Bell Housing

[G Gibby]

Blake, Other Members,
A you may have read I am Working on trying to add a reduction trans to my HG.
I have a pretty good Idea of how I am going to try and do this but I continue to try and find a better way as I go along.
I was hoping you or someone else may know of a source of stadard bell housing used on the HG's and or other manufacturers of power units.
I have been looking at different kinds of industrail equipment which use bell
housings similar to the HG's just different sizes.
Additionally is there a reference for standard engineering equipment like gears and pulleys and bell housings and hydraulic pumps and cylinders, etc.
Hope someone can help.
Thanks,
Keep Well,
GG:)

Wow! I bet that would really move. Be lotsa fun in the snow!

George, sorry but I'm no help when it comes to your bell housing question. Hopefully someone will have some useful information for you.

Yes there are standard dimensions for SAE sized bell housings. The larger the number, the smaller the clutch and bell housing. Hydraulic pumps also have standard mounting flanges and shaft sizes, but a lot of them are made that are not standard.
Will do alillte looking, I am better versed on the pumps since I teach hydraulics.

Looking forward to it.
Having the name of some good reference materials would be a help for more than one project.

Everyone, I have just recieved a copy of the Oliver Bulletin CL-501.
This is having to do with the installation of the Trasco Underdrive Transmission.
It is very informative, I recieved this bulletin from the Flyod County Museum.
There is even a parts list to.
The instructions and diagrams of what is needed seem very straight forward.
Keep well,

George,
This is great news on the underdrive installation bulletin. I will be installing an underdrive in my HG soon. How can I get a copy of the bulletin? Did the Floyd Co museum send you the copy? If so, do you have a phone # or address? I appreciate your help with this.

Sincerely,
Jim Leap

Jim, Try "http://www.catt.org/fchs.html" for the Floyd County Museum.
They have a pretty good web site, and you can contact them through there.
They have always been helpful.
The museum is located in 500 Gilbert Street, Charles City, Iowa, 50619.
I am continuing the searh for stardard bell housing that may still be availible for the hercules power unit.
If I find anything that is availible I will let you all know too.
Keep Well,
GG:)

Did the trasco under drive use a model A trans?round bellhousings as used on the HG are SAE bellhousings,a standard accepted by engine mfgs.they work on a single digit principle...SAE # 4 bell housing for example...I dont know what size(sae#) the HG is

[John Schwiebert]

What is the center to center distance of the bolts in your bell housing when measured across?

[G Gibby]

From the Artical from the HPOCA March/Apirl 2001 issue.
The Bolt hole pattern is at every 45 degrees beginning a 22.5degrees from TDC.
6 6/16"from the center of the input shaft.
Will this help?

[ggibby]

I believe the SAE bell housing is a Size Five.
The SAE Standards are still in use today so any size five should fit onto the HG and OC-3 Flywheel housing.
This has mostly to do with the bolt pattern I think the input shaft and the rest may need adjusting.
Still looking further into this.
Just an update.
Keep Well all,

I'm not sure where I seen the picture, but it was a model a trans w/the input shaft coupled to the output shaft from the clutch and then coupled from the output shaft of the model a trans to the thans of the tractor I dont know how the trans was held still I think he jusr used a plate between the frame rails it just sat where the driveshaft was without any bellhousing hope this was some help.

[ggibby]

Ron, That may be possible, but with the flexing of the frame it might be difficult to keep everything aligned.
I did however find a Trasco bell housing for my reduction set up.
There are some repairs that will need to be done to give good service and peace of mind so that it will hold up under use hard or otherwise.
I hope that everyone will continue to add posts to this topic as they find similar modifications others or they themselves have made.

I am also looking for a bellhousing to put on my Hercules engine and when I find the one I need, I will have a good one to sell or trade. I am putting the engine in my truck but it came out of a John Deere combine. I do not know if any of you guys can use it or not but I think from the book I have on the engine, it is an SAE #3. I do not want to sell right now unless I find one I can use but it is on a 4 cyl. model OX Hercules and may fit other models.
