My bike is terminal (too expensive to repair)

[Grendel]

Went to get new chain and sprockets fitted today since been putting it off for months. But disaster apparently the front drive shaft is too badly worn to replace the front sprocket and needs replacing but been told it would cost more than the bikes worth to replace the front drive shaft.

Apparently the rear sprocket had also near enough undone itself due to the front sprocket jumping about on the drive shaft and that the suspension is set on the softest setting so very bouncy.

The 2 option he said I had was either keep running it until it dies since it would cost too much to repair of do a temp fix by welding a new front sprocket onto the shaft and stiffening up the Hagon rear shock.

ANYONE on here able to fix a problem like??

you got nothing to lose by welding it on really have you except a longer life for the old girl.
if you weld it on in three places you could even cut it off at a latter date when you need to change it again and weld on another.
Does that sound too easy, cos it is cost effective......

OH and mig weld it it's stronger than arch, and less penetration so easier to grind off latter

just cos your shaft is worn doesnt mean it wont last for years yet, its not an mot failiure or anything so unless it gets dangerous and starts spewing oil on your back wheel id run it into the ground then break it for ebay spares

As per other threads, if you go down the welding route make sure you keep some water handy to keep the heat off the oil seal around the bearing otherwise you will have an oil leak and have to split the case to replace!!

Bad luck mate.
If it was mine Id get it welded on , easy to remove with careful grinding and replace another sprocket.

if your front sproket last say 12k and you dont do that much milage then you should have a couple years out the old girl.

Spent too much money on it to justify doing that. It's not leaking oil just a bit crunchy/jumpy gear changes at present.

Got a friend with an Arc welder who may be able to do it. I presume it only needs spot welding on to stop it moving about and easier to cut off later to replace the sprocket??

Depend's on spec of arc welding rod's and MIG filler wire.
