Question for the welders. - Biker.ie : Irish Biker's Discussion Forum

ChipShop · #1 16th March 2009, 03:58 PM

Hey guys on my friends CR125 the chain seperated at the split link and damages the left side of the engine casing.

I have an ad up here advertising that I was looking for an engine casing but I am recieving very little response;

http://www.biker.ie/forum/showthread.php?t=72278

My question is would the casing be able to be welded? I have a few pics below let me know what you think also if any of you spot a casing for sale tell me and I'll buy it. Thanks.

Me thinks you have a chance of welding here. It's not a load bearing structure of the engine casing more like a cosmetic part shaped to keep the dirt out from the clutch cavity.

Got the part that fell off? Is it in one piece or did it shatter into many?

Give it a good clean and get the bike off to a weld shop lad. It is specialised welding here. Aluminum or alloy welding contact's I'm afraid I dont have any. Some of the lads might be of more help.

Sorry but my welding skills end at carbon steel and stainless. I would build it up with chemical metal and fiberglass, it should do until a casing comes on the market.

from the pics, in my opinion and experience, not a hope in hell weldin that, them casings are made out of pure s**te, could be wrong but im 95% sure im not,

I wouldn't attempt it but then I'm shite at welding. If you have the missing piece there is a slim chance it could be welded back in, but the back of the clutch actuator bushing has been knocked out as well and unless it can be made leak-tight you are wasting your time. Concentrate your effort on getting a new engine or casing for it - I don't believe it can be repaired successfully and you will waste money welding it.

if you are a good d.i.y. er clean the break up with a dremel get yourself a tin of devcon steel putty(made in Shannon)and build it up in stages until you get correct shape, this stuff can be filed etc. hope this helps

Is the clutch actuator working ok? The bearing looks to be supported but it will leak oil if it isn't sealed.

keith M · #10 16th March 2009, 09:26 PM

looks like some sort of cast aluminum dont think it would weld all sorts of shit in them casts

Saw that already, not sure if that will fit as it's for an 02 looks very similar though and it's $200 which we really didn't want to have to spend on it.

Thanks for the input lads.

I'm getting it looked at this week, hopefully it will be able to be welded as it's a much more expensive job if a new cover has to be bought anyway.

How much do you think this bike is worth with the engine damage, it's a 1998, seems to really just need this work and a clutch cable only thing is it's been sitting up while, I figure if I have to spend decent money on it I may aswell buy it off him, what do you think it's worth?

jono,b · #17 17th March 2009, 07:06 PM

hi, these engine covers are usually made from cast aluminium which requires a 4043 filler rod, i weld alot of aluminium cylinder heads which are made from cast al. also, only thing is i reckon this cover is cast from "puter", in other words pure shite, its the stuff that is left in the furnace after all the "good aluminium" is drawn off, there for this "puter" has a lesser bauxite precentage, which makes it horrible to weld.

p.s sorry to go all tech on the subject

ChipShop · #18 17th March 2009, 08:29 PM

So basically you reckon it's "horrible" to weld but possible?

It's funny I came across the CR on ebay and it has a pretty similar problem so I asked the guy the solution. He said "Silicone sealant or you could use chemical metal" to me tat makes no sense at all as I am not familiar with these products does this make any sense?

Here's a pic of his one;

Also I'd like the heel plate back on as I'd hate to get my pants pulled off me

~~ihaveagsxr~~ · #19 17th March 2009, 08:53 PM

id say very very hard to weld any you need a special welder for it

jono,b · #20 18th March 2009, 12:22 PM

it is "horrible" but it can be done my friend, if all else fails give me a p.m and we can sort something out

ChipShop · #21 21st March 2009, 02:31 PM

Forgot to get back to you fella's some mechanic in the Nutgrove area that my friend knew has taken it and he reckon's his lad will be able to weld it no problem I'll put pics up when I get it back as it's good to know anyway, thanks for the info lads.

ChipShop · #22 4th April 2009, 10:14 AM

UPDATE: Anyway just for future reference this can be welded and you would barely notice on the outside the only difference is that it can be a bit jumpy when you engage a gear from neutral when the engine is running but other then that the bike drives fantastic I have to say I am delighted.
