Re: Engine replacement problems
Tom - I understand that the frame can sag a bit making it hard to fit any motor in the rear mounts. The problem is worse when you add new rubber mounts that are a bit thick. One solution is to get a frame spreader from any of the parts suppliers. Another is to forget the new rubber. My 31 A did not any thing between the motor and mounts, but it was obvious that someone replaced the motor in it's early life.

Re: Engine replacement problems
It has been my experience in the past that the replacement rear engine mount rubber pads have been too thick. I believe that both Bratton's and Snyder's have the correct thickness pads. I suggest that you simply buy their kit.

I found that Brattons pads were slightly to thick PLUS they were very hard to not allow any type of give at all when putting the original bolts and nuts on to assemble the parts thus I barely could get the cotter keys in the holes for which I had to use smaller ones. Snyders pads are ever so slightly thinner (not by much) PLUS they are more flexable and thus allow the original nuts and bolts to close up more to get the right size cotter key into the holes.

Re: Engine replacement problems
My last set of rubber pads came from Snyder's and fit perfectly. I've only had to use a frame spreader twice, and come to think about it, that may have been caused by the new rubber pads being a hair too thick. I like to put a thin coat of grease on the mounts to help the flywheel cover slip into place.

Along with the better pads. Put a little grease on the end of the mounts. This lets it slide in there a little easier. |

Re: Engine replacement problems
Thanks for all the info. The mount pads were from Snyders. I will try a little grease and remove the mount if needed. Maybe I will have better luck tonight.

Re: Engine replacement problems
Tom, I had tight motor mounts and took a 4" grinder and rounded off the corners of the mounts and the corners of the bellhousing also greased them. A club member told me that sometimes if you put a jack between the motor mounts and jack it out and then remove the jack it will stay spread long enough to push the motor in.

Re: Engine replacement problems
If absolutely needed just put a small jack with appropriate wooden blocks, at least 2x4 across the frame and spread the frame outward (Jack open the frame.)

Re: Engine replacement problems
Tom
As Tom w. said a little grease on the leading edge helps a little I've also used a 2x4 about 3 ft long and once the engine is at the entrance to the mounts used it in a vertical with the lower end on the driver side front crossmember putting pressure at the timing cover area. It helps push it in the mounts I have done many . The new frame spreaders do help if you have access to one . It doesn't take much though I disagree with the frame sag post above causing the problem . With new rubber in the mounts the install is snug normally No sweat. Just takes a little to get it in If you don't have the frame spreader try the leverage of the 2x4 Larry shepard |

Re: Engine replacement problems
I usually borrow my friend Charley's frame spreader.
