Cab construction
Once the main chassis compenents have been fitted we move onto the cab construction and is often the case with
trucks and cars we are faced with the dilemma of how to approach painting the
interior. Unfortunately, Zvezda have not
helped us with this task! They have
designed the cab roof to join just behind the screen where there is not
actually a joint on the real vehicle (so far as I could determine) Masking the joint after painting the interior
would not be my preferred plan of attack so I figured that issue would need to
be addressed first.
I have built the Zvezda L4500 S with the wooden cab so a
fair amount of parts on this kit are identical.
You got both the metal and wooden cab with that kit and as I had built this
cab previously, I employed the same method of construction with this kit.
To be able to get decent access to the cab interior with the
airbrush and add the instrument decals the cab needs to be built in two
halves. The windows on mine will be left
off until the cab is painted. I started by building up the rear section,
cementing the floor and cab rear together. I left off both the seat and seat
back until both parts had cured to avoid any potential interference. There are
a couple of tabs on the inside of the rear panel to line up to the floor and it
is important to make sure the lower points of the rear panel sit at the same
height as the bottom of the floor moulding. I found out in my earlier build this
positioning is critical for getting the best overall alignment of the cab, and more so
if building with the doors shown closed.
Once dry the front panel and roof can then be attached to one
another. Whilst curing I dry fitted them to the rear section already built up
with masking tape to ensure the roof dried at the right angle. Once fully cured the any joint line can be
easily cleaned up and masked. Once dry
the dash panel can be fitted.
The main issue with the whole cab assembly, I found, is with
the doors. They do require some trimming to sit well in the closed position and
any paint added will make this even worse such are the fine tolerances of the
fit. The sprue gate position on the door
parts is awkward to clean up as they are positioned right over the intersection
of outer skin and inner body. If you wish to model the kit with the cab doors closed
a great deal of trimming and test fitting will be required to get a good
overall fit. I dry fitted my front and
rear cab assemblies together with the doors with masking tape. Much test fitting was made before I was happy to proceed
In step 22 you are to attach the steering box and column to
the chassis at the same time as you add the completed cab assembly. This is fine if you follow the instructions
as the steering wheel can easily be fitted to the column inside the cab as the
roof top part is still unattached. This also allows you to complete the
steering link assembly in step 22
As I had adopted a different approach my solution was to cut
the column off just above the steering box, drill both pieces and insert a
piece of copper wire. This way I could attach the steering box to the chassis,
complete the steering link assembly and still be able to line the column up
once the cab was painted and completed. Using my method of cab construction the
steering wheel will still need to be cemented to the column inside the cab
after it has been pushed through the bulkhead as the roof I had connected to
the front panel will obstruct the fitment if connected together. To aid
painting the steering wheel in its final resting place I dry fitted the cab to
the chassis and with the aid of the copper wire attachment to the steering box,
was able to determine the wheel location in the cab. I then added a spot of
Blu-Tak to the column as it passed through the bulkhead to hold it in place for
painting.
As already mentioned the engine assembly will not locate in
the engine bay once the cab is fitted so the chassis so if you wish to paint
the engine separately you will also have to leave the cab assembly off.
Radiator, engine panels & fenders
In my last L4500 s build I displayed the vehicle with the
bonnet/hood completely removed but this time I planned on only removing the top
half of the driver’s side panel. This
meant that the radiator housing, bonnet/hood and bulkhead all needed to line
up neatly. Making this an altogether more
difficult task was that both fenders also locate to points on both the chassis, cab
floor and engine side panels.
The instructions have you adding the fenders to both the
chassis and cab floor after the cab is fitted to the chassis. In leaving the cab assembly unattached for
painting this meant I would now attach the bonnet/hood, engine side panels and
the radiator housing together to ensure a good fit.
Attaching the strengthening bar to the underside of the
bonnet/hood first, I then cemented it to the cab front assembly (bulkhead). Once dry I added both engine side panels and
finally the radiator housing making sure that all parts sat at the correct
angles. Once this now bigger sub assembly was dry I test fitted the engine for
any clearance issues. All appears to fit well.
As for how the engine sits in the bay pay particular
attention as to how the rear of the engine locates onto the chassis. There are two location slots, but they will
require widening to get the engine to sit flush on the crossbeam. This is a particularly important step as if
the engine sits too high it will interfere with the cab assembly.
With the engine snugly located in the engine
bay the front cab assembly was test fitted to the chassis. As with the previous L4500S build the tab at
the rear of the block needed trimming and also the top of the gearbox needed
shaving a little to get the cab to fit on its two forward location
brackets. Happy that all looked to fit
well and that the steering column located into the steering box I could now position
the front fenders to the chassis. The cut out for the steering box outer arm on
the driver’s side fender needed widening on my kit but once addressed the underside
cut out makes positioning them easy.
