Good puller - a must have tool for pencil type of injectors,
I feel it is a must have tool for this type of injector, it is well made, one "improvement" I made was use a jam nut to lock the puller to the slide hammer, as stated if the injectors have been in the engine for a time, a longer slide rod is needed, (my OTC, hub puller fit very nice, but the current length is such it doe not get in the way of some of the line and wires that cross above the engine in that location (4020 tractor), but on the one injector I did need the longer slide, would have given it 5 stars if they would have provide a longer slide rod with it, and came with a jam nut, to lock the puller head to the adapter. seems to be tough tool, It also works to tap the injectors down in the head, I am happy with the tool,

Good tool but needs longer slide hammer for stuck injectors.
Had to make a longer slide for hammer to remove old injectors from 1970 john deere 540 log skidder. They were stuck so bad that 2 of them sheared but placed the tool under injector for second round of pounding before they came out and tool is still like new. Glad I bought this. Saved me a lot in the long run for sure.

this was like a cheap toy
The puller wouldn't pull anything. My husband and mechanic had to make one. They got all 3 out by using a homemade puller.

Doesn't fit all CAT pencil style injectors
Once I received this I found it fits my 3208na 210hp engines but not the 3208T 250hp engine. The pencil injectors on the turbo engine are larger in diameter and the tool won't work.
