In part 7 of our 2017 Yamaha Raptor engine build, we’re ready to install the cylinder head. We’ll start by getting the head gasket on, and then we’ll show you the torque settings and the tightening sequence to get the head installed to Yamaha’s specifications.
There are a couple of other parts we’ll install, including the thermostat and an oil delivery pipe. We’ll also set the valve lash on our Yamaha Raptor 700, showing you the valve lash settings on the intake and exhaust sides.
Go back a step and see us install the valves in part 6: • Yamaha Raptor 700R Eng...

woww , he make it look so easy, than it really is, i dont think i can make it, even with all the right tools

[@goldenboygq9]

These videos help so many people out thanks again!

[@MaliceInCyberland]

Well organized, well edited, well detailed, and very well explained to the point that, as an amateur mechanic, I have zero reservations to perform this myself should my Raptor ever need such work... I was just looking for the oil-bleed bolt torque... Thanks!

[@PartzillaParts]

Wow, thanks!

[@Jweiss7939]

You are a great help and these videos are greatly appreciated.

Thank you. Great job

[@joevega748]

If timing is off by a tooth will it affect timing.

[@andrewvantassel5181]

Yes

[@oscaresquivel4740]

Would this also apply to a yamaha 700 viking ?

[@Timmyskills]

Hey, good stuff man!

[@Firestorm637]

Thx...wonderful job!

[@alejandrogrisales7151]

Como siempre ingeniero muy profesional todo organizado la limpieza todo gracias por compartir este valioso video...como lo mencione antes que dicha que tubiera traduccion a español

[@greggan100]

You forgot to torque down cam sprocket

[@PartzillaParts]

They were torqued to 14 ft-lb as called out at the 5:55 mark. We just missed catching it on video!

[@greggan100]

@@PartzillaParts i was waiting for you to go back on to it after cam tension install lol Brilliant videos as usual and very satisfying. Keep it up👌👍👍👍

[@PartzillaParts]

@@greggan100 Glad you are enjoying them and great catch! We considered going back and re-shooting it but the engine had already shipped out to it's new owner.

[@travissprague7775]

At 5.40 when u say becarfull not to drop them well I did drop one how far do I have to go in to the bottom end to get it back out just the crank case I hope plz help

[@mitchelldaniel2350]

Did you get it? I’d pull the crank side case cover off.

[@travissprague7775]

@@mitchelldaniel2350 ya I had to pull the cover and magneto was not fun but did my timing chain while I was in there

[@mitchelldaniel2350]

@@travissprague7775 I did something to the same extent. Dropped a wrist pit for wrist for piston down in the motor. Got it out luckily. Thought I was about to be splitting the motor. Stuffed some clean rags down in the hole gave it another shot, and got it. That’s one of them mistakes that you’ll only make one time.

[@sg6722]

I have a 2006 Raptor 700, turns on fine but dies within seconds, any any idea what could be the issue?

[@PartzillaParts]

Fuel or spark. In this case, I'm guessing fuel.

[@sg6722]

Partzilla could the fuel pump be bad, even if it primes?

[@PartzillaParts]

@@sg6722 Yes, just because it primes doesn't mean it's actually pushing fuel.

[@darrellchristie2445]

Another video that doesn't tell you what size the tappet screw is, to know which tappet tool to buy! 3mm? 4mm?

[@ryanwofford1482]

Where did you get the torque wrench at and how much is it to buy ??

[@zacharyadams6277]

It's just a snap on. You can get it on the tool truck. Probably around $200

[@quahu1472]

Can i take what ive seen here and apply it to a 01 raptor 660r engine???

[@PartzillaParts]

Similar concept, but different motor.

[@arbabsultan2938]

Very nice.

[@MatveyRF]

Best

[@arbabsultan2938]

Yes r u Selind Tools.

[@LTVoyager]

I must have missed it, but why does a two year old machine need an engine rebuild?

[@PartzillaParts]

It didn't. We just wanted to build one from scratch and show you the assembly.

[@anthonyk6265]

@@PartzillaParts did you ever tighten those timing chain sprocket bolts on the head cylinder great job great video
