Valtra Turbocharger

Which Valtra tractor models are represented?

The current catalogue includes Valtra BF75, BL77, BL88, and 700 tractor applications associated with 302 or 320DS engine notes.
The turbocharger is identified in the S1B family by numbers 315921 / 315920, with OE reference 836659179.
Model and engine serial information should still be checked because agricultural machines often remain in service through several rebuild cycles.

How should 836659179 be verified?

Provide the tractor model, serial number, engine plate, full turbo tag, and photos showing compressor outlet, turbine flange, oil ports, and wastegate.
State whether 315921 or 315920 appears on the original unit or in a replacement list.
We compare the reference family with the installed geometry before confirming the complete turbocharger.

What if the Valtra tractor has a replacement engine?

Identify the current engine and photograph the manifolds and pipe routing.
The tractor's original model-year data may no longer describe the installed turbo if an engine swap or local conversion was completed.
Measurements of the flanges and outlet diameters can support the physical review when documentation is incomplete.

Can agricultural wholesalers include Valtra in a mixed order?

Yes. Elecdurauto can coordinate confirmed Valtra demand with Massey Ferguson, New Holland, John Deere, Case IH, and other agricultural turbochargers.
Our screened supplier network makes wider model coverage possible and can offer options suited to different price-quality targets.
Each tractor line remains linked to its engine and OE evidence.

Which farm conditions should be corrected before replacement?

Check dust entry through the air filter or hoses, oil-feed cleanliness, drain restriction, exhaust leakage, and excessive fueling or temperature.
Clean the intake system after compressor damage and replace contaminated oil and filters as required.
Prime the S1B turbocharger and follow the engine service instructions before returning the tractor to load.
