Great video Mick, explaining the hidden workings of a motor which most of us would fear to tackle, not anymore! Classic video.
Glad you liked it mate
The cost of a new crankshaft made replacement cost effective and it is peace of mind for the new owner. This should help you to get a good price when the time comes to sell. Looking forward to the next part of this repair.
Yeah mate hopefully if it runs ok.
Outstanding Video, just filled in the gaps for me perfect. Thanks for taking the time
That Shaft Was well bent Mick and was nice to see you repair it i can't wait to see it all up and running again 😀 😀👍👍
Well hopefully it will run without any problems ta for the comment mate
@@themowerman ur welcome bud and I am sure it will do
im a shedhead like yourself, i buy and recon mowers. but i learnt something today. nice video mate.
Glad you found it of interest john.
cant wait to see this qualcast run with the new crankshaft , good step by step on what you do to replace this part
Glad you liked it mate
The sump gasket sets the crankshaft end play.
Great video.
Yeah I understand..
A simple easy fix he says, and yeah right ? . Can't wait for the second followup video from the big tattooed monk. Someone's going to get a resurrected beauty for a good price. Awesome to watch, thank you Sir 👍 Tam.
Well when it's back together we will see if it's a runner. Ta for watching

Ta.. well it all helps.. its expensive to run a channel that's the problem
@@themowerman some people dont beg for anything,there usually happy with,hit the like button
Wow awesome video.👍👍
Great vid Mick. I would have broken that for spares. £38 and a few hours work? Bargain! Happy days.
Yeah david.. hopefully it will run..
Great fix mick it's not something i would do if i got a mower with a bent crank i would send it your way 👍👍👍👍
As long as it's free I will take it mate lol
Good job, Mick.
Great vid Mick, cheers
Welcome
Great video
Really enjoyed
Good glad you liked it
love the content just bent my shaft
Oh that's no good.. hope you can fix it
A piece of pipe and a dial indicator can be used to straighten that crank in situ lol there is a vid on Steve's Small Engine Saloon , was about 15 mins work and the job was done
Yeah I hear seen Steve's videos.. he's a stand up guy.. but remember that there is always other ways to repair a engine.. I'm just showing one of the other ways
Wow, that was well bent. As you said, they must have changed the blade too,.
Yeah mate it was like new.. hopefully it will run ok once I have it back together
Just an idea here but pressure wash the underside as part of the refurb, I pressure wash the whole engine and takes a minute but brings it up clean for working. Never had an issue.
Good video 👍
Thanks very much
Trying to do a catch up on your videos as I am well behind, that shaft was well bent on that Briggs and Stratton engine.
If you get a new honda GCVx engine in with this issue which is the brand new Honda GCVx engine they are now fitting to most new mowers the crankshaft is alot easier to remove the compared to the old GCV engine and you don't even need to remove the engine off the deck. Honda have designed the new engine like a two stroke engine so sections can be removed and replaced easily.
First! Have a good one mick!
You too
Easy to repair crankshaft in minutes.
3k very soon probably before the next Live ...ooohhhhh!😆
Hey from Canada Mick. Got introduced to you by watching Taryl videos. Really enjoy your work! Finally subscribed.
I know this video is 3yrs old but i have a question - do you use any kind of assembly lube when doing this? Ir do you hav another method of lubricating parts prior to the first start-up?
I use taryl lub mate ..
Wow, never seen a crank as bent as that one!!
Well now you have lol
@@themowerman I could show you one that’s worse, so badly bent I had to cut it with the grinder to get the bottom casing off 😜
Mick little advice: please do not take shortcuts for example how you clean gasket - what method, how - I don't know.
I understand mate the problem is I try to keep my videos to 30min.. if they are too long people dont like to watch all of it..
Micks Mowers Try to speed up the video in some places like Retohax is doing - this will reduce time with more useful tips in each video.
I like when he says cheap 🤑🤣😂 I know that is right..
Just alittle bent lol.....good job
Lol just a tad lol
Ive got a good connect on kohler engines for a little over twice what that crank cost you if you get in a bind.
Im digging the lift set up. Ive got a 6 1/4 with a badly bent shaft. Never done that in my life or sheared a pin till i hit 51 years of age. It instantly turned into a tiller. Some ass clown put cross ties in for a makeshift flower bed and secured them with re bar but didnt bother to drive the rods down flush with the wood. I turned to continue cutting in the opposite direction and clipped the 2" tall 3/4" diameter rebar and thats all she wrote. Why didnt the key shear or the hub break? From what i understand the hub breaking off is the new shear key safety device. Curious how much is a new shaft? 38.00 you just answered my ? Thanks
Great video. Hmm no pan gasket ? What gasket material did you use? Should be a great running engine for a long time. Great job. Thanks for sharing.
It's a oil and heat resistant one.. it works well..
That crankshaft just reminded me we need more bananas 😂👍🍺
Lol..
For testing you can prime for a good time though the carb . which takes no tools .
Yeah I know mate
As a newbie and probably being a skinny guy not so strong as you, I will take the head piston of as well to can push back the piston more easily
Tell me if o am wrong
Cheers
NAW, piston slides pretty easy in it's bore, you're hands just get slippery & that makes it harder.
Where those trousers from mick please.just what I need for my window cleaning as I’m orange T-shirt’s and hoodies .go a treat they would
Amozon mate
Micks Mowers thankyou il have a look now mate cheers
How about doing a series repairing the unrepairable?
I can only do what I get come in.
What did you torque those 2 little bolts down to for the rod bearing?
Off the top of my head it's 120nm I think,
Great video. Thiught it cost more for that part.
Nope not on this model.. that's why it was worth doing
@@themowerman WHY DOES PEOPLE KEEP SAYING THAT ? YOU DID IT THE RIGHT WAY & IT WAS A GREAT VID. AN ENGINE COSTS MORE THAN THAT CRANK. FOR SURE. PLUS YOU MADE MONEY OFF THE VID. GOOD JOB SIR, Henry from PA.
Micks run a ruler on the bend crank you see the gap in the old crank
Will do
Open heart surgery. Good job Doc.
Well thank you sir.. the patient is resting now.. and recovery show be quick..
How your good mate..
At 33:10, after application of gasket sealant and reinstallation of the pan head, are all the pan bolts fully torqued after only 10 minutes (and then left in place for 24 hours before filling the pan with oil)?
Just kiss them down and go back later to do up properly
Hey my oil slinger wont stay perfectly put. Will this cause a problem?
Yes.. it needs to be correct
No need to take the top plate off only making work for yourself, actually it leaves you somewhere to balance the engine on mate, where did you source the new crank from ??
Hi Mick have you ever set the governor on a challenge mower with SEMEC se475 engine if how thanks Mike from Stockport
Hi mate. Undo the 10mm nut. Set the throttle to flat out on the carb.. twist the governor rod clockwise.. hold it and do up the nut.. hope that helps
@@themowerman Hi Mick did what you said . It starts revs then dies does the carb have a rubber o ring on the back.if I move governor shaft halve way it screams it's head off thanks Mike I Don't want to be a pain cheers
You definition and my definition of simple are clearly not the same.
Hi Mick question for you I have a petrol strimmer i put it away leaning against the shed wall went in a couple of days later and its leaking petrol could not find the leak put it back and noticed its leaking through the exhaust all the petrol was in the engine emptied it runs ok have come across this before. love the vids
Had something similar on a Stihl MS180 chainsaw and turned out to be the tank breather blocked. Once tank had pressure kept feeding fuel into the carb-cylinder-exhaust-air box. Maybe as a start Check your tank breather is working. This may be through the cap or have a separate breather tube out of the tank depending on the strimmer you have.
Try to loosen the tank cap a touch see it that works
Micks Mowers Cheers Mick I will try it 👍
what torque setting did you use on the crank mick?
135 to 140 inch pounds mate
I bent my crank shaft and I’m wondering where to get a new one
Try a website called Briggsbits
Wow, what would cause that Mick?
Phil, with the blade turning in excess of 3,000rpm, contact with just about anything solid will cause this. A root, a stone or some other unseen obstacle. The blade hits, then glances off the obstruction often bending the shaft and blade in the process. Simple diagnosis is, the mower starts vibrating badly. Most crank shafts can be straitened and blades replaced, but sometimes, a crank replacement is needed. Cheers! Zip~
As zippo said
Interesting that the crankshafts are not that hard to get hold of.
Once I had the number of the engine it was easy mate
Where did you source the new crankshaft from ?
Briggs bits
at last no beating the shaft to death with hammer.
YES, HE DID IT THE RIGHT WAY..
How did you find that crankshaft I can't anywhere???????
I just looked it up.. or you can take the make model and code numbers off the engine and contact Briggs bits by phone and they will find it for you
hi there can you tell me what model number crankshaft is on a Briggs and Stratton 450e
I will have to look it up..
Ok mate thanks you
have you looked up the model number yet
The can gear is plastic I remember when they were cast iron or aluminum made
Yeah those days are gone I'm afraid.. shame but true they don't make them like that anymore
@@themowerman Get a custom grind, LOL.
The piston get push up in the engine to remove crank
Yeah mate
Hi please if you see this if need spares for my Suffolf punch 43s can you help me pleas ?
Some lawn mower dealers or spares providers can help as long as you quote the serial numbers, usually the F0 number is the one that works. Just be warned the old Qualcast mowers that were built by Bosch are starting to have shortages in parts now as Bosch don't supply the parts anymore. Allett mowers now sell the old Qualcast bosch design cylinder mowers but some parts have been changed in design so they might not be compatible with the old mowers. The new Qualcast mowers are not related to Qualcast at all as they are a Chinese mower with Qualcast stamped on them.
Why didn't you straighten it up with a pipe?
You definitely can.. but how do you inspect for small cracks in the crankshaft.. I could snap and I'm not risking it..
Socks with sandles....?
Hell yeah.. it's all the fashion these days lol
can you look up the model number of a crankshaft on a Briggs and Stratton 450 e for me please
Send me your engine numbers as they are all different
@@themowerman can you tell me where the engine number on the 450e please
@@stephenwarner7973 on the valve cover
@@themowerman can you send me a picture of where it is on the valve cover please and thanks again
@@stephenwarner7973 send me an email so I can send you one
Simple fix: proceeds to disassemble the whole mower
Its simple enough.. what's the matter... Too difficult for ya...
How do you find the torque specs?
Look it up on the internet via Briggs and Stratton specifications
thats more than i would have done id have taken another engine from the shelf and fitted that
Yeah I hear that but I wanted to show how to change a crank. That was the point. Thanks for the comment
@@themowerman fair point
What ever that poor thing it hit, it had to hurt lol.
An elephant lol
Hey Mick. I subscribe but do you sub me. Just wanted to say I enjoy your blogs/vids. I'm watching this while having a cup of tea 😂
It's not really cost affective. For another $50 you can buy a whole new engine.
Yeah mate I appreciate that this was a how to video
norge696, That's hard to believe, don't know the conversion of quid too dollars though.
@@NoWr2Run crankshafts run from $50-75. Maybe not in the UK.
Where did you find a crankshaft part number 595024 briggs and Stratton
Looks like the price has now gone up to £50.. it's still available on the internet
