JD 350 front idler repair

Post by xeagerx » Tue Feb 21, 2012 8:21 am

I have OEM idlers on my 350, they are worn. From reading some of the past messages, sounds like I can rebuild them. Are they cast steel? What kind of rod? Is it nessary to preheat? Do they make aftermarket? Any sources out there? From Wisconsin.
Lots of questions I know..New to 350's and trying to fix what someone else covered with paint.
Thanks :?:

Yes! I do have more time than money,but how much is it really worth?

Hello !

I have the same problem with my idler on my 350 , I've been told that the CASTED idler can't be recharged because they will break due to the fact they are casted , but I've read that the ones form other vendors are steel one and can be recharged .

hope this help.
Dig in boy !!

Here was the most recent discussion on this- especially look at the hyperlinks I provided near the top of the thread for specifics.

I'm glad you posted that Tigerhaze! Sometimes I wonder if people are paying attention to whats already been said.... several times!... and not long ago!!

And on this note... The way I see it, Weld the "Blanking things up" Use some 7018 rod and see what happens. If the Idlers are junk then what is there to loose other than a junk idler! Go for it!!! :lol:

Thanks for your patience. I did read other posts.
I wasn't sure if I should ask specfic questions about a past message with a reply. Or make new post.
Rebuilding undercarriage and idlers are borderline..looking for new but seem hard to find..


thanks again :?
Yes! I have more time than money,but after the enjoyment of the repair is over, what was my time worth!

back in the day (which was a Tues. i believe ) it was common to weld up all the rollers....... that was before all the after market parts now that the machines are older and not many parts out there it looks like old-school ways are coming back weld them up!!!!!

It's really not a problem to make a new post if you can't reply to an old one, but just wanted to let you know that we have discussed previously so there is some good information in the archives.

I know on some boards people get offended if an old post is "resurrected", but I have never seen that on this board and I think it actually makes it easier for others to find relevant information on a topic as we discuss it further :D
