I think my main seal is leaking, front of engine, if so how hard to replace? thanks everyone for the expertise, It's on a 1972, 2000 cc engine, manual shift.
You will have to remove the timing belt, crank pulley and crank gear, take the keyway out of the groove, remove the old seal, (I drill a small hole in the seal, screw in a sheet metal screw and pull it out w/ a claw hammer) and tap in the new seal. I use a piece of exhaust pipe slightly smaller than the seal. Or you can remove the cover if you want more working room.
Thanks for the info, do you recommend removing the radiator for more room to get the seal in? thanks again.
Yes, removing the radiator would be best. You will need to get a streight on shot to remove the crank pully. Also, you will need to remove the Aux shaft pully and then remove the aluminum cover plate that is behind the pully, this will allow access to the seal. You will also need to remove about 1/2 of the pan bolts on either side and loosen some of the back pan bolts. This is because you need to drop the pan about 1/4 inch or so to get the seal in and out. You will need an auxillary shaft gasket and lower pan seal gasket.
Thanks 71pintorace and Turbopinto 7, I appreciate all the help. Turbopinto7, when you say I will need an auxiliary shaft gasket and lower oil pan seal would that be in addition to the Main seal? Or is that the correct terminology for the Main seal gasket? I want to make sure I have all the gaskets before I proceed. Thanks again guys, you are all the best.
The Aux seal gasket is different from the crank seal. It is a paper gasket that seals the Aux shaft cover AND the Aluminum plate that is essentially the top portion of the front of the oil pan However, you get this gasket with the crank gasket as seen here: http://shop.oreillyauto.com/ProductDetail.aspx?MfrCode=FEL&MfrPartNumber=TCS45076&PartType=925&PTSet=A (http://shop.oreillyauto.com/ProductDetail.aspx?MfrCode=FEL&MfrPartNumber=TCS45076&PartType=925&PTSet=A)
Sounds like a couple different theories at work here. If you are losing oil around the crank snout you need the front main seal which is a 360* press in seal. Same seal is used on the aux shaft and camshaft. If this is the case follow 71pintos instructions and the retainer plate and oilpan are undisturbed. If you need the oilpan end seal which is a rubber strip in a half circle between the pan and frnt seal retainer then loosen and drop the pan. If you remove the seal retainer plate, be sure the seal centers good on the crank snout when you put it back. $0.02 more, JT

To remove the crank seal , you " must" loosen the oil pan. I just did this procedure to my 73.

??? Why did you loosen the pan? Did you take the front cover off?
The cover doesn't need to come off to replace just the seal.

My logic is this. If there is a leak out from the lower front of the engine there is no way of knowing if it the crank seal, pan seal or front cover gasket. If you are all ready taking the crank seal out I would want to replace anything and everything that could possibly be leaking. The bad thing here is, there is no way of actually seeing if the crank seal is leaking because the oil leaks off the lip of the front cover plate behind the crank pulley. All you know is there is a leak in the front/lower end of the engine.
I guess you could just replace the seal with out removing the front cover but you chance having to take it all off again if that was not the cause of the leak.
My sentence " you must remove the pan bolts" was ambiguous, should have read " " If you want to replace all the components that might be leaking, then you must etc etc etc...
Gotcha! Now we're on the same page! :lol: Good point and I agree, do it all at the same time and be done with it! 8)
Thanks everybody for the input. If anyone wanted to know why some of us are on this site this is why. Great info that I don't think we could get anywhere else for are great Pinto's, thanks again, you're all the best.
