got this for really cheap otherwise it would have been scrapped, still runs great and had a new water pump put on it, eventually would like to put it in a late 40's or early 50s chevy 1 ton flatbed, curious if anyone has any info on bellhousings etc. to mate a sm 465 to it?

Sure, You can learn a lot about your proposed swap by looking at my pictures:
http://rides.webshots.com/album/483943098JelLUj

I have installed a 4-53T in a 48 Chevy 2 ton, still have work to do, but the hard part is done. I also have a 52 1 ton, and the swap would be identical as the front of the frame measures the same.

About a flywheel housing to fit an SM420 or SM465. The 3-53 in a Gamma Goat military "truck" used an SM420. The flywheel housing from one of those engines is the easiest way to put one of those transmissions on your 4-53. The flywheel housings from a 2-53, 3-53, and 4-53 are interchangeable.

Looks like you have an industrial engine, it probably has a variable speed governor. It will work in a vehicle, but a limiting speed governor would be a better choice. You can use one from the 2, 3, or 4 cylinder as long as it comes from the same side of the engine.

Note that the blower is on the right side(passenger side in north America) of the engine you have. The Gama Goat setup has the blower on the left side. There may be a starter clearance issue with putting a GG bell housing on this engine as the starter on the GG housing would be on the right side and thus the starter may not clear the blower. Usually, Detroit put the starter opposite the blower on the inline engines(as is the case with your engine here).

You have an SAE flywheel housing there, likely a #2. This enables many smaller medium duty transmissions to be mounted to that housing. The Spicer 3053(5-speed) variants would mount and are available due to mil surplus from 2.5 ton 6x6. Another would be the IH T3x 5-speeds; close, wide, and OD versions available.

You may find more info about Detroit swaps at the 'DetroitDiesel' group at yahoo groups.

you may also check soem old log skidders .. many had 3-53 or 4-53s with 4spd trans I thing the 4speeds were normally the 435 trans or the sm465s?
Good luck I mess with them too... I have 6v53 Im doing up..it was Doug Doring's (www.teamdiesel.com) older race truck from the 80's ran 10 sec in 1/4 mile ..any how.
Thanks

Ken,
On my 4-53T the starter and blower are both on the left side, same with all the late 70's 4-53T engines used in Chevy and GMC trucks.
here are a few pictures of mine:



I looked at a GG engine a few weeks ago, Just looked at the pictures I took of it, and went out and looked at my 4-53...

I am pretty sure he can using the Gama Goat flywheel housing (to fit GM 4 speed SM420, SM465, or a 5 speed T5 transmission). Although I think for some reason the Gama Goat uses a different starter, 24 volts I know, but not sure about the bolt pattern. If you can confirm that your old starter fits the GG housing I see know reason why you can't switch the two housings.

That's good to know Grigg, thanks for the info and pics. I have an SAE #2 flywheel housing for inline 53 series that I would like to put on a GG engine and I was concerned about a possible blower/starter interference issue. Looks like from your photo I needn't worry about that anymore.

Now I'm a bit confused on why I was thinking there was a problem there.

Thanks again,

Ken

Ken,
I guess there is a chance the GG housing has the starter mounted higher up and there could be a problem?
Although from the pictures of GG engines that I have I think it will be OK.
Let us know what you find.

If my memory serves me correctly, that is a reverse-rotation engine, rotation on a Detroit is determined by gear placement and if the blower is on the passenger side it'll make it reverse-rotation. They are, however, easy to switch around, hell the block can be switched front for back!

If he would post a model number of his 4-53 we could decode it to tell if it is right hand rotation, but my guess is that it is.
The Gama goat engine is regular rotation (right hand).

Blower can be on either side and engine can turn either way independent of blower placement. It's the placement of the idler gear that determines rotation, the blower is driven from the cam, (or balance shaft) gear, and no matter engine rotation those two shafts turn the same way.

i know its a been a while, but i recently moved up to PA, down here for the holidays, got the Model# 5043-7201, Unit# 4D-29373, im leaning more towards a reverse rotation, engine was facing backwards in the loader, but i could be wrong

...5043-7201...
My 53 series book has this to say about this model number:

5 = 53 series
04 = number of cylinders
3 = fan to flywheel - industrial application
7 = right hand rotation (counter clockwise as viewed from flywheel end), exhaust manifold opposite side of blower, blower on the right(as viewed from flywheel end)
2 = 4 valve head, non-"N" engine, non-turbo
01 = starter opposite side of blower


So it's a 'standard' rotation engine according to the model number.

Update

finally received everything from the GG flywheel housing to the transmission, the starter is on the opposite side though with a 3 bolt pattern, im hoping i can stick with the original housing thats on it, since they do have the same bolt pattern, flywheels are same diameter, hopefully both housings are the same depth, i am still in the process of moving stuff up here, ill post pics soon
