...and see what the mechanic thinks. It works perfectly on the redblock engines.
The Rope Trick:
Although I own both counterhold tools for the B230 and B21/23, I no longer use either one. Instead, I prefer a piece of cotton clothesline (nylon or similar is OK too), for what is called "The Rope Trick". It's quicker and easier than the "tool", and the basic steps are simple:
1 - Pull plugs and rotate crank to #1 0° TDC Compression
2 - Verify #1 and #2 valves closed - look thru oil fill hole: #1 cam should be pointed inboard and up about 45°, with #2 pointed horizontally outboard.
3 - Rotate crank about 90° past TDC.
4 - Stuff about 3 feet of clothesline into # 1 plug hole, leaving 6" outside (feeding the rope in thru a short length of heater hose makes the job even quicker).
5 - Rotate the crank backwards until the packed rope stops further rotation.
6 - Use socket, breaker bar, and pipe extension to loosen pulley bolt.
7 - Tighten bolt the same way, but start with crank about 90° before #1 TDC Comp.
8 - When tight to spec, back the crank up a little a little and remove clothesline.
To my knowledge, this is the only "trick" holding tool alternative that allows tightening the bolt to book spec of 44 lb ft, then an additional 60° (B230), or 122 ft lbs. for B21/23.
I don't know what the diesel torque spec is.
