| Getting ready to install new valve guides in son's D10 III, rebuild. The new ones from reliance, seem to be knurled at one end. My question is, is that the end that's at the top ?? Also has a line bout 3/4 '' toward one end, I guess that's for depth but thought I'd follow the manual, says use straight edge & make them even with valve cover mating surface. Any help appreciated, keith so. va. |

I've made a bushing the correct length that will only allow them to press in to the correct height. ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits. If you can't make it GO... make it SHINY |

The Knurling would go into the head. That's what holds them in place as they are most likely made in China somewhere and they didn't convert inches to MM correctly. The OEM guides are the correct size and smooth from end to end. ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits.

I would assume that it goes in knurled side to the inside. you may want to search the internet using more specific terms that I did. I entered "installation of knurled valve guides" into YT and one of the first videos to come up was this: https://youtu.be/OCLucg2SC7Q?si=EhAYpKcXwqZ30z1U" rel="nofollow - https://youtu.be/OCLucg2SC7Q?si=EhAYpKcXwqZ30z1U ------------- Source: Babylon Bee.

Yikes! Brand new valve guides that are already knurled?!?  Knurling valve guides was a common way to get a bit more life out of a worn-out engine when parts were expensive and labor was cheap back in the bad old days and everyone was happy if a car engine went 60,000 miles. Perhaps I am missing something or I am merely confused

I'll second Les on this... knurling on the INSIDE is done as a temp fix for wear. if it's on something from China, I'll bet that what they did, was pull out guides from an old head, and copy them... knurling and all...  ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem. Citrus hand-cleaner with Pumice does the rest. |

The AGCO valve guides I bought for my WD had spiral marks inside of them - I presume for oil control, with no seals? The old ones I took out also had them. ------------- 1939 B, 1940 B, 1941 WC, 1951 WD, 1952 CA, 1956 WD-45 |
