nickr Posted August 12, 2012 Share Posted August 12, 2012 Can I just check a couple of points. Looking at the official manual, A proper tools is used to set the depth of the seal. Without the tool how far should the oil seal be pressed in. I'm assuming to the bottom of the flywheel housing? Also the manual shows the plastic installation sleeve being remove from the seal and placed on the end of the crankshaft and then the flywheel housing being offered up to it. This is correct isnt it?... I dont know why I thought last time i did one the sleeve stayed on the flywheel side of the housing? Thanks Nick Quote Link to comment Share on other sites More sharing options...
western Posted August 12, 2012 Share Posted August 12, 2012 the plastic sleeve should be removed before the seal is fitted, it's only to ensure the seal keeps it's circular form. as per the book for fitting if no special tool, drive seal to bottom of location.

Eightpot Posted August 12, 2012 Share Posted August 12, 2012 I thought the plastic sleeve was to stop the seal getting damaged while sliding onto the crank? I did one last week and there was no way I could get the seal over the crank nose without deforming it without using the plastic sleeve. That said, I couldn't get it over with the sleeve provided with the Bearmach oil seal either, but it slipped on easily with the sleeve I had from a Britpart 300tdi oil seal. Is that just me being overly sensitive though?? I was under the impression you had to be really careful with the seal lip or it will leak if you so much as touch it.

ejparrott Posted August 12, 2012 Share Posted August 12, 2012 Kettle's new seal came with a fitting sleeve and I fitted that over the crank with the sleeve, which was then discarded. I did however notice that there was something in the back, but not having the time to investigate further I left it there on the basis of it was working before! Should it have been there...whatever it is? Quote Link to comment Share on other sites More sharing options...
western Posted August 12, 2012 Share Posted August 12, 2012 there shouldn't be anything between the seal lips, any spacer or filler should be removed before fitting, BUT if there is a circular spring inside that must stay in place. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted August 12, 2012 Share Posted August 12, 2012 No, not in the seal itself, in the back of the recess for the seal, either the flywheel housing or the block, not sure which. I refitted the new seal flush with the face of the flywheel housing, as the old one was, and all seems well. Quote Link to comment Share on other sites More sharing options...
western Posted August 12, 2012 Share Posted August 12, 2012 flush with the housing face will be fine. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted August 12, 2012 Share Posted August 12, 2012 I thought the plastic bit was to keep the seal lip turned in the right direction to seal, removal renders the seal no good. Or is that just the 300 seal ? Mo Quote Link to comment Share on other sites More sharing options...
western Posted August 12, 2012 Share Posted August 12, 2012 don't know about the 300tdi seal, but the 200tdi workshop book, says it's only to keep the seal shape & must be removed before fitting the seal. Quote Link to comment Share on other sites More sharing options...
rudd86 Posted August 25, 2012 Share Posted August 25, 2012 the manual i have says send the seal all the way home into the flywheel housing as the machined face in the back will make sure the seal is fitted square. think you just use the plastic bit to get the seal to start over the end of the crank without damaging it. I did a seal the other day and fit it flush with the flywheel housing after reading up on the net, needless to say ill be taking the engine out again next week and doing as my manual says.

JimAttrill Posted August 27, 2012 Share Posted August 27, 2012 The 300tdi seal must not be oiled before fitting and neither must the crank be oiled. Apparently the seal is pre-treated with something (they don't say what). I presume the same applies to the 200tdi seal ..... Quote Link to comment Share on other sites More sharing options...
Maverik Posted August 28, 2012 Share Posted August 28, 2012 Buy 2... I knackered the first one putting it in... I now buy at least 2 of all seals i go to replace, they can be stubborn buggers and before you know it its bent or damaged... Quote Link to comment Share on other sites More sharing options...
