Bore depth???

Post by **NafemanNathan** » Thu Aug 21, 2014 4:11 pm

Does anyone know the depth of the bores (From the deck) on an H22 block? (Perpendicular to the crank, so where the rods would hit the cylinder wall if they were going to hit

)

I found this, but I don't really know what any of it means so I don't know if it's helpful to you at all or not:

bore size for a h22a usdm is standard A-87.010mm to 87.020mm (3.4256in) service limit is 87.07mm or (3.428in.) taper is .25mm or .010 in. service limit. distance from piston to cylinder wall .007-.030mm or (0.0003-0.00012 in.) service limit is 0.04 or (0.002in.)

the stroke of the piston is 95mm how far the piston moves up and down the bore

It's 95mm on a H23. It's 90.7mm on an H22

I wasn't sure if there was something else on the H22 that measured 95mm, I just couldn't figure it out

I've been messaging a guy at Darton, so hopefully he can help.
