    Still waiting on the copper head gaskets so i setup some closed chamber heads for the bandolero HO in another puller that's in the shop.


    I'm looking a get 225lbs compression so decided to o ring them

    milled .005 to clean up


    used a 18/20hp gasket to scribe the cyl location





    cut the groove and tap the wire in with a piece of hard nylon, need to make sure the ends of the wire is square so there's no leak. .045 wire so the groove is .43ish wide and .040 deep. need to remember to add the .005 the wire sticks out to your total number for piston to head clearance including gasket thickness and deck height. total of .027 to .032 is the magic numbers. had to sneak the groove up a bit to clear the alignment pins

    Nubs: If you don't mind can you tell me what Header kit you used on the engine in the pic ?
    Thinking of using an off the shelf rather than Fab one up at the shop ?
    Thanks

    Old school Bandolero setup done, 14hp closed chambered heads, 23hp valves and the Briggs aluminum rockers.
    the 23hp intakes are .080 larger and the exhaust are .055 larger than the 14/20's, installed head studs to save on thread stress from head changes and added compression.
    valve springs and retainers from EC distributing, good for 12K rpms

    know his has nothing to with this thread but it was the last thing i had to do to wrap up this one. hoping to get the head gaskets soon... and back to the other one


    These engines in the pullers run flywheels, seems that most run a 17lb wheel




    This fella wanted one as heavy as he could get, carved one out of some 8", weighed 48lb after balancing

    I understand why he wanted it, but... Can the crankshaft, bearings and seal handle it for long? Have you put babbitted bearings in them?


    My new beer holder spilled some on the trails - in it's hair and down it's throat.
    Joe Camel never does that.

    Well I think its crazy myself but it seems to work, made this one 4yrs ago and the guy is still runnin' it. they only run about 45 secs under full rpm/load, this tractor turns 8K and seems smooth
    There is a lot of side load on engine's in some equipment and none here so i don't know. it has a 360 degree guard and runs with full tins, if it does snap off its not gonna be good that's for sure...

    Got the head gaskets today, the chambers on the 23hp heads are about .095 wider than the .020 over 18hp bore.





    scribed the chamber foot print on the gasket and ground it to match, then transferred that to the block and blended the top of the cylinder to match. guys did this years a
    go on big block GM's etc for valve clearance. Sorry for crappy pictures
