I've got a onan b43e i'm trying to disassemble completely to get new gaskets in it and inspect it, but cant get the crank gear off. there is a key in it and cant figure out how to get that out so i can get the gear off. any ideas would be great. thanks.
The best way to get that gear off is heat from a good torch. Heat just the gear (not the shaft) and it will expand, while leaving the crankshaft at the same size. Try to use as much heat as possible to quickly get the whole gear heated up. Then use the puller on it. It will be much easier that way.
Hello everyone! Keeping in mind that I am somewhat electrically inept, can someone tell me how to test the output of the alternator on my 98 455. It had been cranking slow and I had to jump start it during the cold snap we have here in Michigan. Once I got it started I was plowing with the headlights on and it just quit. I was able to jump start it again and got it inside. I put a voltmeter on the battery which is a few years old and got nothing. I will be installing a new battery but I want to make sure that the charging system is working. Any advice in simple terms will be greatly appreciated. Thank you in advance!!
Measure battery voltage without the engine running.
Now start the engine and measure voltage, quickly after starting.
there should be an increase in system voltage as the battery lost some charge with the start and the alternator/regulator should be in replenish mode. Normally, engine running system voltage should be around 13.2-6.
If you don't see that, more in depth tests are in order.
