Manual transmission repair <em>Nissan Almera Classic B10</em>: complete guide with photos and tips

Nissan Almera Classic B10 is a reliable car, but even its manual transmission requires attention over time. A grinding noise when shifting, difficulty switching gears, or an oil leak are all signals that repairs are needed. In this article we will analyze typical malfunctions of the Almera Classic B10 manual transmission, methods for diagnosing them and step-by-step repairs taking into account the features of this model.

Gearbox on Almera Classic (code B10) is equipped with a 5-speed manual transmission type RS5F32A or RS5F31A (depending on the year of manufacture). Structurally, it is simple, but has weak points: wear of the 2nd and 3rd gear synchronizers, leakage of oil seals and input shaft bearings. If you ignore the first symptoms, repairs can cost many times more, including replacing the entire box.

We will not convince you to go to the service center - instead, we will show you what kind of work can you do yourself?, and when you can’t do without the help of professionals. At the end of the article you will find a FAQ with answers to frequently asked questions and a table of spare parts costs.

Signs of manual transmission malfunction Nissan Almera Classic B10

The first “bells” about problems with the gearbox are often attributed to “car features”. However, ignoring symptoms leads to critical wear of gears and bearings, after which repairs cost 30–50 thousand rubles. Look out for the following signs:

• 🔊 Crunching or grinding noise when changing gears (especially 2nd and 3rd) - a signal about wear of the synchronizers.
• 💧 Oil stains under the car in the area of the manual transmission housing - the input shaft oil seal or gasket is leaking.
• 🔄 Difficulty turning on 1st or reverse gear - a problem with the forks or synchronizer clutches.
• 🌀 Vibration or noise in neutral gear - wear of bearings or gears.
• 🛑 Spontaneous shutdown transmission while driving - critical wear of gears or synchronizers.

If you notice any of these symptoms, the first thing to do is check the oil level in the manual transmission. On Almera Classic B10 this is done through the control hole on the box housing. The oil should be level with the bottom edge of the hole. If there is not enough of it or it is black with metal shavings, get ready for repairs.

⚠️ Attention: Never add oil to a manual transmission through the breather! This will lead to excess pressure and leakage through the seals. Use only the inspection hole.

Manual transmission diagnostics: what you can check yourself

Before disassembling the box, perform simple diagnostics. This will help narrow down possible problems and save time.

1. Oil check:
   • 🔧 Unscrew the control plug on the manual transmission housing (the key is on 24).
   • 📏 The oil level should be at the bottom edge of the hole. If it's not there, add more GL-4 75W-90.
   • 🔍 Oil color: light brown - normal, black with glitter - needs to be replaced.
2. Checking the backlash:
   • 🚗 Put the car on the handbrake, turn on neutral.
   • 🔄 Swing the manual transmission lever to the sides. Backlash more 1–2 cm - a sign of wear on the bushings or forks.
3. Noise test:
   • 🔊 Start the engine, squeeze the clutch. The noise has disappeared - the problem is in the release bearing.
   • 🔊 The noise remains - wear of the bearings of the primary or secondary shaft.

If after checking the oil and play the problem does not disappear, you will have to remove the box. On Almera Classic B10 this can be done without a hole, but you will need a jack and reliable supports.

Step-by-step manual transmission repair Nissan Almera Classic B10

Disassembling and repairing a manual transmission requires patience and accuracy. Below are step-by-step instructions taking into account the features of the box. RS5F32A/RS5F31A.

1. Removing the gearbox

To dismantle the manual transmission you will need:

• 🔧 Set of sockets and keys (10–19 mm).
• 🔨 Crowbar and hammer.
• 🔗 Puller for CV joints (optional).
• 📦 Oil container (volume ~2.5 l).

Sequence of actions:

1. Drain the manual transmission oil through the drain plug.
2. Disconnect the clutch and shift cables.
3. Remove the starter and disconnect the speed sensor.
4. Unscrew the bolts securing the box to the engine (total 8 bolts).
5. Carefully slide the box back, removing it from the input shaft.

⚠️ Attention: Do not drop the box when removing - this may damage the bearings or gears. Use a helper or a winch.

2. Disassembly and replacement of worn parts

After removing the box, disassemble it in the following order:

Typical faults and their elimination:

Malfunction	Reason	Solution	Cost of spare parts (RUB)
Crunching sound when shifting 2nd gear	Synchronizer wear	Replacing the synchronizer and clutch	1 200–1 800
Oil leak from under the crankcase	Worn gasket or oil seal	Replacement of gasket + sealant	300–800
Vibration in neutral	Primary shaft bearing wear	Bearing replacement	2 500–3 500
Difficulty engaging reverse gear	Fork or gear wear	Fork replacement + adjustment	900–1 500

When disassembling, pay attention to the condition gears and synchronizers. If there are burrs or chips on their surface, the parts must be replaced. Also check seals and gaskets: Even a small leak will eventually lead to oil starvation and accelerated wear.

How to check manual transmission bearings without special tools?

Rotate the shaft by hand: if you hear a crunch or feel play, the bearing is worn out. Also inspect it for rust or wear.

Selection of spare parts: original vs analogues

When repairing a manual transmission Nissan Almera Classic B10 You can use both original spare parts and high-quality analogues. The main thing is to avoid cheap fakes that fail after 10–20 thousand km.

Recommended manufacturers:

• 🔧 Original (Nissan) - reliable, but expensive. Articles:
  • 2nd gear synchronizer - 32026-31X00.
  • Input shaft bearing - 32010-31X02.
  • Manual transmission oil seal - 32026-31X00.
• 🔧 Analogues (quality):
  • Koyo or NSK - bearings.
  • Febi or SWAG — synchronizers.
  • Corteco - seals and gaskets.

The cost of original spare parts in 1.5–2 times higher than analogues, but their resource is longer. If your budget is limited, choose trusted manufacturers (see table above). Avoid Brands NoName - they are often counterfeited.

Assembly and running-in of manual transmission after repair

Reassembling the box should be done in reverse order. Pay special attention to:

• 🔧 Bolt tightening torques (see table below).
• 🛢️ Refilling oil - use only GL-4 75W-90 (volume 2.3–2.5 l).
• 🔄 Adjusting the clutch cable — incorrect setting will lead to difficult switching.

Key bolt tightening torques:

Detail	Tightening torque (Nm)
Bolts securing the manual transmission to the engine	45–55
Manual transmission cover	18–22
Drain plug	30–35
Main shaft bearing	80–90 (requires torque wrench)

After assembly, run running-in:

1. Fill with new oil and check its level.
2. Drive 200–300 km no sudden acceleration or shifting.
3. Check the box for leaks and extraneous noise.

⚠️ Attention: If the gears are difficult to engage after repair, check the clutch cable adjustment. On Almera Classic B10 it is adjusted by a nut on the pedal bracket.

Repair cost: do it yourself vs service

The price of manual transmission repair depends on the complexity of the work and the spare parts used. Below are indicative prices for Nissan Almera Classic B10 (for 2026):

Type of work	On your own (RUB)	In service (RUB)
