Get a 770 serviced in Kent?

Post by Kent770 » Wed Apr 05, 2017 9:33 pm

I have a 1965 770 that has was used for 30 years for scraping out cattle sheds and has probably not been serviced in at least 20 years. It still runs and although the battery discharges it starts first time on jump leads and the hydraulics also work. It is blowing smoke out of the oil filler which I've read somewhere might indicate a cracked engine block? Although I've got the original handbook which gives pretty detailed instructions on maintenance, I don't have the facilities or equipment to service it myself (or probably the expertise). I'd like to have it completely restored at some point (it has sentimental value) but can anyone recommend someone in Kent or nearby that could a) carry out a service (change oil, filters etc) / diagnose the smoke issue and b) undertake a complete restoration?

when you say 'oil filter' do you mean the breather pipe on top of the rocker box?

Blowing out smoke from the oil filler is most likely a result of piston blow by. A cracker engine block will not give these symptoms. The cylinder walls will get glazed if a diesel engine is used for longer times with low power output and low revs. Try to give the engine some heavy work and see what will happen.

Joe - the smoke is blowing out of the 'engine oil filler' as it is described in the handbook (located below the sediment bowl).

Ollek - thanks for the thoughts on the piston blow by - makes sense. I suspect really the engine needs to be opened up to see what condition the pistons and cylinders are in.

Before you start delving in she needs fresh oil and filters all round and some heavy and prolonged pto work if you can find any.....failing that ....a heavy trailer and a long might be surprised how she responds.........often they glaze .....many restored tractors by the road run brigade end up like this through tickling about.....👍
