Product Overview
BACKORDER NOTE: We've been waiting for our restock order from our supplier, but it has been delayed. At this time we don't have enough bolts to fill any orders. We hope to get them very soon and we'll fill orders as soon as we can.
This is a set of long and short head bolts for for IH D166, D188, D236, D282, and D301 engines in IH Farmall Tractor models:

706
Included:
- Long Head Bolts (with washers): These bolts are 8" long rather than the original 7 3/4", so a special hard thick washer (included) must be used with these bolts along with the original washers.
- Short Head Bolts: 6" long
Kit Options:
The D282 and D236 engines had either 7 short /7 long head bolts or 5 short/9 long head bolts.
If you're not sure yet which you'll need, you can cover your bases and get 7 short/9 long (and then you'll either have 2 long bolts or 2 short bolts left over).

- Kit CYA: 7 short/9 long
