The Toyopet Master , introduced in January 1955, is a passenger car that was an evolution of the earlier Toyota SF/RH sedan (also known as the Super) with a modernized body. As with its predecessor, the Master has a ladder frame truck chassis with leaf sprung solid axles both at the front and the rear. The more conservative Master was sold in parallel with the first Toyota Crown as a frugally equipped and robust version meant for taxi usage. The Master and Crown shared the same R-series engine, which produces 48 PS (35 kW) in the Master. It was sold at a chain of Toyota Japan dealerships called Toyota Store , next to the more upscale Crown, which was intended as a private purchase alternative to the Master.
39-579: In 1955 Toyota wasn't sure if its independent front coil suspension and the rear-hinged back doors installed on the Crown wouldn't be too radical for the taxi market to accept. When sales of the Crown proved satisfying, the Master sedan was discontinued in November 1956. The Master's body was built by Toyota's Kanto Auto Works subcontractor, as with the preceding RHK Super model. Along with the perceived need for
78-551: A KKK turbocharger , the Group 5 Celica developed 560 PS (412 kW; 552 hp) but reliability was less than satisfactory. Applications: The 2-valve SOHC 2.0 L (1,968 cc) 19R was produced from 1974 through 1977. Cylinder bore and stroke was 88.5 mm × 80 mm (3.48 in × 3.15 in). Its dimensions are the same as of the 18R, but it featured TTC-V , Toyota's licensed version of Honda's CVCC stratified charge combustion system. Output
117-467: A Toyota contractor, producing auto bodies. During its early years, the company also assembled some cars for Toyota ( Toyota SB , Toyota Master , Toyota Crown ). The company also diversified into other products such as yachts and prefabricated homes . In 1950, it adopted the Kanto Auto Works name. In 1960, the company became a permanent car assembler through a new Yokosuka plant. Later,
156-399: A 7.7:1 compression ratio. In 1960 the 3R was uprated to 8:1 and the 3R-B version was offered from 1960 through 1968 with the old 7.7:1 compression ratio. The 3R-C was introduced to comply with California emissions laws. The 3R-LPG variant was produced for the last five years. Applications: The 1.6 L (1,587 cc) 4R family was produced from 1965 through 1968. Bore and stroke
195-481: A balance tube. Toyota upped the ante again with the DOHC (but still 2-valve) 8R-G , produced from 1969 through 1972. From 1969 to Feb 1971 it was known as the 10R , but along with a removal of the tensioner gear in the interest of quieter operation, it was renamed the 8R-G to reflect the decision that twin-cam engines were henceforth to be identified by a "-G" suffix. 4,931 twin cam engines were built, all installed in
234-505: A more robust and conservative model for professional users, Toyota was also interested in providing Kanto Auto Works with assembly work to make up for Toyota moving the production of the Crown entirely in-house. Project Manager Tozo Yabuta quickly developed the Master using a large number of the RHK's parts, with the first prototype running in March 1954. One seemingly retrograde step was moving from

312-781: A single-cab pickup and a van. These replaced the SG commercial models and were the first car-based trucks to enter production in Japan. The chassis were built at Toyota's main Aichi plant and then transported overland to Kanto Auto Works in Yokosuka, where the bodies were assembled mainly by hand. The double pickup was added in August 1956, around which time the engine was upgraded to provide 55 PS (40 kW). By 1958, power had been increased again, reaching 58 PS (43 kW). The double cab pickup
351-536: A two-door Light Van (RS17) were offered, also available with left-hand-drive. The engine was the same 48 PS (35 kW) R unit seen in other Master models. Later in 1956 a two-seat pickup version also entered lists, with the RS19 chassis code. When the Crown passenger car was facelifted, the Masterline nameplate was moved to the commercial versions of the Crown. This meant independent front suspension coupled with

The all-new RS46 Toyopet Masterline arrived in October 1962, using the same 80 PS (59 kW) 1.9-liter 3R engine as the previous RS36 models. Bodystyles included a pickup (RS46), a double-cab pickup (RS46P), and a four-door light van (RS46V). The two-door van bodystyle

While most 18R-Gs had a head designed and made by Yamaha , a very few had Toyota heads. Yamaha's tuning-fork logo can be seen on the Yamaha heads. Except for the head and related timing components, most parts were shared or interchangeable with the SOHC 18R. Combustion chambers were hemispheric. In 1975, air injection

It was a major departure for
585-474: The Crown's bodywork; Toyota now only used solid front axles on trucks intended to carry more than 1.5 tonnes (3,300 lb). The new version was available as a single-cab pickup (RS26) or as a two-door light van (RS26V), both fitted with the 1.5-liter R engine. In 1960 regulations were changed and passenger cars and light commercials were allowed to be longer and wider, with maximum engine size increased from 1,500 to 2,000 cc. Toyota responded accordingly with
624-474: The Dyna received a version tuned for torque, with a maximum power of 59 kW (79 hp; 80 PS) at 4600 rpm and torque of 145 N⋅m (107 lb⋅ft) at 3000 rpm. Applications: The 1.7 L (1,707 cc) 6R was produced from 1969 through 1974. Output is 107 hp (80 kW; 108 PS) at 5,300 rpm. The 6R-B was produced those same years, while the natural gas powered 6R-LPG
663-663: The Master were transferred to the Crown. In 1995, Toyota revisited the approach of a commercial grade Crown sedan, designed primarily for taxi usage, and introduced the Toyota Comfort which is still in production, with prolific usage across Asia. The Toyopet Master range also included the Masterline RR16 pickup, the Masterline RR17 van and the later Masterline RR19 double pickup (with two rows of seats). They were introduced in November 1955, originally only as
702-597: The Master. In 1957 the light van was lightly changed and was now fully glazed, rather than having pressed steel in the rear side windows. The first generation Masterlines were built until replaced by a new Crown-based generation in March 1959, for the Toyota Store sales channel. A total of 19,400 Master and Masterlines (excluding the Central Motors-built RR19s) were built by Kanto Auto Works until production ended in 1959. A smaller Coronaline version

About 12,000 RR16 and RR17 Masterlines were also built by Kanto, while the double cab RR19 was built by Central Motor Co. It is not known how many RR19s were built, but Central Motor Co. assembled a total of 43,241 double cab Masterlines and Crowns (from four generations) until December 1970.

936-574: The new RS30 Crown and RS36 Masterlines, which arrived in June 1960. This was also when Kanto Auto Works relinquished production of the Masterline. The pickup was called the RS36 while the light van received the RS36V chassis code. The bodies grew and two new bodystyles were introduced: a double-cab pickup (RS36P) and a four-door van (RS36V-B). The engine was upgraded to the 1.9-liter 3R version. Another difference

Induction was by a twin throat down-draft carburettor , the compression ratio was 8.0:1 and
1053-629: The total weight was 155 kg (342 lb). An LPG version, the R-LPG , was produced for the last two years. The R engine was the Toyota engine used in the 1958 Toyota Crown , the first model to be exported to the United States. Road & Track was unimpressed with the engine on its introduction, noting that it idled quietly but was "not capable of very high revolutions per minute." Applications: The 1.5 L (1,490 cc) 2R family

Output was 82 kW (110 hp; 111 PS) at 6,200 rpm and 136 N⋅m (100 lb⋅ft) at 5,000 rpm. It was a 2-valve DOHC design with two Solex carburettors and weighed 174 kg (384 lb).

Toyota managed to introduce yet another variant on the Master/Crown theme with the "Master Ribbon" which appeared in export catalogues in the first half of 1956. This was a series of light commercials using the body panels of the Masterline but with the more modern Crown chassis underneath, including that car's independent front suspension.

The double-cab could seat six people with a maximum cargo load of 500 kg (1,100 lb), but was subject to the lower tax applied to commercial vehicles, making it popular with construction firms and the like. The Masterline commercial models were carried over after the discontinuation of

As for the previous models, the Masterline was sold with Toyota Crown badges in export markets.

Production had been gradually transferred from the original Honsha plant to the new Toyota Kamigo plant in 1968. Applications: The 1.9 L (1,897 cc) 3R family was produced from 1959 through 1968. When introduced it had
