BL-275 Update: it was all bad. As stated by others the main pump is too small, mine spun in the case. Swash plate was bad drive motor, pressure relief valve was shot. A friend who is more than a mechanic built me a new drive system pump is twice the size of the original and made from a th700 planetary gear, swash plate and it’s case is custom made as well as the main relief valve. He spent 5 months machining new parts but now it does a wheelie all functions work well and I have higher flow at the auxiliary.
