Default Hercules RXLDH engine out of 1948 Pirsch fire truck?

I just removed a stuck 558 cubic inch Hercules RXLDH flat head 6 cylinder out of a 1948 Peter Pirsch fire truck. Where in the world can parts be found? The engine is stuck from sitting for a long time in humid Houston, TX. I can see moisture on the dipstick. I'm certain I will need at the very least gaskets and probably piston rings. The truck was the typical low mileage fire truck. The fire truck was sold and the guy that bought it was going to throw the engine in the trash. I couldn't let the engine go to scrap.

Well, gaskets can come from gasketstogo, a sponsor here (click on "sponsors" at top of page) or olsonsgaskets.com in Port Orchard (assuming NLA thru local sources)...
Rings are pretty well a commodity item, unless you have some weird and wonderful oddity rings--unlikely with a Herc--- see the sponsors page again......
The RX series seems to've run from RXA thru RXC, jumping to RXL, with numerous variations...will post more in AM, with some places to try (assuming internals NLA as above)...(getting late here, past my bedtime)...

Jerry Biro is North America's largest dealer for obsolete Hercules engines. He is in Ohio. I will look for his number over the weekend. Do you have the engine apart? I can decode the model number except for the H.

I had a 1946 Diamond T 404 with a Hercules CBJXE and got all the parts from NAPA. Rings, .010 under rod and main bearings, cam bearings, ring grove shims, and overhaul gasket set....

As John said, start with Jerry---there's also Herculresengine. com (engine singular; if you put in engines (plural) you get the website for Herc 1cyl farm engines)...there're also the profe$$ional obsolete engine parts dealers...jobbersinc seems to have a tremendous inventory, with comments that they seem to care the very most about their parts...
I'm not sure about decoding--Hercs QXLD is a longer stroke version of QXD, as their WXLC is a longer stroke version of WXC---but my catalogs say ALL the RX's are 51/4 stroke...the "H" is apparently a hi-power version per a Herc folder I believe John sent me---will post specs later, hurried this PM...
Hercs JX series, at least JXA-D, were built to same outside dimensions, so engines were drop-in fit for each other; don't know if same true for the RX's...
Looks like introduced around 31-33; looks like fair penetration in over-the-road trucks, enough that should be market for it (altho not as popular as JXs, QXs or WXs)...don't have much on other eqpmt, will eyeball what I have...
Looks like nice save, even if too expensive to restore, will probably find a home for the block/parts...

/from a 1940 Hercules Operator's Handbook for WX,YX,RX and RXL series. RXLD is 4 3/4 X 5 1/4. Oil cap is 13 qts in RXL series, No info on the "H", but suspect it is a "heavy" duty engine model. Your engine appears to have dual oil filter cans. Pics in the handbook don't have a second oil filter. Handbook indicates that the RXL has aluminum alloy pistons and five rings per piston. If you are interested in a copy of the handbook let me know.

RXLD/RXLDH (in that order) specs from John S's Mar 1957?? Herc Brochure:
B/S/CID---both 43/4x51/4, 558
Max Torque---430/1100, 443/1400
Dyno BHP, stripped, full throttle
800---65/64 (no typo)
1000---82/83
1200---98/100
1400---112/118
1600---126/133
1800---137/146---1800 also noted as max speed for continuous service under full load for both...
2000---145/158
2200---151/167
2400---154/175
2600---blank/181
2800-3200---all blank (disintegration at 2600/2800???) (joke??)...
Remember to ask any parts dealers if they know if the RXs made with same exterior or even same mounting specs; if this will fit into RXA/B/C installations will vastly widen prospective market...

I don't have an RX manual, but if the RX engines are like the other series of that time we need to determine if they made them in RX# and RX5 basic versions too. Do you have the engine apart? Bud: send me an e-mail, please.

No, I don't have the engine apart yet. I have only have time to remove it from the fire truck and get the transmission off of it. I poured diesel in the cylinders. I plan on taking it apart in the next week or so.

You should consider trying to get the engine free before taking it apart. I've freed up several engines and got them running again without ever dismantling them.

JB: On the question of whether the RX's all made to same exterior dimensions, try Landis Zimmerman at olivercletrac.org...the Cletrac DG, apparently for 1937-38, used an RXC, and those Cletrac owners might've checked to see if another RX would drop in...
Per my old catalogs series seems to run:
RXA---don't really know if this engine exists; I only have one mention, in 51 Fed Mog brg catalog, lumped in with RXB/RXC, bore indefinite, but if exists might be 43/8...
RXB---41/2
RXC and variations---45/8
RXL, RXLC, RXLC3 (only listing with number) RXLCT---also 45/8
RXLD, RXLDH, RXLDT---43/4...ALL RX strokes shown as 51/4...
Alum pistons are listed in one catalog for RXLD, as mentioned above, but catalog inimplies some used grey iron pistons (a number of other Hercs are listed with both alum and grey iron)...
There were "early" and "late" versions of RXB/C---poured and insert brgs, but may be other internal updates. None specifically mentioned for RXLD, but possibly implied in some listings...
So far earliest truck installation 1931 for RXB and 1932 for RXC; RXLD doesn't show up until 1941, seems to run to at least 1953. 17 makes, only 4 also using RXLD---will advise further later...

I've decide that I have far too many project sitting on the floor of the hangar right now, so I'm going to sell the Hercules RXLDH engine outright. I haven't had time to take it apart or to examine it any further. If one of you wants it, I'll take $450. The engine is stored in Alvin, Texas, 77511.
I also have a non running R-3350 radial engine that makes over 3,000 horsepower that needs to leave as well. The radial engine appears to have been rebuilt, but it is missing the fuel injection system and other accessories. It makes an awesome 3000lb dead weight display! $2600 for the radial engine. It is the same basic engine as used on B-29s.

Dang... wish I had an assignment down your way, I'd find a way to stuff the Herky in my truck.

I'll second the prior post re. breaking it free... I've got a JXLD (339ci?) that was stuck when I got it... I pulled the lid off, found that it had one stuck valve... I shot it with some PB and rapped on it a few times with a wood-headed mallet, and it freed up, turned over nice, and started right up...

Oh the sound... they sound wonderful.

As for the radial... slide it back about 26", and bolt it down solid, the prop will hang out the back just far enough to clear the tailgate... and don't toss any litter out the window! ;-)

The radial engine has left to a new home, but I still have this Hercules engine sitting in the middle of the floor. It needs to find a new home soon.

The Hercules engine sold a while back and is now somewhere near San Antonio.

Hey there,

I need to replace a 558cu RXLDH and found the same motor but without the H. Does anyone know what the difference is between the two? In the post someone guessed it may have been "H" for Heavy?

Will the RXLD fit into the transmission?

Justin

Hi guys I have the rxldh that Jason sold it's currently sitting I have begun the process of unsticking it. Took head off and number 3 cyl got hit the hardest. From the research I did the rxldh and rxldh are the same block heads etc the only difference is the h stands for high speed which is 2700 rpm where the rxld was rated for 2100. I'm guessing this was to allow it to operate at highway speeds as a freight hauler. Any other questions I will be glad to answer.
