And so the debate goes on….. I totally get where you are coming from on this one and ‘partially agree’. I have literally just done this job for someone and left the crank side seal in with my thoughts being that the seal will get lubed by the 2T mixture - rightly or wrongly. As always, time will tell but it’s what MB do and he has a wealth of experience on engine rebuilds. Bolti
Fair comment about the sealed bearings and too me makes perfect sense also thinking about it, I’ve never used sealed bearings but have seen others do so. Nice work
I’d never thought about it being a problem but have been leaving the seal in my driveside bearing for the last 8 years and haven’t noticed any premature failure of seals, either in mine or customers engines.
If Innocenti never fitted them then that is good enough for me. I never leave the seals in and never had a problem after years of building engine’s. Bolti
I kept the seal on gearbox side, but made small openings at 3 and 9 oclock so gearbox oil can get in, so at the bottom of the bearing there will be a kind of oil bath always. Only time will tell if it works😂.
@@kickbackgarage it’s not enough to make me stop watching, but it does spoil it slightly. Others may like it, perhaps I’m just a bit grumpy. Looking forward to the next vid though.
The 2RS seal doesn't have a spring so it won't work like the main seal does. All it really does is add some drag on the main bearing and like you pointed out, keep oil from hitting the hallite washer and by extension the main seal. Good video, that one has annoyed me for a long time.
A big dealer told me off about this video. He says that the 2rs seal will let oil through. Well, my question is why leave it in if it let's oil through anyway?
When I fitted my hub bearing I was told to leave the seal in place as oil passes through it but debris is kept out. Sceptical I carefully poured some oil on the seal and it did indeed migrate through.
Rob. Pretty sure theSteelweasle was adamant you HAD to remove the seal on the bearing to ensure it got lubricated. Keep the videos coming pal. Looking at building an engine for the first time in 40 years!!
The bearing seal will let a bit of oil through and if that is the case, why keep it in, in the first place? I also believe that I didn't catch the oil leak as quick as I normally would because it didn't bellow out the white smoke when it started to fail. 🙄
Interesting comment Rob, I’ve always used main bearing with seal and never had an issue although I’ve never used Viton on the main drive crank side either and had no failure too date. Bad news on crank as they not cheap these days 😐
@@jameswade4761 yes. And measure clearence to the drive plate and mag house. This one has twisted so bad that it has been rubbing on the mag ans it started out with 0.4mm clearance!

never leave the seals in mate , you are correct . and it decreases oil flow over bearing they are designed to keep grease in and dust out ......
I’d never thought about it being a problem but have been leaving the seal in my driveside bearing for the last 8 years and haven’t noticed any premature failure of seals, either in mine or customers engines.
That's the thing, does it really make any difference? I don't think so
I always leave the seals and never had problem. But also the theory you explain have sense to me.
If Innocenti never fitted them then that is good enough for me. I never leave the seals in and never had a problem after years of building engine’s. Bolti
I make a brew and pour an extra cup, wait a few minutes, drop the viton in a plastic bag in the extra cup. They go in real easy.
I kept the seal on gearbox side, but made small openings at 3 and 9 oclock so gearbox oil can get in, so at the bottom of the bearing there will be a kind of oil bath always. Only time will tell if it works😂.
I always thought sealed bearings were for maintenance free and keeping dust out. So using sealed bearings to me is asking for trouble
Love the videos Rob, not keen on the music though. It makes it hard to concentrate on what you’re saying.
Sorry about that.

I listen to all the feedback and appreciate it. Its the only was I can improve the videos.

I've never left seals in bud & touch wood ( knock knock ) never failed. Sorry your missing out on rideout. What make of crank was it ? Cheers Rob 👍🏼
You'll have to put your own milk and sugar in matey skip, just sent you a coffee. Keep up the good work and look forward to the next.
Thanks sir! Saving up for a new hard drive

I was gutted when I stripped it. The producer has offered to fix it but that will cost me 80 quid on a product that I'm not sure I can trust.
@@kickbackgarage had it been tigged Rob ?
@@exsoulagent email on its way bud.
id be keen to know what crank it was , im looking for one to go with my rt195 kit i just bought, what do you recommend?
No brainer. Use the bgm on an RT. That's what I did after this one twisted.
Look at RIMINI LAMBRETTA CENTER shop article number X260 bye 👏
I have seen those but I prefer steel plate more than aluminium.
Like it , who's crank??
I'll let the dealer answer first but its not German.
@@kickbackgarage do you test the cranks before you fit them Rob?
@@jameswade4761 yes. And measure clearence to the drive plate and mag house. This one has twisted so bad that it has been rubbing on the mag ans it started out with 0.4mm clearance!
@@jameswade4761 I measure them in V blocks and dial gauge on a lathe.
Get rid of that bloody background music it makes it hard to hear you and concentrate on what you are saying. Thanks for the vids
