Howco at Irvine continue to make good progress on fabricating the cylinder block to the point where it has now been sent for stress-relieving prior to machining. Howco has managed to keep the critical dimensions (distance between cylinder centrelines, positions of valve ports and overall width) remarkably close to the drawing dimensions and certainly well within the ¼” to 3/8” machining allowances on all the still-to-be-machined surfaces and we are pleased to report that no significant dimension changed occurred during the heat treatment.
Fundraising for this incredible component continues here.
