Nippondenso Hino Truck 1995 Service Manual

You’ve got a Hino truck in the bay with an AC system that’s been converted to R-134a, but the pressures don’t match the sticker under the hood. Maybe someone swapped parts without checking the retrofit specs. That’s where this Nippondenso Hino Truck 1995 Service Manual comes in — factory documentation for the air conditioner retrofitting procedure, written by the people who built the system. Not a generic aftermarket rewrite. Nineteen pages of what you actually need: recharge pressure limits, compressor oil volumes, O-ring sizes, service tool part numbers, and the exact order to pull the shaft seal on a 10P13 compressor. If you’re working on a Hino truck with an AC system that was originally R-12, this is the supplement the factory put together to get it running on R-134a without blowing a line or seizing a compressor. I’ve seen too many hack jobs where a guy guessed the oil charge and trashed a receiver. Don’t be that guy.

Maintenance Procedures for R-134a Recharge and Oil Replenishment

Chapter 1 lays out the recharge conditions in plain numbers. Ambient temperature at 15°C (59°F) gets you a high-side pressure of 0.8 MPa (114 psi). At 35°C or over, you’re looking at 1.4 MPa (199 psi). Those are the limits with doors open, max cool, fan HI, engine at 1500 rpm. Miss those numbers and you’re either undercharged or overcharged. The manual also gives the recharge amount in grams and ounces — but you’ll need to cross-reference page 30 of the main Air Conditioner Retrofit Manual for the exact gram count per truck model. Oil replenishment is per compressor type: 10P13 gets 70cc into the receiver, 70cc drawn into the cycle, total 140cc of ND-OIL8. 2M110B takes the same amounts. That’s straight from the factory, not a guess from some forum post.

What Tools Are Required?

Flip to the service tool list on page 2 of the manual. You’ll need a magnetic clutch stopper — ND part number 95047-10040 for conventional type or 95047-10331 for current type. A magnetic clutch remover (bolt type) is part 95047-10060. Key remover 95042-10160 and key replacer 95042-10190. Snap ring pliers internal type 95994-10010. If you don’t have those, don’t try prying the clutch off with a screwdriver. You’ll bend the hub and then you’re ordering a whole compressor instead of a $15 seal kit. Nippondenso R1.4 R2.5 1998 Service Manual – OEM Starting Motor Specs uses similar specialty tools for starter disassembly — same philosophy: use the right tool or walk away.

Compressor O-Ring and Shaft Seal Replacement (10P13)

Chapter 2 walks through the seal replacement step by step. You pull the magnetic clutch using the remover, then use the key remover to pull the Woodruff key. The snap ring pliers get the internal snap ring out. The shaft seal comes out with a seal puller — the manual doesn’t list that part number, but any ND-approved tool works. New O-rings go in with refrigerant oil applied, not grease. The torque for the compressor shaft nut? Not listed here — that’s in the main retrofit manual. But the 19 pages cover what’s specific to this Hino truck. Don’t skip the O-ring sizes; they’re in the retrofit parts list (Chapter 3) with ND part numbers. If you use the wrong O-ring, you’ll have a leak within a month. I’ve seen it.

3 Retrofit Parts You’ll Need from Chapter 3

Chapter 3 gives the exact part numbers for the receiver, rubber spacer, shaft seal, O-rings, service valve fitting, and the caution label. The receiver is specific to this retrofit — it’s designed for R-134a desiccant. Don’t reuse an old R-12 receiver; the desiccant grains are different and will clog your expansion valve. The O-ring kit covers multiple sizes; you’ll see the ND numbers in the table. Service valve fitting adapts your manifold gauges to the new service ports. The caution label (“R-134a only”) goes on the hood so the next tech doesn’t pump in R-12 and grenade the system. White Outdoor LT-5 700 Series 2005 Service Manual – OEM Factory Specs also uses caution labels for safety-critical fluid changes — it’s a habit worth copying.

Foreword and Scope: What This Supplement Does

The foreword states clearly: this is a supplement used in combination with the main car air conditioner retrofit manual (990005-0270). That main manual has the theory, the general procedures, and the torque specs. This 19-page booklet fills in the specifics for Hino trucks — the compressor setup, the brackets, the hose routing. If you only buy this supplement and expect to learn how to retrofit an AC system from scratch, you’re missing the foundation. Pair it with the main manual. I recommend getting both from AutoRepairManuals, but this one alone gives you the truck-specific data that the main manual doesn’t have. If you’re doing a Hino truck, this is mandatory reading. Maruti MB308 Service Manual – OEM Factory Specs for Proper Repairs also follows the supplement approach for engine-specific data — same idea, different vehicle.

Is There Any Torque Data in These 19 Pages?

No torque values are printed in this supplement. The manual directs you to page 30 and page 27 of the main retrofit manual for recharge and oil details. For compressor mounting bolt torque, you need the main manual. For the shaft seal nut, same. That’s not a flaw — it’s intentional. The supplement assumes you already have the base manual. If you don’t, you’re working blind. Don’t guess torque on a compressor; strip a bolt and you’re replacing the whole unit. Manual Transmission repair manuals have the same structure — a base volume and vehicle-specific supplements. Know what you’re buying.

Does this manual cover the 10P13 compressor?

Yes.

Can I use this manual to retrofit a Hino truck that already has R-134a components?

If the truck was originally R-12 and someone swapped parts without following factory procedure, this manual’s recharge pressures and oil replenishment tables still apply. However, the installation instructions assume you’re starting from an R-12 system. If the system is already R-134a but pressures are off, use the recharge data on page 3 and the oil specs on page 4. For seal replacement, the procedure is the same regardless of refrigerant type. Just verify the O-ring part numbers match what’s installed. The caution label should already be there; if not, install it. The main limitation is that this manual doesn’t cover component diagnosis (bad expansion valve, clogged orifice tube) — for that you need the full AC retrofit manual.

You need factory data to do this job right. The aftermarket side of my toolbox is full of burned-out compressors from incorrect oil charges. This 19-page Nippondenso manual stops that nonsense. Manual Transmission documentation has the same level of precision. Don’t trust a PDF that says “refer to vehicle-specific data” without giving it to you. This one gives it. Access the Factory Manual and get the Hino’s AC back to factory spec.
