Rich.2211 Posted July 1, 2013 Share Posted July 1, 2013 I think I may have had an over eager moment Whilst installing a new front main seal (front crank seal) I have inserted it maybe 0.5mm past flush. The Toyota Service Manual says for it to be installed flush. The worry about installing it too far is that it can block the oil relief hole? One saving grace is that I have the oil pan off at the moment so I can actually look down this hole from the other end (the bottom of the block) and take a picture.. I'm guessing the brown section to the left is the seal covering part of the hole. Does the seal cover a tiny bit of that oil relief hole even when fitted flush? or does it not cover it all? Long story short, do I need to pull this one out and install a new one, this time without my over eagerness? Cheers Quote Link to comment Share on other sites More sharing options...

bignum Posted July 1, 2013 Share Posted July 1, 2013 Did you fit a new pump?, reason for changing the seal? Quote Link to comment Share on other sites More sharing options...
ashbuster Posted July 1, 2013 Share Posted July 1, 2013 Hes had a full new gasket/seal kit and replaced everything while hes had his engine out mate Quote Link to comment Share on other sites More sharing options...
Rich.2211 Posted July 1, 2013 Author Share Posted July 1, 2013 Did you fit a new pump?, reason for changing the seal? I haven't changed the pump. Had a new front crank seal in the gasket kit so thought I'd change it whilst it everything was accessible. If I have to pull this one out and replace it with another then it's no huge issue, I just want to confirm that it is actually in too far before I pull it out and fork out for another front crank seal.

Got ya, i`d have been tempted to replace the pump while it was all stripped as you know what a pain it is once the motor is back in the car.

Chris Wilson Posted July 5, 2013 Share Posted July 5, 2013 I would have to disagree and say you should get away with that. Ideally a tad further out though. 2 potential issues. In too far the lip of the seal rides on the sides of the wear groove in the crank, and can weep. It can partially block the already marginal oil drain hole that allows oil leaking from end clearance in the pump back down to the sump, and build a pressure behind the seal. This can cause leaks, or in chronic cases, pop the seal almost out against the back of the cam belt cogwheel. Quote Link to comment Share on other sites More sharing options...

Hi Chris, it was actually myself who called you during the week and enquired about a crank seal. I took your advice and ordered another from Toyota and fitted the new one this evening. The one I fitted this evening sits flush as per the TSRM so should be spot on, touch wood. Thanks for your advice on the phone the other day Quote Link to comment Share on other sites More sharing options...

Swampy442 Posted July 5, 2013 Share Posted July 5, 2013 No worries, best to be certain! Expensive critters though. I got a crank seal from Toyota last week and it was 20 quid, seems to have come down in price a lot! Quote Link to comment Share on other sites More sharing options...

Swampy442 Posted July 10, 2013 Share Posted July 10, 2013 How did you get the other one out ?? ( the one you pushed to far ) Scriber and hook it out, screw driver and leaver it out. You cant re-use it if thats what you mean. Quote Link to comment Share on other sites More sharing options...

Rich.2211 Posted July 10, 2013 Author Share Posted July 10, 2013 How did you get the other one out ?? ( the one you pushed to far ) Exactly as Swampy has posted above, just be super careful not to scratch the crank. The seals are pretty tough little things but pull out pretty easy really.

mattdavies Posted July 10, 2013 Share Posted July 10, 2013 Ok, no plans to reuse one just replace when I do my cambelt Quote Link to comment Share on other sites More sharing options...
Rsoarer Posted July 10, 2013 Share Posted July 10, 2013 Cutting the oil seal lip and lever gently and carefully out with a taped flat screwdriver also works great (source TRSM) Quote Link to comment Share on other sites More sharing options...
