I have acquired a 239 yblock and would like to switch pulley over to a 292 - 56 ford type pulley. It looks like it should switch but not sure what it requires or if it will even work. Advice appreciated...Whipper

All the Y-Block dampers will interchange on the '54-'64 engines; crankshaft and seal dimensions are the same. You will have to watch out for outer clearance issues at the front mount on some of the earlier engines; some of these had the smaller diameter dampers which may require a later model front mount to go along with the later model damper. That's assuming you are working with an application that requires a front mount. You didn’t mention if this was a truck or car engine which will have some differences in belt pulleys. In these cases, the water pump pulley will also need to be changed out.

I believe it is a 239 from a 1954 Ford auto. I have old 292 which I could take front cover off and use. I will check and make sure pulleys line up. Should I change seal, I assume they are same?

If the timing cover seal is aged or looks to have been leaking, this would be a good time to change out that seal. That seal is the same for all years.

Thanks Ted, I have that cover gasket but I mean the seal that goes in cover housing that goes around crankshaft. I believe part no. 6700 or close to that, I do not see that part listed in my catalog so I wonder if it has to be changed. Ok Roger I just saw your post and right it probably best to change that seal if I can get one. Do you know if that seal is in a overhaul gasket set?

If you are using the steady rest (car) for a 54 239, the 292 damper will not fit. You have to either leave it off or use a 55-56 steady rest. I found this out when I put a 312 in my 54.

Yes, I have a 56 steadyrest. I am putting 239OHV in my 56 Vic. The crankshaft pulley on 239 is smaller and comes off ok but still another piece that has to come off crank on keyway that I can`t seem to move. I don`t want to break anything, Do you have any suggestions what might be making this stick. I am trying to install 56 pulley on crankshaft..

Not sure what piece you are talking about that is remaining on the crankshaft. The ’54 damper when removed should leave the crankshaft fully exposed so that the later model damper can be installed. Can you post a picture?

Ted, mine is a 239 car engine in the truck. There's a steel spacer that went over the crank snout first, then the pulley. Pulley is shorter than a dampner.
The seal rides on that spacer. The spacer just slides on and off, nothing holds it except the crank snout bolt.

SUCCESS. I finally got that piece off of crankshaft. It was a spacer and with a little persuading I finally got it to slide out. Thanks Ted and Pintoplumber for advice that got my problem solved, and to all who commented. I have another problem but I will see if I can figure it out. Thanks again...WHIPPER.

Dennis. Thanks for the info on the crankshaft sleeve that’s separate from the belt pulley. That sounds like it’s similar to the marine engines where they also have a crankshaft seal sleeve that goes in place before the pulley is installed.

That's exactly what I have but could not get that sleeve to budge until you guys gave me the info. (PS. Ted, I would have posted a picture if I only knew how.)
