Help, 029 Super front bar stud striped out

[smoking440]

A freind of mine has a 029 Super that has the front bar stud striped right out of the plastic housing. His son is just a little guy and was trying to help Dad change bars and got a little carried away with the bar wrench
I thought I could just helicoil it but I see the thread is not a standard thead, but is simular to a lag bolt thread.:bang:
Any one have a botom tank they wana sell me? Sugestions?

As soon as I get this one fixed for them I wana build him a real saw like a 440 or 460 they cut a lot of firewood and need a much better saw. Realy nice family but it looks like funds are limited.

Depending on how bad the damage is you may be able to fit the oversized bar stud. Part number; 1127 664 2410 which has DG9 threads as opposed to the DG8 of the original. Don't drill out the mounting bore, coat thread of the DG9 collar stud with loctite 648 and install bar stud squarely.


EDIT; forgot to say you use two bar nuts tightened together on the stud to tighten it down if you don't have the designated tool.

I didn't know an oversized bar stud was available. The threads are stripped very bad, like just a smooth hole. :msp_scared: You can almost push the stud all the way in with just your fingers:msp_unsure:

Where can I go to get Stihl parts online?
Thanks,

So if I want OEM parts going through a dealer is the only way? Is there a link where I can see an exploded view of the saw and get part numbers?
I have used Baileys for more comon parts such as piston, jug, exct.

The bar stud JD suggested is just for the problem you have. YOu do not drill anything. You just make sure the old hole is good and stripped, and wind the new stud in.

Thanks for all the help on the 029. :msp_biggrin:

I replaced the stripped out bar stud with an oversized bar stud. I use used lots of loctite and just cranked it in with a stack of washers and a nut on top. It feels like it should hold real well as it went in real tight.

The owner is gona be real happy. Stihl dealer told him his only option was buy another chainsaw or pay them to replace the plastic saw housing. 5.50 for a stud, I wonder if the dealer knew about the oversize stud.

Thanks again you guys are awsome!!

Hey mate, where about did you end up sourcing the oversized bar stud from?

There are some on eBay in the U.S. Not sure about shipping to Australia . I would give you one if you were a little closer.

I know, old thread…

the problem…
Stihl 440 with a stripped stud that someone had “repaired” with a 3/8 sae stud . That stripped out. So, tapping the now oversized, oversized hole (.350) to 10mm .125 for the 056 or other OS stud ain’t gonna work.

suggestions?

maybe braze the hole and redrill and tap. I'll never tired brazing magnesium but it can be done.

I wouldn’t know how to start,
I would imagine to do that would require complete disassembly. At that point I might as well replace the case half.

Torch, Rod, Flux i'm sure you'd figure it out. You have to remove anything that could melt. I don't know if the seals would get to hot before you could get it done or not.

There is a product out there for making heat dams that works really good called Hot Dam. You could possible surround the area with that and heat the center to contain the heat or atleast help to keep it from spreading.

No idea if it would work tho.

This thread is 12 yrs old, and the OP fixed his saw with the oversized stud.

Correct, the entire saw would have to be disassembled. Not interested in doing that. It would then be more intelligent to just replace the entire case half and the owner won't go for that, lol. I'm looking for some sort of larger insert to just get a new stud in the saw, not completely rebuild it. But, thanks

Anyone else?
