I have a pie wagon last year I put a couple bench seats in the back and take neighbors for rides everyone always complains about exhaust smell so I took it to a fabricator who welded the muffler around the front and back covers and he made a tail pipe all the way to the back, cured that problem but now it seems that the pipe before the muffler is getting real hot, could the tail pipe give it too much back pressure?
Up to about 1917 the muffler had a tail pipe. Could be that now that you are aware and have made changes you are noticing it getting warm, probably was doing the same before.
The tail pipe to muffler is a slip fit for expansion, no clamps should be used. If the pipe is welded or clamped (?) to the muffler you will need to have a different mount to frame for expansion and contraction.
Hi! Guys,I just found out that I can't install my
hogshead because it is touching the back of the engine and won't go down because of the 5th bearing
flange,is this normal or must I pull the rear end back.I never did this before,I put new bands in my truck when I bought it but it had removable ears which I thought was normal so I never had a HH off.
Mark, it is getting extra hot today the floorboard caught fire, never happened before the engine was not overheating just the pipe
Than you may be running too lean and not enough spark advance.
What size is your new tail pipe?
You need to loosen or remove the bottom two bolts on the 5th main / ball cap to give the hogshead room to drop into place.
Tail pipe is same size as pipe ahead of muffler
Could also be an obstruction in the muffler....
Something definitely wrong if the floorboard catches fire.
Run your tail pipe all the way to the back and install the muffler at the end.
The flash fire point of wood lowers each time it is heated. If the floor boards are old and heated many times before the flash point might be low.
That's why wood stoves and chimneys have installation clearance specs they may not catch fire until the flash point lowers with some times years of use.
Wood stoves some times are installed with a none combustible shield spaced a few inches from a combustible wall with air flowing between the two.
You see shields doing the same thing on modern car exhaust systems in hot areas.
