    Cool 4016/16 Vanguard coming in for re-power with new 18 Vanguard

    Hi Troops,
    I have a friends 1996 4016 with a problematic 16 Vanguard coming in soon for a re-power with a new 18 Vanguard. I had this tractor here for servicing last spring and the engine had serious blow by and leaking crankshaft seals. At that time I recommended a re-power and the owner has finally agreed. As Briggs has changed the flywheel design on new production Vanguards, some changes will need to be made. There are several folks here that have already done this re-power, I haven't as yet. Unfortunately, there have been more that the average problems with horizontal shaft 16 Vanguards particularly with 1996 and older production engines. Although they are rebuildable, the time and cost of parts and boring the cylinders if needed comes close to the cost of a new engine.
    When I do this, I will take pics and post here.

    Fedex delivered a nice fresh new 18 Vanguard today from Small Engine Warehouse. This engine was built June 17th of 2020, they don't get much newer than this! Next week I will pick up the 4016 that this engine will go into as the owner wants to clean up his lawn over the weekend weather providing. The new engine is a 356447-0080 which is a basic local start, throttle and choke engine. The local throttle lever and cable, choke lever, keyswitch and electrical harness will be removed. The throttle linkage on the engine is setup for L/H or R/H side remote throttle cable connection, the choke is the usual L/H side remote cable setup. Extra parts were in the package for a full throttle situation as in a generator or similar. As Briggs has changed the flywheel on newer production engines, SEW tells me that I need to use the old engine flywheel, starter motor and blower housing, I will see when I have the old engine out of the tractor and compare parts. Pics will be posted soon!

    Hi Bob,

    I had my friend swap out my Vanguard 16HP this summer. It was getting tired and started blowing oil near the carb, vent hole. I agree my tractor had 745 hours on it and I felt for $1320 it made sense to replace it. So I gave Vanguard a call and within seconds the nice man gave me the exact replacement engine and I bought through a local tractor dealer. I had the engine 2 days later, ordered it on Wednesday and picked it up on Friday. My friend who does small engine repair was in his glory, the only issue he had was with disconnecting the hydradrive. But he figured it out. Now if I can just get the PTO clutch installed, burnished, and running I'll be happy.

    I'm curious what made him decide to go with a 18hp rather the 16hp?

    Dave

    Going with an 18 Vanguard was my decision, a little more HP is a good thing. I will need to use the flywheel, blower housing and starter motor from the 16 Vanguard due to changes in the flywheel, blower housing and starter motor on new Vanguards in order to connect the pump drive adapter. The muffler from the 16 will also be installed onto the 18.
    The owner of the 4016 hasn't brought it to me yet but I do have the new 18 Vanguard here.

    Hi Troops,
    Yesterday I picked up the 4016, brought it into my shop and removed the engine. I took some pics of the removal process and when I annotate them I will post them later today. I removed the flywheel and the clutch and you will see in the pics what I discovered!
    I am heading out to do a job that will be an all day one!
    Later

    Pics of the new 18 Vanguard. As the new Vanguards have a different flywheel, starter motor, cooling fan and blower housing, these items will be removed and replaced with the same parts from the 1996 vintage 16 Vanguard.

    Do you have any pictures of the pump with the engine out?

    Thanks, was curious about how the torque arm fitted. Looks like it could be a Parker pump, and special at that; side port for suction and end port for pressure.

    Hi Troops,
    Partially cleaned the tractor today. As the 16 Vanguard had some serious oil leaks, I had to scrape the crud off the blower housing and the flywheel and followed up with brushing in parts cleaning solvent. These parts and the starter motor had to be installed onto the new 18 Vanguard due to flywheel, fan and blower housing changes on newer production engines. I installed the oil drain fitting onto the new engine, filled it with oil, removed the spark plugs and cranked it over with a cordless drill with a socket on the flywheel nut to prime the lube system. I need to clean the oil off the clutch. I will disassemble it, clean it, check the coil resistance, reassemble it and set the air gap. With a spare pump coupling bolted on the flywheel to keep it from turning, I will reinstall the clutch if it is OK and torque the bolt.
    I noticed that the spark plugs were Champion XC92YC, this is a new plug to me as I'm familiar with Champion RC12YC plugs for use in most Briggs engines. I will post some pics of both engines tomorrow. Both crankshaft seals on the old engine were loose and the air filter was oil soaked, not sure why this engine actually started and ran fairly well!
