I have heard that it is much easier on the A5's than the older models. May not cost less though. Reading through the Bentley manual, it still seems pretty involved.
Exactamundo! The transmitting of vibration differently = much quieter operation. Later!zanakas said:Belts have two advantages... they don't stretch like a chain, allowing for more precise timing, and they transmit vibration differently...
VW has a kit for $192, the part number is 038 198 119A. The water pump lists for $165 (part number 045 121 011F) and it doesn't look like there is an aftermarket alternative yet.2footbraker said:Is there a kit available for the A5?
I just sold my first A5 BRM Deluxe Timing Belt Kit to a fellow in North Texas who has 102K on his '06 Jetta. Not much magic to it, really. The water pump changed a little and the serp belt is shorter due to the engine not having a power steering pump but other than that it was very similar to the BEW PD engines. There was one engine mount stretch bolt that retailed for $9.28! It had a 6mm stud integral to the 16mm head.2footbraker said:Is there a kit available for the A5?

Since when? Belts are used mainly for 2 reasons, Noise and price. Perfect example, On toyota's newest generation 4 cylinder corolla, camry, celica etc. they had to use a chain in order to get through emissions regulations. A belt flexed too much not allowing the precise cam timing needed at the higher rpm it runs at.zanakas said:Belts have two advantages... they don't stretch like a chain, allowing for more precise timing, and they transmit vibration differently...
When was the last time you saw a non OHV car? Flat heads went out a long time ago. OHV or overhead valves have been around for a long time. All import cars use OHC or overhead cams currently and the American manufacturers are also starting to switch over. Belt replacement intervals are increasing, that is true but chains still go longer. Labor isn't really the problem depending on the engine to quote Motor's Labor guide a t-belt replacement on an ALH is 4.0 hours (Belt ONLY) while a chain on a 98-01 Corolla with A/C is 2.9 hours. The costs are the gears and chain as well as the adjuster and guides.bhtooefr said:8606: Well, chains can be better in an OHV application, just like belts can be better in an OHC application.
However, belt change intervals are lengthening as time goes on (due to improvements in rubber technology), and (as more and more engines go to OHC) chain failure rates are increasing. Chain replacement labor costs MUCH more than belt replacement labor.
I should revise my statement. Through the working life of the belt, a belt (versus a chain) should introduce less play than a chain. Belts do not stretch (contrary to some opinions), and a synchronous belt should not "drift" timing at all. Wear on a chain (especially roller varieties), will eventually introduce some "slop"...hevster1 said:Since when? Belts are used mainly for 2 reasons, Noise and price.

Still waiting to hear back from the customer to see if the Metalnerd PD tool kit had everything required to do the job. I have not reviewed the procedure. The tensioner, belt, and roller are the same between all PD engine codes.zanakas said:Are the BRM tools the same as BEW?
The BEW engine needs the T10050 to hold the crank. The BRM may need the T10100 to hold the crank depending on which crank pulley it has. To tell the difference you have to look at the pulley. If the TDC mark is at one of the bolt holes (as pictured in the BEW procedure I posted), it uses the T10050. If the mark is between bolt holes (1 o'clock position with engine at TDC), then it uses the T10100.corrado tdi said:Still waiting to hear back from the customer to see if the Metalnerd PD tool kit had everything required to do the job.

I think the parts cost about 300. Did one last week. It was an 06, the guy put 95k miles in 9 months. The top 2 horizontal bolts for the engine mount to the engine block are longer than the other engines. You can remove the engine mount on the BRM engine. I will post some pics and more info later.8606 said:Some manufactures are going back to timing chains. If timing chains can cause damage like belts why would they go back to that design? Up till this thread, I thought timing chains were better than belts.
Here's the scary question (I don't believe anyone has asked yet). What can we expect to pay for a new timing belt installed?
The crank lock is different if it is a BRM uses t10100 for oval crank gear and t10050 for the BEW round crank gear. My local dealer said he could order the t10100 but I got mine from Metalnerd. I didn't see MoGolf's reply before I posted.zanakas said:Are the BRM tools the same as BEW?
Which Toyota V8 uses a chain?oilhammer said:hevster, the new Toyota V6 and V8s use chains as well. Is your TIS access up to date?
Both the 4.6L and the 5.7L each have a nightmarish network of FOUR chains, as do the 2.5L, 3.0L, 3.5L, and 4.0L GR series V6 engines.gquenstedt said:Which Toyota V8 uses a chain?
Learn something new every day. The only Toyota V8 that I have experience with is the 4.7 in my Tundra which has a belt. But the new 5.7 in the Tundra has 2 chains. That is an interesting design change.oilhammer said:Both the 4.6L and the 5.7L each have a nightmarish network of FOUR chains, as do the 2.5L, 3.0L, 3.5L, and 4.0L GR series V6 engines.
There will also be a 5.0L chain drive V8 soon.
The 5.7L has 4 chains. One each for each bank, then a cam-to-cam chain on each bank. They did away with the [much simpler] gear drive for the cam-to-cam setup mainly due to the double VVT arrangement, which I am pretty sure the 5.7L uses as well.gquenstedt said:Learn something new every day.
