Re: [MBZ] I think the tensioner on the AZ bob car might have let loose again

Granted - a proper repair would require removing the timing cover. On Thu, Nov 14, 2019 at 7:48 PM Curley McLain via Mercedes < mercedes@okiebenz.com> wrote: > prob'ly, but its a relatively shallow blind hole About Dx1. Helicoul > needs at least Dx2 but Dx3+ is better. Or you could bore

Re: [MBZ] I think the tensioner on the AZ bob car might have let loose again

prob'ly, but its a relatively shallow blind hole  About Dx1.   Helicoul needs at least Dx2 but Dx3+ is better.   Or you could bore through, then try to make an oil proof seal with the bolt.  THat is do-able, but I'd want the timing cover off to do that. OK Don via Mercedes wrote on 11/14/19

Some aircraft aluminum parts come new with helicoils installed --- been using them since the 1960's. Never had one fail. On Thu, Nov 14, 2019 at 2:43 PM Andrew Strasfogel via Mercedes < mercedes@okiebenz.com> wrote: > This occurred 3 decades + 3 years ago > > On Thu, Nov 14, 2019 at 3:01 PM

Re: [MBZ] I think the tensioner on the AZ bob car might have let loose again

I'm not sure they are better - depends on your requirements I guess. I doubt that the solid barrel that screws into the aluminum case is better than the wire threads of a heliciol. I read on a motorcycle forum that they both use the same size tap for a given bolt, so the time-sert has to have

Helicoils have been an accepted fix for stripped spark plug threads for decades. Tried and true, they do the job well and are quite robust. -D > On Nov 14, 2019, at 2:52 PM, Andrew Strasfogel via Mercedes > wrote: > > When I tried to replace spark plugs on my W108 280SE the threads in the >

Re: [MBZ] I think the tensioner on the AZ bob car might have let loose again

When I tried to replace spark plugs on my W108 280SE the threads in the aluminum block got stripped so I needed a tech needed to insert a helicoil. I held my breath but it worked fine. On Thu, Nov 14, 2019 at 2:46 PM Rick Knoble via Mercedes < mercedes@okiebenz.com> wrote: > >I wonder if they

If the damage is limited enough, yes, that is a possibility I think. Didn't someone on this list try that repair? Max Dillon Charleston SC Nov 14, 2019 11:17:29 AM OK Don via Mercedes : > I wonder if they make a helicoil in that size? > > On Thu, Nov 14, 2019 at 8:53 AM Max Dillon via

What model car / engine? If an OM60X, I sure hope this doesn't mean the front timing case is damaged. That's a pretzel involved repair if it needs to be removed and replaced. Max Dillon Charleston SC Nov 13, 2019 7:57:51 PM Kaleb Striplin via Mercedes : > My dad has the car and he said he

[MBZ] I think the tensioner on the AZ bob car might have let loose again

My dad has the car and he said he was driving it to the VA yesterday and half way there it didn’t sound right. He went to VA and came back out and it wouldn’t start, battery dead. Said belt was real loose. I suspect the tensioner bolt came out again from when AZ bob fixed it. Sent from my
