Briggs engine 44q977. How do the valve seals come out and how are new ones installed?

Makes sense. But what if you took equal number of “strokes” on sandpaper on both halves of the rod?

Mine did not have instructions. It’s from harbor freight but don’t yell at me……

How can I insure I am reading it right and it is accurate?

Why did I come up with .9996??

Standard- 0 to 1 inch

Trying to teach myself to read and calibrate a micrometer. Can anyone tell me this reading?

What do you mean pinch the journal?

I have no clue who to contact at Briggs. I have heard a rule of thumb is .001 times the crank normal diameter but have no clue if that is right.

No it’s to my John Deere zero turn

The client crank cleaned up with muriatic acid and I polished it to a shiny finish the governor gear never exploded and is intact I am not sure what else to check on that.

I have a 27 hp Briggs v twin with aluminum rods. I broke a rod so I am rebuilding it. It goes to my lawn mower. Can you tell me what to look for in terms of clearance between my rod and crank journal? If the clearance is too much, can I mill the rod halves to make the large rod journal smaller...

This is what I was talking about

Not outside the pan

Broken rod. Is that open area below the stub the pto shaft goes through look right?

I have tried to post images but it always says they are too big. I only am able to use my phone I do not have anything else

Anybody? I am talking about what looks like a hole…..

Does this look right? https://postimg.cc/gallery/1ngCVnv This is a 4409 77 0113 G5.

This started with me repairing a sump pan gasket oil leak. This was my dads lawnmower before and he gave it to me. He had the sump gasket repaired at dealer. Two years later it leaked again so he gave to me and he bought a new mower. anyway, I bought a sump gasket kit that came with a pto seal...

All I am saying is I have had trouble with seals in cheaper kits. I wonder if it is really needed to replace.

I am rebuilding a Briggs v twin 27 hp 49 series after the rod broke. Buying a gasket kit on Amazon. The kit comes with new valve seals but should I use them? The engine did not smoke when it broke the rod. I am a little afraid of replacing my valve seal with a made in china seal if that makes...

There were six marks on the bolts so I assumed grade 8….

I thought some type of lock tight was supposed to be used?

Did the torque spec change? What was it?

This is the problem this engine had. The factory sump bolts are fully threaded. Did you use partially threaded bolts from the farm store?

It’s a used rod I am using

I am rebuilding a 49 series v twin 27hp that broke a rod. Can the head bolts and rod bolts be reused? Or are they torque to yield? Can regular grade 8 bolts be used instead?

I can’t add a photo. It always says file too largest do you mean oil pump alighned

I can’t add a photo. It always says file too large

I replaced the sump gasket due to an oil leak and it immediately broke a rod shortly thereafter. I remember when I did the gasket having difficulty with putting on a new oil seal. If I put the seal on the sump cover first and then tried to install the sump cover the seal lips would curl and mess...

I have a Briggs v twin town appart. Is there a way for me to check if the crank is bent at home? I have a dial indicator but can’t quite figure out how to do it. Any help is appreciated!

I would like a lawn mower tach and hour meter mounted to the dash of my zero turn for tuning/ maintenance purposes as well as an oil pressure gauge. Concerning the tack, the only thing I have found runs on batteries. I would like something that wires to the lawn mower batter so I do not have to...

Would this one work? https://www.facebook.com/marketplace/item/683035752948319/ only thing is mine is a choke o matic and this has a separate choke

Would this be a decent engine and powerful enough for my 54 inch zero turn? https://www.smallenginewarehouse.com/44N677-0037 I forgot to mention I have the choke o matic on my mower.

Thanks so much! Just a couple of additional questions…. 1. The cylinder with rod that did not break (cylinder 2) had 130 psi of compression, which I assume is good. Does this mean it is Lilly in spec? I know I have to check but how can an out of spec cylinder have excellent compression? 2. What...

What exactly is “reject size” compared to standard size?

A piston is 100 dollars and a rod not far from that. Rings are 40 bucks for one piston. I want to use all new parts but it adds up.

I can not get an engine for this for 595 bucks

Typically when one of these is not rebuildable, what typically is wrong with them to make them that way? I am not done working on crank. Are the bearings in the block the cam rides in replaceable?

I will say I tend to keep and repair everything I own. I once had a truck with 370,000 miles on it. This is the nicest mower I own. I really just can not afford a 1000 dollar engine and it looks like I will be watching every penny for the next 5 years or so untill kids complete school. I do have...

No. I see no other damage other than destroyed rod and piston.

I have a John Deere z655 54HC that was given to me last year by my dad when he got a new one. The only issue he had with it while he owned it was an oil leak. He had the John Deere dealer fix it. Well, it happened again so he gave to me. I mowed with it last year and it ran great, I just had to...
