JimAttrill Posted January 27, 2007 Share Posted January 27, 2007 I read or heard somewhere that it is not possible to get the pistons out of a 200tdi Disco because it is not possible to get the ladder frame off with the engine in. Is this true? Quote Link to comment Share on other sites More sharing options...
Edd Posted January 27, 2007 Share Posted January 27, 2007 I read or heard somewhere that it is not possible to get the pistons out of a 200tdi Disco because it is not possible to get the ladder frame off with the engine in. Is this true? yes unfortunatly. The ladder frame prevents acces to the bottom of the engine and can only be removed by taking the flywheel housing off the engine to get to two bolts that run horivontaly into the back of the frame.

HTH Edd Edd, that is definitely no so on a 200Tdi disco as i have repistoned mine with the engine & box in situ. Quote Link to comment Share on other sites More sharing options...
Andy Posted January 28, 2007 Share Posted January 28, 2007 id always heard you couldnt get the pistons out of a 200tdi in situ as well. thats great news if you can Phil as i need to do mine. i was lead to believe its possible on a 300 but not a 200.

Les Henson Posted January 28, 2007 Share Posted January 28, 2007 I heard the same - you can do it on a 300, but not the 200 with the engine still on the box. Les. Edited after looking in the Haynes manual (yeah I know). 'Repair operations possible with the engine in the vehicle' a ) Removal and refitting of the valve operating (rocker) gear. b ) Removal and refitting of the cylinder head. c ) Removal and refitting of the timing chain/belt and sprockets. d ) Removal and refitting of the sump. e ) Removal and refitting of the big-end bearings, connecting rods, and pistons *. f ) Removal and refitting of the oil pump. g ) Renewal of the engine mountings h ) Removal and refitting of the flywheel. Note that the operation marked with an asterisk can be carried out with the engine in the vehicle (after removal of the sump), it is preferable for the engine to removed, in the interests of cleanliness and improved access. Note that, while it may be possible physically to overhaul items such as the piston/connecting rod assemblies while the engine is in the vehicle, this is not recommended. Such tasks are usually not carried out as seperate operations. Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted January 28, 2007 Author Share Posted January 28, 2007 'separate' is considered better . Thanks Les. So where does this common story come from that it is not possible? It is all very strange.... Quote Link to comment Share on other sites More sharing options...
Les Henson Posted January 28, 2007 Share Posted January 28, 2007 I really don't know Jim. I've removed the pistons on all the oil burner L/R engines with the exception of the 200TDi engine, so I really don't know for sure. I have to strip and rebuild a disco 200TDi engine within a week or so, so I will know for sure then. Les. Quote Link to comment Share on other sites More sharing options...
LR90 Posted January 28, 2007 Share Posted January 28, 2007 Les, read that carefully. It implies you can change the pistons with the engine in place, but perhaps only with the gearbox removed? Quote Link to comment Share on other sites More sharing options...
Andy Posted January 29, 2007 Share Posted January 29, 2007 well i look forward to the excellent tech thread thats bound to show us once & for all if its possible Les. Quote Link to comment Share on other sites More sharing options...

Andy Posted January 29, 2007 Share Posted January 29, 2007 i believe you Phil, just had always heard otherwise. plus ive never taken the pistons out of an engine ive wanted to run again so it'd be handy to have a nice picture rich guide to follow to make sure i dont do anything really dumb.

Phil Hancock Posted January 30, 2007 Share Posted January 30, 2007 i believe you Phil, just had always heard otherwise. plus ive never taken the pistons out of an engine ive wanted to run again so it'd be handy to have a nice picture rich guide to follow to make sure i dont do anything really dumb. Andy, sorry cant help on the photos, it was just another spanner session on an engine at the time, so i didnt bother with the camera. Also i was well cheesed off as i should have been in Norfolk on holiday but due to a strange missfire ended up doing the pistons, couldnt use the 109 either as the RH dumb iron had sheared off and i only found that out when checking the oil levels to go to Norfolk! So it seems like you have another job, involving a camera, when you do yours. Quote Link to comment Share on other sites More sharing options...
Tonk Posted January 31, 2007 Share Posted January 31, 2007 on a defender 200 there are bolts on the inside of the bellhousing which bolt into the back of the ladder frame, on a disco engine they bolt through the bell housing aswell, so i know that u cant on a defender engine but i see no reason why u shouldn't be able to on a disco 200 engine Quote Link to comment Share on other sites More sharing options...
Andy Posted January 31, 2007 Share Posted January 31, 2007 ahh cheers for that Tonk, could well explain the different answers. i'll find out this year, i just keep putting the job off currently. my last tank of fuel in the disco has lasted a month, driven it twice since i got a motorbike & no real intention to drive the truck again unless i have too.

JimAttrill Posted February 3, 2007 Author Share Posted February 3, 2007 Oh well, I don't really have to know now, because the problem with this motor was completely stuffed valves and guides at 170k kms, so a head job has fixed it. Quote Link to comment Share on other sites More sharing options...
