Sample Gostekhnadzor Category E Theory Exam Practice Questions

Try these sample questions to review concepts for the Gostekhnadzor Category E Theory Exam exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 93+ question experience with AI tutoring.

1In the official Category E ticket set (based on the Gostekhnadzor technical-inspection fault list), above which range of track-chain sag is operation of a crawler machine prohibited?
A.10–20 mm
B.35–65 mm, depending on the machine model
C.90–120 mm
D.There is no sag limit; only a broken track bans operation
Explanation: The official Minselkhoz tickets for Category E ask at what excess of track sag operation is prohibited, and the answer is the 35–65 mm range, depending on the machine model, citing the Gostekhnadzor technical-inspection fault list. A track sagging beyond this can be thrown off the idler or sprocket and damage the track frame.
2What primary operational hazard and mechanical failure occurs if a crawler track chain is overtightened?
A.Better track grip in soft soil with no mechanical drawback
B.Less wear on the drive sprocket because the chain cannot slip
C.Lower fuel consumption because the track no longer sags
D.Faster pin and bushing wear, hot bearings and lost power
Explanation: An overtightened track chain drastically increases rolling resistance, consuming significant engine power simply to turn the undercarriage. Furthermore, extreme tensile loads accelerate abrasive wear on pins, bushings, and sprockets, while placing damaging radial loads on final drive and idler bearings.
3What is the primary danger of operating a crawler tractor with an excessively loose track chain?
A.It can come off the idler or sprocket and skip teeth under load
B.The track becomes stiffer and overloads the idler bearings
C.The machine gains grip on slopes, so slack is a safety advantage
D.Only the noise level rises; there is no safety effect
Explanation: A loose track chain lacks lateral stability and guidance on the idler and track rollers. Under turning loads, side slopes, or reverse maneuvers, the track links easily climb the idler guide flanges, causing track shedding (сбег гусеницы), tooth skipping, and potential destruction of track frame components.
4How is track tension adjusted on crawler tractors equipped with a hydraulic track adjuster cylinder (гидронатяжитель)?
A.By adding high-viscosity gear oil directly into the front idler hub cavity
B.By pumping grease into the adjuster cylinder through a grease fitting
C.By bleeding hydraulic fluid from the main implement distributor valve until the track tightens
D.By loosening the recoil spring retaining tie-rod bolts until the idler slides forward
Explanation: Hydraulic track adjusters use a cylinder filled with grease. Pumping grease through the fitting with a lever grease gun pushes the piston and the front idler forward, taking up slack; to slacken the track, the relief valve is opened carefully so excess grease escapes.
5What is the correct procedure for tensioning tracks on crawler tractors fitted with a mechanical screw tensioner (винтовой натяжитель)?
A.Tighten the screw with the engine running and a gear engaged so the track is under load
B.Remove a track link instead whenever sag appears, without touching the adjuster
C.Loosen the locknut, set the sag with the screw, then retighten the locknut
D.Adjust only the left track; the right track follows automatically through the final drives
Explanation: Mechanical track adjusters rely on a threaded adjusting screw and locknut mechanism. The operator must clean the exposed threads, loosen the locknut, rotate the screw/adjusting nut to advance the front idler until track sag matches manufacturer specifications, and then securely tighten the locknut to prevent spontaneous backing off.
6According to the official Category E tickets, below what residual grouser (почвозацеп) height of a metal track chain is operation of a DT-75-type crawler tractor prohibited?
A.Below 3 mm
B.Below 7 mm
C.Below 10 mm
D.Only when the grousers are worn completely flat
Explanation: The official Category E tickets, citing the Gostekhnadzor technical-inspection fault list, state that operating a DT-75-type machine is prohibited when the residual grouser height of the metal track is less than 7 mm. Worn grousers reduce traction and make the machine likely to slide on slopes and wet ground.
7How must the pins of crawler track links be secured, according to the official Category E tickets?
A.With twisted soft wire, which is easier to inspect
B.With home-made cotter pins cut from any available steel
C.With factory cotter pins or ones made to that pattern
D.No securing is needed if the pins are a tight press fit
Explanation: The official Category E tickets require track pins to be secured with factory cotter pins or pins made to the factory pattern; wire, home-made or improvised fixings are not allowed. An unsecured pin can work out and split the track.
8What critical safety step must be performed before splitting a crawler track chain for repair or replacement?
A.Release the track tension and chock the track securely
B.Split the track at full tension so the chain stays aligned on the rollers
C.Keep the engine running so the track can be moved quickly once the pin is out
D.Raise the machine on the blade and leave it held only by hydraulic pressure while knocking out the pin
Explanation: A tensioned track stores immense elastic energy in its recoil spring. Prior to driving out the master pin, the operator must completely relieve track adjuster pressure by opening the grease release valve or loosening the mechanical screw, and block the track shoes with chocks to prevent violent uncontrolled chain movement.
9Why must the operator thoroughly clean dirt, mud, and frozen slush from track links and rollers before parking in winter?
A.To keep the tracks clean enough for travel on public roads
B.To protect the paint on the track shoes from corrosion
C.So frozen mud cannot lock the rollers and break links
D.To reduce noise from the carrier rollers the next morning
Explanation: In sub-zero conditions, wet mud and soil packed inside the undercarriage freezes into a rock-hard mass, locking the track rollers, carrier rollers, and idlers. Forcing the tractor to move with frozen undercarriage components will flat-spot rollers, shear drive sprocket teeth, snap track pins, or burn out steering clutches.
10What is the key operating characteristic and restriction of swamp-dozer crawler tracks (болотоходные гусеницы) with extra-wide shoes?
A.They spread the load enough to allow driving on asphalt roads
B.They allow working across slopes steeper than standard tracks permit
C.They allow amphibious travel across open lakes and deep rivers without a hull
D.Low ground pressure on soft marsh, but faster wear on rock
Explanation: Swamp versions of crawler machines (for example the B10MB or DT-75B) have extra-wide shoes that lower ground pressure for work on bogs. On hard, rocky ground the overhanging shoe edges take high bending loads, so shoes warp, links crack and pins wear quickly.

About the Gostekhnadzor Category E Theory Exam Exam

Category E covers tracked machines with an engine power over 25.7 kW (Federal Law No. 297-FZ, Art. 15), such as crawler tractors and bulldozers.

Gostekhnadzor Category E Theory Exam: Suggested Study Strategy

1Learn the official undercarriage limits: track sag 35–65 mm, equal link counts left and right, and track pins secured with factory-pattern cotter pins.
2Know the hydraulic rules: never stand under a blade held only by hydraulics, lower equipment before leaving, and relieve pressure before uncoupling.
3Memorise slope rules: select a low gear before the slope, never disengage the clutch on it, keep the blade low on descents and stay outside the collapse prism near trenches.
4Review starting rules: never wrap a starting cord around the hand, never start by shorting the starter or from the ground, and refuel the starting engine only with the main engine stopped.
5Revise refuelling and fire rules: refuel with the engine stopped, use a torch rather than a flame for light, and never add petrol to diesel.

Frequently Asked Questions

What track condition prohibits operating a crawler machine?

The official Category E tickets prohibit operation when track sag is outside the permitted 35–65 mm range, when track links are cracked or broken, or when the left and right tracks have different numbers of links.

How is the Category E theory examination run and scored?

The theory examination uses the Ministry of Agriculture-approved tickets for the category (the ticket books use 8-question tickets) and is taken orally or on an examination terminal at the regional Gostekhnadzor body; remote participation is available on request. Under Decree No. 796, para 22(2), the result is a pass if at least 75% of the ticket questions are answered correctly within the allotted time — at least 6 of 8. No fixed national time limit is set in the Decree.

Who may sit the Category E examinations?

Under Decree No. 796, para 11, candidates must be at least 17 years, hold a valid medical conclusion on fitness to drive self-propelled machines, and have completed vocational training at an organisation holding a certificate of compliance for training tractor and machine drivers.

What happens after a failed attempt?

A candidate who fails the theory examination is not admitted to the practical examination and may retake the theory no earlier than 7 days later (Decree No. 796, para 19). Theory results remain valid for 3 months (para 20). A failed practical examination may be retaken no earlier than 7 days later; after three consecutive practical failures, the candidate must first complete repeat practical training (para 21).

What does the licence cost?

No fee is charged for sitting the examinations; issuing the tractor-driver licence (УТМ) carries a state duty of 500 RUB (paper) or 2,000 RUB (plastic) under Tax Code Art. 333.33(1)(43). The tractor-driver licence is issued for 10 years (Decree No. 796, para 34).
