drott td 150

sdd · Apr 24, 2015

Hi, new here and looking for info on a crawler my dad has. Believe it to be a early 60s model IH 150 with drott attachment. We were having a leak of hydraulic from back left (as setting on machine). There is a large spring over a cylinder with just one line going to it. Can someone tell me what this is? The spring itself has broken in 5 pieces, and fluid is flowing out of the seal on bottom of spring assembly. Parts available?
Thanks.

That spring was known as a Hydro spring,it is a shock absorber,say if the bucket was full and raised and you dropped it down that spring would absorb the shock,the oil is forced into the cylinder and in turn the cylinder is forced against the spring deadening the shock,there is usually an on/off valve to turn that function off for grading and the like,if yours does not have an on/off valve remove the hose and blank it off to keep going till you source out parts.
