You are way better off using the proper tool.

I'd rather take a 2nd mortgage and let a Old Benz Mechanic do it.

It is nice to have the proper tool..
but with some blacksmithing/sheetmetal research concerning rivets and all the info in our archives you can also do it perfectly with the proper simple ball peen hammer and backup anvil type device. Go Slow , there is no rush. Be sure the pressure is being applied only to the pin when you start peening the edge of the pin... Getting it into position has been a problem for some people due to close tolerances...which on the other hand... once there... is a good thing...with the fact that a double roller chain has no side pressure to speak of... once you do mushroom that pin any the chances of it coming out are incredibly small...

More thoughts:
I think that before I would take a chance on Ball Peening the Timng Chain Rivets I would have to know that there was not much life left in the Engine to begin with. So, that I could justify taking the chance. But, if I bought a new Iwis Chain and a new Chain Rail Tensioner and the Enigne had good compression I think I would be looking to rent a tool to protect my investmet in time and money.

I have the correct tool, with both crimping teeth. It is available for rent I believe in that list.
Need a deposit of the full value of the tool at current prices (around $250) and you pay shipping both ways with full insurance in order to rent. Terms are not open to negotiation.

I did not measure it yet but was told by a benz mechanic who last year adjusted my valves that my tensioner looked like it was about at the end of it's travel not sure if he was just trying to drum up some buisness or not but the motor does probably have at least 225,000 on it but i do'nt know the history on it.I do know that the car will not go over 85 mph and I do think an 85 300 SD should do what the speedometer or close to it which goes up to 120.I'm thinking the chain and maybe some injection timing would put some new life in the old girl.

Checked the rental price seems I can rent the tool for $20+ shipping will probably go that route.

If it were me, I'd determine the IP and camshaft timing before I spent any money on a chain that won't affect the performance of the vehicle one iota. BTW, you've got 123hp rated at the engine..........much less at the drive wheels. It's a pipe dream to believe that a 3500 lb. vehicle with relatively poor aerodynamics is going to achieve 120 mph with this horsepower level. If it achieves 100 mph, you're doing well. |
