LS Oil Pump Shimming- (correct method)

[@barrets6226]

Wow..... I would have just slapped it on and never thought about it needing adjustment. Thanks for the video, I'll be doing this job soon.

[@milojanis4901]

I did slap it on my first ls engine. Why? Because my 2000 factory shop manual made no mention of this!!! I'd bet money that the newer editions do. Remember, back in 2000, these engines and manuals were only in their 4th year of production, and new, better methods get discovered over time......

Does the fact that gears in a diff are set up with a certain clearance just like a LS pump, That tell you anything? Melling is doing the same thing in a less accurate manner lol, Melling just doesn't want idiots taking there pumps apart and *u*king them up and sending them back lol! So why does all the performance parts stores sell a Butler, Sac City, ICT or other LS oil pump alignment kit consisting of over priced feeler gauges? kzbin.info/www/bejne/equ4qmSImbSra5I

This is the same technique I used on my 2005 5.3 with a new Melling M295HV pump. I could only get 0.0015" feelers into it though --- but it got centered just like yours. Thanks for making me feel good about doing this pump.

[@mikerecords5530]

Much easier than other methods I've seen. Thanks.

[@champspec]

Awesome explanation. I’ve always done this. But i like your method better, by removing the shims. When you torque down the cover, there’s usually two of the bolt holes that have flattened edges, making them look slotted. I believe they are there to center the cover and should be the first two to install and snug down.

[@kyleallen3857]

Nicely explained I always wonder why people skip this simple step on, arguably, the most important engine component.

[@Mr572u]

Because many guys don’t know that it is necessary. KZbin is full of them.

[@SpeedDemon88X]

because the pump manufacturers (melling) void your warranty if you remove the front cover. Also if it was so crucial, GM service would have a procedure for centering the pump. They don't.

[@c41man]

@ Kyle Allen On my LS1 I installed a new Melling oil pump by priming the oil pump before I installed onto the crankshaft. Good oil pressure to this day.

[@milojanis4901]

I'd say that it IS the most important component!!! Without it, you could dump a $100,000 into your engine, and it wouldn't run for more than several seconds before it took itself back apart again!!

[@hardball107]

I installed the same pump on a build I did 2 years ago and just bolted it on. Melling told me there was sacrificial rings in the pump to center it, I didn't even torque the cover and after torqueing the mounting bolts there was no play which made me a little uneasy but no problems so far. I have used a similar method with GM pumps just centering the ring, I was glad to see that is how you did it. Thanks.

[@thetrueivaid]

Melling also told me it was not needed to shim the oil pump

[@davidcallahan5157]

Thanks for the explanation love the videos!

[@44hawk28]

All you need to increase soil pressure is 3245 mm bolt washers underneath that spring cap on the oil pump itself. You don't need to buy all these extra colored Springs. The spring that's in it works fine. Just shove the damn thing like we've been doing for decades. It's amazing how many people keep trying to reinvent the freaking wheel. It also doesn't help that there is at least 3 oil pressure relief valves on an LS motor. And one of them Works after the bypass valve that's in the oil filter.

[@postalaka]

[@onemoremisfit]

I have a pack of brass shim stock in various thicknesses, and I have an LS 5.3L truck engine apart, I think some strips of brass shim would work well for this operation. But even though my LS is very mildly cammed (stock idle and .05" more lift than stock) and has a SC system that makes 6psi max boost, I think I'm going to leave the bypass spring at stock oil pressure because I don't intend to race the truck and it will never see over 5000 rpm, and it will mostly tow, haul and highway cruise. More oil psi or volume when not really needed has a way of putting more oil in the valve cover area and causing oil consumption thru the PCV. My brother has a high HP, hi-rev supercharged intercooled LS that is giving this trouble. But one thing I did do was upgrade to a double row timing set designed to support 2000 hp (so I'm told). The stock timing chain was so loose after 100,000 miles it was a miracle it didn't jump a tooth, and this was 80% highway cruising and absolutely no racing. And replacing the timing set in the vehicle on an LS is not so easy as it was in the old days. Back in the day I changed worn timing sets on V8 Chevys, Buicks, Cadillacs, in the vehicle ... the cars all stalled due to the timing chain getting loose and jumping a tooth and you could tell by advancing the distributor and the engine would start again. Those days are over. You gotta put in a timing set that will last the life of the engine. LS truck engines are good for over 200,000 miles but the timing chains are good for maybe 100,000.

Hes been a dealer for over 20 years so it should be correct info !! And he also didnt warranty it so luckily i had the same 1 with the red and i swaped the guts out and got it fixed so if it brakes get a heat gun and get the black off of it before u hand it over for warranty!!

[@mikescaffo4850]

Well done sir

[@miarviwi]

Melling instructions are to install pump finger right. Then rotate the crank 360 degrees. Next torque pump to 18 ft/lbs and you're done. That centers that gear. Could they be wrong?

[@MLDIYSH]

Correct b/c this will automatically push out the gears to its proper spacing and youre done. The reasoning behind this is that once it’s ☝️ tighten, the 360 rotation of the crank will set the center spacing perfectly. New mechanic vs “old school”. If you bring this into a mechanics bay - they don’t have two feeler gauges handy - plus they don’t use them anyways unless it’s a rebuild shop etc.

[@RezurxnSpeedAndMarineHesperia]

Sorry to disappoint you guys but you can not always make it that simple. What Melling is telling you is that for a "stock" application you can get away with simply rotating the engine 360, and torque to spec. However, for kustom builds, generating generous power, "while changing out the stock spring to the COPO spring", just as this video is stating that this in fact is the application, you must shim the outer gear, utilizing .002 gauge then torque to spec. If you dont, the pump will fail. I have the destroyed pump and timing cover to prove it. You will only make that mistake once! I have a good deal of engine building experience and by far this is the most comprehensive video I have come across.
