 Posted: Wed Oct 03, 2012 4:45 pm Post subject: CR125 Shaft Seal Question |
 |
|
Guys,
My '94 CR125 engine is leaking oil around the power valve actuator rod seal. I went to change it tonight but it appears the large cover over the clutch/water pump etc. (don't know what to call that cover) must come off. Is that correct? If not, how do I get the actuator rod out of there? If that IS correct, any tips for removing that cover? Just pull the bolts around the edge and pull it off. Any springs or anything going to shoot out?????? Just replace the seal around the edge and the PV shaft or are there other gaskets I will need?
Thanks for the help.
Todd |

You should try reading it 
You need to remove the clutch cover also, that's what he's asking....

You mean, I can only talk sh about peoples post. If you say to remove the clutch cover then you know something right. Why would you only say, You need to remove the cover. Well, tell him how to fix what he is asking. Or is that to much for ya. I only try to help, you try to play games. Save the Roundy Round stuff for your Ken Doll. Forums are for helping people who dont want to take there stuff to someone that works in a hole and charge them $200.00 for something they want to learn about. Helping him by saying, take it to a shop, will only get karters away from the sport vs helping them out and not having to spend $$$$ every time something goes wrong. I help people on EKN from all over the world that ask questions, And I say to them, look at the stores or shops here on EKN for your parts. I think its great people from Canada, Italy, Mexico, to name a few, view this site for help. What I have seen lately is more guys pm me because of how some people treat them on this site. They feel that if they ask the wrong question they will be made a fool of. That is a loose, loose for EKN and its viewers. So, working together to help karters would be beneficial for all and not pull away karters with open end replies or just more interested in bringing them down.
As it stands now Todd still needs some help. You have done nada to help. Its ok to say, I DONT KNOW. You act like you do so. |

No I just correct people when they're wrong, in this case it was you, but you have a hard time admitting it.
Why don't you read to us what it says in your manual?
I'll help you out.......
Chapter 8 HPP
page 8-9
Governor/Linkage Removal
Remove the following:
HPP valve cover (page 7-5)
Right crankcase cover (page 9-2)
So I guess he needs to look at page 9-2.
I really don't see why I'm obligated to fix every CR125 in hear, I try and give the best advice I can, I think in his case buying, a manual for reference is his best advice and reading yours is your best advice.
You can lead a horse........

Hey Gents.
Don't mean to get all touchy-feely, but treating each other with respect is a good thing for everyone. This isn't WWF; it's people enjoying an activity together and helping when possible. Good PR is great for the sport. |

Well...I do have a manual but they always say to remove everything, even when you don't really need to! I disassembled my spare engine and indeed it appears that the large cover will need to come off to replace that seal. That sucks because I wanted to run my first race this weekend and there is no way I can get a gasket between now and Sunday. Other than the oil leak, the kart is FINALLY ready to roll.
On another note, some of you guys who tried to help with the top end bogging I was having may be interested in this. When I disassembled the power valve linkage, I found that the pin holding the actuator rod up top was missing. The linkage and the power valves were also hard to move. After I disassembled and cleaned everything the valves slid very easily and I reattached the linkage. I am wondering if this could have had something to do with my issue since I never really figured it out. I put in new reeds and a new cage but I could not find ANYTHING wrong with the old ones. The power valves could have been jamming half way open etc. It's all freed up now, can't wait to run it. |

He wanted to race this weekend but he cant because he didnt know what gaskets to get. Well, if you wernt so busy playing games we would have a man going out to have some fun.

Todd, its called decarbonizing. This is very common for these valves to get gummed up like you see.
You could get some gasket materal from an auto parts store and make one to fit. Get a sheet two inches bigger than the cover, like an 8"x 8" sheet. Lay it flat and mark holes for bolts. Find a way to punch out the holes to the size you need. If you have a bench grinder grind down the end of a socket to a taper and make a sharp end. Then punch out holes. Lay it flat again and check alignment of holes. If all is good then scribe around outside of the cover and cut it. Now you can cut the inside at the same measurement as the old gasket. If you are a little big on the inside or outside it wont hurt. It will take some time, but it can be done. Just trying to get you out. Hope it all works for ya. |

First it reads the same for like 90 through 99 years, secondly, I already offered to dyno test the thing for a flat rate of $50, nobody in here has offered that kind of help!!!!
I do not comment on everything in here, I like to set people straight, not fix it for them. Just admit it, you gave him the incorrect advice that he even knew before you wrote it... No worries I set him straight... Like my dad always says: "Only thing worse than no advice, is bad advice".
Todd, that oil you are seeing by the HPP shaft, is it really, really black? If it is, it's just the excess two stroke spooge from the HPP valves, if it looks like motor oil, then you probably have a bad seal. If the seal is leaking, #1 it's contained in the valve cover area, #2 it's not under pressure, and #3 that shaft would have to be missing for any amount to leak out, unless you have the gearbox overfilled.... I wouldn't sweat it, keep an eye on it.....
Todd, you been wrenching on that thing, but you don't know much about it, I know you're probably on a budget, but there's things you can't skip. You have no idea how much time or condition of the piston/rings, you need to lose the power valves. It's frustrating to try and go through all this on your own, and you're learning from this I'm sure, but if you dropped this off at a shop that could straighten out this mess, you would been having fun, running laps instead of posting 100 thousand times in here....
That's advice that keeps people in karting instead of grasping at straws from the keyboard.....

This was a post I made Sept 24.
Check to see if exhaust valve is completely open. On my cr250 I had to adjust them to where they where just flush with the ports and not fully open. When fully open they would be recessed to far up in the cylinder leaving a small lip around valve. I had to use a bolt down thru top of cylinder to adjust it just right to be flush not recessed. On your 125 I would just plug them off. |

Chris,
I'm sure you are correct. However, I know I will need to learn all the stuff about the CR125 as I plan to race it. I'll also be building a '99 this winter and I have learned alot already so it's good experience. I wonder if I do have the gearbox too full. The kart is on my trailer and the trailer is sitting with the tongue on the ground so the kart is on an angle (nose down). In its current condition that little recessed area at the bottom of that chamber fills with oil after an hour or two of just sitting (not running). It really looks like the oil might be coming from the outer case seal and not the rubber seal. I don't know who/when it was rebuilt but that case seal is sort of squeezed out in that area and there is some RTV in there as well....The '99 lower end I have is not like that. You can't even see the gasket when it's assembled. The '94 is squeezed out all the way around the case (could be over torqued or maybe just an after-market gasket). Regardless....I am keeping it level and taking it to open practice this weekend anyway!!! I have ordered the seal and will take care of that next week. Thanks for all the help so far. Can't wait to build a proper engine for Stock Honda this winter.
