I have really been enjoying this series......although I'm not watching it in order (I probably will when I watch this again) but I wanted to say GREAT JOB! You're a very good teacher. Subscribed! I wish the best of all things to you and yours good sir.......
Thanks!
Glad you liked it. Sometimes I think I’m rambling. lol.
Make sure to watch it from the playlist. There’s a surprise in the middle of it. 😀
Permatex gray powersports sealant is good for its final torque spec after 5 mins been absolutely loving the stuff for cases and patching cracked intake boots
Great tip!
Nice work, my tips are to pre fill the bearings with the oil u are running, and don’t use so much sealant on the cases only need a light coat
Good info.
@@StreetersGarage yeah pre fill saved the initial startup life and on seals use oil not grease bc grease can potentially hold dirt n dust the oil will wash away fully with fuel, on base gaskets use a slight layer of loctite 518, to stop fiber gasket from weeping
Did you replace the water pump seals on the crank? Also what oil did you use in the water pump. Ty
The seals were fine. No issues so I left then.
0W40 for the oil. It doesn’t take much.
working on my 96 ultra 680 want to reset all three carbs do i use the drill bit method like you need on the 500 what size two drills bits do i use Thanks
Try .187 and .210
@@StreetersGarage Thanks
No problem. Good luck.
What are the two gears for on the crank? Not the one for the water pump.
Oil pump drive.
@@StreetersGarage Thanks. I'm getting ready to assemble one of these engines soon. First time. I normally work on single cylinder two strokes
No problem. You’ll be fine, just take your time and pay attention to detail.
What type of grease did you use?
It was marine rated grease. The grease is only there for first startup until the premix gets into the engine.
The oiling of the lower end during assembly is just as important
what oil seals did you use?
Winderosa
How do u put oil in engine??
It’s a 2 stroke.
@@StreetersGarage I know it is a 2 stroke but when I pull ed heads off oil was on crank case and how does oil get on crank?
There’s oiling lines on the outside of case that feeds the bearings. There’s also oil injection in the intake portion of the case. One per carb.
This is the 1st snowmobile.Its a Polaris Indy 1993 440. I found right side piston and cylinder scrod.I do not know if oil for fuel not working. Can u tell me how to check with engine torn apart?
Is it a fan cooled or liquid?
Most burn downs are caused by an air leak. Either from bad carb boots, bad crank seals or bad exhaust gaskets. Dirty or misadjusted carbs as well.
The oil injection typically never fails and if it does it fails in the wide open position.
If I end up with an Ultra it's your fault.
Mission accomplished!
DirtyFace George I second this! 😂
