Valtra 8550 have different noise in engine and there is reason. We rebuild engine and change engine block and crankshaft. Engine is 7.4l. Sisu diesel 634DS.
Hello, I have been following your videos for many years and appreciate them very much. What do you recommend for an injection pump for a Valtra 8550? Can the lines and injectors stay old when changing it to the Bosch VE6\12? How many horsepower are possible with an original turbocharger?
Hei, olen fani, olen italialainen maatila, jossa on viisi Valtra-sarjaa 8000, 8050 2, 8550 2, 8950 1, T190 1 ..... voisitko auttaa minua antamaan enemmän suorituskykyä 8950hi: lle ...?
hi I have valtra 8550 hitech from 2003.when I go on the road hydraulic oil is very warm 90 or 95 degres.have you ever had a similar problem on your valtra please?
Yes I have similar problem 8050 valtra but reason is old hydraulic pump, its leaking inside pump and rising oil temperature when I driving road and use 2300-2400rpm. Next problem is probably oil cooling radiator is blocked. One problem can be too high rpm. if you hitech have over 90liter pump and you use over 2000rpm. Valtras problem is too small hydraulic valves and that easily rising oil temperature.
you can easily make it go 50 because its the low rpm model so it has the 50kmh gears but the revs are limited so it goes only 40 and that means you can just raise the limiter to make it go 50 but keep in mind that your hydraulic pump is different so it will break prematurely
Sata varmaa syytä ei ole mutta epäilys olisi että väärin ajoitetulla ruiskupumppulla vois olla osuutta tai lohko on ollut aina viallinen, Pullinki miehet on näitä särkenyt saman tyylisesti.
Eipä sitä taida olla specsattu 60km. vauhtiin. :/ ja eipä tuolla ajeta normaalisti kun reipas 40km. niin pysyy kulutuskin kohtuullisena mikä on itse tarkoituskin!
