Author Topic: Front Crank Seal (Read 12823 times)

jrock · « **on:** Feb 22, 2008, 04:02:24 PM »

I'm loosing a fair amount of oil out the front of the engine. I pretty sure it's the seal.
My question is the way I remove the old seal. You remove the pulley bolt, then the pulley (with a pulley puller), and then what? The FSM said to pull off the hole oil pump assembly and I don't want to mess with that if I don't have to. Please help.

You'll probably have to remove the timing cover to replace the seal. The only other way I can think of to do it without removing the TC would be if you had a large and deep enough socket to fit over the end of the crank shaft to push the new seal in. Then you'd also need to have enough room in front to be able to lightly tap it in.

i bet its the o ring on the oil pump... the oil pump is nothing to be scared of really... few bolts and its off, and you dont need to remove the timing cover to pull the oil pump off

pulling the oil pump is pretty easy. it's removing the pulley and all the junk in front that's a pain. sure you could use a seal puller and remove the old seal but i think it would be better just to remove the pump. it would be a much cleaner job that way. you can remove the oil pump with out removing the front cover. at least i know on my old engine you don't need to.

Once you remove the front pulley, you can use a screwdriver to pry out the old seal. IMPORTANT!!! When you purchase the new oil seal, take the old one with you. Discount stores sell a replacement that is thinner than the oem, and if you bottom the seal out, It will only seal on the very end of the pulley. (They may not offer the spacer recommended, but they should have it or be able to get it.) I would personally use OEM from a dealer.

As far as the oil pump recommendation, any time the seal is replaced, I would pull the 5 bolts holding the oil pump, remove it and check the housing for wear. Also, pull the plug on the top pass side of the housing (carefully, there is a spring under it), remove the spring and the piston, and clean the piston and the bore. check for any scarring. use some fresh oil to lubricate the bore, re-insert the piston, spring, and cap. Check the o-ring that seals the pump to the timing cover, and re-install everything. I starved my engine of oil because some dirt got lodged in the pressure relief valve and jammed it open. Better to check it all out while you're that close.

haha, i swear thats what i said

The FSM shows the oil pump coming off without the timeing cover. Atleast I hope.
I would much rather fix the oil pan. Thats just the seal stuff right? RTV?

Damb your all fast. Thanks

no rtv on the oil pump! what is the problem is it leaking from the oil pan or the front seal?

the pump comes off without taking the cover off, i have done it several times.... after i did my timinch chain, i pressed the new seal in fine with a 4x4 of wood and a hammer.... but somehow tore huge o ring and my truck leaked like crazy... ended up buying a genuine toyota o ring (its a little thicker than the parts store ones and still costs like $10) and it stopped the leak

93tonkatoy · « **Reply #9 on:** Feb 22, 2008, 04:33:40 PM »

That is the thin seal I was referring to exactly. Advance auto has a spacer which is supposed to be installed behind it. I didn't find that out till after I had problems.

With a 22r, the only oil seal that's not going to give you problems is from the dealer.

With my 22re, I just removed the pulley (didn't even need a gear puller) and popped the oil seal with a screw driver (didn't have to remove the oil pump)

jrock · « **Reply #11 on:** Feb 22, 2008, 04:40:45 PM »

I like Tonkatoy's remedy.
So I pull the pan, pulley, oil pump.

PS Can anyone verify if that seal I posted is the correct thickness.

93tonkatoy · « **Reply #12 on:** Feb 22, 2008, 04:41:26 PM »

and make sure you grease the sealing surface with multi purpose grease before you install the pulley!

jrock · « **Reply #13 on:** Feb 22, 2008, 04:42:36 PM »

Multi?

93tonkatoy · « **Reply #14 on:** Feb 22, 2008, 04:43:19 PM »

If the oil pan is leaking, then yes. If it is not, there is no reason to remove the oil pan. the oil pump is bolted to the front of the timing cover.

jrock · « **Reply #15 on:** Feb 22, 2008, 04:44:47 PM »

Ok cool. What did is multi purpose grease?

i have actually used petroleum jelly without issue... you can also use ky jelly

jimbo74 · « **Reply #17 on:** Feb 22, 2008, 04:46:41 PM »

regular old grease. you buy it in a caretidge or tub.... jsut make sure its not lithium grease, any bearing grease type will work

jrock · « **Reply #18 on:** Feb 22, 2008, 04:48:24 PM »

haha. Not bearing grease?

jimbo74 · « **Reply #19 on:** Feb 22, 2008, 04:48:39 PM »

links dont work with parts america.....

also do not get the seals from kragens (parts america) get it from toyota... the aftermarket is not the same. the o ring is thinner than the oem... and that is what leaked on mine, somehow it tore when i was installing it

Well anyone know of a toyota store in Stockton?

93tonkatoy · « **Reply #22 on:** Feb 22, 2008, 04:49:59 PM »

any type of bearing grease will work. It is just to keep the mating surfaces of the seal and pulley from rubbing together dry. After the pump starts building pressure, the seal will get some oil, but it will last longer if it is lubed first. Also, polish the pulley with some emery cloth where it seals, just to knock any ridges or anything that might want to damage the new seal. I have an old pump in the garage, would pics help?

jrock · « **Reply #23 on:** Feb 22, 2008, 04:51:40 PM »

Pics are always welcome. I would think emery cloth would be abrasive?
I thought you worked at night and slept during the day Jim?

i do, i woke up like an hour ago.....

emery cloth is slightly abrasive, it will help clean the crap off the mating surface, just make sure to wipe it down good after you do it otherwise youll have little abrasive dust particles and that will also eat stuff....

not a toyota store... DEALERSHIP!

i know htere has to be @ least 1 dealership in stockton....

Dealership, sorry.

jrock · « **Reply #26 on:** Feb 22, 2008, 05:03:36 PM »

What is the seal called?

Is it the timeing cover oil seal? The guy at toyota didn't know.

jimbo74 · « **Reply #27 on:** Feb 22, 2008, 05:24:26 PM »

no, it is the front main seal. front crankshaft seal. also want the o ring seal. it is the oil pump seal.

jrock · « **Reply #28 on:** Feb 22, 2008, 05:27:48 PM »

Thats what I thought. He couldn't find that in the computer.

I called back, they have it listed as a timeing cover seal.
$20 for the main and $12 for the pump. Bamn.
