Where do these rods go? 1936 Fordor
I’m working on my chassis and have found two rods attached in front of the rear motor mounts on both sides of the frame. They are factory installed with a flat round head bolt flush with the frame and a square opening for tightening. The head of the left rod is shown on pg 82 of the 35/36 Ford book put out by the Early Ford Club. My bolts are cut off about 4” from the frame. What were these bolts used for?
Sorry for no picture I’m not at home to use my computer.

Re: Where do these rods go? 1936 Fordor
Sounds like engine steady rods. they go through round bosses on the rear of the block and are held by castellated nuts . As yours have been cut ,you may need to put a listing in the wanted section on here.

Re: Where do these rods go? 1936 Fordor
Hi Everyone. Stretch Cab, I believe you are describing the 'stay rods,' 'anti-chatter rods,' or 'steady rods' that were designed (I think) to supplement the rear engine mount to increase longitudinal stability. The rear end is attached to the frame as you describe, the front end goes through the engine block.

I changed my search to the motor area of the 35/36 Ford book and they were listed there.

Re: Where do these rods go? 1936 Fordor
When the rear wheels start moving the car the force is movind forward by way of the rear axle, torque tube, transmission and engine. The transverse rear spring will flex a bit fore and aft, allowing the force to be resisted only by the front motor mounts and crossmember. The rods you are asking about transfer the force to the frame behind the transmission area.
In later models with the open drive shaft the spline shaft is allowed to move fore and aft so there is no force transferred to the transmission and engine. |

Re: Where do these rods go? 1936 Fordor
This pic shows how the rods attach on either end. Their function is to restrict fore/aft movement of engine/trans as torque tube exerts extreme forces on the assembly when releasing clutch, as well as while sustaining normal cruise. DD

Re: Where do these rods go? 1936 Fordor
Most likely you will need the longer rod (48- 6044) as shown below.

Re: Where do these rods go? 1936 Fordor
Ford used radius rods on anything that might move around too much other wise. The rear engine mount rubber can deteriorate to the point that the drive train will push the motor forward more than it should and this was the fix in the prewar model B & V8 era. Ford engineers felt that the later post war rear engine mount design was good enough that it was no longer needed in the 59 era but they really should have kept them.

Re: Where do these rods go? 1936 Fordor
The purpose of the rods was to prevent the clutch from losing friction with the pressure plate when reversing. The rear wheels connected to the transmission my the drive shaft tube in reverse would kink the clutch causing slip. My 39 with an 8BA would not go in reverse on a slight incline because they were missing. Had to install so could go in reverse anywhere. You need them!

Re: Where do these rods go? 1936 Fordor
You can also make your own by welding a bolt perpendicular to the end of a threaded rod. Does not have to be threaded entire length. Will not get you a Senior badge at Hershey, but will definitely work and do it’s intended job. That’s what’s on my 39 with an 8BA, same for any 8 in the 30’s.

Re: Where do these rods go? 1936 Fordor
It's not just reversing that can suffer problems. The clutch linkage can get stressed either way. I've seen kits that have a support that attaches at the transmission bell flange but they only use a single rod to hold things solid. Here is a link to an old thread.
