- In this episode of Cecil's Shade Tree Garage I am working on a vintage Rotax engine. I first start by soldering in a couple new condensers, install a set of breaker points, Then I describe and show you how I change out crankshaft seals on this 1970's Vintage Ski Doo Rotax engine.
Can't wait to see and hear it run. Never like getting my hands dirty so I always wear gloves. Guess that's why must of my stuff is down. Got to get down and dirty to get it done right. Good video Cecil.
Thanks, I am hoping I can get back to it tomorrow. Yeah it can be dirty work for sure. Thanks again. You have a great day..Cheers.
Great video Cecil. You certainly know how to get the job done and the correct techniques. I look forward to hearing it running !
Cheers, Jeff.
Thanks Jeff. Even I learn something new each day...I am hoping to be back at it tomorrow. Thanks again..Cheers.
Fun to look over your shoulder as you bring this vintage sled back from the dead. cheers
I am glad you are enjoying it Bob. Thank you...Cheers.
..good evening, snow mobile technician, glad to see you are not in a snowbank..lol have a great week..good vid...
Good evening Bob.
Don’t know if you’ve ever seen Jeff Bradshaw’s channel- Elderly Iron, but he has a special torque wrench like yours but when he thinks that he’s got the right torque spec, he goes “Click!” Every time! lol!
Hello Peewee. No I haven't seen him before...But I'll have to go check him out. Sounds like I'd like his videos. Thanks...Cheers.
a trick : you can watch series at Flixzone. Been using them for watching all kinds of movies lately.
@Alexander Branson yea, been watching on Flixzone for years myself :D
Things I have done a thousand times without a glitch, company shows up and not one bolt comes without a fight or try and hold a couple wires together while getting the nut that holds everything back on and it either hits the ground or rolls up your shirt sleeve and you can't find it.... don't know how you do it with somebody watching... good times kids.. with love as I am seventy three so everyone is a kid to me
Hell Morgan. Yeah I hear you. My eyes are not as they once were, and my fingers are a lot more clumsy as well. Cheers my friend.
I save this video in my favorites for future reference. Thank you for posting because my ignition is off because you said 16 thousandth of an inch which is 0.40 mm and mine is set to 5.5 thousandth of an inch which is .14 mm. No wonder mine doesn’t start
Hi Cecil. Great video. Keep um comin my freind. Take care :-))
Hello Dave. Thanks I am glad you enjoyed the video. I shall keep the camera rolling. Thanks again, You take care as well. Cheers.
I enjoyed the vid, nicely done.
I am glad you enjoyed it..Thank you very much. Cheers.
Thanks for sharing 👍
You are very welcome matthew. Thank you for watching and commenting...You have a great evening..Cheers.
If you want that thing to really rip hard, set the timing using either the direct or indirect method with a timing light or buzzer. FAR more accurate, produces way more power and more reactive to throttle responses.
Hi Cecil!!😀😀
Hello Al. Hope all is going well. Cheers.
Informative 👍👍
Thanks Jorg. You have a great day...Cheers.
I'm working on a 294 rotax right now, your videos have helped alot but I was wondering where you find your parts?
Did you use Oem points and condensers, or Kimpex. I haven't had very good luck with Kimpex.
Yeah I use Kimpex condensers, They work as good as Bosch for the most part. Cheers.
Hey Cecil, was running my sled the other day it’s a 90s 377. The engine shut down on the trails, after this it seemed to have more pepper. Was thinking it was the crank seals? Has good compression, by feel I don’t have a tester. Just assume it’s running lean and that’s why. What are your thoughts?
Update: it was a crank seal and then I blew the PTO cylinder. Just rebuilt the motor but lost the electrical. Might’ve bumped the CDI while rebuilding. Hoping to get it all together this week, before we lose the snow.
I used the wrong soldering iron, I’m wondering if that’s why I get really food spark to one plug and nothing to the other. Ive checked everything a dozen times ?
Yes it maybe you overheated the condenser. Now I have seen folks install a set of breaker points and have the point wire backwards and it grounds out..Or they forget to re install the nylon washer on the breaker points. Let me know if you figure it out. Cheers
How does one get the point wire backwards? It just goes to the condensers
@@elsydro8064 If you twist the point wire the end of the wire terminal that is crimped to the wire can contact the point body when it's tightened up.
how do I know if my engine has points? it's out of a formula sl500 and has ducati ignition.....it must be electronic ignition
Does anyone know where i can source parts for a 1980 rotax 503 out of a 1980 moto-ski ? specifically points and condenser
Here in Canada I order them from Royal Distributing or Kimpex.
i got a rotax 503 that has spark on both cylinders but its just runns on the left cylinder, i have change CDI and lightning coil can the stator be the problem?
its new pistons and it was the same before the change
Can these seals be installed without splitting the case ?
It is not advised. It's the case that pinches the seals to hold them in...I've never had luck any other way, they just seem to eventually pop out :-( Best of luck though.
Where do you get your parts from?
I have a friend up here who has a small shop filled with vintage parts...If you need anything this is his phone# 705 647 4415, His name is Pat Murphy...Just tell him I sent you and you should get a good deal. Cheers.
Don’t hit the clutch with the hammer
Hello Arthur, If you are familiar with working on these clutches you will know a few small hits with a hammer won't hurt them, and you will also know that you always resurface the two sides with sandpaper when they are running, this takes out the ridges from years of use... Sometimes a good hammering is needed to get rid of these ridges.
