45 minute timing belt ?

[3bears]

so on another forum, a person said he can do the v6 timing belt, tensioner, waterpump and cam seals in 45 minutes, start to finish. Maybe with all the tools right there, it can be done. I am not saying it can or cant be done, my last one took me nearly half a day, but it was the first time doing one on these motors went slow and double and tripple checked everything. Had one stripped bolt.

when you consider some shops charge up to 500 or more labor, to do it in 45 minutes would make some serious cash.

so without arguing it can or cant be done in 45 minutes, what kind of time frame do you guys figure it takes. ( will be doing all this in a few months )

Bump. I’d be interested in this too.

It took me all weekend because everything fought me taking it apart and required a trip to the junkyard to replace broken bolts and tensioners from rust.

Draining the cooling system isn’t a 5 min procedure. Let alone cleaning all gasket surfaces prior to assembly.

Yea, you could pull the lower hose and let the coolant dump on the floor and not care about clean gasket surfaces.........

Draining the rad and pulling it, figuring out how to remove the belt tensioner without removing the AC compressor and mount.....

The techs who get it done in 45 mins really don't care about your vehicle if you think about it deeper. All the old gaskets has to be scrapped off and the fact the bolts can strip makes it even longer to get the job done.

Well, I've got pneumatic gasket scrapers & die grinders with wire cups that make short work of gaskets. I've also got impacts and air ratchets. An experienced tech will know what bolts are common issues and have spares available. Yes, things can and do go wrong, but sometimes experience trumps Murphy and things get done quickly.

Caterpillar quotes 275 man hours to rebuild a 398TA engine. I regularly rebuilt them in 200hrs or less from the time I pulled them off the truck to the break in runs after having painted them. Experience, tools, and spare parts make a huge difference.

Thats very true. I was really thinking about those backyard mechanics who don't do these often lol. I haven't done mine yet but I do expect to get it done in a full day or so.

First time - 8hrs
Second- 5hrs
Third- about the same.

Personally unless I am working at flat rate, which I don’t in my profession, time wouldn’t matter to me on this job. To get all the bubbles out of the coolant system correctly is a fifteen to twenty minute job unto itself.

It took me 8 hours to do the Timing Belt, Water Pump, new Pulleys, Tstat, Radiator Hoses, Radiator, Coolant Flush and Trans Flush:

Timing Belt
Crankshaft Pulley Bolt
Idler Roller
Tensioner Roller
Water-Pump (w/gasket)
Thermostat
Thermostat Gasket
AC Compressor Belt
Alternator Belt
Power Steering Belt
Radiator Hose Upper
Radiator Hose Lower
Toyota Red Coolant
Dipstick Tube O-ring
Radiator
Crankshaft Oil Seal
Transmission Fluid


I think 45 min is a bit rushed no matter what tools/experience someone has. Some things just take time (like bleeding the coolant).

I will say though, nothing fought me (all bolts came off buttery smooth) and everything went by the book. It's also one of the easiest jobs I've done on any car I've owned (which is why I ended up replacing so many parts since I saved so much money DIY).

Doing just the TB/WP/Tstat and bleeding the coolant, I could do in 1.5-2 hours max. That assumes using the same hoses, belts, pulleys. I had all the necessary tools though and again, nothing fought me. (SoCal car=no rust).

It's kind of like the lower ball joints, I bought the tools for that and could now do both sides in 60 min.

I'll be less politically correct because it's my style. I call serious bullshit on being able to do this job properly in 45 minutes. There's just way too many steps to perform to be able to do a job like this in that little of time.

This is a case of somebody grossly misrepresenting how long a job actually took them. Like [MENTION=69868]LittleCaesar[/MENTION] mentioned, it takes a decent amount of time just to properly burp the cooling system. Anyone saying they can do a timing belt job on one of these engines in 45 minutes is either full of shit or potentially making serious errors while doing it.

Even with experience doing this job once before, I doubt I could do it any quicker than what [MENTION=69868]LittleCaesar[/MENTION] said, about 5 hours. I take my time so I don't make mistakes. No way would I want a mechanic doing this job on my rig in 45 minutes. I would expect cross threads bolts and nuts and most likely be faced with leaks from something like the water pump because they rushed the process of getting the block surface really clean for the new water pump and gasket. Take you time and do the job right the first time. It will save you time in the long run.

Lol 45 minutes of busted knuckles

Draining the cooling system, compressing the tensioner and just replacing the belt only.........

45 minutes! Doubt it. But if you ever get a chance to go to top fuel races get a vip pass so you can see the crews rebuild a complete 8000 hp engine, clutch and tweak the chassis in about 75 minutes. It is astounding and amazing to see those guys do their job. There is always a crowd just watching intently.

The last time I did mines it took me 11 hours, from start of disassembly to buttoned up, burped and running. I took my sweet time using just non power hand tools as I did it in a friends driveway.
I'm sure with a sense of urgency and using power tools the job can go quicker, but I didn't want to stress myself if I didn't have too over the job.

It may take 1/2 day just to get the harmonic balancer off[emoji12]

I have done this plenty of times. But I will log my time this weekend when I do mine again.

I am a profesional and have all the tools and a lift and air pressure.

I won’t zip thru it on purpose but I know where all of the bolts are already so it should be As fast as I can be while still doing it properly

thats 100% bs, no way. I mean it takes that longer than that to get all the pullys and radiator and shit off.

I'd like to see the video of someone doing this in 45min, even if it's brand new or just assembled and then this job was redone I don't think this is possible, a engine on a stand and not doing the water pump and accessories it sure is possible, and that's where this 45min tbelt fantasy job is coming from, otherwise impossible on a used motor with other related components that need to come off and back on and drive down the road. And then like said throw in a stuck harmonic balancer and you can forget that pipe dream.

 

[Malcolm99]

Double post

Its a 45 minute job with the engine on a stand... A couple small electric impacts and plenty of clearance would make it easy.

Basically this is easy:

And this is a giant pain by comparison:

With an air lift type tool it's a 5 min procedure....


I think I had a total of about 4 hours into my first one (2nd doesn't count as it was on an engine stand). If I were to do it again and again I could probably get it down to an hour and a half to an hour- and I'm not a professional mechanic.

As an example of experience- for a first gen MR2 I could drive one into the garage and have the engine/transmission out completely in 90 minutes. I could get it back in around the same time. (I had an old time lapse years ago). Most people who have these it is a weekend project and most mechanics don't even want to touch them.
