farmall Posted April 28, 2014 Share Posted April 28, 2014 I think I need to have my real main seal replaced. Does anyone have any idea how many hours a mechanic is going to hit me to change this? It has the 400 auto transmission. Quote Link to comment Share on other sites More sharing options...

Sam (Bones) Posted April 28, 2014 Share Posted April 28, 2014 it ain't going to be cheap  here's an idea what's involved...   disconnect battery ground cable remove starter, torque converter dust shield drain oil and remove filter remove engine mount bolts lift engine remove oil pan, oil pump, rear main cap  now I personally like to loosen all main caps to get the crank to drop a smudge, makes it much easier the remove the old seal and install the new one clean the block and oil pan for new gasket re-torque the main caps and install the oil pump, oil pan and new gasket, lower engine, install mount bolts, trans dust cover, and starter new oil filter and fill the oil, connect battery cable  I'll bet a minimum of 6 hours labor Quote Link to comment Share on other sites More sharing options...
Ian Posted April 28, 2014 Share Posted April 28, 2014 I have done a small block in my sons truck in a afternoon. It is not that hard life you take your time. Use the felpro one piece pan gasket. Quote Link to comment Share on other sites More sharing options...
farmall Posted April 28, 2014 Author Share Posted April 28, 2014 Sam, I was always under the impression that you could access everything by pulling the transmission. Is the way you described more efficient in your opinion? Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted April 28, 2014 Share Posted April 28, 2014 If the engine has a one piece rear main seal it is possible to replace the seal by removing the trans in some cases. Your 402 has a two piece seal in the rear main bearing cap. Quote Link to comment Share on other sites More sharing options...
