I did not know they made a small journal 336 until I overhauled a W14 payloader. Rod. [Reply]  [No Email]

Case Co.people linked me up with Sandhill Equip. in Bassett NE and I was able to get skid units less sheet metal, drive systems and acessories. All small journal turboed 336s. Bolted them into 7/870 gas chasis and had 100 plus PTO hp tractor. We also ordered in all the top end parts off these engines and woke up a lot of older 7 and 870s Loren [Reply]  [No Email]

I am thinking of trying it. I know the top end and cam changes but do the 870 gasers have a balanced oil pump? Just an idea now but might try it. Also I have an extra set of 870 gas rods but they have a smaller wrist pin than my 970 diesel so i would guess they would not work on an 870 diesel. [Reply]  [No Email]

I sold a set I had from an 870 gas to a guy who needed them for a early 970 diesel. 870 gas uses a balancer oil pump just like the 267 and 336 Aren't the cams the same? What are you planning on using for heads? [Reply]  [No Email]

My VERY early 970 sn number 8650012 had larger wrist pins. I pulled the original rod bearings out dated OCT 69. Just need to find an intake for the 870 diesel. gas cams have a shorter duration from what I have read. Intake is open longer on diesels to max out air into combustion chamber. [Reply]  [No Email]

The 870 gas I knocked in the head for parts was in the 100's and I thought it was early. Count your head bolts. It sticks in my head that the gas had one less bolt. [Reply]  [No Email]
