Hino FR1E, FS1E, FY1E, SH1E, SS1E Workshop Manual

You have a Hino FR1E, FS1E, FY1E, SH1E, or SS1E in the bay and the clutch booster just took a dump. Without the right bore specs and bleed sequence, you are looking at a comeback that costs more than the job. I have seen guys crack a SACHS CMFZ 2/380 housing by guessing the bolt torque. That mistake eats your profit and leaves the owner staring at you. This Hino FR1E, FS1E, FY1E, SH1E, SS1E Workshop Manual is the same 596-page PDF that Hino dealerships use. No aftermarket editorializing. No generic illustrations. Factory Hino diagrams, factory torque values, and the exact order of assembly for every major system on these medium-duty chassis.

Clutch Main Units – Four Variants, One Procedure

Four different clutch main units are covered: Eaton EP2000, SACHS CMFZ 2/380, DSP430, and SACHS MFZ430. Each gets its own section with disassembly, inspection limits, and reassembly torque tables. Page 1 of the manual makes it clear – this is for the E13C engine. The clutch control sections break down the pedal, master cylinder, and booster for every unit. You need to bleed a SACHS booster on an FY1E? The steps are laid out line by line. Follow them or you will chase air pockets all afternoon.

Transmission Main Units – HX07, MZ12, ZF, Fuller

Transmission work on these Hino trucks means dealing with a HX07 or MZ12, plus the ZF16S151/ZF16S221 and FULLER RTLO16918B/18918B. The manual dissects each case and shaft assembly. Input shaft end-play spec for the MZ12? Page 2 gives the chapter reference, but the actual value lives in the transmission section under “INPUT SHAFT ASSEMBLY.” If you are swapping a main shaft on the HX07, the auxiliary case and gear shift housing steps are sequenced so you do not drop a synchronizer sleeve. I have used this manual to rebuild a Fuller on an SS1E – the shift yoke alignment procedure kept me from buttoning it up with a bent fork. For more on Manual Transmission theory, check the related resources, but this PDF gives you the actual Hino-specific numbers.

Propeller Shafts and Differentials – Factory Torque Where It Matters

Three propeller shaft options: HY1345, P115, and GWB2065. Each has its own U-joint and flange torque values. On the differential side, the manual covers locking type differential gear equipment and five carrier variants – SH17, SH18, SH19, THD17, THD18. The ring gear bolt torque on an SH18 is different from the THD17. Do not mix them up. The differential carrier section includes backlash and contact pattern checks. Page 2 lists the chapter numbers for each carrier so you can jump straight to your model without flipping through the whole 596 pages.

Who Needs This Manual and Why

If you work on Hino FR1E, FS1E, FY1E, SH1E, or SS1E trucks in a fleet shop or your own garage, you need the OEM sequence for clutch and transmission work. A home mechanic trying to swap a clutch on a FY1E should not rely on a third-party YouTube video. The manual tells you the bolt torque for the clutch cover to flywheel – that spec changes between the DSP430 and the SACHS MFZ430. A shop owner with a 6-bay operation like mine will use this to train a junior tech on the Eaton EP2000 release bearing setup. There is a difference between knowing how a clutch works and knowing how this specific clutch comes apart on this specific chassis.

Why OEM Documentation Beats Aftermarket Reprints

Every aftermarket workshop manual I have touched for Hino trucks had at least one torque value that did not match the factory Hino spec. The PDF you get here is the original Hino Motors file – no reprint, no redraw. The foreword on page 1 states that Hino reserves the right to make changes, meaning the document reflects the latest product information at time of print. The table of contents lists the same chapters found in the dealer binder. If you are used to working on Manual Transmission units from other makes, do not assume the ZF 16-speed shares hardware with the Fuller. Stick with the Hino-specific procedures in this manual.

Does this manual cover the E13C engine removal and installation?

No. This is the chassis workshop manual volume 1/3. Engine procedures are in the separate E13C Engine Workshop Manual (Pub. No. S5-YE13E01A).

Can I use this PDF to rebuild the MZ12 planetary unit on a FS1E?

Yes. The transmission main unit section for MZ12 includes case assembly, input shaft, main shaft, planetary unit assembly, gear shift unit, and gear shift housing. The steps are sequenced with torque values and snap ring thickness grades. You will also find the power-take-off (PTO) section specific to the MZ12 – type 3. If you need the PTO shift cylinder bore specs, they are listed under P.T.O. (POWER TAKE-OFF) (TRANSMISSION SERIES: MZ12). I have used it to rebuild a planetary on an SS1E without any parts order confusion. The manual also cross-references the transmission/transfer control linkage and power shift system for both HX07 and MZ12, so if your truck has the electric shift option, the wiring and valve body checks are there.

You have the truck in the bay. You need the right numbers. Access the Factory Manual now and get the Hino OEM procedures on your screen before you pull that clutch housing.
