I bought this for a cat c15 acert sdp engine. Worked just like it should. No complaints and it beats paying what Cat is asking for the same tool.

You have to be very careful when engaging the timing pin... it is very ez to bend if it pops in the TDC hole and you rotate the motor even lightly... its not ez to hear the pin drop into the /timing hole and if you continue to rotate the motor, the timing tool is toast. I had to use my fingers in a larger port underneath the timing port to feel when the hole is near and then slowly and gently rotate until pin locks in place.... I bent mine and kinda straightened it to work for TDC on cylinder 6. But it's pretty much shot using it once. I'll use a 5/16 bolt moving forward..... good idea, weak metal pin.... rotating tool worked great.. that gives its a 3 star... don't buy it for the timing pin....

If you know what these are and know how to use them, it wouldn't make any sense not having them for what they cost. Anyone who owns a old school ride with a Cat motor are mostly half mechanics and most of them still working needs to be worked on. This purchase was for a friend who did a complete inframe himself and having the right tools is half of getting it done.

Height adjustment step missing and tolerance of the bore is way to much.

The timing pin didn’t seem to want to engage the flywheel, but it’s a good idea, I was hoping it would work.The turning tool and the injector height tool worked as advertised.

10thou difference in height compared to the caterpillar tool of same part number. Also does not have the 2 heights cut in the rod like it’s suppose to. Save your money and buy the cat branded one.
