Installing main bearings in a Vespa engine

[charley586]

Nice method... do you think it would work to pull out a bearing without damaging it?

[FEETLE]

AWESOME METHOD .... i actually use this to remove and install my ball joints and replace my front bearings on my 1994 Honda accord... simple high school science.... thanks for the VID

[notorious6452]

thanks buddy

Coglione leva i paraoli che pigliano foco.

[danzofear]

FN smart.

[etphonehome3]

Is a blow torch not dangerous when dealing with something that could potentially have oil on?

[anth69y]

i remember when you had to drop gudgeon pins in liquid nitrogen to shrink fit into pistons.

good video, don't know why people knock you or others that put videos up helping others 10/10

[canopypilot]

If it went in that easy why not just press it in and not chance ruing the seal

[mtnegm]

This is a great way i have read a couple of people giving you negative feedback however i have rebuilt a few engines but there always a little poo so this method is great, i appreciated the time you have taken to show us inexperienced engine rebuilders :) i will be trying in today!! thanks pal.

[k0ent]

... i cant watch this...

[MsTipsy10]

you certainly know your A}} from your elbow. Great video thanks for the tip.

[alfiojwz]

pff.... why do you make the bearings cold?

heat your carter , and they wil enter with out problems;)

make sure after closing the engine ,that the crankshaft is centered..

[TheBigTittyTwister]

Well done. Good job but this method isn't something special. I've done it many times this way. But your video is pretty helpful for people with less experience.

[superco0l88]

well done

[srgore67]

Great tip on freezing those damn bearings. I had mine in my freezer for hours and could never get it cold enough to get in my cr125 case.  I just happended to have two cans of air in my garage and this froze them in seconds. NICE JOB!

[iowancamera]

I'm the the old pros think I'm crazy, but that stuff gets things so much colder than the freezer.

[lyvid]

Nice job! "No need for an hammer".

I don't freeze the bearing because it goes to it's place pretty easily (try it ;) ) no oven either.

The original tool to place the bearing was an electrical resistance wheel-shaped, that heated up the case and then you'd put the bearing in there ;)

Btw, to the crankshaft, if you don't have the apropriate tool, you may try to pull it with the clutch (tightening the nut on the other side). That way you know it's centered just fine.

Keep going!

[lyvid]

After that, to close the engine, just fit the two cases togheter and keep closening them closer, moving the crank (because of the oilseal from the ventilator side) and kickstarting it (by hand :P) so it gears up, and fits nice and weel. Good luck ;)

job well done nice to not see a hammer

[iowancamera]

Thanks for learning us. If I'd have known your method, I might have tried it. Everyone else told me to put the bearings in the freezer and my cases in the oven.  I wasn't too keen on doing either. I definitely know an asshole from an elbow, and you certainly don't sound like an elbow.

[iowancamera]

Furthermore, you can't install these engine seals from the outside. It's an older 2 port engine from the 1960s.

[sexysoi6]

lie the casing on its side & cover the seal with a big socket so not to fry it.. but dont pick it up with ur fingers when u come to drop the bearing in!

[andreagiacalone]

you can hold the bearing in the freezer!!! Not waste the dust remover!!!

[americanzoomer]

Awesome job man!

[kiwi90ss]

Great work mate. Would be keen to see more from your engine rebuild.

[lllViperlll]

yah thats the method

[feboxxxx]

si tutto questo ok solo vi dico che certi meccanici li fanno entrare a martellate.....e poi ti chiedono anche 400 euro per aprire e chiudere il motore sempre a martellate...se potete fatevi le cose da soli.

[ErMatto1990]

secondo me questo è un' ottimo modo peccato che certe cose ce le debbano far vedere i tedeschi

[broadband01]

put in freezer overnight in a plastic bag is best :o)

[Nanometer45]

does the same thing except one takes 10 seconds compared to 6 hours

[mateuszsymbula]

cool. however do install the seals after the bearings... juzt in case they get burned.

[99Jazzman99]

Not possible on this Vespa engine, I'm afraid. The seals have to be mounted first.

[ktownwreck]

bro this is great! you should film every section of an engine build, the shops never show you how they actually approach this work..

[amicovespista]

tutto questo casino x mettere un cuscinetto...

[phren0]

son daccordo.

[firstresi]

I thought about solid CO2, to cool it down, but was afraid if the bearing gets distorted, because the ring and the balls are made from different materials(?) and wont "shrink" at the same rate. I could be wrong tho.

But the spray version is a great idea :-)
