spiderpigcity Posted June 29, 2011 Share Posted June 29, 2011 (edited) any ideas on how to remove the woodruff key from the crank at the front. I have removed the crank pulley and need to replace the fms. I am having trouble removing the woodruff half moon key from the crank. It seems to be very tight. any suggestions?

spiderpigcity Posted June 29, 2011 Author Share Posted June 29, 2011 eventually done it with a centre punch and lots of patience ! Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 29, 2011 Share Posted June 29, 2011 (edited) The fact it's tight is very good news indeed, if it were loose, or worse, loose in a worn key way, it would show the damper had been run un-torqued. Tap one end of the key down and the other should rise up. Then pull it right out with small grips. I can't remember, but I thought the seal would pass over an installed Woodruff key? If it will I'd suggest you leave it in place, and in peace. Edited June 29, 2011 by Chris Wilson Typo. (see edit history) Quote Link to comment Share on other sites More sharing options...
SimonB Posted June 29, 2011 Share Posted June 29, 2011 It does yes, no idea why you would want to remove it. Quote Link to comment Share on other sites More sharing options...

I bought another front key from toyota so i replaced it anyway. The FMS was dry with no oil on the timing belt or anywhere around the seal (this is what confused me in the first place). However i thought at first that it was the oil pump gasket under the seal that was leaking but i noticed there is a drain hole in the casting under the seal and this is where the oil was coming from. The oil pump has blue gasket sealer all the way around and the aluminium casting looks quite new, so it looks like i have a new oil pump. I replaced the fms only inserting it flush with the oil pump facing. I hope this has done the trick. We will see tmrw. Quote Link to comment Share on other sites More sharing options...
spiderpigcity Posted June 29, 2011 Author Share Posted June 29, 2011 Hi there mate, Done mine a few weeks ago. You have to be carefully with removing the 2 keys as you don't want to damage the keyway. Dont hercules a flat screwdriver in there, what I did was: Take a small wood chisel and cut it at approx. 4cm from the tip, now you lay the piece flat on the crank with the chamfered side facing the key. The chamfered side must be facing upwards, now take your hammer and carefully tap the backside of the chisel piece. You will see that the chisel slowly will force out the key perfectly. When putting it all together don't forget to apply MP grease to the oil seal lip:P and that it must be 'flush' with the oil pump body. cheers I got it out by tapping gently with a punch and eventually it came up. The problem is there is not a lot of room and you have to be careful not to damage the air con rad. I did lubricate the outer seal first and then used my fingers only to start the seal off and then a socket to apply light pressure to drive it square and flush. I did take my time with it as you can easily push it too far in. thanks Quote Link to comment Share on other sites More sharing options...

dude Posted June 30, 2011 Share Posted June 30, 2011 Here is a picture of the Keyway and the oil dripping from the casting above.[ATTACH=CONFIG]135248[/ATTACH] That is not really possible, the only way oil can be dripping there is if the ally has gone porous !!!! the oil drain hole passes behind that thru the solid part of the pump, also the blue stuff sounds like Hylomar, the pump should have a good quality RTV used as a sealant and not blue hylomar.

spiderpigcity Posted June 30, 2011 Author Share Posted June 30, 2011 ok, it could be the gasket then as i originally thought, will take it for a run and check. So are there any pictures of what a leaking crank seal looks like showing the oil coming from the seal? does it leak from around the outer lip or the inside of the seal around the crank?

ronttuk Posted June 30, 2011 Share Posted June 30, 2011 When i put woodruff keys back in i put then in the freezer for as long as possible they contract due to the cold and usually slip back in nice n easy when back at an ambient temperature the fit as snug as a bug Quote Link to comment Share on other sites More sharing options...
