I just restored a 1810 and converted it to a 1811 (added hydraulic lift).
After driving it for the first time after the project was done, it drove perfect for about 10 minuets or so, then it started to "lurch" forward when starting from a dead stop and the same for reverse, instead of "easing" into forward movement or easing into reverse movement.
Could this be from adding hydraulic lift and not bleeding air out of the system? because I did not !...I do have one hydro relief valve leaking, but I don't think that could be causing this problem, or am I wrong ?
Any and all input will be greatly appreciated
PS...I also changed the hydro fluid and filter.
