I acquired a ht-131 and the previous owner was having a problem with the lower clamping assembly loosening and eventually snapping the splined drive shaft at the groove for the snap ring, so the bottom 15-1/4 inches of the splined drive shaft is still in the lower drive.tub. I purchased the whole drive shaft assembly from stihl, part #4182-710-3203. My question is can I just replace the splined portion of the drive shaft without disassembling the entire handle? I was thinking I could fast forward to the part of the video where you install the springs and bearings. I would start by inserting the splined drive shaft into the upper drive shaft and removing snap ring so i can slide the bearings and springs up the drive shaft. I have watched your video like 5 times now and it looks like my idea should work unless im missing something? Thanks for taking the time to make this video. Craig
Well I got the drive shaft installed and it appears that it's working like it should, fully extended I can turn the sprocket and I can see the clutch drum turn inside the motor housing. Only one issue though, the hole in the aluminum tube that in your video says it should be pointed to the right side, mine is pointing to the left. Not sure how critical the direction of the hole is or even how to rectify it?😮
@@stihlhead3338 Excellent job fixing it yourself!! I don't think it matters which direction that hole points. I just mention it in the video, because I like to return equipment (and vehicles that I work on) back to how the factory built them, so that there's no "evidence" that they've been worked on.
Cool, it's hard working on equipment when it comes to you in pieces. I just can't wait to try it out on the long overdue branches that are almost touching the house.😅 Thanks again I couldn't have done it without your video!🎉
At 5:55 you'll see that the upper drive tube and driveshaft are not part of this repair, and I begin to assemble the lower driveshaft and tube after that point in the video. The upper section was fine, and didn't need repair.
@@austinado16 I’ve got one that was brought to me in pcs. The splined shaft had a bow in it and was chewed up when one of the extender springs broke into two pcs. The springs wore flats on the spline about a third of the way around. I straightened out the shaft and took a dremel and mini cutoff wheel and recut the spline so the bushings would slide. The clamps are bad and your rework is a good idea. Parts are expensive or non existent for this model. Thanks for the video.
@@ReedSevitts-rh7hy You're welcome. Parts are readily available, and generally the solution when they have this much damage, is put purchase the entire upper and lower drive tube/drive shaft assembly from Stihl. This is a better value than spending umpteen hours of shop labor, for a marginal result, or to have a machine that vibrates badly because driveshafts are no longer true. While the entire assembly is expensive, labor to install is under 30min, and the result is a machine that is 100% and ready to go back into service. The only reason why I didn't do that to the machine in the video, is because I'd determined that the upper assembly was perfect, that there was no other damage, and only minimal internal parts were needed.
Where can I buy the drive shaft? Mine has a small bend. It's not bad, it works but because of the slight bend it makes the springs hit against the inside of the tube
Thanks for the help , only had the drive shaft slip out when bar got pinched but this saved the day
I'm glad the video was helpful!

These are challenging to work on, so take your time and maybe take pictures with your phone as you disassemble. Your idea will probably work fine.

You didn’t show the install of the upper inner drive shaft(saw head)?

Your local dealer. There are also dealers selling on ebay.
@austinado16 I tried looking at ebay and couldn't find any. Maybe I'm not looking it up correctly. I'll try asking the local stihl dealer
