Really help me ty
Glad it helped! 👍🏼
That helped a lot thank u
Glad it helped!
Hello, I own a 2007 Can Am 800 atv. When I start the engine, it runs normally, but after I drive it for a distance, the fan works and the engine warms up. If I finish the trip and try to start the engine again, it happens like a hard crank, knowing that I changed the oil and starter, but I did not check The engine from the inside, thank you .
How do you know your on the compression stroke. And have you ever had to replace the RTV for the whole valve cover?
On the compression stroke the rocker arms and adjuster screws don’t have pressure on them and should have a little play in them.
The covers have a gasket ring on them so no need to replace them unless they are damaged!
on the AC thumpers an easy job ;-) my friend hates his 800 canam 2 cylinder !! ;-)
Yeah, the canams are hard to get in there to work on!
Great tutorial. I'm still confused about something. My ac 2016 is called a 500. You've called yours a 550. Is there any difference between the two?
There are a few different models of Alterra for 2016. The main difference is the engine size. Your 500 has a 443cc size engine and the 550 has a 545cc engine.
What are the measurements of the left side and the right side at minute 06:25?
The valves on the front of the engine (above the exhaust) are the exhuast valves 0.13-0.17 mm (0.005-0.007 in.).
The valves on the back (throttle body side) are the intake valves 0.08-0.12 mm (0.003-0.005 in.). These measurements are for Arctic Cat 550/700 h1 models!
Ok, so i have a question: Do you have to do this every 600 miles, or can you do it every 1200 miles or ever year and does it usual cost $300 just to atv valve clearnce inspected and i were to do it myself what tools/ kit do you recommend getting
You can do it every 6 months to a year. It’s a good idea to check them once a year. You can do it yourself easy enough all you’ll need is feeler gauges and the valve adjustment tool.
Ok so I have a kawskai brute force 2023 i bought it towards the end of the year so i should be good till towards of next year to do a valve clearnce inspection
@@spikestock You should be good. Some people check them sooner on new machines and some do it yearly. It would also depend on how much to use it.
Ok I really appreciate you answering my questions thank you
I attempted this but my rocker arm moves up and down a lot even at TDC. Is that normal?
Once it’s at TDC the only movement it should have once properly adjusted is the specific tappet clearance.
Thank you for the reply@@ArcticFrost . I adjusted them and I got my ATV running, finally. I had to adjust both sides a ton. Thank you for the videos.
@@bradyard3875 You’re welcome, Glad you got it running!
I have been looking for valve clearances for a 2013 AC trv 700. (efi). What I have been finding is very conflicting information on what the Intake and Exhaust valves are in fact supposed to be. Your manual shows values that do not agree with the information I was given by an arctic cat tech at a dealer. Or, for that matter, other videos and information that I have been able to find on a frustrating internet search. I could not tell you if there were changes in these values based on model year or a specific machine in the 700 class. Long story short, It may be best to rely on what the tech manual for YOUR specific machine and engine gives as values. As the saying goes: Trust but Verify.
Same clearances on all the 500, 550 and 700 H1 engines from 2009 to current models, the Alterra 600 is a different engine platform. But do check your specific service manual.
500:
0.08-0.12 mm (0.003-0.005 in.) - Intake
0.15-0.20 mm (0.006-0.008 in.) - Exhaust
550 & 700:
0.08-0.12 mm (0.003-0.005 in.) - Intake
0.13-0.17 mm (0.005-0.007 in.) - Exhaust
What is this procedure for?
The valves should be adjusted if the engine is hard to start or won’t start or if it is stalling or idling poorly.
