Thanks! I’ll take a look at that as well.

I removed the jackshaft out the PTO side of the machine, after removing the Chaincase. To remove the bearing, I did have to use a press to get it off, and then install the new one-also with the help of a press.

Will do, thanks!

Yeah, it stung a little when I discovered it on mine, but I’ve accepted it now and seems to be a non-issue. I just won’t jump too many approaches with it lol.

Sent mine to welder all fixed and beefed up engine performance build now over summer

Yes, you do need it for 10% blend, it sends more fuel to account for the Ethanol, which is leaner by nature. E-85 is not recommended at all for these machines.

@@Nelson_Service knew that it'd be leaner just figured the efi would account for it good to know I'll try to stick to my non ethanol then

Yeah, the modern engines can compensate for it with EFI, but the older models such as this required two different fuel maps to run properly. (Accomplished by this switch)👍🏻

@@Nelson_Service I gotcha one more question belt alignment bolt big washer long spacer two small washers than shims on the back you got a tool to set alignment? Do you know what the gap should be using the tool can't find it anywhere

Not too bad, I was able to push them in without a press. I used my bench vise mostly and applying subtle, constant pressure.

@@Nelson_Service how far in did you go with your back plate it's kinda tapered wasn't sure to set it in to the bottom of taper or flush with the back I've been having those bushings kick out and destroying clutches last two years

I want to say it was flush with the back. This sled is still in storage, but I’m hoping to get it back in the shop this month. When I do, I can verify and let you know for sure👍🏻

I use Arctic Cat’s 50:1 Injection oil. It’ll smoke pretty good at start-up, but this video was shot after a short trip and after it is warmed up, the visible smoke decreases. How do your spark plugs look? There’s always a chance that maybe your oil pump is set slightly rich, contributing to excess smoke.

Thank you, pretty much the same, it is usually when it is cold that it smokes the most, less once it warms up. Plugs looked good last time I looked, but good reminder to check them out again. thank you

Yes I did, about 10 years ago 👍🏻

thank you, look like it would be more comfortable, also with the seat.

No problem, and yes it’s VERY comfortable to ride. Also very easy to transition from sitting to standing when needed.

I believe it’s 16”x156”

Thank you! And agreed, this engine just keeps performing year after year.

Throttle safety switch was my problem on mine.Yes,Pete could help him out.He has the f7.

I did check the TSS and that turned out fine. My next step is to test my stator. I’ll reach out to the individual above as well-thank you!

It could very well. I’d be very cautious running your machine if it has a crack on either clutch. It’s best to replace it ASAP to avoid catastrophic damage to it, yourself, and other machine parts.

Where best place get new clutch from

⁠A few options: Used-I’d check eBay and Facebook Marketplace. New: I’d try Thomas Sno Sports and Country Cat. I’ve had excellent luck with all of the above.

You won't find any new but almost all articats the older than 03s used the same sheves you may lose the rubber orange but that was put in for dust later I just got one off a 440 with similar helix though you can swap yours I toasted two secondarys in two years I believe these bushings were the cause installing new in my new to me 440 clutch using red white spring 55-52 helix and new rollers well see

Will do, thank you!

That switch tells the ECU to send more or less fuel depending on what ethanol blend you are running. I did purchase a fuel pressure tester last year and it spec’d out good. Also removed and cleaned the injectors just like you described above. So, now I’m on to the electrical arena. I’m hoping to have it back in the wrenching bay this January and will post another video with updates.

Not 100% yet, but I believe I have narrowed it down to the stator. Fuel pressure was great throughout the entire rev cycle, on the test stand. So, the fuel system seems to be performing just fine. I think electrical is my only other option. I’m hoping to have the machine back in the work bay this January and will upload more videos of my findings 👍🏻

Any findings yet on the problem

Turns out there is not supposed to be a lock collar on this bearing. So yours is correct.

No problem-That seemed to be a common design with that era of Cats. I end up discarding that O-ring and use RTV silicone instead. I coat the outer bearing race with a thin layer of it, then insert it into the chain case housing and assemble everything else around it. Then, I let the silicone cure for about a day before I add any fluid to the case. This has stopped all my leaking problems over the years. Hope this helps.

Good call-I also checked this and it's right on.

change belt and adjust defection @@Nelson_Service

Sounds really good. I did end up testing the fuel pressure, and everything checked out OK there. So, on to electrical I think.

Hey I just got mine running put roughly 80 miles on her today with no issues. Ended up being my voltage regulator. I picked one up on Amazon for $80. Wish I tried it first would have saved a lot of time and money.

Good eye! It sure is-it's a parts donor for my '70 Panther 295 EXT.

Nothing too crazy happens at that stage, you could remove the voltage regulator assembly and probably get a pretty good glimpse of your bearing.

Yeah, I don't miss this setup on the newer machines...that's for sure!

Thanks- The powervalves are operating as should, and are oriented correctly and cleaned. Secondary spring and other wear components have all been replaced with the same symptoms present after as before.

Replaced the spark plug boots, carbon built up and was making the spark arch at high rpm’s. Sled runs much much better now!

Thank you, will do. I did test the fuel system, and that all is operating within spec. Onto electrical I go.

Did u have engine light blinking any codes? i had my f7 run great up to 6700 when the pow valves supposed to open it set the engine light and run like crap ended being the wire harness chaffing to the servo motor.from what you are describing sounds like same what I had also dump fuel,those spark plugs are very rich too

I did test these, and both ohmed within specs, including the plug caps and leads.

I'll check this out. The one that's on there has seen some miles for sure.

Power valves are 100% cleaned and adjusted properly. Compression is 130 PSI on both cylinders. Throttle bodies are opening all the way. I will check the silencer and reeds next. Thanks 👍🏻

Agreed! I was able to summon the help of a friend that had a press to help me out.

I bought them off a private seller on Facebook Marketplace. They were new, still in the box from 2009-ish.

Totally agreed 👍🏻

No problem-some parts are getting tough to find. Found this on eBay: www.ebay.com/itm/255942499394?epid=1279013142&hash=item3b975c9c42:g:W2oAAOSwwXxjzsWD&amdata=enc%3AAQAHAAAAoH%2BzUIbMKNlxWlcvazY9NdoSxaBUlgk3V%2FipZkncv1AMEmJCkjU92Ab4bLlYmEfyX6sD4a4VGQ1cKPXIh6axW0KRkoEI0UU6NMlj5DPf0wqoxmaAT0Qn8NoPEZ3dIp9KL7xA%2FQ5QBbPnCTdznopZstG3p8%2FUtLS7zmJbIB9zuDpOzSRDQN9cGXZrT6WzaQSuqOzUuoihrWTupxNqykeOK7s%3D%7Ctkp%3ABk9SR_CFnfW9YQ Not new, but might be better than your existing ones? Otherwise, try Facebook. There’s quite a few machines being parted out in Arctic Cat Firecat groups. Hope this helps!
