User questions & answers

Question: If i was to put this motor onto a mini bike with a head and tail lgiht would this be able to keep the light running? Or charge a battery
Answer: They all came keyed the same
Question: What type of motor oil
Answer: Yes, all 4 were keyed alike, a pleasant surprise
Question: Is There a conversion kit for 120 Volt Starter
Answer: Yes, all 4 of mine were keyed alike
Question: One person said that the carberator is not set up for the cable system on a go kart so how could I make it work on my go kart.Thanks
Answer: I found the metal gussets barely adequate for a 10ft wide shed. And the metal parts to hold the studs were not at all adequate - the side walls wanted to bow once the roof was on, so had to toe nail them also. The gussets at the top of the side walls direct the weight with more of a lateral component then vertical, and the side walls studs do not nail directly into the 2x4 at the top which is at an angle in the gusset there. That angle also makes putting inside walls up a hassle - the metal gussets slant across the top of the inside wall at an angle which is different from the angle of the 2x4's of the roof/ceiling, so you have to cut a notch for the gusset to extend through on the inside wall and the inside ceiling, and then figure a way to cover that metal gusset. If you look carefully at the image you'll see what I mean. If you are not going to have an inside wall or ceiling, not an issue.

User questions & answers

Question: Does this have warranty
Answer: I was told every OTC hand tool has a warranty
Question: Will this work for 08 lmm
Answer: My engine is an older duramax so probably not
Question: Will this tool work for a lbz duramax
Answer: I don't think it will fit as it is made to fit the internally mounted LB7 injector with a larger hold down opening, the OTC 6779 Injector Puller found on Amazon to replace GM Special Tool # J-46594 is for the externally mounted LLY, LBZ, and LMM injectors with the smaller hold downs.
Question: What is this tool made of? The picture make it look like resin
Answer: It is made of steel but to be completely honest I didn't even use it for the fact ur likely to remove the injector cups as well I help out a buddy who is a ase mechanic and he said" the hundreds I've replaced ive never used a puller" he showed me u just stick a pry bar behind the thickest part of the injector out a little pressure then just wiggle back and forth and they will pop right out
Question: Will this fit 2004.5 lly duramax
Answer: Yes. Fits all LLY!!
Question: Does it come with a gasket
Answer: Yes. And new bolts for installation
Question: Will this fit a stock lbz? No lift

Question: Does it fit under the OEM skid plate
Answer: Yes. If it fits over the cross member it fits over the skid plate as this good plate bolts onto the crossmember.
