Part 3d BMW N54 Front Main Seal Replace
HTML-код
- Опубликовано: 9 июл 2024
- In today's episode, we work on the Front Main Seal (Crank Seal) Remove and Replace. Very common issue in N54's if you allow the oil filter seals to leak, causing the oil to drip on to the accessory belt causing premature wear. This in turn causes the belt to break and the physics of it all cause it to get driven INTO and BEHIND The front crank hub and literally get sucked through the main seal into the oil pan, where it clogs up the oil pickup, thereby starving your N54 of oil. This causes the engine to eventually have accelerated wear on items like the crank, cams, and any other moving parts, eventually BLOWING up your engine!

10 out of 10 video sir, hats off to you, simple ,to the point and with video
Thank you!
A few points that should be added.
You should lubricate the bearing with abit of oil this will help the seal slide over.
You should also prime the seal grooves before inserting the seal.
Use some RTV on the groves before pushing the seal in.
Yep he didn’t get any rtv in there at all. You are supposed to apply a thin (2mm) bead on the grooves of the seal, and then push the seal in.
Keep making videos it really helps out a lot more then you may think. I own a N54 and coming across your channel really just taught me a lot and gave me the confidence to keep working on my car no matter how bad of a hassle some jobs may be thank you please keep doing your thing
Thank you!!! I saw a large uptick in views. Was that you this week watching these vids?!
I watched your entire N54 series and some of your E46 and E30 it’s amazing. My clutch started slipping and I was looking all over for videos on how I can upgrade mine on my E92 N54 myself I love working on my own car it just brings me joy and I stumbled across your channel and you made everything so easy to follow and understand. I ordered a new clutch kit light weight fly wheel and I’m gonna switch out the rear main seal while I’m down there
It’s a little scary working under the car without a lift but I think I’m just gonna order one of those lifts that you put under your car on each side and they jack up the car pretty high and safely it’s some sort of hydraulic system. Would do it on jacks but I’m not sure how much clearance I would have to be able to drop the tranny
Very nice main seal DIY Frank. Regards Nico.
Thank you! Cheers!
The service manuals seem to suggest using loctite 128357 or 193140 not loctite 5970 sealant, they are considerably more expensive but come with a needle applicator. Is there a difference between these compounds and is there some documentation detailing that you can use the 5970 instead?
cool tool
N54s make good power but damn they do have alot of maintenance work. All in all I think it's worth the hassle.
Actually, I don’t know if it’s worth the hassle PJ. I think I’m going to finish releasing this series, but hold off on any more n54 work, integrations, repairs. N54’s are just too problematic
Worn Crank seal could be causing an oil leak correct? I replaced the OFH both gaskets 😂 still leaks a bit on the front I’m losing my mind now
oFH and oil cooler gasket 😂
How long does it take for the Sealant to dry and then cure. And the time until you can start the engine?
The sealant takes 5-10 min to dry before you can install the seal
@@Garageaholic so how about the loctite after installing the seal
When you took off the pulley didnt you turn the engine backwards by not holding the crankshaft bolt while taking off the torque bolts
Don’t need to with an impact
@@Garageaholic but you were using a ratchet to take off the 6 pulley bolts and the pulley was moving backwards. Or am I being stupid and the pulley has no link to the crank going back
THe pulley bolts are not concentric to the pulley. And they’re M8 size so small enough to easily break the torque by hand.
@@Garageaholic ah okay I've just seen other videos where they have held the crank bolt while taking off the pulley bolts to stop it from spinning backwards and when I was removing the pulley bolts, the pulley spun backwards a little.
a good mechanic cleans the entire area first so as not to work with so much dirt.
