Addy, Edward, Swoop223- Wish you all a very happy new year and extremely sorry for my delayed response as I was out of the country. Just returned. I went through your replies from overseas but could not respond as I did not have my password with me to post a replies. Sorry about it.
During my trip I purchased an infrared industrial thermometer and intend checking the temperature tomorrow morning and inform you'll the same. What is maximum acceptable temperature of the hydraulics of a forklift when it has run for a considerable period ? than Its very strange that this truck has only 01 hydraulic filter which is the in line filter and there is NO return filter. When enquired from UN they response was- this model has only 1 hydraulic filter. We changed the seals of the pump too but the problem remains the same. UN has finally sent us a warranty pump and a motor, which we intend installing tomorrow. Shall keep you posted on the outcome
