Re: Harbor Freight auger Help needed
The 1.0 is the thread pitch.
Metric bolts in that size can be in 1.0, 1.25 and 1.5 pitch.
The spacers in the DAX kit are 3/4" = .75"
The BMP spacers are 7/8" = .875"
On some engines by using the spacers alone, the .75 spacing allows the clutch bell to hit and drag on the flywheel, which is why DAX includes a bunch of washers to increase the spacing for the various engines.
By using the 7/8" spacers you will have no such problems.
The hardware supplied by DAX leaves much to be desired, I usually toss it all.
