H3 160 cu in gas engine build

All,

Starting a build thread for my H3 160 cu in gasser. I think there may be some differences from the tractor D15 II. Check it out.

For staters, my engine had to pistons stuck, which can be found in an earlier thread, but this one is for the rebuild.

Here is the block stripped and ready to be sent out to get cleaned and cracked checked.

Second grind

Here is where I see a problem with my dozer. Looks like someone put a tractor cam in it as there is no lobe for the mechanical fuel pump. The previous owner blocked this off and used an electric pump. I dont want to use a electric pump. Where do I get a cam with the fuel pump lobe?

Oh, and a tool I made with my $500 auction lathe from last summer, for driving out the cam bearings...

Is the middle bearing supposed to be copper and the outer two babbit??

So far,

$350 for overhaul kit except Mark II,

$1075 for Mark II,

Holy crappers....

$700 for 11 cubic inches...

Nope

Orangeman,

Thanks for the reply.

At first, I too didnt understand why it would not have been gravity fed, and then thought, yes, dozer sometimes get themselves upended in ditched, etc and if you were there for a while, the carb could run dry.

Here is a dumb question. Will the 149 kit work in my block?? or is the block bored bigger for bigger liners??

Quite a big hit in hp, so probably wont go that route. Probably just bite the bulllet and get the overhaul kit. Just found one for $1038, so thats $35 less than the last one I found.

I am also going to check with the shop I am taking the block to. They are in farm country (Antigo, WI) and maybe they have different answers.

Going to have them look at the crank and see what they say about 040 on the rods.

If I had sleeves made, I would have to get pistons anyway as two got distroyed on the dissassembly.

Thanks,

cb1

Old School: Some more to share - in discussion with the Factory personnel, was told that the 160 gas engines did find some Military application. As such, the military wanted to insure positive pressure to the carb. I have not been able to confirm the Military application of the engine, but did find it in stationary power units and used also for irrigation applications.

I have a unused 149 kit in the garage and could mic the dimensions if that would help.

Would like other forum members comment on whether an 160 block can use the 149 liners and pistons - there is a substantial cost savings to be had between the 149 and 160 overhaul kits.

Hopefully, others will come in here to chime in.

Good Luck this will be a good post to follow...Orangeman

There was a discussion about these engine kits last fall when agco listed the 226 gas engine kit as being on indefinant backorder. The short version of that discussion was that you want to order a power max kit for you motor. Power max makes the oem style power crater pistions. If you use a kit with a flat top pistion you will end up with a major loss of compression. I think indefinant backorder might have been the name of that thread in the farm equipment forum. The power max kits are not cheap but they do carry the correct pistons so you will get the 8.25 i think it is compression ratio. Nothing worse then putting all the work into a rebuild and having it come out with less power.

So, different blocks 149 vs 160..

Here is a picture of damage from past owner using a bolt a little too long. Will need to fix this..

I have a few 160 bare blocks, some liners, cranks, rods, pistons. I have saved them from mostly farm tractor, and industrial I60-I600.
