Oil Pan and Drag Link Interference 8BA in 36 Cabriolet 3 Attachment(s)
This is my first post - 36 Cabriolet with an 8BA engine and 1937 steering box. See attached pictures.
I think my oil pan is from an 8BA truck engine. Can anyone verify this from the pics below? My drag link has been modified to clear my oil pan. When I hit a bump in the road, it clanks pretty loudly. If it breaks, it's a serious safety issue. I would like to find an oil pan that would allow me to install a straight, unmodified drag link. Is that possible? Will an oil pan from a passenger car 8BA, 59AB, or earlier flathead engine solve my problem? I think the early flathead engines had a road breather opening in the oil pan. If I found one of those and welded the breather shut would that work? Will any non-8BA oil pan accommodate my existing oil pump and pickup? Thanks for your thoughts and advice. |
Re: Oil Pan and Drag Link Interference 8BA in 36 Cabriolet I put an 8BA in my '36 3-Window about 30 years ago and don't remember having to modify the drag link at all. I think I used a Merc pan as well. It could be that the front of your engine is too low. I seem to remember that Hurst and others made spacers to go under the water pumps and raise the front of the engine. I know I used them.

First off, an early (pre-1949) oil pan will not fit an 8BA engine because of the added REAR portion which is designed to affix the early ('32 - '48) transmissions to. And, your particular problem of the drag link interfering with the front portion of the sump is not unheard of. Some '36s with 8BA have no problem with the drag link clearance at pan, while other DO. I have researched this random problem over the last few years and can only come to the conclusion that it likely depends on how high or low the 8BA engine is mounted at the front crossmember mounting points. This particular '36 3-W coupe equipped with an 8BA, and which also runs the same pick-up oil pan as you do has no problem with the drag link clearing the pan. In fact, this particular '36 even has a later '40 steering box (same as your '37) ..... see picture BELOW. https://www.fordbarn.com/forum/attac...2&d=1497324932 The only real solution that I have seen for this problem is the welded-in piece seen in this identical oil pan BELOW, belonging to someone that obviously had a similar problem. That's all the help I can provide. Coop https://www.fordbarn.com/forum/attac...9&d=1609442870 |
Re: Oil Pan and Drag Link Interference 8BA in 36 Cabriolet The best fix is a 49-50 Mercury pan & pickup.
It works! |
Re: Oil Pan and Drag Link Interference 8BA in 36 Cabriolet Thanks for the quick replies of info and advice. I will look at shimming my front motor mounts first. I think my motor is slanted down in the front right now. If that doesn't do it I'll try to find the merc 49-50 pan and pickup next. Last step will be to modify the pan as suggested. I'll be back with an update of what worked for me. Thanks again Ford Barn Men.

All Hurst motor mounts were made to work with '41-'48 Ford frames. To use them in other frames (earlier or later Ford and even Chevrolets), they supplied frame adapters that made the other frames an analog of the '41-'48 units. The frame adapters for '35-'40 were spacers that raised the engine significantly. If you are using later Ford truck pumps, your engine is sitting too low; if you are using late Mercury pumps (they fit and have similar mounting ears), it is sitting waaaay to low. Find out what you have for water pumps and I can give you some advice.
I'll see if I can find and post the Hurst mount information. EDIT : All I could find in a hurry is this catalog page. Unfortunately, it has been truncated. However if you look in the top right hand corner, you will see the adapters needed to make a '35-'40 frame look like a '41-48. Since an 8BA with truck pumps fit the '41-'48 frame, you will need these spacers or something similar (I made mine out of 2" square tube). Whoever did that nice fabrication on that oil pan Coop shows should have done his homework first. BTW, the large "cleanout" in your pan inducates a late truck pan. It should work fine if you can get the engine where it belongs. |

Frank ..... I would be cautious about your intention to source a '49-'50 Merc pan and pickup. I've considered the Merc parts as a possible cure for the problem, but without trying it on one of these problem cars myself to see if it does actually rectify the problem, I MYSELF wouldn't guarantee the Merc parts as an absolute solution. I mention this as you will soon learn that the Merc pans are pretty damned rare now-a-days, but the corresponding pickups are harder to find than hens' teeth and will shock you when you see the price tags on them. When they do appear on "the 'Bay", they are usually priced in the $400 range or higher. I believe I'd be modifying the front of the sump on your existing pan. Coop Here are pics of the Merc pan and pickup BELOW! https://www.fordbarn.com/forum/attac...4&d=1596643741 https://www.fordbarn.com/forum/attac...0&d=1596650468 https://www.fordbarn.com/forum/attac...9&d=1596650441 https://www.fordbarn.com/forum/attac...9&d=1596650441 https://www.fordbarn.com/forum/attac...8&d=1596650415 https://www.picclickimg.com/00/s/MTI...ad-Ford-_1.jpg |
Re: Oil Pan and Drag Link Interference 8BA in 36 Cabriolet Coop, I gotta ask; did you read my post? Everybody is complicating what is quite simply an easy fix.
He even says he "thinks his motor is slanted down". You know that ain't right. |

What about using the late Mercury motor mount spacers to raise it up.

Remember, there is always a chance that late model Merc water pumps were used. If so, the mounting pad is even higher and even higher spacers are needed. |
Re: Oil Pan and Drag Link Interference 8BA in 36 Cabriolet I have to question myself with this , early 1970s I slid a late 8ba in my 36 I do remember the only itch was the fan but I did it with no problem 'with a truck pan'...

I have the Hurst spacers in my 40 with a SBC :-()
The pdf is the literature that I got with the Hurst part SP-150 https://www.fordbarn.com/forum/attac...1&d=1689856428 Glenn |
Re: Oil Pan and Drag Link Interference 8BA in 36 Cabriolet Glenn, thanks for posting that. Now I don't have to spend my afternoon looking for a complete copy.:)

Re: Oil Pan and Drag Link Interference 8BA in 36 Cabriolet Glad to help :)

The common method to mount an 8BA type of engine in an early chassis, ie; '36-48 is to use '49-50 merc pumps and/or truck pumps with the '49-50 merc spacers under the pumps to allow for the offset of the mounting bolts and shortness of the pump mounts. I would also suggest that you get a car pan in lieu of the truck pan you have. |
