shn7 Posted August 17, 2004 Share Posted August 17, 2004 I know that recommended practice when fitting a new K Series crankshaft oil seal says to use a bead of silicone sealant. Is a general purpose ok or is there a specific type that must be used 🤔 Steve. Link to comment Share on other sites More sharing options...
Jason Plato Posted August 17, 2004 Share Posted August 17, 2004 The sealant that Rover quotes is a rover part .  It looks and feels just like regular silicon sealant to me , its not likley to find its way intot he engine or oil so I reckon regular silicon will be OK . The manual states a 1mm bead then compresss overnight .  Dont forget you will also need to replace the patchlock bolts on the flywheel . Dave Link to comment Share on other sites More sharing options...
Rob Walker Posted August 17, 2004 Share Posted August 17, 2004 Also worth putting a couple of addiditional small screw fixings into the block to ensure the seal doesn`t move Link to comment Share on other sites More sharing options...
shn7 Posted August 17, 2004 Author Share Posted August 17, 2004 Thanks chaps. Caterham advise that the flywheel bolts can be re-used once given that it's a lightweight item. So will make sure they are loctite'd. Steve. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted August 17, 2004 Leadership Team Share Posted August 17, 2004 IIRC the Rover (Unipart) item is product code GEC 6000. It is a firmer setting compound than oridanry silicone sealant. Stu. Link to comment Share on other sites More sharing options...
Jason Plato Posted August 17, 2004 Share Posted August 17, 2004 For the sake of a few ££ , I use new flywheel bolts . My ankles are next to the flywheel Link to comment Share on other sites More sharing options...

shn7 Posted August 18, 2004 Author Share Posted August 18, 2004 Another question about this. What's the best method for actually removing the old one and inserting the new one. Is it a case of levering the old one out with something (thin bladed screwdriver) behind it? Is the new one simply pressed in by hand, tapped in with a rubber mallet or some other method? Hoping to get it fitted one evening this week. Steve.

Jason Plato Posted August 18, 2004 Share Posted August 18, 2004 Prise the old one out from the middle so as not to damage the engine block and hence seal .  do the 1mm of bead sealant then press in by hand and a little tap - you will see when it comes to get done .......... I then placed a weight on it and left it overnight .  dave    Link to comment Share on other sites More sharing options...
shn7 Posted August 18, 2004 Author Share Posted August 18, 2004 Thanks Dave, So you had the engine on it's nose then. Not sure I'll be able to arrange that but will consider some way to apply pressure overnight. Steve. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted August 19, 2004 Leadership Team Share Posted August 19, 2004 I have a length of angle iron with a couple of holes in to suit the flywheel/carnk holes - I use this to lock the crank from rotating when the engine is on an engine stand. when fitting a new crank seal, I've found that using this bar in combination with a couple of strips of wood enables the seal to be clamped in place. IIRC the Rover build manual requests that pressure is applied for only 1 minute - but best left overnighth  Stu. Link to comment Share on other sites More sharing options...
