I have a minor leak at the weld between the exhaust flange and Y-pipe on my 99 ZL 500 (carbed). The location is quite accessable for welding (see pic).

Question is: Should I remove the Y-pipe from the machine before welding it?

My two main concerns with welding while on the machine are: 1) Possible electrical damage and 2) Y-pipe gasket damage or cylinder damage.

Thanks for the help.

Of course, with the lack of snow in Ontario, I have lots of time to wipe up the oil leak each time I run the sled in the garage!!!

Wire brush it very clean, then spot weld it until said hole is filled, allowing time to cool between welds. I'd be more concerned about it warping and not fitting again.

Yes, u should take it off when welding, U may get stuff inside of pipe and into the jug ,I would not take that chance.

 

[arctic cat kicks ass]

Take it off, it will be much easier, fill the hole and let cooling between welds

A friend just did mine while on the machine, not so close to the gaskets mind you, but I haven't had any problems.

 

[ready2race]

I would remove it,,especially if it's EFI,, no sence in taking a chance 4 bolts and a couple springs,, R2R

IMHO.....................no choice but to remove it.

You dont know who you are dealing with. This fella will bid on postage stamps on e bay if he can save a buck. :smilielol: :banana:

Thanks for the responses, guys. I will definitely remove the Y-pipe before I get it welded.

However, I’m so pig sick of working on that sled over the past 3-4 months that I’m still looking for a temporary repair solution which could plug this minor leak for a few hundred miles. (At that point, I’ll want to take off the pipe anyway to look at my new pistons)

I know you guys in the US like to use JB Weld to fix everything from broken dinner plates to cracked engine blocks!! I was kinda hoping someone had successfully used it on a 1300 F exhaust manifold…..????

BTW, Slddog, are you calling me cheap???? Hey, I’m willing to spend 5 bucks on JB. And.. I’ve got two cases of Guinness ready for when we stud the track (now don’t call me cheap because a case of Guinness only has four cans)!!!.

There's no way JB weld is gonna work there...been there, tried it. Burned right off in 5 minutes, and smelled something terrible. The temps at the Y-pipe are just too hot.

 

[teamgreenf7snopro]

like you said there's lots of time to get it done, so i would take it off.

Muffler Mender? I think that's what it is called. It's a paste for mending muffler leaks?

I removed mine to weld it up. It was a lot worse than yours but the y pipe was warped after the job was done. We had to notch the mounting holes to accpet the studs after.

The danger of welding on the sled is possible CDI / stator damage................welding off the engine means possible warping, damm'd if ya do / damm'd if ya don't.

 

[liftedandgifted]

Braze it with a coat hanger and torch cheap and effective. Plus it won't have to be removed.

 

[f7firecatkid]

remove it clean it up with a wire brush and if you have a MIG welder it will take no longer than 3 mins.

 

[FASTZILLA]

EASY...
remove it from engine...

wire wheel the affected area to bare metal both inside and out then clean with a good acitone cleaner

get a peice of 2x4 and place your Ypipe on it flange down clamp it into place ( vice grips / Cclanps etc ) and mark out the holes where it mounts to the head

then remove Y pipe and drill out the holes in 2x4 install bolts and clamp the Y pipe to the 2x4

then weld away going slow and letting it cool between small sections of welding

when the outside has been welded totally let it cool completely and remove from the 2x4 and weld the inside where its cracked slowly trying to not build up too much excessive heat

smooth out inside weld with die grinder ,file,sandpaper etc and reinstall and have fun ...

what I would do

what about FIRE arn't you worried about your sled catching fire....gas and spark dont really do that good together....
