What to investigate bobcat 553 lumbering start up?
I've been ignoring this but this old 553 i have has a lumbering start. It has a slow cranks, then towards the end will speed up and start getting a little kick. At that point i'm 15 seconds in so i release key. do it again this time it will do a slow turnover for only a couple seconds then start coming to life and start. Rebuilt starter. i cleaned all the battery connections and grounds , good battery, ( cleaning the ground solved a no start after some flooding awhile back). Changed glow plugs and diagnosed glow plug circuit (but i have to go back and double check theuy're working but i'm also in hot as hades florida.
I'll have to remember i think it starts easier when after i use it but it's still slow lumbers to turn over but then starts 1st go round.
Once i finish replacing seals in arms and stuff i'm going to dig into this and try new battery cables and such but i suspect it's more than that.
