86 Husky 400 case rot.

We are working on restoring a 86 400 WR. It has case rot in the crank case. Any tips on fixing this. I will have photos soon. Any tips would be appreciated.

If the damage is non structural, you can use JB Weld or straight epoxy. If you break the gloss on JB Weld, you must seal it with epoxy. Both work well in oil or fuel vapor environments. You need to dremel out the corrosion prior to application.

Done this , works well.

Here is what it looks like.

Looks like a lot of paving to do but try the JB Weld . if you have it TIG welded you will have a high bill and a severely distorted case

I would salvage the inserts for the swingarm pivot rod and use another set. I would prefer to have inserts epoxied in a bit sloppy holes than use that. Even ones that needed a bit of weld on cracks at the swing arm area and then epoxied in. What makes that happen some race gas and water mix and time. Would it really corrode any more with proper use and storage?

i have some cases laying around PM me

Anyone try solder to fix this?

Yuk, if it was me I wouldn't use that, take 2premo up on his offer.

Think those cases may be rooted but you could build up the important bits ( down where it is thin ) with devcon then there is paint made for the inside of high performance engines for the rest
Or just get new ones off 2premo.

I have not heard of Devon was is it and we're do you find it?

Devcon is an industrial epoxy. You can get it at MSC Industrial and Lowes has Devcon epoxy. You want something better than the consumer grade at a retailer. I recommend https://www.amazon.com/Devcon-31345-Ton-Clear-Epoxy/dp/B0006O8QQ0

I will check out Devcon thanks!

slick them over with epoxy . i have an 85 250cr and the cases looked just like that.

i used JB weld with no issues at all. i also repaired a number of clutch covers with the waterpump cavity rotted to hell.

Permatex also makes a good 2 part epoxy . comes in a little tray with a wooden spoon to mix it with.

The cases I received from 2premo were in awesome condition, I wouldn't waste too much time on those cases unless they were irreplaceable, but that's not the case, pardon the pun.

pun was good lol
