Top End Rebuild Again: PART 2 of 2, 2002 MXZ 700

[@just-passin-thru]

I'd love to have a sled like that one! Been going through some tough financial times but I have faith that I will get something soon! Snowmobiling is in my blood!

[@Paisteboy]

I hope things turn around for you soon. A decent sled can help you forget the hard times and there is still plenty of time for that to happen before the season starts. Thanks for watching man.

[@just-passin-thru]

Thanks for the hopeful and encouraging words my brother.

[@Paisteboy]

You're welcome. If you end up getting a sled, make a video of it and let me know. I'll check it out.

[@just-passin-thru]

OK:)

[@aaronl9670]

Ether Fever come to wisconsin and buy my 97 zr 440.... needs some minor surgery but it is an amazing sled

[@doobyboy21]

Thankx to your videos I got my sled back and running again ! It took me 2 hours for each video ! Just wanted to make sure I wasn't missing anything ! First time I ever rebuild anything !!! My 94 Vmax is now alive and well with 130 PSI in both cylinders !! Many thankyou's to you and your patient brother !! Thank You !!

[@Paisteboy]

Awesome man! I'm glad the videos helped. Put some videos up of the sled.

[@doobyboy21]

paisteboy I will ! I got olds vidz but not with the fresh rebuild done by myself !

[@doobyboy21]

paisteboy Just amazing how we sometimes miss judge our mechanical abilities just because where scared of braking something or putting something up wrong !

[@CrayCRussain]

I just got a 94 vmax 600 with 70 for compression. I just got my rebuild kit today.

[@scottbuckley6578]

That's some good work there boys. This repair looks easier than replacing the track

[@Paisteboy]

Yes. Thanks for watching.

[@jasondrick2648]

Just about to do this on mine 😎. Thanks for the videos I will be following them the whole way!

[@Paisteboy]

You may want to drain the anti freeze first if you haven't started yet. If we were to do it again I would.

[@SilverGhost-yu4id]

Looks good! Sounds great! Nice work guys Ride on!!! Keep the vids comin I enjoy watching them ! 😎

[@Paisteboy]

Thanks. Will do.👍

[@pimpinpenz]

Today was a good day to ride sleds here! Tons of snow and it was only -1*C

[@Paisteboy]

Nice. Unfortunately we had a bit of a warm up. Hopefully it doesn't last long and melt all of our snow.

[@JDogg1009]

And it lives.... Good job guys... Sucks were gonna lose this snow :(

[@Paisteboy]

Thanks. I know. I'm not happy. The snow is melting way too fast. Hopefully the weather turns back around quickly. I want to ride.

[@TOPROLLER101]

paisteboy we got 3 feet up here and its still coming down.

[@Paisteboy]

TOPROLLER101 Lucky. You live in place that you can a lot of use out of a snowmobile. Enjoy it. It's just the beginning of the season so I'm no going to get bummed just yet.

[@mikedorunda1586]

Doing the same thing on a 2001 MXZ 800. How do you add the coolant, I’m concerned about air pockets?

[@Paisteboy]

Yeah. You need to get the air out of the system. I believe we hoisted the front end up off the ground with a strap to the garage ceiling and ran it. You have to get all of the air out.

[@ItDanks]

I plan on rebuilding my millennium 700 this summer. I've heard other guys mention things about ring gaps for the pistons, could you shed a little Insight on how the rings are sopposed to sit? If I remember right the concave edge is on top and the all flat edge is the bottom right?

[@Paisteboy]

Sorry I never got back to you sooner. We really just put the new one on the same way the old ones we on so I really couldn't tell you as I am not a mechanic and done have a rebuild book on this motor. Sorry I'm not more help. Hope you rebuild went well this summer. The season will be here before you know it.

[@alexbittle2900]

Paisteboy u got lucky when u run it out of oil usually the oil pump will seize and not work because it won’t have lube on it

[@Paisteboy]

Yeah. My brother did get lucky. The sled ran great after that and I believe the new owner has had no problems with it that I know of. Thanks for watching.

[@TheDingmann]

good work on the engine, now all he needs to do is take a power washer to that engine bay haha

[@Paisteboy]

Agreed. Thanks for watching.

[@gwood701]

hey paisteboy did you put anything on your base gasket or just fit it dry? I just put my 700 back together and it's leaking coolant.

[@Paisteboy]

No. We didn't put anything on the gasket. Check to see if the head is warped or maybe things were over tightened?

[@alexfarrar5389]

"I'd never put a base gasket on dry without cleaning the case and the cylinder bases with some 3m red scotch brite and brake clean or solvent. Then apply a very thin layer of threebond or black permatex" Cast aluminium is porous and can be pitted. Depending on which gasket kit you purchased? If it was from Bombardier they are excellent Cometic is second best in my honest opinion Windarosa Vertex are garbage. If it's leaking at the base then id say drain the coolant pull the cylinders asap and start over. Over tightened or torqued could very well cause i the base gasket to be crushed resulting in the scenario you have at hand. Any coolant leak is a tell tale sighn it could be sucking air / vacuum. Wich will cause a lean condition wich is not good. Good luck hope you get it straightened out 👍🏁

[@Paisteboy]

👍

[@jeffnations6649]

Nice job! Thanks! Now how do I get my clutch wheel off?

[@Paisteboy]

For the primary clutch you can use the water method.

[@jeffnations6649]

@@Paisteboy thanks, I cut it off

[@yoeybagz4575]

I just bought a top end rebuild kit im rebuilding the same sled. It came with 3 of those green gaskets. It appears 1 is thicker then the rest and then of the other 2 it seems like one is a slightly different material. Which one goes where?

[@Paisteboy]

We only had one gasket for the head and installed that. I'm not sure why you got multiple gaskets. The gasket that we used felt like a strong cardboard paper.

[@king123123100]

Sounds good. Did the rattling stop. What was it ?

[@Paisteboy]

Yeah the rattling stopped. It was a lost socket that my brother dropped under the engine that we never found. It caused that rattle until it rattled out of that bad spot.

[@bombidude]

During the first rebuild did you guy like the cageless needle bearings?

[@Paisteboy]

No. Not a fan of the cageless needle bearings. Just another thing to fall apart.

[@Gravitycreatedlife]

I know this an old video but where did you buy rebuild kit?

[@Paisteboy]

My brother ordered it online. Not exactly sure from where, but if you do a google search for your model sled and motor size that you have you should be able to find many options. Good luck and thanks for watching.

[@cheesecakemoto9503]

Hello! Same thing happened to my sled kinda. I have an 01 MXZ600 trail and it has piston slap. I ordered a new top end (same as you guys). The inside of the cylinder is a little scored up but not too horrible. Do you think that’s gonna cause me any issues?

[@Paisteboy]

It could. I would have someone with more experience take a look at them to be sure.

[@cheesecakemoto9503]

Paisteboy okay, thank you. I think I’m gonna hone the cylinders out before I do anything then see where that gets me

[@CrayCRussain]

@@cheesecakemoto9503 did you get by with honing?

[@gsxr1000jt]

I have a 2001 mxz 800 adrenaline. It does not have a carb heat knob/hose. The guy I bought it from drained coolant half way out last year. So I added coolant to top it off. How do i get the air out? Thx

[@Paisteboy]

You have to lift the front of the sled in the and run it to burp it.

[@thezacharykoerickshow3173]

do you need to bleed the oil?

[@Paisteboy]

Zachary Koerick We never did.

[@thezacharykoerickshow3173]

Sweet I've never rebuilt a snowmobile only bikes just picked up a 04 f7 with 4200 will be rebuilding it just to be safe

[@Codyrosa]

+Zachary Koerick If you take off the online injection lines I'd highly recommend you do otherwise there could be an air bubble in there.. If its like my sled it takes a total of 5 seconds.. seriously. Theres a screw you loosen and when the oil comes out of it you tighten it and thats it!

[@thezacharykoerickshow3173]

Cody Rosa yeah I did it. Very easy to bleed it just replacing the hose from the oil tank to the injector was a pain! I needed 3 year old hands for that.

[@Codyrosa]

+Zachary Koerick haha i hear you there! luckily I have a 90s polaris indy so its probably a little more easy to get at but still.. if I didn't remove the carbs, or the airbox or even the fuel lines.. i'd have a heck of a time trying to replace that oil line.

[@davidcoe8697]

How did the sled hold up after the rebuild this time?

[@Paisteboy]

+Brett Johnson He's ridden it for two seasons since this rebuild and has had no issues.

[@fredgonzini7099]

What did you do to the heads.

[@Paisteboy]

We didn't do anything to the heads. Why do you ask?

[@fredgonzini7099]

@@Paisteboy I thought the heads would after either be combed for sleeves replaced. I really don't know much about engine building but I like your video

[@Paisteboy]

Thanks. No. We replaced the bad cylinder, both pistons, roller bearings, and rings. Lubed it and put it back together. Unless the head is damaged you don't need to do anything to it. Thanks for watching.
