headdamage Posted March 4, 2008 Share Posted March 4, 2008 I've just taken the bearings out of a disco 200tdi engine and I can't find the numbers in the books. Any idea what the new numbers for these are? - Big ends are ERC8841 - Top of mains is ERC8839 - Bottom of mains is ETC6422 Why are the tops and bottoms of the mains different numbers? I thought they should be the same. Thanks for any help. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted March 4, 2008 Share Posted March 4, 2008 They are different part numbers because the two shell halves are different and the one nearest the flywheel is wider - They usually come in a set anyway (that's how I got mine). The part number will depend what size they are. To match them up - look on the back of the old shells to see the part number. Les. Quote Link to comment Share on other sites More sharing options...

headdamage Posted March 4, 2008 Author Share Posted March 4, 2008 Thanks guys... I thought it might be due to the physical difference between the upper and lower halfs but wanted to be sure. I'm used to engines where the upper and lower are the same like the 2.5na. Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted March 4, 2008 Share Posted March 4, 2008 The numbers stamped on the shells are the individual shell numbers, the parts book will show the numbers for complete sets. Mains RTC4783 standard. Mains RTC478310 .010" undersize. Big ends RTC2993 standard. Big ends RTC299310 .010"undersize. Thrust washers RTC2825 standard. Thrust washers 538131 .0025" oversize. Thrust washers 538132 .005" oversize. Thrust washers 538134 .010" oversize. Quote Link to comment Share on other sites More sharing options...
