - it must have moved it again look to Farley that's three three and you were starting at half of this that's three so yeah that's how we do that bit that's right and the idea is to have these reasonably level all the way you know this one I know you can't read that that's two again so we're fairly even we're well was it my well we was in half a fair over the whole lot and that's important so the firing on the head gasket sits down and you haven't got a high liner you know taking all the load then the one next door's do enough and sideburns a head gasket through so mm that's great you've got a wet sleeve lining you'd be looking for that same thing the head will go down and clamp and when I push these liners if I put a steel plate there give them a bit of a bump just to make sure though right home so we're happy with that [Music] you
