stihl bar stud repair
« on: March 12, 2012, 10:25:59 pm »
Looking for suggestions.  Only issue with this saw is the bar studs.  One was an attempted heli coil repair and the other is hogged out past that point.  Any tricks from the experienced Stihl guys???  Admittedly my experience is limited.

There is a bar stud repair kit offered by stihl that I remember reading about years back. Something about being over sized where they go into the case. I cant remember specifics sorry


other ideas   http://www.mcmaster.com/#threaded-inserts/=gn5tfy

more info  bar stud from an 056 MAG is 10mm and only it had the 10mm studs where they go into the case. 1115-664-2405  $7

stihl over size for 029 etc. So they must have for the mag crankcases too.

If the Standard Collar Screw is part #1127 664 2400, DG 8 thread, use Oversize Collar Screw part # 1127 664 2410, DG 9 thread, for 1127 series saws such as MS 290, MS 390
Installation:
If the thread has been stripped, the damaged mounting hole in the engine housing already has the required diameter (approx. 8 mm) and does not
need to be drilled out. Coat the DG 9 thread of the new collar screw with Red LOCKTITE 262, or equivalent and apply it squarely to the bar mounting face.
Use an 8 mm stud puller to install the collar screw into the engine housing and tighten down to a torque of 16 Nm.

If the Standard Collar Screw is 1123 664 2400, DG 8, use Oversize Collar Screw 1123 664 2405, DG 9, for 1123 series saws (021, 023, 025, MS 210, MS 250). It will also work on the 1130 (MS 170, MS180), and 1132 (MS 191T)
install same as above.

An oversize collar screw, part number 1115 664 2405, is available for alloy housings that have been stripped. The damaged hole will need to be drilled out to 8.5 mm (0.335 or letter drill Q) and rethreaded with a 10 mm by 1.5 pitch tap. Coat the threads with Red LOCKTITE 262, or equivalent, and install with the stud remover or use the double nut method. This collar screw is for the 3003 bar mount.

Thanks for that info!  I have several 029 and 056 mag II.  One should have a stud left.  Will keep this one updated

The 056 mag stud couldn't have worked better.  It cut new threads into the case without issue.  Red lock tight and it should be good for years to come.

Good stuff.
-Aaron

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.

Thanks for posting. That should come in handy one day. I knew of the oversized studs for the plastic cased saws. Never knew there was one for mag case saws.

Any Idea if there is something similar to use on the mag crankcase of an 015 its a ripper of a running powerhead way to good to part out but the stud thread is not great.
