Re: 1951 Ultramatic

I have been thinking about this for a while for my 1953, to the point that I have acquired an extra NOS cap for the purposes of modification. It's simply a matter of paranoia - I don't drive it THAT often, but I want to be able to quickly ascertain, both before and after the drive, how it is doing. Piece of mind.

I have found that I can top off my unit from the engine compartment using a piece of flexible hose about 36" long not including the funnel. I haven't yet figured out exactly how it should be mounted to the firewall or the engine or?. See the attached photo.

To make a dipstick work, the "dipstick portion" should protrude past where it screws onto the modified cap about 4.5", See the attached photo.

For my '53, I spent some time on the phone talking with Lokar technical support, thinking one of their locking dipsticks might be perfect. However, the Lokar rep was not enthusiastic, for mainly one reason: their locking dipsticks are not designed to protrude past the screw-in section anywhere near 4.5" long.

I don't think any of those considerations are really a big deal if one moves to the non-locking version. From what I can tell, Lokar is using standard hydraulic hose and fittings for their center sections (available in numerous lengths including 36" and 48"), and for their standard, non-locking dipsticks, they sell optional decorative knobs, which implies that the knob can be replaced. In addition, the Ford C4 "pan" style dipstick already screws in, and has a nice curve in it, which would probably work nice for where the existing dipstick location is on the 1953 (see attached photo), but as I do not know the exact radius required it would need some additional measurements.

In addition, the Lokar stuff all uses from what I can tell standard reusable hydraulic hose fittings, which means that the hose can be taken off and shortened, or a longer hose substituted. For the standard non-locking dipsticks, Lokar sells "deluxe" handles, which means you can take the stock handle off and change the length of the dipstick to get the correct position within the car.

So what this says to me is that one could order a 48" long Lokar C4 pan, create a fitting to attach it to the top of the donated cap, and then shorten the dipstick and hose to an appropriate length.

Have I done it yet? No, I have not. Waiting to get engine back in car first, and still thinking whether Lokar or another vendor, or whether the idea really has merit. Lokar does have a pretty responsive technical support line at tech@lokar.com, maybe they would respond positively to someone else.
