crank gear oil slinger on a 292 Thunderbird engine.
Is there supposed to be an oil slinger before or after the crankshaft gear on a 1955 Ford 292 Thunderbird engine? It looks like someone may have put one behind the crank gear and it is destoyed metal hopefully not any other damage like to block or crank itself or bearings from heat.Is this gear with the cam gear a press on or will it pull off easy?

Re: crank gear oil slinger on a 292 Thunderbird engine.
The oil slinger goes on the front side of the crankshaft timing gear. Not sure how one would even fit behind it.
The timing gear(s) should slide off together after removing the bolt at the front center of the cam shaft. The fit past the woodruff keys on the crank may/may not be a little bit snug. Keep all the small pieces from the front of the cam gear in order so they go back on correctly. Last edited by dmsfrr; 08-28-2022 at 06:54 PM. Reason: add image |

Re: crank gear oil slinger on a 292 Thunderbird engine.
Thanks Dennis. I wonder if this is a part that was not used until 1956 292 engines ? Reason I say this is my parts book dated November 1954 Form 7516 does not show this slinger in Thunderbird crankshaft exploded view.When I look on Ebay they show the slinger with a B6A prefix most parts in my 1955 book prefix with B5A so maybe the B6 means this part was introduced in 1956.Couple of my Ford repair manuals do not mention the slinger like the 1955 Ford repair manual. So now I wonder if the guy who put this on wrong had nothing to go by an just put the slinger behind like on Flathead Ford engines. I just hope it created no other damage other than to the slinger. I have been trying for three months now to figure this car out with no prior history to lean on. Car was bought from estate.Someone years ago put new plugs ,anitfreeze,oil and filter on this engine and never ran it long.I can tell because everything is clean as new,plugs are new but sooty. I think it started made noise with slinger being chewed up and guy shut it down and walked away from it like I hope I don't do,just wonder what else I will find,probably should pull the engine and go through it but thought I would go this way first,all started with misaligned crank pulley/balancer and then crank seal replace but lucky I guess pulling timing cover and seeing the slinger tore up beteween block and cranks gear. I do know this about previous owner,he was a Thunderbird/'55 Ford car restorer by trade in Ohio.

Re: crank gear oil slinger on a 292 Thunderbird engine.
If you put the oil slinger on backwards, the crankshaft damper hub will crush it against the lower timing chain sprocket. The photo dmsfrr shows the oil slinger installed correctly.
I don't see how anyone could install it backwards as it is easy to see the crankshaft damper hub wouldn't go on all the way with it installed backward. They must have torqued the crankshaft damper bolt to the max to crush that oil slinger. |

To further the mystery, the close-up first photo in my reply # 2 above (bigger version below) shows the slinger in a '54 256 Merc engine, block & heads with an EBY casting number prefix. Noted that the engine wasn't original to the car it was removed from. There was also a front oil slinger on the crank in the mostly '55 long-block engine I bought from another T-Bird to replace the 256. Last edited by dmsfrr; 09-02-2022 at 10:41 AM. Reason: add photo |

Re: crank gear oil slinger on a 292 Thunderbird engine.
Okay so all of the help has been great but I have one more favor to ask. On the camshaft timing gear/fuel pump eccentric parts it looks like I am missing one part.Now again I am going by my November 1954 form7516 parts book. I am missing either the washer EAA-6278-B or maybe it is the spacer B4A-6291-A and maybe how they are placed in respect to the eccentric or its counterweight.Thanks

Re: crank gear oil slinger on a 292 Thunderbird engine.
Do you have the counterweight or a keyed spacer like this one? It's one or the other.
The counterweight or keyed spacer goes on first, against the large cam gear, then the eccentric ring. Next is a round un-keyed spacer then the bolt with a lock washer and large-ish flat washer. Last edited by dmsfrr; 09-02-2022 at 10:45 AM. |

Re: crank gear oil slinger on a 292 Thunderbird engine.
counterweight. Another confusion if parts book shows both in exploded view. So I am okay with just the counterweight?

Re: crank gear oil slinger on a 292 Thunderbird engine.
Yes. The counterweight was discontinued in '57 (?) in favor of the keyed spacer. Most likely due to the cost savings.

Re: crank gear oil slinger on a 292 Thunderbird engine.
In mid-1956 production, the FYB saw many changes. The CAM DRIVE (among other changes) was updated. The slinger was not used before this change (subject to TED EATON's opinion). There was a drip tray that diverted supplied oil to the chain directly. This was eliminated and as a result of the chain being lubed off of splash, the slinger was necessary to keep oil off the front seal.

It seems to me that I would want the slinger on the setup if it will fit within the crank gear/crank snout. It may be FORD engineering missed this at first design and/or realized the importance to add. To add is a question for TED EATON as he is the FINAL WORD (IMO) on this type of FYB modification(s). I am not qualified to make that call. He will take your E-MAIL, PM or you can post it on his site. - http://forums.y-blocksforever.com/default.aspx - Hope that made sense and helps.

Sorry about that. They have a restricted entry due to spamming -

Re: crank gear oil slinger on a 292 Thunderbird engine.
Okay got another Y block Question.On the front of the timing cover and where the four hex bolts attach to the front engine support why is four bolts 3/8" threads and the one out of the four is 5/16" . You think all four would be the same.

Re: crank gear oil slinger on a 292 Thunderbird engine.
Is the engine in a FORD or BIRD?

The hole in the mounting bracket at center left does not go into the timing cover or block and is / can be used as a generator mounting bracket attaching point. Last edited by dmsfrr; 09-02-2022 at 05:33 PM. Reason: add photo |
