What is the difference in the D6C 10K 1- 7952 and 10K 7953 +. I have D6c 10k6574 and wondered what the big change was? I noticed my parts manual stops at 7952.
D6c D6C 10K7953 up uses the 3306 engine with a 3N serial no. Earlier units used the D333C engine. Same basic engine, different front cover and water pump and oil filter are main differences. Later engines used the sleeve metering fuel pump instead of the scroll type pump. Hp remained the same at 140. Merv :drinkup
That was when the engine change from D333c to 3306 happened I think.
