375hp banshees Posted October 9, 2007 Report Posted October 9, 2007 just the standard 8mm zerk used... i wish i knew the pitch and all that but i dont i know you wanted exact but, this is what i found: all mine show 8x1 use 7.20mm bit = 9/32(7.14) Quote
Bansh-eman Posted October 9, 2007 Author Report Posted October 9, 2007 ok im going to have to do more searching, casue thats not ringing a bell. ill be damned if i drill the wrong size Quote
BellicoseBanshee Posted October 9, 2007 Report Posted October 9, 2007 I'll be damned if I drill the wrong size Oh come on, what is a few extra holes...hehehe...:biggrin: Quote
CFM Posted October 9, 2007 Report Posted October 9, 2007 Get over to your local Fastnal, get a 10-24 tap and drill, pilot point first and have at it... They also have the zerk fittings. That's what I put in all my swingarms... Quote
Bansh-eman Posted October 9, 2007 Author Report Posted October 9, 2007 awsome there is one right by my house... i need to find a press though i dont trust my hands to drill them straight Quote
brian Posted October 9, 2007 Report Posted October 9, 2007 If you have no access, you can get it done without a press. Just make a good mark with a center punch and use a #2 center drill to start the hole. the larger drill will follow no problem. Quote
ClimbAnyHill Posted October 9, 2007 Report Posted October 9, 2007 (edited) Hey.... Harbor Freight sells an assorted zerk box with a bunch of diff sizes.. I bought one for $9 and all sizes included.. Should you mess up then step it up to the next size, the Zerk heads are same size for your grease pump! Edited October 9, 2007 by ClimbAnyHill Quote
Bansh-eman Posted October 9, 2007 Author Report Posted October 9, 2007 (edited) yea im going to hit up that Fastnal place and get all the shit i need. i only need to make 4 zerks o im not going to bother with a shit ton of them. i just wasnt too sure that a center punch would make enough of a mark in 4130 chromoly to start a hole with a hand drill. i need to get another grease gun, i got one last year and the damn thing didnt seal around the zerks and grease went everywhere Edited October 9, 2007 by Bansh-eman Quote
swrbansheeboy Posted October 9, 2007 Report Posted October 9, 2007 you can always grab a piece of scrap steel and drill and tap it to make sure it works before you commit yourself on the stuff that matters... Quote

But the key is going to be in using that #2 center drill. You can probably pick up a good HSS one for $2-3 at your local industrial supply store. Quote
Bansh-eman Posted October 10, 2007 Author Report Posted October 10, 2007 ok guys im scrapping the zerks but incase anyone wants to know... the most common zerk at a store like Fastnal is going to be a 1/4-28 zerk. for this you will need a #3 drill bit and a 1/4-28 tap. cheers Quote
