Maverik Posted June 24, 2021 Share Posted June 24, 2021 Brain trust, Just about to replace timing belt and I had a new bottom pulley/gear (ERR1642) too. Its an Allmakes component made in China (from the box). for a gear driving a rubber type belt I though the finish on this was quite honestly carp. Before I send it back I thought I'd like a 2nd opinion. I'd be expecting a much smoother finish on this gear? - anyone got any thoughts?

vulcan bomber Posted June 25, 2021 Share Posted June 25, 2021 Doesnt look great at all does it. I'd be inclined to send it back. They should have a polished finish. Not look like they were cut with a blunt tool going backwards. Quote Link to comment Share on other sites More sharing options...
Troll Hunter Posted June 25, 2021 Share Posted June 25, 2021 ^^^^^^ Agreed. Not acceptable for what should be a finished product. It looks as if it missed the last couple of stages of preparation. Mike Quote Link to comment Share on other sites More sharing options...
missingsid Posted June 25, 2021 Share Posted June 25, 2021 Looking online it is not very clear but certainly blue box ones are not a polished finish. However the rippled finish does not look good? I did find a pick of a genuine version but the pick was not clear enough to tell. Quote Link to comment Share on other sites More sharing options...
Snagger Posted June 25, 2021 Share Posted June 25, 2021 The seal land looks bad, too. I had Britpart swivel housings with the same dire surface finish. All makes are part of Britpart, I think. So much for the claims they’re improving their game. Quote Link to comment Share on other sites More sharing options...
Maverik Posted June 25, 2021 Author Share Posted June 25, 2021 It wasn't the cheapest on the shelf at £29.95 but I've got to say I was expecting a little more. - Looking last night I found I could get a genuine one for £80 from the land rover classic parts website. This kind of stuff drives me nuts, its half a job, why make something like this and just not finish it properly. Back in the post. Thank you all for your collective views.

monkie Posted June 25, 2021 Share Posted June 25, 2021 This is shocking. I would say this is good evidence that one of the many reasons some pattern parts are cheap is the lack of quality control. I'm amazed that was ever put in a box and sent out the door. Quote Link to comment Share on other sites More sharing options...
missingsid Posted June 25, 2021 Share Posted June 25, 2021 Does anyone have a pic of new genuine one for comparison as I am only seeing a one sided view at the moment? A used one will be polished by the belt so it needs to be a brand new one please. Quote Link to comment Share on other sites More sharing options...
smallfry Posted June 25, 2021 Share Posted June 25, 2021 The original item was sintered, so the teeth would not have been machined at all. Quote Link to comment Share on other sites More sharing options...

That is what I was expecting to hear. So is there a problem with the original posted item quality? I am confused if the post is about the sinter finish quality or the fact that it is sintered and not smooth/polished/machined finish?

The original, genuine part was interred, but the new pattern part in this discussion is machined. The machining may have been done adequately to initial tolerances, but it clearly hasn’t been finished as the tool marks are still very coarse - the seal land is heavily grooved and will destroy the seal rapidly, and the grooving of the teeth is rough enough that I’d expect rapid wear of the timing belt. That is what is being discussed. Quote Link to comment Share on other sites More sharing options...

Their prices are very fair, and they have a reputation to protect. Quote Link to comment Share on other sites More sharing options...

Nope, just thought you had gone off on a tangent ! If you pump the Turners photo up, it still looks like machining marks on the belt teeth to me ? Maybe its only poor photo resolution.

Snagger Posted June 27, 2021 Share Posted June 27, 2021 I think it’s the photo resolution. Look at the striations to the left of centre and you’ll see they’re parallel on screen to the striations on the right, not the teeth. Quote Link to comment Share on other sites More sharing options...
Maverik Posted July 2, 2021 Author Share Posted July 2, 2021 Took a bit of a punt £6 - new old stock - looked to be an early bearmach offering, and it came in a bright green bag, I've had other stuff in similar packaging and it's always been pretty good, out of a UK based machine shop if I remember rightly. Anyways much happier with this. Massive difference from the first offing. Quote Link to comment Share on other sites More sharing options...
monkie Posted July 4, 2021 Share Posted July 4, 2021 I am expecting a new one to arrive on Monday from Turners. I will see how it compares to your pictures. 1 Quote Link to comment Share on other sites More sharing options...
monkie Posted July 6, 2021 Share Posted July 6, 2021 My delivery from Turners has arrived this morning. Here is the 200Tdi crank pulley supplied by them. The seal surface has a fine finish to it. The teeth feel smooth but look similar to your first picture. Quote Link to comment Share on other sites More sharing options...
reb78 Posted July 6, 2021 Share Posted July 6, 2021 Wow. Those teeth look rougher than the first photo! Quote Link to comment Share on other sites More sharing options...
Snagger Posted July 7, 2021 Share Posted July 7, 2021 Look closely at the nature of the surface of the teeth, not just the depth of the roughness, and you’ll see the Turner part has very rounded texture while the Britpart item has sharper grooves cut in its surface. The first will do no significant harm to the belt, but I think the second would shred it. Quote Link to comment Share on other sites More sharing options...
smallfry Posted July 7, 2021 Share Posted July 7, 2021 Hmmm. Doesnt look great though. If I had to make the choice, it would have to be the green bag one. Tough call. Do you have a buffing wheel ? 1 Quote Link to comment Share on other sites More sharing options...
