I have a 2002 MXZ 700 I’ve recently acquired. It was in non running condition. I’ve put it back together with new jugs pistons and a few other parts. It appears the top of the crank case mating surface is not flat. 1. Is this normal? It’s not wavy it just looks both cylinders are sloping...

I was doing some pre ride maintenance on my 08 Summit with the 800r PTEK and noticed my clutch had some movement up and down. Pulled it off and can move the crank up and down by hand. Obviously this seems bad. I'm assuming the bearings are shot. Sled will still start and run fine even did 20...

Purchased a tricked out Trygstad motor, new reeds, boots, and a clutch kit from I backshift. Performance was great, until the pto snapped at about 130 miles. E- mailed them on the same email chain I purchased the motor with, attached pictures where you can see the oxidization from the...

So I've been working to transplant a 04 600ho motor to a different chassis. The sled had been sitting for about 5 years without running as it was in a pretty bad accident. I finally decided to make use of the motor as it ran good, had a pretty new topend, and I found cheap chassis to put it in...

I just bought this sled so I don't know the history on it. It has a little over 4,000 miles. It has vibration in the handle bars/tunnel/running boards. It has kind of a groan noise to it too.. The vibration starts to become more noticeable at about 20mph. The track is really difficult to...

I am ready to put my 06 Summit 800 engine together and have found I have a problem. Earlier this year I bought a MCB reman crank with right around 1000 miles on it. Everything appeared to be in order and the bearings all felt tight. Today upon inspection I found that the PTO connecting rod had a...

Need help diagnosing a problem with my 1996 Ski-doo Grand Touring 670SE. The oil in the reservoir appears to be draining into the crank case when the sled sits over the summer. Looking for tips on diagnosing where the problem is. From what I understand it could be an inner crank seal problem...

I was looking to order a rebuilt crank from CV Tech and noticed a 2014 600RS crank doesn't have warranty as it is for a race sled. Is there another crank I could use off another model that would be the same and that way I could get warranty? I used the search function but most of the posts...

So last Fall, when I pulled my wife's 2006 MXZ 500SS out of storage, PTO cylinder was flooded with injector oil. So the dealer replaced both oil check valves (one on each cylinder). My wife only rode about 100 miles last season. So this Fall, when I pulled my wife's 2006 MXZ 500SS out of...

Hello All!! Time to start working on the sleds!! I have two 2005 500ss sleds that I've owned for a while now. Love them. Both ate their second sets of pistons at the end of last year (blew top ends on last trip of season). Each engine has around 14,000 miles on the crankshafts. Cranks are...

My friend went to a dealer who told him the 2018 had a change in the crank. Maybe he is confused with the 2017 850 crank change? Anyone aware of any major changes between the 2017 and 2018 engines? My friend is looking to buy an 850. Any good reasons to buy a 2018 over a 2017? Thanks!

Hello and thanks in advance for any comments! I just picked up an 01 800 mxz with a bunch of cool bells and whistles , (extended chaincase, 151 rev skid and track, Diamond S lightweight hood, tubular trailing arms, boss seat, etc, etc, ) Anyway I got it in a trade deal and it was "only running...

I've got a 2012 800 etec and grenaded a belt quite hard, after that i noticed alot of vibration at all rpms. looking into what could be wrong and measured the crank runout to be .007" on the PTO side crank stub. could blowing a belt hard and having it catch in the primary be enough to bend the...

anyone done a stroker crank on a 503 rotax using sections from 277 cranks? i understand that they have longer strokes than the 503s. also i read somewhere that someone made a big bore 81mmX61mm twin. could that be done with a stroked 503 to make a 721 big bore stroker? thanks in advance

Considering one of their reman cranks only, not a shortblock. I've found several complaints but those are always easier to find. Several people said a 100 miles and so far so good... but anyone with 10,000 miles on their cranks or engines? Negative or positive reviews welcome.

Dont know what happend with the "1000 SDI failure" thread, but wondering if anyone have any insight about this failure. Sled had been sitting for 2 years, just started and warmed up occasionally in my garage. Took it for a spin 2 years ago, wish i didnt... Pulled the engine - dissasembly...

Hello, I have an 2005 REV 500ss. I´m going to do an engine rebuild this summer. The motor has 12000 kilometers on it. Should I regrease the crank bearings or drill the cases for pre-mix to get to the bearings (what is the best thing to do?)? How is the reability if I should drill holes for...

Has anyone use a 670 PTO and MAG ends of the Crank to make a Custom 70mm Stroke Crank for a Single? If so, which Single Case did you use? Has anyone used either a 583(64mm), 617(68mm) PTO and MAG ends of the Cranks to make a Custom 64mm or 68mm Stroke Crank for a Single? Which Case did you...

Last season I put a CVTech crank in my 07 800 Ptek becase it was at 5000 miles and like most other ptek with 5000 miles the crank bearings and pistons went. Since putting this crank in I have done about 1500miles and now my crank has broke right in half along the counter weight. All the...

Hey out there, smarter people than me, I was hoping this wasn't the case, but after being a good little boy and doing some reading in the forums here I've come to the conclusion that my crank bearing is shot. When I had the engine out i didn't notice any grinding or wiggle in the shaft but I...
